Price / Value FAQ Answers to questions
Q:  What value does Insuladd add? A: Insuladd® superior insulating paint additive reduces the demands placed on conventional insulation which may have been poorly installed or have deteriorated due to dampness or age. Insuladd® can be easily and inexpensively applied to walls and ceilings by adding it to paint.  By slowing down the transfer of heat through the surface to which Insuladd® has been added, a home or building becomes increasingly more energy efficient, as less use of power driven heating and/or cooling devices is required to maintain a 'comfort zone'.
Q:  How much does Insuladd® cost? A: An Insuladd® pouch which mixes into 4 litres of paint retails in New Zealand for $54.95 (Incl GST).
An Insuladd® Box which mixes into 20 litres of paint retails in New Zealand for $247.25 (Incl GST).
Bulk orders are subject to negotiation. (A two coat application of Insuladd® for approx $2 per sqm2.)
Q:  Is painting with Insuladd a good investment? A:  Definitely. Insulating your home and doing it as effectively as possible is always a wise investment.  Around 60% of heat loss and gain in a home (or building) is through the walls and ceilings, so insulating them can be one of the most cost effective ways to reduce the money being spent on running your power guzzling heating and cooling devices.
Once applied, Insuladd® can make your living or work space temperature more comfortable naturally, and without the need to continiously run ones heaters or air conditioner. 

Energy wastage is like buying $100 worth of food from the supermarket, coming home and throwing $33 worth of food in the bin every time.  You wouldn’t waste food like that, so why let the money you pay to run heating and cooling devices simply disappear through your walls and ceilings.
Insuladd® is a low cost insulating investment that rapidly pays for itself in money saved.
Q:  Has the market adopted the concept of an additive that provides insulating properties to paint? Definitely. Insuladd is used around the world by multiple companies, institutions, and organisations.
Q:  Why have I never heard about insulating paint? A:  The insulating coatings industry is still a relative newcomer to the energy conservation marketplace.

Only recently has an agreement been signed to import Insuladd® directly into New Zealand.

This is certainly a product that New Zealanders are going to be hearing more about in the future.
Q:  Has Insuladd® been NZ tested /certified? Not as yet, but this will be happening in due course.

Insuladd® does not however require certification to be used as a supplimenting insulation product.

Product FAQ Answers to questions
Q:  What is Insuladd® paint additive? A: Insuladd® Insulating Paint Additive is a Proprietary Ceramic microsphere that is able to reflect radiant heat waves. The additive is in the form of a super fine free flowing powder (like talcum powder), and is designed to mix into ordinary paints to create a reflective barrier on the surface to which it is painted. As heat is reflected away from the Insuladd®, the amount of heat energy able to be transferred through that surface is reduced.
Q:  What is a ceramic microsphere? A:  Each microsphere is in essence a tiny ceramic ball, with an air vacuum inside, and with an outer coating that reflects radiated heat.

As in a thermos flask, the shiny inner surface of the flask reflects heat radiated from a hot liquid back into the flask, whilst the air vacuum between the inner and outer surface limits the amount of heat that can be transferred via conduction.
Q: Who developed the technology? A: Insulating microspheres were originally conceptualized and developed by NASA as a way to insulate against the high temperatures encountered by the space shuttle on re-entry.

This microsphere technology was further developed by David Page of The Tech Traders Company (now Insuladd®) through a joint effort with the NASA Technology Exchange Program.

The insulating composite was formulated for commercial use as an insulator that could be used in paint.

See  Report 1 featured on the NASA website;  See  Report 2 featured on the NASA website.
Q: Are all products on the market equal in their ability to reflect radiant heat? Insuladd is a "Patented" product that is much more than adding a Microsphere to paint.
In fact if it was as easy as adding an air filled microsphere to paint every paint manufacture in the world would be doing it.
Q: How do microspheres work when mixed in paint? A:  Conventional bulk (mass) insulation products only slows down the conduction of heat that has already passed through the surface and into the space where the insulation resides.

The tiny Insuladd®
microspheres pull together to form a 'barrier' as the paint to which they are added dries. The radiant heat transfer is therefore resisted (slowed down) before it can penetrate the painted surface, meaning less heat gets transferred through surface and into the cavity.

It will be well worth your while to understand the 3 different heat transfer modes, and how these relate to the actual effectivness of different types of insulation.
Q: What kind of paint should I use? A:  Insuladd® is an insulating paint additive. It's a powder that can be mixed into almost any standard interior or exterior paint. It is an inert product and will not harm or effect the actual paint in any way.
Q:  I live in a cold climate, will Insuladd® work for me? A: Absolutely! Remember that heat always moves toward cold. The heat inside your home wants to escape toward the cold outside air.

Adding Insuladd® insulating paint to the interior walls of your home will slow down heat loss through the interior painted surface prior to it even getting to the 'mass' insulation, which is closer to the cold outside wall and atmosphere. Insuladd® reflects a lot of the heat already in your home or work space, back into your living environment.
Q: Do Insulating paints work in winter months? A:  Yes! The heat inside your home wants to escape toward the cold outside air! A surface painted with  Insuladd® lays a reflecting film (barrier) that will help stop this outward heat loss and help to lower your heating bills.
Q:  Should I use Insuladd® both inside and outside? A: Yes! For the optimum in energy efficiency it is best to use Insuladd® both inside (to use heaters less in winter) and outside (to use air conditioners less in summer). However, either application alone will give you increased energy efficiency which in turn drives down utility bills!
Q:  Can I paint over Insuladd® at a later date? A: Yes! However, you may want to leave Insuladd® radiant barrier exposed as long as possible because painting over it will reduce its reflectivity capabilities.
Q:  Does the additive contain harmful chemicals? A:  No! Insuladd® ceramic additive is free of all volatile chemicals and toxins and is recognized as safe ("GRAS"), under the Federal Food, Drug, and Cosmetic Act. Non-toxic, odor free, and environmentally friendly.
Q: Can I paint my attic with Insulating paint? A:  Absolutely! By restricting the amount of heat allowed into your attic you reduce the load on your existing insulation, making it more effective.
Q:  Can the insulating additive be mixed into clear finishes? A:  The ceramics are not crystal clear and thus impart a slightly "milky" look when used with clear finishes. This is not so obvious on light colored roof shingles or wood stained finishes. Our best advice is to mix in the ceramics a little at a time until you reach a finish that is acceptable.
Q: Can this ceramic additive be used for deck paint or stain? A:  The insulating additive will help keep the deck cooler while providing a slightly slip resistant surface.
Q:  Can Insuladd® guarantee your utility bills will be cut by 30%, 40% or even 50%? A:  That would be unrealistic, as the results depend on how many areas of your home you apply insulating additive to.

Other considerations to factor in include; amount of attic ventilation, amount of air infiltration into your home, type of roofing materials, existing insulation and on and on.
What can be guaranteed is, that for the $1 per coat sq m it costs to add this insulating additive, one will not find a better solution at the price to combat high utility bills.
Q: Does Insuladd® reduce condensation? A:  Not only is Insuladd® a very effective energy saver, it also dramatically reduces condensation problems.

Insuladd® works by warming up the wall, and because the wall is warmer, the production of water droplets and condensation is dramatically reduced.
Q: Does Insuladd® reduce mould and mildew? A: Mold spreads like any other living organism; it reproduces and grows in moist and damp areas. Where there's moisture, there's almost bound to be mold and mildew. INSULADD® insulating additives for house paint has proven to reduce moisture formation on walls and ceilings and eliminates the key factor for the spread of mold and mildew.
Q:  Do ceramics keep paint from breathing? A: A paint coatings ability to breath is known as "Permeability" which is a measurement of the rate that water or vapor will pass through a membrane. Ceramic filled paints do not restrict a paint coatings ability to "breath
Q: Does Insuladd® additive have an effect on texture or colour? A:  Insuladd Additive will leave a very mild dusty-feeling texture to the surface to which it has been applied, but will not visually affect most wall surfaces.
Insuladd Additive may appear to lighten darker colors one hue.
The additive will flatten the finish of the paint one degree.
For special finishes apply the coats with the additive under the finish coat.
Insuladd additive is inert, and will not affect the chemical properties of the paint in any way.
Q: Where can Insuladd® paint additive be used? A:  Insuladd® insulating paint additive can be used almost anywhere you can apply paint.  The uses are endless, and new uses are continuously being discovered.  Insuladd® can be applied wherever you want to reduce heat loss in your buildings/surfaces or reflect heat from the sun.
Application FAQ Answers to questions
Q: Is Insuladd® paint additive easy to use? A:  Yes! Insuladd® is extremely easy to use, its simply a matter of stirring it into your paint.  It’s literally as easy as 1,2,3.

Step 1 Empty contents of paint into a bucket.
Step 2 Empty contents of Insuladd® into the same bucket
Step 3 Mix together well, and apply to walls/ceilings/surfaces as you normally would.
Q:  Will Insuladd® additive reduce paint coverage? A:  No! It does not reduce paint coverage
Q:  How much Insuladd® do I need? A: You can figure on an average coverage rate of 15 sq m per litre of paint for most house paints on smooth surfaces that need an improvement.

One pouch of Insuladd® mixes directly into 4 litres of paint.
One box of Insuladd® mixes directly into 20 litres of paint.
Rule of thumb is a 1:10 ratio of additive to paint.
Q:  How many coats of paint should I apply? A: For best results, 2 coats of paint with Insuladd® is recommended.
Insuladd is such an excellent insulating barrier, anything more than 2 coats only gives a marginal increase in performance.

Two thin coats of insulated paint are better than one thick.
Allow the first coat to dry completely (between 8 and 12 hours) before applying the second coat.
Q:  How does Insuladd® additive get applied? A:  Paint containing Insuladd® additive can be applied with the usual methods of applying paint such as a brush, roller, paint pad or spray equipment.
Q:  Can Insuladd® be sprayed? A: Yes! But since Insuladd® is a powder additive, simply remove all filters from your spraying equipment or the insulating additive will be strained. It's also best to use a larger than normal spray tip.
One can use any airless paint sprayer that will produce at least 2500 psi and support the tip sizes listed (.617-.62).
Q: How do I mix the ceramic additive into my Paint? A: The ceramic microspheres are a very fine powder and blend into paint quite easily with a simple stirring using a paint paddle.
Add the Insuladd Additive gradually to your paint while stirring to avoid clumping of the ceramic microspheres in the additive.
Always stir your paint for a minute or two prior to commencing painting if the paint has been sitting for more then 2 hours since last used.
Q: Will the additive affect the paint's properties and adhesion? A:  Insuladd additive is inert, and will not affect the chemical properties of the paint in any way.
Q: How should one add the additive to paint? A:  Volume will increase by 20%. When adding a ceramic powder additive to a full can of paint, do not add the powder directly into the can of paint. Use a plastic bucket or painter's can that is larger than the container of paint. Gradually pour the paint and the powder into the plastic bucket stirring continuously to avoid clumping.
Q: How regularly should one mix the paint and additive? A:  If you leave the mixture sitting more than two hours for any reason, stir well to ensure that the additive is well blended. Most of the powders are easy to blend with paint; however, if left sitting you do need to stir the paint for a minute or so before resuming painting.
Q: How should surfaces be prepared? A:  As with any painting project preparation, remove loose and peeling paint, sanding edges, prior to applying the new insulated paint. Walls should also be free of surface oils and rust stains and you should spot prime as necessary.
Q: How should an existing glossy surface be handled? A:  Enamel paints and other glossy surfaces develop an impermeable surface, which is very difficult for new paint to adhere to when applied over the glossy surface. In order for the insulated paint to give you the best performance, thoroughly sand the glossy surfaces prior to painting. Wipe clean with a damp rag to remove dust after sanding.
Q: How should wood be handled? A:  If you are painting wood with insulated paint, always coat any wood end grain prior to painting. Furthermore, never coat wood when its moisture content is higher than 17%.
Understanding Heat Transfer, Insulation and R- Value FAQ Answers to questions
Q: How exactly does heat get transferred? A:  Heat is transferred in 3 ways.

Conduction -  is the transfer of heat between two objects in contact. The transfer occurs as the fast-moving molecules of the hot object bump into the slower-moving molecules of the cold object. The fast molecules give up some of their energy, slowing down, and this energy goes into speeding up (and thus heating up) the slow molecules.

Convection - A cool fluid or gas in contact with a warm solid will heat up through conduction. The warmer fluid or gas drifts into the cooler fluid, setting up a convective current.

While circulating inside of a wall cavity, air removes heat from a warm interior wall, and convects it to the colder exterior wall, where it loses the heat.

Radiation -  In this case, heat moves through space without the assistance of a physical substance. This is how the Sun's heat reaches the Earth. The radiated heat is transferred directly into a solid object, but it passes readily through transparent materials such as air and glass.
Q:  How do standard forms of insulation work? A:  Conventional insulation materials like fiberglass, cellulose, rock wool and Styrofoam, no matter how thick, have almost no ability to block radiant heat energy which can account for as much as 93 percent of summer heat gain and up to 75 percent winter heat loss in conventional structures.

Conventional (mass) insulation works by trying to " trap " the heat in air pockets contained between the fibers in the product. Air is a good insulator against conduction, but once mass insulation becomes saturated with all the heat it can absorb, the heat is then transferred on through the wall or ceiling.
Q:  How does paint insulation work? A: Insuladd® hollow ceramic microspheres, when mixed into paint create a ' RADIANT ' barrier.

A 'radiant barrier' is essentially 'a material' placed in an airspace to reduce heat transfer between a heat-radiating surface (such as a hot roof or warm interior wall or ceiling) and a cooler, heat absorbing surface such as standard insulation materials (Yes, insulation Absorbs Heat!) and the surface on the opposite side of the insulation.

In the case of radiation, the need is for intervening surfaces to be highly 'reflective' so that
heat radiation bounces off, rather than being absorbed.
The concept is similar to how a thermos bottle works. The shiny mirrored surface reflects heat back toward the source. Hot things in a thermos stay hot because heat is reflected back toward the hot contents. Cool things inside a thermos stay cool because the heat from the outside is reflected away from the contents.

This is much the same principle that enables a radiant barrier product like Insuladd® to greatly reduces the AMOUNT of the radiant heat that the walls, ceilings and roofs can absorb, heat that one is either trying to keep in during cold winter months, or keep out during warmer summer months!
Q: Does Insuladd® have an ' R-Value ' rating? A:  There is no common ground between radiation energy transfer and conduction transfers because they are separate heat transfer modes. As a result, comparing R-Value of ceramic insulation coatings with the R-Value of conventional mass insulation is not possible.

This is probably one of the most misunderstood values in construction today, and here is why.

R-Value is a measurement of how well insulation performs against conductive heat loss. It represents resistance to one square meter of the insulation to a ONE DEGREE TEMPERATURE DIFFERENCE.

In other words, in a laboratory setting, a piece of insulation is placed between a warm surface of, say, 72 degrees, and a cool surface of 71 degrees. The time it takes for the cool surface to warm up to 72 degrees is the basis for how R-Value is calculated.

Because the R-value system only accounts for the abilities of insulation against conduction, against the other two forms of heat transfer (convection and radiation) the effectiveness varies greatly depending on the type of insulation.

For fibreglass, the results of these tests change dramatically under even slightly different conditions:

-  If 1.5% humidity is introduced, fibreglass loses roughly 35% of it's R-value, due the fact that water is a much better conductor than air.

- All tests are done only at temperatures in which fibreglass would perform best. Above and below this temperature fibreglass rapidly loses effectiveness and the R-value is lower.

-  Air movement also greatly affects the R-value of fibreglass, as heated air moving through the fibreglass drastically reduces it's conductive value.

R-value testing methods do not reflect real world conditions, which can vary greatly with regard to factors like material humidity, temperature differences, and air movement.

Unfortunately these same tests are still used today, despite the fact that new insulations have been introduced into the market.

If stopping radiation was included in R-value testing, heat reflecting radiant barriers would definitely outperform standard mass insulation products.

However, that does not mean that you can't also add a heat reflecting radiant barrier to your structure, and reduce the amount of energy that travels in the form of radiation. 
Q: Is it possible to compare apples with apples when it comes to different insulation technologies? A:  Because there is no common ground between radiation energy transfer and conduction transfers (because they are separate heat transfer modes), an R-value comparison is not really comparing apples with apples.

You may however be interested in reviewing a test by Geosciences to calculate the equivalent “R-value” derived from the addition of INSULADD® into ordinary paint. Geoscience calculated an equivalent “R”of “6”. (
Please however see the section on R-Values).

Tests have been performed on 1" thick materials with a known R value and then compared with the same material coated with insulating ceramic reinforced paints and the difference between the two is equal to an average of 35% reduction of heat transfer.
Q: How are 'Radiant Barriers' valued? A:  Radiant barriers and reflective insulations work by reducing heat transfer by thermal radiation.

All materials give off, or emit, energy by thermal radiation as a result of their temperature.

The amount of energy emitted depends on the surface temperature and a property called the "emissivity" (also called the "emittance"). The emissivity is a number between zero (0) and one (1). The higher the emissivity, the greater the emitted radiation.

A closely related material property is the "reflectivity" (also called the "reflectance"). This is a measure of how much radiant heat is reflected by a material. The reflectivity is also a number between 0 and 1 (sometimes, it is given as a percentage, and then it is between 0 and 100%).

For a material that is opaque (that is, it does not allow radiation to pass directly through it), when the emissivity and reflectivity are added together, the sum is one (1). Hence, a material with a high reflectivity has a low emissivity, and vice versa.

Effective radiant barriers and reflective insulation materials generally have high reflectivity (usually 0.9, or 90%, or more) and low emissivity (usually 0.1 or less), and must face an open air space to perform properly.
Q: What capabilities does Insuladd® provide?
1.  Insuladd® has a high capability to repel radiant heat, thereby blocking transfer on average of 95% of the heat load created as a result of all three types of radiation:

- Ultraviolet radiation (UV) represents 3% of the heat load. Insuladd® blocks up to 99% of UV radiation.

- Visible light (high-frequency radiation) represents 40% of the heat load. Insuladd® blocks up to 92% of visible light radiation.

- Infrared radiation (IR) (low-frequency radiation) represents 57% of the heat load. Insuladd® blocks up to 99% of IR radiation.

2.  Insuladd® additionally has the ability to guard against the transfer of non-reflected heat.   Insuladd® ceramic barriers are comprised of spherical shaped microscopic ceramic particles. The spherical form enables the ceramic to fit very closely together, and thus prevents airflow through the structure.
Insuladd® therefore blocks all three modes of undesired heating (Radiation, convection and conduction).

3. Insuladd® additionally has high emissivity, allowing it to shed excess heat which was able to remain on its surface.
Q:  What savings can you expect as a result of adding Insuladd®? Real life Energy Surveys find that the energy savings realized from the inclusion of Insuladd into interior house paint ranges from 10% to 22% depending on the type of construction, location, and exposure of the home.

Bear in mind that an energy savings increase of only 10% in actual heat flux (heat loss) however, can equate to a much greater increase in actual energy savings, due to the increased amount of time that a radiant barrier like Insuladd helps a homes or workplace interior remain in the “human comfort zone”.

The energy cost savings one gets from Insuladd® makes it a really good investment when applied at time of painting.
Q:  What are some really good reasons to add Insuladd® insulating additive when painting? Insuladd® Thermal Barrier treated microscopic hollow ceramic spheres  incorporated into regular paints and roof coatings cure as the coating dries into a super thin, highly compact and efficient insulating barrier.

Insuladd® Thermal Barrier insulating additive is the only product of its kind proven over and over again to be able to make house paint reflect heat and perform as a radiant barrier.

The Insuladd® Thermal Barrier insulating additive forms a "high-emissivity" coating which quickly radiates any absorbed solar or radiant heat back from the surface to which it has been applied instead of retaining or absorbing it.

When applied on a buildings interior, an Insuladd® Thermal Barrier will reflect heat back into the structure, and greatly reduce heat loss in winter, heat that would normally be lost to the cold outside air.

An Insuladd® Thermal Barrier not only provides for heat-energy reflectivity when added to paint, but also for heat-conduction insulating properties.

By applying a high heat reflecting ceramic paint to your buildings walls or roof, you reduce the heat before it even gets to your insulation. This reduces the heat load on your insulation making it far more efficient as it has less heat to deal with.

If your mass insulation was poorly installed or has deteriorated due to dampness or age, it is practically worthless. Insuladd® insulating ceramic paint products can be easily and inexpensively applied to walls, roofs and ceilings to create a thermal barrier which will maximize the energy efficiency of that home or building.

If not blocked by a radiant barrier, radiant energy will eventually pass through your insulation, and require supplementing to keep family or workers in the optimum 'comfort zone' (Non-comfort temperatures can significantly impact on health, fatgue, productivity etc. of family or staff).

Adding a heat reflector such as Insuladd® Thermal Barrier enhances the effectiveness of whatever R-Value you presently have in your home's walls and ceilings.

In the Winter when interior walls and ceilings absorb a great deal of the heat that you generate with your heating system, this heat will now be reflected and retained, and not flow outward through the walls and ceilings of your home, into the colder outside air. Your savings in heating related energy consumption will be significant!

In Summer the reverse applies. Extended air-conditioning running times can be reduced, resulting in big savings in cooling related energy consumption requirements.
Ceramic Coatings vs. Fiberglass Insulation The objective is not to 'rubbish' traditional mass insulation products, as they have for many years contributed to New Zealanders comfort.

Fibreglass is the giant in the insulation industry, and the R rating to which it conforms is ingrained in the minds of contractors, builders, and code inspectors.

Insulating ceramic coatings simply offers an alternative to traditional batt insulation.

Ceramic coatings have yet to become code-approved and accepted as a sole means of insulating a home, but the demand for increased energy efficiency is certainly pushing these products to the front of the consumer market.

Until the resistance to change is worked through and reflected in the coding regulations, Insuladd® will focus predominantly on the re-paint market.

We will continue to encourage people that are relying on generated energy to heat or cool their homes or work places to embrace the advancements made in insulating technology.

If the technology evolved by NASA during the space program is effectively reflecting heat build-up on the shuttle, this technology obviously has a lot of merits.
Every structure in New Zealand, whether a home or business, can reduce their consumption of energy by supplementing their outdated existing insulation with new technology Insuladd® paint on insulation.

Not only will significant cost savings be achieved by New Zealand energy consumers , but additionally the spin-off reductions in COemmissions and the use of non renewable natural resources in New Zealand will be significantly impacted.

The optimum time to apply an Insuladd® 'Radiant Barrier' coat is when you do your regular painting cycle (usually every 10 years). If one misses the opportunity to apply Insuladd® when painting, one misses the opportunity to benefit from 10 years of lower energy costs.
