100% Silicone White Roof Coating is a premium, moisture-cure coating designed to reflect the sun’s heat and UV rays as well as protect many types of roofs. While suitable for use in all climates, the 100% silicone chemistry is especially suited for extreme tropical environments, which are exposed to some of the hottest and wettest weather with intense UV exposure. It is specially designed to maintain maximum reflectivity of heat and UV rays as it ages. Its moisture-cure chemistry creates a very aggressive chemical bond with the roof, which provides permanent ponding water resistance, extreme durability, and superior capabilities of sealing and protection.
Acrylic polymers can be formulated to be tough and hard, and also very flexible. Plexiglas impact resistance is one example where it is used in banks to provide bulletproof shields. But acrylic polymers can also be manufactured to be flexible, to be tolerant of movement at low temperature, very elastic in their behavior.
Our acrylic polymers have been engineered that are specifically designed for roof applications. Acrylic elastomeric roof coatings are a seamless, fully adjered, elastomeric membrane. They provide durable weatherproofing and are much more resistant than traditional roofing to general chemical attack from precipitation and vent emissions.
Assuming your roof is not in such a poor condition that the only option is replacement, covering your existing roof with a new spray roof coating membrane offers many advantages.
- They can be applied to virtually any new or existing roofing surface to create a seamless membrane that protects against permanent ponding water, ultraviolet light and severe weather.
- It’s permanent and will not degrade, chalk or crack under harsh UV rays.
- It creates a smooth surface that offers excellent resistance to mold, mildew and staining.
- Reduces energy costs over a standard roof replacement by reflecting heat.
- Less expensive than costly tear off and roof replacements.
The two main choices are fiberglass and cellulose, and each has its advantages and disadvantages. They both insulate about the same, though, with R-vales in the 3 to 4 per inch range.
Fiberglass comes from a ‘rapidly renewable’ resource – sand. It’s basically made up of tiny glass fibers. Usually fiberglass insulation is covered with something after it’s installed, or it’s installed in an area where it won’t be disturbed (such as an attic), so the fibers won’t get into the air where they could be inhaled. With these precautions, it’s no threat to your health.
Cellulose is manufactured primarily from recycled newspapers, a very benign product, so it poses virtually no ongoing health risk. It is coated with chemicals that make it safe and fire-retardant.
Spray foam insulation provides a healthier, draft-free, indoor environment. Because expands to fill every cavity, crevasse and void, it provides a sealed thermal envelope that does not sag or settle over time. This improves indoor air quality by blocking harmful outside irritants such as mold, pollen and other allergens and offers an alternative to fibrous particulates which are attributed to many traditional insulation products.
Spray foam insulation is so effective because it is applied as a liquid and expand 100 times the original liquid size in seconds. As it expands, it conforms and fills each cavity, crevasse and void to create a sealed thermal envelope. It creates a highly-efficient seal against air infiltration, the number one source of energy loss in any structure. This innovative insulation adheres to any clean, dry surface and will not sag, settle or disintegrate. Advanced Seal spray foam insulation’s also are an inert substance and will not support mold growth, insects or rodents. It also does not breakdown over time, so it creates a sealed interior that blocks harmful outside irritants. Here are some of the key advantages:
- Completely fill and seal every crack– polyurethane spray foam’s expansion properties allow it to expand up to 100 times its original size to completely fill every crack in walls, ceilings, and crawlspaces for total insulation and air sealing.
- Spray foam stays in place– spray foam insulation does not shrink, settle or sag over time ensuring total continual performance.
- Reduce allergens– spray foam’s air sealing qualities help reduce the amount of dust, allergens, and pollutants entering your home. It even prevents mold or bacteria growth, thanks to its water resistance.
- Reduce energy loss and waste– spray foam will reduce heating and cooling costs by up to 50%.
- Won’t attract insects or rodents– polyurethane spray foam does not provide a source of food for rodents, termites, etc. the material also doesn’t make good nests.
- Moisture control – Just one inch of closed-cell spray foam creates a barrier moisture cannot flow through.
- Sound barrier – Spray foam insulation is a superior sound barrier to either batt or blown in insulation.
- Higher R Value – Spray Foam insulation has a higher R Value per inch than either batt or blown in insulation.
- Added building strength – Because of its rigid nature and ability to adhere to many materials, closed-cell SPF can provide structural enhancement to framed buildings.
The initial investment of spray foam insulation is a bit higher than that of batt or blown insulation. However, the benefits of spray foam far exceed any other insulation choice today. In fact, you will find that spray foam insulation gives you a much higher return on investment by saving between 30-50% on your annual energy costs. Spray foam insulation will help your heating and air conditioning system to work more efficiently.
Since spray foam insulation helps regulate your temperature throughout your entire home or building, your HVAC temperature will not drop or rise dramatically every time it’s turned on/off. Your initial investment in spray foam insulation pays you back over time in energy savings.
In addition, spray foam insulation is a stronger noise barrier, is not effected by wind or water, adds structural strength to wood-frame structures, and will not shrink or settle over time.
Yes. Spray foam has more density than fiberglass and its physical properties attenuate sound more effectively.
Because of its rigid nature and ability to adhere to many materials, closed-cell SPF (ccSPF) can provide structural enhancement to framed buildings. Racking strength of certain framed walls, as well as uplift strength of framed roof decks can be significantly increased with the addition of just 2-3 inches of SPF.
There are two basic types of spray foam insulation. These are referred to most commonly as Open Cell and Closed Cell Spray foam. They each provide certain benefits and differ in characteristics and uses. Both open-cell and closed-cell foams stop the movement of air and slow down the transfer of heat. The tables below are a brief review of the two types.
Closed-Cell Foam: This is the more common type of spray foam between the two. Denser than open-cell foam, it reduces humidity and features better resistance to water. It prevents the growth of bacteria and mold, which can compromise structural integrity.
Open-Cell Foam: While its application is the same with closed-cell spray foam, its effects are different. Because it expands to fill the cavity, it covers hard to reach areas that closed-cell spray foam can’t. This, however, is less common because it doesn’t provide water resistance and is more pervious to vapor.
As it is currently used, R-value is a number that is supposed to indicate a material’s ability to resist heat loss. It is derived by taking the k-value of a product and dividing it into the number one. The k-value is the actual measurement of heat transferred through a specific material.
The test used to produce the k-value is an ASTM (American Society for Testing and Materials) test. This ASTM test was designed by a committee to give us measurement values that – they hoped – would be meaningful. Unfortunately, the test was designed with a flaw or bias. The test was designed with input primarily from the manufacturers of fiber insulation products like fiberglass, rock wool and cellulose fiber and the like. Very little input went into the test for solid insulations, such as expanded polystyrene or urethane foam because these products were adopted as building insulation products several years later.
Thus, in order to enable their products to achieve high scores, the fiber insulation manufacturers lobbied heavily to have the test exclude air movement (wind) or any amount of moisture (water vapor). And therefore fiberglass is generally assigned an R-value of approximately 3.5 per inch. However, it will only achieve that R-value if tested in an absolute zero wind and zero moisture environments.
Zero wind and zero moisture are not real-world. Our buildings leak air, all our buildings leak air, and they often leak water. Water vapor from the atmosphere, showers, cooking, breathing, etc. constantly moves back and forth through the building envelope. If an attic is not properly insulated, water vapor from inside will very quickly semi-saturate the fiber insulation above the ceilings. Even small amounts of moisture will cause a dramatic drop in fiber insulation’s R-value — as much as 50% or more.
Spray foam insulation is not subject to those problems. One and a quarter inch of polyurethane sprayed properly in the wall of a house will prevent more heat loss than all the fiber insulation that can be crammed in the walls — even up to an eight-inch thickness. Not only does the polyurethane provide better insulation, it provides building with significant additional strength.
Water, wind, and other conditions present in our atmosphere barely affect the performance of solid insulations like spray foam. This is why spray foam with an R-value of 6 will perform about 50% better than fiberglass or cellulose with an R-value of 13.
Bottom line, spray foam insulation is overall better than any other form of building insulation.
