R-Values of insulating materials are measured in laboratories and are designated a nominal R-Value per inch. In the wall or ceiling of a building most factory-made insulation materials suffer a reduction in performance due to air leakage and infiltration. The insulating value of many building components may be as low as 50% of the nominal R-Value of the insulation they contain.

In the wall or ceiling of a building, most factory made insulation materials suffer a reduction in performance due to air leakage and infiltration. The insulating value of many building components may be as low as 50% of the nominal R-Value of the insulation they contain. But, the insulation of a wall containing BioBased will perform closely to the laboratory tested R-Value of the material and seal the wall cavity from air infiltration as well.

We do not recommend that SEALECTION 500 be applied in existing walls. However, we have had good results in using SEALECTION 500 in the attic and in the crawl space (if applicable) without disturbing the walls in a retrofit application. The reason is that a large portion of your energy loss is caused by the "chimney effect" - hot air rises therefore creating air movement within a house.

Other blocks using inserts or hollow core blocks with poured insulation range between 5 and 6 for a 9 and 10" block.

The R-value (a measurement of the thermal efficiency of the door) for our ShowCase is 10.25. The R-value for our Decade II and our insulated Classic is 5.0. When considering thermal efficiency, also consider the weathersealing around the perimeter of the door and the amount of air infiltration between the door sections. The R-value is important, but it's only one part of your door's weathersealing system.

R-value is an assigned number derived from a specific testing procedure to determine a materials (or building assemblage) "resistance to conductive heat transfer". The higher the R-value, the more resistant a material (or building assemblage) is to conductive heat transfer.

The SEALECTION 500 spray foam is a complete insulation and air barrier system that insulates and air seals walls, floors and ceiling cavities against air movement, including spaces around electrical outlets, baseboards, and where the walls meet windows and doors etc. This means that outside air (hot or cold) cannot seep through walls causing drafts or cold spots. It also means that hot humid air cannot enter the walls and condense on cold surfaces causing molds, mildew and premature decay.

SEALECTION 500 Insulation has excellent sound absorption properties and sound transmission properties. When comparing SEALECTION 500 to other insulations, there is a very noteworthy difference. As an effective air seal, it eliminates the air gaps through which sound travels easiest. SEALECTION 500 Insulation is superior in controlling mid-range frequencies that include the most common sounds, the human voice and stereo music.

No, SEALECTION 500 is a "green" product. It meets off gassing requirements of CGSB 51.23 92 for new residential construction. No toxic or carcinogenic products were detected. No, SEALECTION 500 Insulation is stable. It does not shrink or sag. The reaction that created SEALECTION 500 Insulation is irreversible and it cannot break down into its constituent parts. SEALECTION 500 remains flexible throughout the life of the building.

The thermal performance of AAC is equivalent to R-20 insulation. AAC combines the advantages of low thermal conductivity and low air-infiltration with high thermal mass. This product is used in every climatic region of the world, from humid South America, to the dry heat of the Middle East and the severe cold of Finland. Insulation is rarely added; the walls are simply thicker. For more information on thermal performance testing, please see our Energy Efficient page.

SEALECTION 500 shall be installed on site by qualified installers trained in the proper safety and handling of the chemicals. Other trades persons should be kept away from the immediate area where spraying is conducted.

That's a good question, but unfortunately the answer is not so simple, Window thermal performance is measured as a U-Value which Is the reciprocal of the R-Value ( R-Value = 1/U-Value. For example. R 2 = U .50, or 1/.50 = 2) A bit of background: the R-Value measures the resistance to heat loss or gain, while the U-Value measures the transmittance of heat through a material. The higher the number in R-Value the better the resistance, so the better the insulating value.

No. Products with R-values reduce rates of "conductive" heat transfer and are tested for this characteristic. Radiant Barriers provide benefit by dramatically reducing "radiant" heat transfer which is just as quantifiable but not related to R-value type performance.

No. Our products do not operate in this manner. Minimal benefit is netted when the product is doubled.
