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.

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.

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 derived from a controlled laboratory test of insulation’s resistance to conductive heat flow. BioBased 501 has an R-value of 3.83/inch.

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 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.

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.

This is a measurement of heat resistance (the higher the number, the better). R value = the number 1 divided by the U value.

The importance of basement insulation depends on whether the basement is heated. If you heat your basement, or if your furnace or other sources of heat are in the basement, you should insulate the basement walls to contain the heat. If not, you should insulate the basement ceiling to reduce heat loss to the basement and keep your floors warmer.
