A NRG Block is six to ten times higher in R-Value than a common block, which ranges from 1.5 to 2.5 depending upon the aggregate used.

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

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. See similar questions...

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. See similar questions...

The R-value is the measure of the resistance of a material to heat flow (or heat gain) by conduction only. The k-value is the measure of thermal conductivity; it measures the rate of heat transfer by conduction through a material from face to face. ASTEC's thermal conductivity (k-value) is very low (0.00345 W/m ?K or 0.00199 Btu/h ft ?F). A very low k-value indicates a good conductive insulator. See similar questions...

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

R Value - the measurement of 'insulating ability' of the material. The higher the R Factor number the greater the insulation value. U Value - the measurement of 'heat loss' through the material. The lower the U Value the less heat is escaping. See similar questions...

R-value is a standardized measurement of thermal efficiency. The higher the R-value, the greater the insulating properties. Overhead Door manufactures insulated doors with a broad range of R-values designed to meet your needs. Our Thermacore® doors offer our highest R-values - up to 17.5. See similar questions...

When cured, the concrete in AMVIC walls is 50% stronger and use 30% less concrete than traditionally poured walls. While the cost of a bare block or poured wall is less, AMVIC provides insulation and furring strips, and is ready to finish, making it a cost effective and less labor-intensive choice. AMVIC also is far less labor intensive to use where there are frequent openings and/or popouts as are frequently the case in residential construction. See similar questions...

The R-Value is formulated using an inch of thickness as a measure. Due to the fact that Nansulate is made to go on in a thin layer - less than an inch thick - an accurate R-Value cannot be calculated for it. Nansulate works by acting as a barrier to heat transfer. It does not only insulate by trapping air, as other insulations do. Nansulate’s effectiveness can be seen in this energy savings demonstration, which shows how it can effectively insulate and slow down heat transfer. See similar questions...

NRG Blocks can be made in all types of architectural finishes including split face, smooth face, marble face polished and weathered face finishes. See similar questions...

No, quite the opposite. The R-value for Premier Series glass block is 1.96 - more than twice the R-value for flat, single-pane glazing (THINLINE™ Series glass blocks have slightly lower R-values of 1.75). You can add the benefits of increased protection from solar heat gain with LX FIBROUS GLASS INSERTS. Remember, this degree of insulation comes to you without the maintenance and upkeep demands of your conventional windows. See similar questions...

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. See similar questions...
