The foil or paper facing is a vapor retarder. There is no difference in R-value between foil or paper faced batts. While the foil is a somewhat more effective vapor retarder, it is also more expensive and less widely available.

It is our opinion that this material is overrated, underperforming, and too expensive. There is no technical basis to claim an r-value more than 3 ? per inch. Radiantec products are compatible with these products, but Radiantec does not sell this special type of subflooring material. It is quite expensive. This subfloor heating method will put out more heat, but if the area does not need the extra heat, then the money is not well spent. It will not be more energy efficient. See similar questions...

Note: Freshly poured concrete gives off a significant quantity of moisture that is corrosive to facings containing aluminum foil or metallized film. See similar questions...

No. The foil on the fiberglass is in direct contact with the attic floor. Aluminum foil becomes more conductive when in contact with a solid surface. The air space facing the foil surface is of primary importance. See similar questions...

Greenhouse insulation surprises people, but.... A modern greenhouse in good condition can achieve average insulation but the majority of others can only be classed as poor. Surrounding walls are only a problem if they contain combustable materials (e.g. wood or drywall) or material that would melt (e.g. porch screening). See similar questions...

There are several key reasons cellulose insulation is a superior product for buildings: higher R-per-inch values than most comparable mineral fiber materials, reduces air-leakage, not as subject to convective heat loss, lower cost relative to competing products of similar thermal efficiency, fire safe, made from more than 75% recycled material, environmentally friendly, approved by all major code bodies, and well tested and field proven.

First, the NO-COAT® Structural Laminate Drywall Corner is not a corner bead. Paper faced metal corners and metal corner beads have a beaded nose, which requires a deep fill coat of joint compound to create the illusion of a flat surface. Instead, NO-COAT® corners utilize a unique structural laminate (SLAM™) design with a tapered co-polymer plastic center that eliminates the need for deep and repetitive coats.

It is essential that floors which are ground bearing or suspended over an un-heated space with or without underfloor heating are properly insulated to meet the U-values requirements as stated in the Building Regulations Part L1/L2 2002. The value is currently set at 0.25 W/m 2K. The thickness of insulation required to achieve this will vary according to the type of floor, size of floor and type of insulation selected.
