BALSAM-WOOL Standard Building Insulation is a flexible insulating blanket made from pure wood fibers in fleecy wool form, permanently matted together be tween two sheets of asphalt-coated, tough, flexible, creped Kraft paper. These pat ented crepe paper liners are capable of
25 per cent stretch which makes them virtually puncture proof, and the fact that these liners are not stitched renders BALSAM-WOOL windproof and water proof. In the process of manufacture, BALSAM-WOOL is chemically treated to make it fire resistant, vermin and rot proof. It is clean, odorless and sanitary--
a Weyerhaeuser product.
Sizes---BALSAM-WOOL for building
insulation comes in three standard widths,
17, 25 and 33 in. and in two standard
thicknesses,
and full inch. It comes
rolled, wrapped and sealed. l/z in.
BALSAM-WOOL weighs 240 lb. per 1,000 sq. ft., and full inch BALSAMWOOL weighs 370 lb. per 1,000 sq. ft.
Application--In frame construction, BALSAM-WOOL 17 and 25 in. wide is

applied between the studding, joists or roof rafters, flanged in the air space be tween sheathing and plaster. BALSAMWOOL 33 in. wide is applied to the inside face of the studding or joists with furred out lath and plaster. In solid masonry construction, 17 or 25 in. BALSAMWOOL is applied by flanging between fur ring strips 16 or 24 in. on center. 33 in. BALSAM-WOOL is applied with either single or double furring strips.
Efficiency--BALSAM-WOOL has been tested for insulating efficiency in various laboratories throughout the country. In a building insulated with BALSAM-WOOL. 20, to 35 per cent less radiation and boiler capacity is required. The coefficients given on the next page are recommended for us'i in computing the heat loss through sections insulated with BALSAM-WOOL. A com plete file showing coefficients and the method of computing radiation require ments and fuel saving (A.I.A. File No. 37-b) will be mailed on request.
