This means at least 6 inches of batt, blanket or loose-fit). insulation, and an effective vapor baKrier on the lower (warm) side of the insulation. The extra cost of a good insulation job will more than pay for itself over the life of the house. Your walls are the second most important source of heat loss. Aim for a total wall resistance of' R14 or more. This means an R factor for the insulation of at least 12, about as much as can be achieved with batts or blankets and 4-inch wall studs, Retrofit. Unfortunately, re- insulating walls is more difficult and more expensive than ceilings. You do have a number of options, however, depending upon the type of wall construction, existing insulation and money to spend. (a> Wall renovation (frame walls). If your plans permit extensive renovation, remove the wallboard or plaster and re-insulate the wall as you would a new one (see instructions below). Then replace the wallboard. While you're at it, you might want to attach 1 x 2" or 2 x 2" strips to the stud edges to allow for more insulation in the wall cavity. (b) Inside insulation (frame or masonry walls.) To avoid the trouble of removing the inside surface of a wall, or when this can't be done as with masonry walls, you can apply new insulation (batts, blankets or .rigidRanels) to the inside surface. Apply straps to the wall to attach the insulation and covering wallboard. (Remember the styrofoam should be covered by plaster or gypsum board.) You can use 1 x 2" furring strips for thin styrofoam; use at least 2 x 2" strips for batts, blankets or thicker foam. Once your strips are in place, apply the insulation according to the instructions below for frame walls. (c) Blown-in insulation (frame Walls). If you have hollow, or 'almost hollow, wood-frame walls you can have a professional insulation contractor blow in loose- fill insulation. He can do this from the outside if small sections of the ' exterior can be removed, as with clapboard. If the exterior is brick, aluminum siding or stucco, he'll have to drill holes in the interior walls and repair them when he's finished. Care must be taken that the entire stud space is filled — that no projectionS or cross- braces hinder the filling. process. (d) Foamed-in-place insulation. The cavity in older wood-f ra ne houses and in some masonry walls can, be filled with a foamed-in- pla.ce insulation, such as urea-formaldehyde. This must be done by a professional. Check the prices in your area and pick the contractor carefully. — New walls. When you're insulating new walls, the idea is to put in as much insulation as the stud space will accept. For extra* insulating value, consider 6-inch studs or a layer of styrofoam sheeting on the outside (under the exterior surface). Follow the instructions below. When you start to work on a wall that has peen framed, push blankets into the stud spaces so they touch the sheathing or siding. Work from the top down and place the staples about 12 inches apart, pulling down the flanges so that they fit snugly against the top and bottom .plates. If you're using friction fit batts or blankets without an attached vapor barrier, first wedge them into place, then cover the inside face of the wall with a suitable vapor barrier such as polyethylene, stapled to top and bottom plates. Unroll the sheet across the entire wall area, including window and door openings. You can cut these out later,. Be sure to fit insulation behind ,pipes, ducts' and electrical boxes. Pack space with loose insulation or cut a piece, to the proper size and fit it into place. Stuff pieces "of insulation between rough framing and dOor and window heads, jambs and sills. Staple vapor-barrier paper or polyethylene to cover these small areas. If you have non- standard-width studs or joist spaces, cut the insulation • and vapor barrier an inch or so wider than the space to be filled. Staple uncut flanges as usual. Pull the vapor barrier on the cut side to the other stud, fitting the insulation behind it, and staple through the vapor barrier to the stud. Unfaced blankets are cut slightly oversize and wedged into place.
