Where is insulation installed

In addition to walls and attics, insulation should be installed in ceilings with unheated spaces, basement walls, floors above vented crawl spaces, cathedral ceilings, floors over unheated garages or porches, knee walls, and in between interior walls—especially bathrooms—as well as ceilings and floors. But, not every area is easily accessed.

Ceilings and attics are always good places to start, both because they are accessible and because more heat escapes through the roof than any other part of the home. The most common products for attics and flat ceilings are R and R fiberglass or mineral wool batts. This is to assure that the insulation fills the spaces between the ceiling joists or bottom chords of trusses and also extends above and closes over most wood members.

To achieve R-values of R and higher, two layers can be used and their R-value combined. For example, an R batt added to an R will yield an R Fiberglass or mineral wool loose-fill insulation can also be used.

The insulation can be installed to any R-value. However, to achieve the correct R-value it is extremely important that the proper amount and minimum thickness of insulation be installed.

A combination of batts and loose-fill insulation is another alternative. Because high-performance batts achieve the same R-value as standard insulation — and are not as thick — they need not be compressed to fit the angles and spaces typically found in cathedral ceilings.

Tom Silva replies: Filling walls with a fluffy layer of fiberglass insulation is one of the easiest and least expensive ways to make your home more energy efficient. All it takes is a utility knife, a straightedge, and a little patience to make sure the insulation completely fills the stud cavity, side to side and top to bottom, without being overly compressed.

Fiberglass is easy to cut, so if your stud spacing is irregular, buy batts that will fill the widest bays, and trim the rest to fit. When you're ready to begin, protect your skin, eyes, and lungs by wearing a long-sleeve shirt, pants, gloves, safety glasses, and dust mask. First, the Thermano panels should be fixed to the wall.

The fixing is only needed for the sake of panel stabilisation. The wall must be flat enough so that the Thermano panels adhere to it thoroughly with their entire surface. The panels can be attached using polyurethane glue or mechanical connectors. In the case of the construction presented here, plastic connectors were used.

The next stage of work involves securing all the joints between panels with aluminium tape. This will ensure appropriate tightness of the system.

As an additional protection, a vapour breathing membrane may, but does not have to, be used. The strips are mounted vertically, usually at a distance of cm from one another. The strips are fixed to the structural wall with long screws.
