Types of Insulation The R-values of plastic fiber insulation vary with the batt’s density, ranging from R-3.8 per inch at 1.0 lb/ft 3 density to R-4.3 per inch at 3.0 lb/ft 3 density. Plastic fiber insulation is relatively non-irritating to work with, but the batts reportedly can be difficult to handle and cut with standard tools.

How to Estimate How Much Batt Insulation Is Needed for Walls Include height if you're estimating batt insulation that is cut to length. Keep each required batt size separate. Divide the total square footage for each insulation size by the square footage supplied in a package in of insulation to determine the number of insulation bundles needed to insulate the walls of your home.

The R Value Myth Nevertheless we have Code bodies mandating R-values of 20s or 30s or 40s. But a fiber insulation with an R-value of 25 placed in an improperly sealed house will allow wind to blow through it as if there were no insulation. Maybe the R-value is accurate when the material is lab tested.

Adding Attic Insulation In a cooling climate, a good blanket of attic insulation helps keep the house cooler and reduces the load on air-conditioning equipment. Most attics are insulated with blown-in loose cellulose (R-3.5 per inch), blown-in loose fiberglass (R-2.5 per inch) or fiberglass batts (R-3.2 per inch). Cellulose is recycled newsprint treated with a fire retardant. Fiberglass is just that--thin fibers of glass that trap air.

How to Make Your Home Energy Efficient Current building codes recommend an insulation R-factor of R-38 for attics in most of the country. That would be about 10 to 12 inches of fiberglass batting or blown cellulose fiber insulation. Bear in mind that R-38 is actually the minimum recommended standard for attic insulation.Proposed energy codes would increase that number to R-50.urrent building codes recommend an insulation R-factor of R-38 for attics in most of the country.

- In cold climates, a vapor retarder on the insulation's inside face prevents conden-sation that robs R-value and encourages mold. Batts faced with paper or foil have the retarder built in. Unfaced batts should be covered with 6-mil plastic or MemBrain (shown), a breathable sheet. Apply a bead of sealant to the top plate and to any studs where the sheets overlap, then tack the sheet every 12 to 24 inches to the top plate, studs, and bottom plate.

- Check the insulation in your attic, ceilings, exterior and basement walls, floors and crawl spaces to see if it meets the levels recommended for your area. Insulation is measured in R-values—the higher the R-value, the better your walls and roofs will resist the transfer of heat.

- Insulation R-value is only valid in still air. If you have a breeze going through your attic from soffit or roof vents it will degrade the R-value of exposed fiberglass insulation. The best results are gained by decking over the insulation, using a sheet product over exposed fiberglass insulation, or sealing up the attic completely and using a foam product under the roof deck to make the attic an enclosed space.

- The R-value (a measure of effectiveness as an insulator) of ICFs is typically rated R-18 to R-35, depending on the thickness of the wall. In comparison, 2x4 wood framed walls are usually rated R-10 to R-12; 2 x 6 wood framed walls are rated around R-19.

Info-512: Crawlspace Insulation The best insulations to use are foam based and should allow the foundation wall assembly to dry inwards. The foam insulation layer should generally be vapor semi impermeable (greater than 0.1 perm), vapor semi permeable (greater than 1.0 perm) or vapor permeable (greater than 10 perm) (Lstiburek, 2004).

- The energy savings is accounted for by two factors – the thicker wall enables wall insulation to be upgraded from R-13 to R-19 and less studs mean less thermal bridging. Building scientists suggest that builders should consider the “whole-wall” R-value as opposed to the center-of-cavity or rated R-value of the insulation.
