Batts
The most widely used insulation for residential construction in our region is an unfaced fiber glass batt. It is a flexible product, composed of small diameter glass fibers, with a resin binder. The majority of its thermal resistance is obtained from the trapped air pockets created by the matrix of spun fibers within the batt, not by the fibers.

Today’s generation of fiberglass batts do not settle, are non-combustible, resistant to moisture, mold, mildew and rodents. Batt insulation requires the use of a polyethylene air/vapour barrier on the inside for control of air and moisture movement. When properly installed within the building envelopes wood framing (i.e. 2” x 6”), fiber glass batts, combined with a well sealed air/vapour barrier will meet the standards developed by Energuide for a ‘typical new home’, up to an ‘energy efficient new home’. Typically, additional levels of thermal insulation must be added to obtain the ‘highly energy-efficient new house level’ or the ‘R2000 standard’.

- This product is pre-cut and packaged based on the stud width and spacing common to wood frame construction, for a friction fit insulation
- Individual packs are first labeled based on the R-value with R-12 & R-20 versions representing 2" x 4" and 2" x 6" framing respectively. Secondly, there are also packaged in 15", 19" and 23" widths and suit standard stud, joist and truss spacing (also produced in a range of other R-values up to the R40 batt - e.g. R28 version suitable to 2" x 8" framing). The final difference that will be noted is color, which varies solely based on the different manufacturers.
- CCMC approval listing is available form all major producers and often indicated in the package labeling
