Insulation Types
Insulating materials are given an insulating "R" value which quantifies their level of insulating effectiveness. These materials varies widely. The types of insulation used in modern homes are blankets and batts of fibreglass and rock-wool, fibreglass board, rigid foam boards etc.
Fibreglass and Rock-Wool Blankets and Batts
The majority of all home insulation is fibreglass and rock-wool blankets and batts. They are made of fibres that are compressed in a roll form like a blanket or in short rolls (batts). Blankets and batts come in many thicknesses and widths, and with or without vapour barrier material on one side.
Another form fibreglass and rock wool have is shredded, or blown by machine to its place. Even though loose insulation (blown by machine) is cheaper to purchase and install, it will lose some of its insulating value.
Fibreglass and rock wool insulation have excellent insulation values and are among the most economical types to purchase.
Foam Insulation
Given equal R-values, foam delivers about 20% to 40% better overall performance than traditional fiberglass or cellulose insulation.
Spray foam isn't
a bad product, however, it is easy to botch by an inexperienced installer.
Fiberglass or rock wool products are more fool proof to install.
The biggest issue with spray foam from a sustainability standpoint is
that it is made of toxic chemicals, some of which will pollute the indoor
air long after owners take occupancy of the home.
Once applied to the substrate, spray foam insulation is very
difficult to remove.
Rigid Boards
Rigid foam is used for basement walls, exterior walls, concrete slabs etc. rigid boards are manufactured in a variety of materials such as, polystyrene rigid boards, fibreglass boards, and rigid foam boards.
Let us assist you in installing insulation either as part of a renovation or replacement or as a new build.
