FIBERGLASS BATTS

Fiberglass is a thermal insulation  used in the construction or retrofit of a building. The materials are used to reduce heat transfer by conduction, radiation and convection, and are employed in varying combinations to achieve the desire outcome. If installed properly this insulation can be effective, energy efficient and long lasting.


Fiberglass batts are one of the most traditional forms of insulation. It is important that you put the right thickness of insulation in the cavities you are filling.


Fiberglass batt insulation can be pink, yellow, white or green, depending on its manufacturer and has a spongy feel. Commonly found in blanket form, it is available in bags containing standard pre-cut lengths and widths. Fiberglass batt insulation is designed to fit between joistsm rafters or studs without leaving gaps.


Fiberglass batt insulation used to come with a paper vapour barrier attached to one side. It would fit between the joists and had a reinforced paper edge for stapling the batts in to place. Todaym the standard fiberglass batts are slightly wider than the space between the walls studs or ceiling joists and are in stalled by friction-fit. When combined with a properly installed vapour barrier, sealed with accoustical caulking and sheathing tape, it is an efficient and economical way to stop air infiltration and heat transfer.


When fiberglass is compressed, its ability to insulate is diminished greatly.
