Aside
from door and window glass, insufficient insulation is one of the main
sources of heat loss in homes.
Fibreglass batt
insulation is the most used thermal insulation material in home construction.
It's sold in rolls or in batts designed to fit in 16- or 24-in. spaces.
As a general rule, the space between wall studs is 16 in., while the space
between ceiling joists is 24 in. For walls, install fibreglass batts from
inside the house, against the sheathing - which is covered on the outside
with an air barrier and an exterior siding. In the attic, insulatation
is laid flat between the ceiling joists. |

Installing a vapour
barrier Moisture
problems such as rot and mould can be avoided with the proper installation
of a vapour barrier. What happens in the winter, the air in a house has
a higher rate of moisture than the outside air and the moisture inside
the building seeks to escape. To prevent this water vapour from creating
condensation in the envelope of the building, promoting rot and mould
problems and eventually structural damage.
