Roof Insulation: Make Your Home Weather Resistant
The main purpose of roof insulation is to provide weather resistance, an
important requirement for homes as it protects them from the dangers of humidity
and extreme temperature conditions. Roof insulation products are usually
available from insulation contractors and suppliers.
Materials
Asbestos was previously used for roof insulation. However, asbestos is no longer
in use due to its harmful properties, and other materials have taken its place,
including rock wool, glass wool, sheep wool, cellulose and polyester. Most roof
insulation materials made from synthetic mineral fibers and foam insulation are
also used on a roof's underside. Roof insulation materials are usually available
in batt, blanket or loose-fill form, and may either be installed from the
outside or inside of the house.
Methods
The homeowner and the insulation contractor usually decide on roof insulation
placement. If placed on the exterior, reflective foil will be used. If placed on
the underside of a roof, it is installed through the house's interior. Take note
that some obstacles to this method might include electrical wiring, vents and
other fixtures. As a solution for this, spray foam insulation may be used. Some
types of spray foam insulation applied to the underside of the roof binds the
tiles and slates to create an effective weatherproof barrier against rain, wind,
snow and dust.
Some Precautions
Some general precautionary measures should be taken during the installation of
roof insulation, as it involves chemicals and other materials that could cause
skin or health problems. Professional contractors or engineers hired to do the
job are usually equipped with masks, gloves and appropriate protective gear, so
it is highly recommended for anyone not involved with the actual installation to
stay away from the work area.
The area should also be thoroughly cleaned with a vacuum cleaner to remove
surface dust, while at the same time checking if there is adequate ventilation
to maintain air quality inside in the house. In addition, there is always the
possibility of loose-fill or inferior types of insulation going through exhaust
fans, ceiling vents or even light fixtures, so the insulation should be of
superior quality. |
