| Which
Insulation choose? |
|
| Polyurethane
foam |
Composed
of renewable vegetable oils, soybeans and 40% of recycled plastic
bottles, polyurethane foam insulation is the most effective and
most performing that exists on the market. Its
performance is superior to any other insulation product. Unlike
other products, polyurethane will remain stable, does not collapse,
will not settle and does not crumble. |
| Benefits: |
- Excellent adhesion to most building materials;
- Excellent air and vapor barrier;
- Has the highest thermal resistance;
- Eliminates air infiltration and heat loss;
- Weatherproof and mildewproof;
- Flexible and quick to install.
|
| Where
is it needed? |
- The concrete surfaces such as foundation walls in the basement;
- Can be sprayed on the exterior and interior walls of the house (brick, wood or concrete);
- For maximum efficiency, it is sometimes used in the attic;
- It is the product of choice for insulating joists banks
(More commonly known as belt, caps or smooth);
- For insulating cathedral roofs;
- We also use it, for maximum efficiency, on all forms of roof (flat and slope);
- Crawl space (also known as cellar of service).

| Polyurethane
and fire: |
|
Polyurethane
is not flammable. However, when it is exposed to flame, it releases
toxic gases that can interfere with the evacuation of occupants
during a fire.
That
is why the National Building Code requires that the product is
coated with an approved flame retardant product that will retard
flame for at least 20 minutes (Firestopping). This requirement
excludes all crawl spaces not accessible by a staircase. The National
Building Code Volume 1, paragraph 3.2.2.9 clarifies when a crawl
space should be considered a basement.
|
| What
if your basement is insulated with polyurethane? |
- It should be covered with a suitable material and / or approved
|
| What
are these materials? |
- The wallboard (drywall)
- Prefinished panels
- Wood
|
|
| Cementitious
firewall Monokote Type Z-3306 (registered product) |
| Cement-based
compound, the Monokote Type Z-3306 forms a thermal barrier ensuring
sustainable and durable protection against heat and fire. It can
be painted .* |
|
| Fibrous
firewall (registered product) |
| Used
as a thermal barrier, the application of this fireproof insulation
is rapid and economical.* |
| This
product can be applied immediately after sprayed polyurethane. |
|
| Blown
or injected cellulose |
| Injected
or blown cellulose fiber is made from recycled newsprint and biodegradable
components. |
| Benefits: |
- Provides excellent soundproofing for its superior ability to absorb sound;
- Saves 30 to 50% on cost of heating and air conditioning;
- Does not pollute or irritate and is not toxic;
- Excellent resistance to fire;
- No risk of corrosion.
|
| Where
is it needed? |
- For the insulation of the inner roof also called attic (blown cellulose)
- For the insulation of walls, ceilings and floors (injected cellulose)
|
|
| Stabilized
cellulose |
| Benefits: |
- Has the same advantages as blown and injected cellulose;
- Its uniqueness is that it contains a product (a kind of glue)
which adheres it to the walls where it is injected;
- Does not sag.
|
| Where
is it needed? |
- It is injected into the walls for insulation and soundproofing;
- Used especially in the walls of houses located near a highway.
|
|
| Mineral
Wool |
| Wool
mat is made of fiberglass. It is available in mat and can also be
blown. However, cellulose increasingly replaces blown wool. |
| Benefits: |
- Economical choice;
- No mold or parasite can resist this product;
- Includes thermal and acoustic properties.
|
| Where
is it needed? |
- On the walls facing the outside of houses;
- The cathedral type ceilings;
- In the attic.
|
|
| However,
it must be properly installed to provide maximum efficiency. |
