Insulation problems?

We are the best placed to answer to your needs.

Attic insulation

Most of the time, the attic is the most efficient place to add insulation. Normaly, an entrepreneur sprays an isulating material between and over the ceiling joists.

The air barrier installed on the ceiling needs to be waterproof to make sure that the heat and moisture of the house don’t get to the attic, where it’s colder, and can’t cause condensation during winter. Look up for air leaks up to the ceilings, to the top part of inside walls an to the opening og passage, like ventilation columns.

The adding of insulation must not block the soffits ; it might be necessary to put baffles.

Insulating your house

Even if anterior generations were accommodated to poorly insulated houses, most of people, today, prefer to live in warm and comfy houses. Today, a healthy house need to be airtight, well insulated and well ventilated.

Insulating your house is just like choosing the good clothes according to the climate. A wool sweater will keep you warm… as long as it’s not raining and wind isn’t blowing too hard ! For those windy and rainy days, we need to cover our woolen cloth with a waterproof nylon jacket so we can stay warm and dry. It’s just the same principle for your house! On it’s exterior envelope, right under the bricks or the siding, we find an air barrier playing the same role as the nylon jacket : preventing the wind to cross the walls.

Then comes the insulating (your sweather) and the vapour barrier. This last one keeps the moisture out of the structure, where it could cause serious dammages.

Insulating your basement by the inside

The walls of your basement are uniques : they need to stand in the way of a lot of moisture movements coming from the inside as much as from the outside of your house.

Sprayed polyurethane insulation is stiff and doesn’t rot. It keeps it’s insulating caracteristics for life. Adherent to its support, it doesn’t get packed up and doesn’t degrade over time, unlike mineral insulating. Applying polyurethane by projection allows a perfectly tirtight and waterproof insulation. Suppressing the thermal bridges by its continuous insulation, which contributes to greats energy expenses savings.
