How does one insulate a cantilever that is always cold?

What is a cantilever?

A cantilever is a residential extension that sticks out from one side of the house, and that is not supported by beams or posts. This additional structure can be used as a balcony or as a separate room and is commonly used to extend a small home. However, this addition comes with specific challenges regarding residential insulation, considering that a cantilever extension is located outside the structure.

How to ensure the proper insulation of a cantilever

A recurrent problem we see is that cantilevers are often insulated with wool, an unsuitable material for this type of structure. Our experts believe that a good practice would be to remove the existing insulation and add a 7’’ layer of polyurethane, a much more efficient material for this specific structure.

It is best to deal with experts for cantilever insulation, to avoid unpleasant surprises such as an improper installation, which would make the floors of the cantilever cold. Whether you have an insulation project in Laval or Montreal, trust our experts to do the work for you. Our professionals combine years of experience in the insulation of cantilevers.

Can one insulate outside with polyurethane?

For example, it can be installed on the outer face of foundation walls or under a concrete floor, where the floor slab is not fulfilling a structural function.

Is condensation a problem that can be solved by adding cellulose?

Most of the time, a condensation problem is due to poor ventilation in the attic.
Installing styrovents before adding cellulose will play a key role in reducing the humidity in your home as much as possible. Installing a ceiling fan is also recommended, as is clearing soffits if they are blocked.
