A Dry Home for Health & Longevity

Prioritizing Occupant Health

At Elite Airtight Envelopes, we prioritize the health of both your home’s occupants and the structure itself. Modern homes are particularly vulnerable to moisture-related issues, such as mold and rot, which can have a detrimental impact on both health and longevity.

Our comprehensive insulation and building envelope solutions effectively manage moisture, preventing water intrusion and the growth of harmful mold spores.

By creating a dry and healthy living environment, we ensure the well-being of your home and those who reside in it.

Protecting Your Investment

Enhancing Durability

We understand that durability is a key factor in the long-term value of your home. Uncontrolled moisture can lead to decay, corrosion, and structural damage, compromising the overall integrity of the building.

Our meticulous insulation and building envelope techniques provide an extra layer of defense against moisture-related issues.

By effectively managing water infiltration, we protect your investment and increase the durability of your structure. With our comprehensive solutions, you can have confidence in the long-lasting quality and resilience of your home.

We take pride in our quality of work and believe that your investment needs the best insulation to ensure your comfort and decrease your heating and cooling bills.

Roof & Ceiling Assemblies

Detailed with batt insulation and air/vapour barriers with the highest attention to detail since these are sensitive areas that need to be especially as air-tight as possible. Alternately, spray foam can be used to create an unvented assembly here if desired and allowed by the district.

Wood-Frame Walls

Rockwool or fibreglass insulations typically fill voids in exterior walls and are completed with meticulously detailed vapour-control layers and air-barriers. We are experts at achieving a “Grade 1 Energy Star Installs” which means the thermal layers are installed with very little voids, gaps, or unnecessary compression. Spray foam is sometimes used here as well.

Concrete Walls

Rigid insulation and/or batt insulations and air/vapour barriers are often used in combination to achieve a well-sealed exterior foundation without problems with condensation and wet wall assemblies common in the past. Spray foam can also be used here.
