How does spray foam control vapour in a new build?

Closed-cell spray foam acts as both insulation and a vapour control layer once it reaches the specified thickness. Our team applies it to the depth your assembly calls for.

Where do new homes lose the most air?

Common leakage points include rim joists, top and bottom plates, around windows, and at service penetrations. We target these areas during installation.

Can you combine different insulation types on one project?

Yes. We often pair spray foam at sealing points with batt insulation across wall cavities to match performance goals and budget.

New construction insulation in London

Enerliv Insulation works closely with builders and contractors on new construction projects across London, Ontario and surrounding areas. With cold, snowy winters and hot, humid summers, proper insulation is essential to maintaining year-round comfort while controlling energy costs in Southwestern Ontario homes and commercial buildings.

Our certified installers handle insulation from the framing stage, ensuring your project meets Ontario Building Code requirements while staying on schedule. By insulating early in the construction process, we help create an airtight, energy-efficient structure that performs well in both extreme winter temperatures and summer humidity. Partner with Enerliv Insulation for reliable, code-compliant insulation on your next build in London. Contact our team today to discuss your project’s needs.

Spray Foam Insulation

Closed-cell spray foam seals gaps and adds an air barrier in one step. It suits rim joists, exterior walls, and below-grade areas where moisture and air leakage are a concern on a new build.

Batt and Poly Insulation

Batt insulation with a poly vapour barrier is a dependable choice for interior walls and ceilings. It keeps material costs predictable on larger residential and commercial projects.

Combination Insulation

Some new builds benefit from a combination approach, with spray foam at key sealing points and batt insulation across open wall cavities. This balances air-sealing performance with budget.

Projects We Support

We support a full range of new construction projects across the region. That includes custom home building and new residential construction, along with new commercial developments and new industrial builds. Whatever the scale, our team scopes the insulation to suit the assembly and the timeline.

Residential Insulation (New Builds)

Well-installed insulation keeps indoor temperatures steady through Ontario winters and summers, and it lowers heating and cooling costs for the homeowner. It also reduces sound transfer between rooms and creates an air barrier that supports indoor air quality, so a new home feels comfortable from day one.

Our Insulation Process

Our process begins with an assessment of your building plans and site conditions. From there we move to material selection, recommending the right products for each assembly. Our certified team installs to code, and we finish with a final inspection to check coverage and air sealing before close-up.
