What We Use & Why
Our material selection is driven by performance, code compliance, and lifetime durability.
← Tap a tab above to switch specs →
High-density polyurethane foam from manufacturers like Huntsman and BASF.
Custom depth applied on-site to ensure a seamless monolithic seal with zero gaps.
Certified R-value of 6.0-7.0 per inch, far exceeding standard fiberglass performance.
Fully certified for use in Canadian construction and 100% code-compliant.
Exterior walls are the primary defense against Ontario's wind and cold. 3.5 inches of 2lb closed-cell foam fills the stud cavity completely, eliminating the 'air gaps' found in standard batt insulation. This prevents convection loops and stops heat from leaching through your framing via thermal bridging.
Technical Depth: Insane Benefits of Sprayfoam
Understanding the physics of high-performance insulation helps you make the right choice.
Standard fiberglass batts provide zero structural benefit. In contrast, 2lb closed-cell spray foam is a rigid, dense material that actually bonds building components together.
Tests have shown that walls filled with 2lb spray foam can have up to 300% to 400% more racking strength than uninsulated walls. It acts as a structural glue for your framing.
This is critical for Markham properties facing high wind loads or older heritage homes needing structural stabilization.
Markham’s Spray Foam Evolution: From Heritage to High-Performance
Unionville Heritage Restorations
Restoring a double-brick home in Unionville requires modern Spray Foam Insulation performance without losing historic character. We apply closed-cell foam directly to the interior masonry, providing a high R-value in a thin profile. This creates an airtight vapor barrier that protects the historic structure while slashing energy costs by up to 50%.Angus Glen Custom Estates
Large-scale estates in Angus Glen and Cachet often feature expansive cathedral ceilings and complex architectural joints. We specialize in high-performance unvented roof assemblies, sealing the roof deck directly to eliminate ice dams and ensure total climate control in every room.The Science of the 'Air Seal'
Markham's biggest energy enemy is air leakage. Wind physically blows through electrical outlets and rim joists in poorly sealed homes. Our spray foam expands to fill these voids, creating a monolithic pressure-vessel that ensures your HVAC system works at peak efficiency year-round.

Because Markham is north of the city, homes are exposed to higher wind speeds. Air sealing with spray foam stops 'convection'—the physical movement of cold air into your home—which accounts for 40% of heat loss in most Markham properties.
Yes. We use 1/2lb open-cell foam between floors and partition walls to absorb noise, providing privacy for extended families living under one roof.
Absolutely. Our closed-cell foam is the ideal choice for older masonry because it provides a vapor barrier and R-value in a thin profile, protecting the brick from moisture damage while maximizing interior space.
