Energy Efficiency That Meets Today’s Standards
Building energy requirements across Canada have become more demanding, making proper insulation one of the most important factors in overall performance. AJ Design & Build installs spray foam, batt, blown-in, and specialty insulation for new construction, renovations, and retrofit projects across Canada. We help builders and homeowners achieve required R-values based on current building codes — whether it’s high-performance walls, upgraded attic insulation, or continuous insulation for commercial envelopes. Our team understands air sealing, vapour barrier placement, and thermal bridging, ensuring insulation performs effectively in real conditions.
The Right Insulation Type for Every Application
Selecting the correct insulation depends on the specific application and performance goals. Closed-cell spray foam provides high R-value per inch while acting as both an air and vapour barrier, making it ideal for tight spaces like basements and ceilings. Open-cell spray foam offers strong air sealing and sound control at a more economical cost, commonly used in interior applications. Fiberglass and mineral wool batts remain a cost-effective solution for standard wall cavities and attic spaces when installed properly. Blown-in insulation is ideal for filling irregular or existing cavities in retrofit projects. We install all major insulation types and guide clients in choosing the best option based on efficiency goals, budget, and structure design.
Insulation for New Builds, Renovations, and Specialty Projects
New construction projects benefit from proper insulation installation at the right stage — after framing and mechanical rough-ins, before drywall installation. Renovation projects require detailed evaluation of existing insulation, especially in older properties where materials may be outdated or insufficient. AJ Design & Build also handles specialized applications such as garden suites, soundproofing between units, and HVAC duct insulation for improved efficiency. With our combined services in framing and drywall, we manage the full process — ensuring insulation is properly installed, inspected, and ready before final wall finishing.
