Our Core Services

  • Batts & Poly: Sustainable, GREENGUARD-certified insulation for walls and ceilings. It resists moisture, won’t settle or lose its R-value over time, and installs easily.
  • Blow-In-Blanket System (BIBS): A more efficient alternative to traditional batts. Fiberglass is blown in behind a mesh fabric at a set density, so it fills gaps, voids, and seams and doesn’t settle. It’s also a good choice for soundproofing between floors.
  • Blow-In Loose Fill: Attic insulation for vented attic spaces that helps reduce your heating and cooling costs.
  • Spray Foam (2 lb Closed Cell): High-performance, environmentally friendly foam that works as an air and vapor barrier. It’s ideal for walls, rim joists, cantilevers, and non-vented attics.
  • DC315 Thermal Barrier: A protective thermal barrier applied over spray foam.
  • Monoglass: Thermal and sound insulation for concrete buildings, steel Q-decking, parkade ceilings, and Quonset huts. It can be tamped for a finished look or left natural.
  • Smoke Seal: Treatment for fire-damaged walls and surfaces.
