Choosing the Right Insulation: A Simple Guide for Kingston Homebuilders and Contractors

If you’re building or renovating in Kingston, choosing the right insulation matters. Good insulation keeps your space warm in the winter, cool in the summer, and helps cut down on energy bills. But with so many options, it can be hard to know where to start.

At Ecocomfort, we’ve been helping homeowners and contractors across Kingston, Brockville, and Belleville since 2010. Here’s what you need to know to make the right choice for your project.

Spray Foam Insulation: Best for Full Performance

Perfect for: New builds, additions, full-home upgrades

Spray foam is one of the best options when you want serious energy savings and comfort. It expands to fill every gap, so it keeps out drafts, moisture, and even pests.

  • Creates an airtight seal
  • Reduces energy costs
  • Helps control moisture and air quality

It costs more upfront, but you’ll feel the difference year-round—and save money in the long run.

Rockwool Insulation: Solid, Safe and Soundproof

Perfect for: Basements, renovations, soundproofing projects

Rockwool, also called mineral wool, is a high-density insulation that resists fire and dampness while blocking out noise.

  • Excellent soundproofing
  • Naturally fire-resistant
  • Great for retrofits and shared walls

It’s not as airtight as spray foam, but it holds its shape well and performs reliably over time.

Fibreglass Insulation: Essential and Cost-Effective

Perfect for: Budget-conscious builds, attics, garages, and unfinished walls

Fibreglass insulation is one of the most widely used and affordable options out there. It’s lightweight, easy to install, and does a decent job at slowing down heat loss.

  • Lower upfront cost
  • Good thermal performance in basic applications
  • Non-combustible and moisture-resistant when installed properly

It’s a solid choice for simple projects or when budget is a top priority, though it doesn’t provide the same level of air sealing or moisture control as spray foam.
