The History of Alstar Insulators

Alstar Insulators opened it's doors in 1972 with a small office in Oxford, Nova Scotia and has been making homes warmer, more comfortable, and more efficient since that day. We have been working across Nova Scotia for the past 45 years, and are proud to say that we are among the most trusted insulators in Atlantic Canada.

Throughout the years, Alstar Insulators has expanded to offer a much wider range of Building Performance Services, such as the installation of Windows, Doors, and Siding, Draft Proofing, Mold Barrier Installation, Drain Water Heat Recovery System Installation, a full Suite of Renovation Services, and much more. We are also now working with a licensed Mini-Split Heat Pump Installer to supplement your home heating source to help save you even more all year long.

Our roots are in blown-in cellulose insulation, and while that is still a large focus of what we do - we also offer the professional installation of Icynene Spray Foam in both open- and closed-cell form that provides an air seal as well as a high R-value in walls, basements, and attic spaces.
