Keeping Winnipeg Warm And Dry Since 1958

Insulation is essential everywhere—but it’s particularly important in Winnipeg with our cold winters and hot summers. Without proper moisture barriers, water can infiltrate insulation, degrading its R-value and causing water damage. 

The experts at STAR can help you choose the right insulation and moisture barrier for your project. There is no one best insulation; using a combination of different insulation products can help you reduce costs while achieving the right R-value for your project. 

Looking for an insulation product that we don’t have in stock? Get in contact with us; our team can custom order it for you from our suppliers. Thanks to our relationship with these manufacturers, we can source products quickly—and at excellent prices.
