Your Vaughan Insulation & Fireproofing Contractor

Vaughan is builder country. Northstar works with several of the largest GTA homebuilders on new-construction spray foam packages in Kleinburg, Maple, and Patterson, plus retrofit attic work in mature Thornhill and Woodbridge.

New Vaughan homes are larger than average — 3,500–5,000 sq ft is common — which means more attic, more rim joist, and more cathedral ceiling to insulate. Our high-output rigs are sized for these jobs and we routinely complete a full new-build spray foam package in a single day.

Local building stock

Predominantly new-build executive homes, large estate properties in Kleinburg, plus mature 1980s Thornhill stock.

Vaughan tip

Large Vaughan homes with vaulted ceilings need closed-cell foam under the roof deck — fibreglass simply can't hit code R-value in 2x10 rafters.

Recent Vaughan project

Open- and closed-cell hybrid spray foam package on a 4,800 sq ft Kleinburg new build — full envelope, two days on site.
