We choose to sell Ostaco windows because we feel they are the best.
Most of us want maintenance-free windows on the exterior of our home because let's face it-scraping and painting windows is no fun. Ostaco's Corewood windows offer the performance of a premium vinyl window with the beauty of wood for the interior of your home. Your choice of wood can be clear pine, cherry, oak or even a custom wood.
Ostaco Corewood windows are CSA approved and Energy Star Rated for the ultimate in energy efficiency. Choose from 3 levels of super efficient argon gas filled options to suit your objectives and budget. The vinyl can be colour matched too.
An added feature we really love is the Preserve Window Guard on every window. This prevents damage and scratches during installation- no more annoying labels to remove! After installation simply peel away the protective film on the glass for a perfect finish!
