Looking for the best in new construction windows? You've found them! Mitten is proud to bring Ply Gem's industry leading line of new construction windows to Sherbrooke contractors and developers. 

While windows are a frequent target for upgrade and renovation projects, there is something to be said for getting them done right the first time! New construction windows are specialized for buildings still in the process of construction, designed to be securely nailed directly to the frame and studs, offering the highest level of construction quality and security. 

Ply Gem's windows come in a variety of styles and designs while maintaining the highest manufacturing standards in the industry. Designed to exceed performance expectations, you can count on greater energy-efficiency, enhanced UV blockage, and noise dampening properties when compared to competitors across every price point in Ply Gem's line, making them a strong long-term investment for new homeowners and contractors alike.

Why stop at windows? Mitten also offers:

  • Mitten's leading line of premier vinyl siding products
  • Realistic stone veneer, shake, and accent pieces
  • Aluminum Soffit, Fascia, Rainware & Accessories
  • Accents and accessories, including blocks, rails, and decorative columns
  • A wide range of building insulation products and sealants
