Go Green Smart with Vinyl

All of the windows and doors used by Quantum Windows and Doors are made of vinyl. Vinyl is a sustainable, environmentally friendly material that is designed to last. The less energy efficient building materials like wood may seem like a greener solution at first, but wood is much less energy efficient. Other materials are also known to break down much faster than their vinyl counterpart, which calls for them to be replaced more often. You must also consider the fact that vinyl products do not require any paint, stain, stripper, thinner, or other solvents that are harmful to the environment. Vinyl is completely recyclable as well.




All our Windows and Doors are 100% Canadian made using only the highest-grade of materials.


All our windows meet or exceed the CSA standards and Energy Star Criteria, and come with a written windows lifetime warranty.


Our professional and courteous installers are factory trained, certified, licensed and insured.


High-efficiency Windows and Doors

Saving energy and natural resources with high-efficiency Quantum Windows and Doors is the best way to make your home greener. At Quantum Windows and Doors green solutions begin long before our windows are installed in your home. Our entire company revolves around responsible purchasing and use of natural resources, from the materials we use to install our windows to the materials we recycle to be re-used in another installation. Quantum keeps their eyes open to make sure we minimize our carbon footprint and help to make our environment cleaner and more enjoyable.
