Centra Windows (Formerly Supreme Windows Inc.)

Recognizing the significant potential for growth in Alberta, Centra Windows acquired Supreme Windows Calgary earlier this year. This made Centra the largest window installation company in all of Western Canada. We've improved home comfort and increased energy efficiency for countless people across Alberta and BC, and we can do the same for you.

Products designed for Calgary
 Centra windows are designed to help regulate your home’s temperature by keeping it cooler in the summer and warmer in the winter. This will result in lowered heating and cooling costs in the months where the weather becomes extreme. The Centra Windows team are Calgary locals, who can help you choose a window or door package that works for your home and suits your style.
 We love Calgary. Centra Windows utilizes only top quality window and door components and we produce our products at our manufacturing plant in Calgary. The end result is windows and doors which are perfectly suited to Calgary’s variable climate and conditions. When combined with our quality installation standards and highly trained team of installers, it is no wonder that we have such an outstanding reputation in the Calgary marketplace.
