These replacement windows are available in numerous different styles and shapes, which can be configured into hundreds of different window combinations. Aluminum clad wood windows are traditionally known for requiring little external maintenance while instantly establishing a particular style. Vinyl replacement windows, tend to out-perform wood and Aluminum clad wood windows in several ways, such as being highly weather, rot, impact, fire, and corrosion resistant. They also tend to insulate well against noise, ideal for a city like Calgary.

Our most popular vinyl windows have an exciting feature available for customers that want window replacements.

James Hardie siding, a fiber cement product made from silica sand, cement and wood pulp, is highly recommended for the Calgary and area siding markets. Calgary, being geographically situated in hail alley, is prone to receiving sometimes devastating hail storms that cause excessive damage to siding, roofing and windows on residential homes. Hardie Board siding is extremely durable and is resistant to hail damage, (unlike vinyl siding that will crack and actually break), is insect resistant and is also non-combustible. In this regard it is superior to vinyl siding in Calgary and area. This product has become extremely popular with Calgarians that wish to avoid having their siding replaced each time a hail storm passes through their community.
