Fiberglass Replacement Windows Windsor Ontario
Lakeshore Windows And Doors - Fiberglass Windows
Maintenance Free Fiberglass Windows cost more than vinyl windows but are on par with high quality wood / clad windows. Factoring in the maintenance free life and long term energy efficiency, fiberglass windows have one of the lowest lifetime cost of any frame material.
Other than Metal (a major conductor or heat & cold), fiberglass is the strongest frame material. This allows for a narrow frame profile which in turn allows more glass area to provide a better outdoor view, and more natural light inside.
Because fiberglass frames and glass are made from the same material (silica sand) the reaction to outdoor temperature is almost identical. This makes the entire window system and weather stripping more airtight. Internal stresses are reduced because the whole window works as one unit.
We at Lakeshore Windows and Doors are so proud to be Southern Ontario's only authorized dealer of the Marvin Infinity and Integrity fiberglass windows. These windows are fashioned after traditional wood windows. Most fiberglass windows on the market look just like a vinyl window - not ours. Marvin is North America's #1 selling fiberglass window.
