Window frames are vital parts that substantially influence the thermal performance and weather protection of any window or door installation. When frames are not accurately fitted, they become a significant source to heat escape and which in turn result in homeowners throughout the St Catherines area to face higher energy bills.
Our UPVC Window frames use thoughtfully engineered multi-chambered interiors within their framework. This intelligent design establishes an effective barrier, blocking chilly outside air from coming in while simultaneously retaining the important heat generated within your home.
This superior heat retention significantly reduces your risk of excessive energy costs. Without proper insulation, the heat your heating system creates would quickly be lost, forcing your system to run constantly and resulting in inflated energy bills.

When fitting 6.0 and 3.0 rated glass, the low thermal rating causes substantial heat to be lost, resulting in outer glass surfaces that are moisture-free and see-through even during cold spells or icy situations.
