Secret Benefits of uPVC Sash Windows

The shift towards uPVC in the heritage market is driven by a number of essential benefits that resolve the historic defects of the sliding sash style.

1. Extraordinary Thermal Efficiency

Standard sash windows are well-known for being breezy and cold. Modern uPVC sash windows use multi-chambered profiles that trap air, serving as an insulating barrier. When coupled with high-performance double or triple glazing, these windows can accomplish an “A” energy ranking, significantly lowering heating bills and carbon footprints.

2. Boosted Security

Nevertheless, the innovation has advanced so significantly that many “Heritage Collections” of uPVC sash windows are now authorized for usage in conservation locations.

The key to approval is the “authenticity” of the window. If the windows include woodgrain textures, mechanical joints, and standard percentages, they are typically viewed as an appropriate option that protects the character of the streetscape while improving the building’s energy performance.
