Over 50 years of expertise
From manufacture to installation, Lorimer windows are made to measure for your home and backed by 54 years of experience.
Double glazed windows in Scotland
Lorimer windows are manufactured at our Scottish factory and designed specifically to perform in Scotland’s changing weather conditions. Whether you’re replacing ageing windows or renovating your forever home, our bespoke double-glazed windows combine exceptional thermal efficiency, advanced security and beautifully slim frames that maximise natural light.
What is double glazing?
Double glazed windows are made with two panes of glass sealed to create a unit that is fitted within a frame.
The panes are joined together by a warm edge spacer bar, and the gap between them is flooded with insulating argon gas to help reduce heat loss and improve energy efficiency.
- Double glazing helps keep warm air in and cold air out
- Low-Emissivity glass reflects heat back into your room
- Our units feature 95% argon gas-filled cavities – improving thermal performance and reducing heat loss
- The Lorimer multi-chambered uPVC profile improves insulation and structural rigidity
- We double-seal glazed units for increased thermal performance
- High-performance weatherstripping and gaskets prevent draughts and water ingress
