TECHNOLOGY Sheerframe 8000

Sheerframe multi-chambered means a five chamber, fully reinforced, totally sustainable, organic stabilised, A-rated, zero carbon window. The BRE (Building Research Establishment) has independently assessed the life expectancy of PVC-U profile to be at least 35 years and that’s what you can expect with Sheerframe.
Sheerframe takes super high-performance windows up to code level 6 of the Code for Sustainable Homes. Sheerframe HED, (Homogenous Energy Dynamics), is the UK’s first zero carbon home compliant PVC-U casement window system. They also meet the requirements of Secured by Design and benefit from the PAS24 Security Kitemark. There is no better system for your home!
Thermlock Reinforcement - Sheerframe also benefits from the revolutionary Thermlock® - patented technology. This provides greater strength, better window security and improved thermal efficiency than traditional reinforcing. This means Sheerframe windows are fully reinforced and exceptionally strong, providing unbeatable security. Importantly, all our products are manufactured using lead-free, calcium organic stabilised technology.
