Our Accreditations

Accreditations aren’t just important for providing peace of mind, they’re also crucial for complying with relevant building regulations, especially on commercial projects.

All our windows are fully tested and accredited to the highest standards achievable with sash windows. Wherever possible, we also go above and beyond the documented standards. Not only does this ensure full compliance and guaranteed performance, it helps elevate industry standards to new levels.
