Quality
Through & Through.
Quantal is the only aluminium glazed roof system to hold the prestigious BBA accreditation — versatility of bespoke construction with the practicality of easy installation. Each configuration is engineered using specialist software so the spec exceeds wind and snow loads required for the property's postcode.
Postcode Engineered
NASA satellite data informs structural sizing for wind and snow loads. Every critical element — eaves, ridge, valleys, jack rafters — sized for the site.
Pre-Manufactured
As much of the structure as possible is built off-site — install times come down, accuracy goes up, and the on-site labour bill stays predictable.
Bi-Fold Ready
Integrated structural solutions for large spans of bi-folding doors — Quantal handles the load so you don't need a steel above the opening.
