Synseal WarmCore is an aluminium bi-fold door system which uses “warm aluminium” technology to offer superior thermal performance over traditional aluminium bi-fold doors.
Astraseal manufactures Synseal bi-fold doors and supplies to UK trade. WarmCore doors are engineered to be easy to install and can be used to satisfy market demand for high performance slim-line aluminium bi-folds.
Superior thermal performance and weatherproofing
WarmCore’s unique concealed multi-chambered thermally efficient core offers superior thermal performance, which exceeds current and future Building Regulations.
Low U values of 1.4W/m2K are achieved with double glazing, and a U value of 1.0W/m2K with triple glazing. Door leaves are triple-sealed with weatherstrip gaskets to prevent the ingress of air and water.
Custom hardware prevents intrusion
The multi-chambered construction of WarmCore’s thermal core adds to the structural integrity of the door, improving its strength and security.
Synseal bi-fold doors also incorporate custom designed hardware designed to prevent intrusion and comes with an ERA “Five-Star” guarantee for up to ten years.

Astraseal manufactures and supplies WarmCore aluminium bi-fold doors on short lead times to the trade. Doors are available in four colour finishes from stock – White, Cream, Black and Grey.
