WarmCore Folding Sliding Doors

WarmCore is an innovative aluminium folding sliding door system which incorporates a radically different product design approach to deliver a new high performance fenestration framing solution: “warm aluminium”. At Synseal, we are redefining thermal performance in wide span aluminium doors.

Built around a belief that beauty doesn’t have to compromise performance, WarmCore aluminium folding sliding doors were created out of a desire to combine the desirability and durability of aluminium with unparallelled insulation. The orange thermal core – hidden away in the finished doors – is key to why WarmCore doors are 25% more thermally efficient than traditional aluminium systems.

“Built with a revolutionary thermal core at its heart…”

Strong and secure, WarmCore doors come with class leading security built in, backed by a comprehensive 10 year product guarantee, reinforced by the ERA Five Star security guarantee. Inwards or outwards
opening doors up to 6m wide, with as many as 7 opening sashes glide along custom designed tracks. While a wealth of colour, style and configuration options help you choose the perfect warm, secure and beautiful WarmCore door for your home.
