Aluminium Bi-Fold Doors
Built around a belief that beauty doesn’t have to compromise performance, aluminium folding sliding doors were created to combine the desirability and durability of aluminium with unparalleled insulation. The orange thermal core - hidden away in the finished doors - is essential to why doors are 25% more thermally efficient than traditional aluminium systems. Built WITH A REVOLUTIONARY thermal core at its heart
Solid and secure, doors have 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 seven opening sashes glide along custom-designed tracks. At the same time, a wealth of colour, style and configuration options help you choose the perfect warm, secure and beautiful door for your home.
The beautiful, solid, secure door is 25% more thermally efficient than the competition!
The warmer choice that saves you money
The traditional weakness of aluminium doors has been the aluminium itself. While a beautifully strong and hard-wearing material, aluminium is a good conductor of energy. The warmth from your home finds an easy path outside, leaving you colder and with higher heating bills. Most aluminium folding sliding doors try to overcome this inherent weakness by replacing a section of aluminium with a small thermal break of less conductive material to lessen this heat loss.
From Sheerline, this revolutionary folding sliding door was designed to be as thermally efficient as possible. Built around a full-width thermal core - maximising the use of low conductive material - keeping heat in your home than traditional aluminium doors. Yet, it doesn’t compromise strength as the outer faces of the profile are high-grade aluminium positioned to add the most significant structural rigidity.
TRIPLE GLAZING - THE BEST THERMAL PERFORMANCE BI-FOLD
Robustly designed to take the weight of triple-glazed panes as standard.
Choose this option on your Bi-folds for the best thermal-performing doors currently available.
At least 75% better than a standard Bi-fold door with an impressive U-value of 1.0
High performance, easy clean glass Celsius Clear insulated glass is an optional upgrade on folding sliding doors.
This unique high-performance glass utilises a Low-E and solar control coating, with an Argon-filled cavity, to limit the amount of UV and heat that passes through the glazed unit, giving the ultimate in thermal control, whatever the weather.
