Why Solarlux bifold doors?

Fully Manufactured in Germany
They are constructed whole in Germany, complete with frame, doors, glazing and ironmongery, ready-hung for installation. Each door is custom-made to your size and requirements.

High Performance
Solarlux doors are precision engineered to a class-leading standard. They are independently tested to 1200PA (approximately 100 mph) and remain water-tight beyond that. The SL80 has been tested to failure at 3000Pa (a typical tropical hurricane is about 2400Pa).

Thermal Insulation
All Solarlux doors are thermally broken on the whole system, including the threshold. The class-leading U-values are provided on the whole unit, not just the door panels, so that you know exactly what you are getting. U-values range from 1.4 for the standard SL60e with double glazing down to 0.79 for the SL79 with triple glazing (subject to specification).

Security
Solarlux take security very seriously, and all models are tested to the rigourous European RC2 standard. The SL60 and SL80 also have Secure by Design, a British standard created by the Association of Chief Police Officers.

Warranty
Some manufacturers require evidence of a rigorous maintenance regime to qualify for warranty. Spectrum provide a no-quibble Solarlux-backed warranty. As one of the elite Solarlux 'Active Partners', we are also able to offer an enhanced warranty.

Durability
You expect your bifold doors to slide effortlessly from the day one. But you also want them to be equally effortless 10 years later. The stresses on a bifold door are considerable — and only doors engineered to such a high standard will last the distance. Solarlux doors are tested to 20,000 cycles — the equivalent to opening twice a day, every day for 27 years!

Passive House
The Solarlux SL97 has a U-value down to 0.79 and meets the standard for Passive House installations.
