Thinking of installing a folding sliding door system (bi-fold doors) to your home or business? For added warmth, security and weather resistance choose the slimline Aluminium Warm Core system.

This innovative, attractive, high quality system is both energy efficient and recyclable and is designed to eradicate draughts due to its triple-sealed structure. Fitted with precision rollers, beautifully designed handles and high quality mouldings, the doors offer a sleek appearance together with great strength. The system is security tested, with its robust structure, double-strength corners, integral dog-bolt and strong aluminium hinges giving you great peace of mind.

Constructed using stylish yet hardwearing brushed aluminium with a thermal core and 28mm double glazing, the door system has a U-value of 1.5 W/m²K. Upgrade to 44mm triple glazing and the U-value can be improved to 1.0 W/m²K, improving the thermal efficiency of your property.

We’re pleased to offer a choice of colour finishes including white, cream, black and grey, with the system available as traditional French or residential doors in addition to folding sliding doors.

Whatever you choose, you’ll be delighted with the appearance, durability and thermal efficiency of the Horsford Aluminium Warm Core.
