Slim, Strong, and Stylish

Our bi-folding doors are crafted from robust aluminium profiles, providing slim, aesthetically pleasing sightlines without compromising on strength or durability. This makes them a perfect “fit-for-purpose” solution for folding sliding doors, combining modern design with long-lasting performance for any Glasgow home.

Energy efficient

Our aluminium bi-folding doors feature a large polyamide thermal break within the profiles, preventing cold transfer and keeping your living space warm. With a standard 28mm double-glazed unit, these doors exceed building control U-value requirements.

For even greater efficiency, we offer 36mm triple-glazed units, further reducing heat loss and improving energy performance. Additional options include self-cleaning glass and double-glazed units with integral Venetian blinds, providing ultimate privacy, light control, and convenience.

Solar Control as Standard

All our bi-folding doors come fitted with Planitherm 4 Seasons glass as standard. This advanced glazing provides superior thermal insulation, reducing heat loss more effectively than traditional low-E glass. Its built-in solar control element helps maintain a comfortable indoor environment all year round, keeping your home warm in winter and cool in summer.
