Why it sells
Features Your Customers Will Notice
Slim 50mm interlock
Where the panels meet, just 50mm of aluminium — more glass, less frame, and the contemporary look customers want.
Large panel capability
Aluna handles big panels, so wide openings need fewer of them — cleaner lines and easier handling on site.
Effortless sliding
Quality running gear keeps even large panels gliding smoothly with minimal effort.
Thermal performance
Thermally broken aluminium profiles with high-performance glazing keep the extension comfortable year-round.
Secure by design
Multi-point locking and robust aluminium construction give solid security on ground-floor elevations.
Colour flexibility
Popular greys and blacks plus a wide RAL range, with dual colour available inside and out.
