Why choose Smarts aluminium windows and doors
Smarts aluminium windows and doors combine slim profiles that maximise glass area with minimal mullions and transoms, creating a light, modern feel without overpowering traditional architecture. Every product is powder-coated for durability and weather resistance, resistant to warping, corrosion and fading, with a long lifespan and low maintenance compared to timber alternatives.
The range spans Alitherm 300 windows and 1000 Series bifold doors, the Heritage 47 range with its Art Deco-inspired steel-look profiles, and Visofold commercial doors, available in a wide choice of RAL colours, from cream and anthracite to matt black, to suit both contemporary and traditional homes across Colchester, Essex and Suffolk.
Slim sightlines
Slim profiles, maximum light.
One of the standout features of Smarts aluminium windows and doors is how the glazing frames the view, slim profiles maximise glass area, with minimal mullions and transoms for an uninterrupted, light-filled result.
