Duotherm single and double hinged doors

For many years Smarts have supplied the industry with Duotherm profiles market and for many years we’ve manufactured the Duotherm range of doors (and windows) for projects where people have required the benefits of strong slim aluminium profiles outside and warm contoured PVC-U profiles on the inside – the best of both worlds!

We’ve often found Duotherm to be the ideal solution for people who love the look and proportions of a traditional moulded timber door but are put off by the maintenance and performance issues that go with wood.

• Duotherm composite aluminium/ PVC-U hinged doors are the perfect complement to the Duotherm window suite. 70mm frames can be easily coupled with either structural Duotherm couplers making all door/fixed light/window combinations possible. Therefore with a full range of corner posts, couplers and mullions Duotherm frames are ideal for producing the vertical walling elements of a conservatory. Contact for further details.
• Duotherm is ideal for dual colour applications where white internal finish is required. The external aluminium profiles can be painted any standard RAL and British Standard paint finish as well as being available in silver anodised finish.

The Duotherm ‘Elite’range of main profiles feature full ovolo mouldings typically found on traditional timber windows and with a 70mm frame depth are an ideal replacement for softwood or hardwood doors.

Duotherm doors and windows are also available in either light oak or full mahogany woodgrain finish either both sides of profiles or woodgrain out / white PVC-U in.
