UPVC Windows
Our UPVC windows combine modern design with thermal efficiency, featuring Liniar's multi-chambered profiles that trap warm air and reduce heat loss. Available in casement, flush sash, and tilt-and-turn styles, they achieve A+ energy ratings. Each window is made-to-measure to fit your property's aesthetic and functional needs.
Residential Doors
Liniar UPVC residential doors offer security and thermal performance, with composite options combining timber, uPVC, and GRP. Available in white, cream, and woodgrain finishes, they enhance curb appeal while maintaining energy efficiency. Our doors are PAS 24 accredited for enhanced security.
Conservatories
We design and install Victorian, Edwardian, and lean-to conservatories that maximise natural light and living space. Featuring thermal twin-walled top caps, they retain heat efficiently. Our conservatories are built to blend seamlessly with your home's architecture while offering year-round usability.
Replacement Roofs
SupaLite tiled roofs transform conservatories into insulated, weatherproof extensions. The lightweight aluminium frame and humidity-proof insulation reduce noise and temperature fluctuations. Customisable tiles ensure a seamless match with your existing property design.

Report
Been waiting 3 weeks for someone to phone me back. Not impressed. Had a window and door fitted and asked for a cat flap to be fitted to the door and some new handles to be replaced on some older windows, that information was not passed on to the fitting team, . They done the cat flap but not the handles.
Had to call them back as had problems with both the cat flap and the window, I must say that this was done over 2 years ago. We have now got trouble locking the door and draughts coming from the brick work and the pvc. Also we were not given any paperwork on completion of the job . I phoned over
