Lift & Slide Patio Doors

ptiwood Lift & Slide Patio Doors complement our range of high performance windows and doors, and are made from Scandinavian pine with multiple finishing and security specification options ensuring that every set meets the most exacting standards of manufacture, security, practicality and of course, style.

Construction

All timber used in the manufacture of Optiwood is harvested from well managed forests. Allan Bros are proud to only use softwood that is FSC® Certified Timber. We scan the wood to identify any imperfections by cutting out and finger jointing leaving you with a flawless finish. This superior timber is complemented by our state of the art production facility, and of course our 200 year history in manufacturing the highest quality timber windows and doors.

Finish

Because we manufacture windows and doors for every project ranging from period renovations right through to ultra-modern contemporary developments, we have developed an advanced range of specialist coatings to give you the exact finish you require, while ensuring superb weather resistance. You can choose from over 1,000 paint colours, including most RAL and BS4800 mixes, and a wide range of translucent wood stains.
