At Westbury, we source sustainable, premium grade timber for all our windows
Manufactured using a combination of laminated modified Accoya® and European sourced timber including European Redwood, our windows are knot-free and bonded to provide superior quality, strength, and stability that solid wood cannot come close to matching.
The elements most vulnerable to the weather, such as cill extensions, are manufactured from solid Accoya®, giving outstanding durability and stability due to its water-resistant properties.
Vulnerable sections are laminated to provide excellent stability and a superior finish. Durable materials are always placed on the outer exposed layers.
These premium timbers have extremely low thermal conductivity, coupled with specially formulated bonds and strong joints, this ensures the highest standard of finish.
Independently tested to current British and European Standards
Westbury products are independently tested by a third party UKAS accredited test centre to current British and European Standards. Windows and doors are tested in accordance with BS 6375 Part 1: 2009 “Performance of Windows & Doors, Classification and Guidance for Weather Tightness”
Westbury Weather Gasket
Casement windows and doors feature continuous double layers of weather seals in high performance TPE (thermoplastic elastomer) material. This is a superior “soft close” seal combining optimal sealing and insulation with a comfortable closing pressure.
The following summarises the results of testing carried out to classification standard listed.
Air Permeability to BS EN 1026 : 2000 BS EN 12207:2000
Water Tightness to BS EN 1027 : 2000 BS EN 12208:2000
Wind Resistance to BS EN 12211 : 2000 BS EN 12210:2000
Part Q Compliant
Westbury products are independently tested by a third party UKAS accredited test centre to current British and European Standards.

The Weighted Sound Reduction Index (Rw) is a number used to rate the effectiveness of a soundproofing system or material. Increasing the Rw by one translates to a reduction of approximately 1 decibel in noise level. Therefore, the higher the Rw number, the better a sound insulator it will be.
The following test results demonstrate the sound reduction index of various Westbury products in accordance with BS EN ISO 10140-2:2010. Each result is followed in brackets by an adjustment (C,Ctr) These are figures you deduct for an accurate reduction index of pink noise (C) and Traffic noise (Ctr).
Paint – it’s more than just a splash of colour
The paint that coats our timber windows is of vital importance. The technology that goes into modern paints means that when applied correctly, these will add years to windows and doors.
Water-based, microporous, flexible paint systems are made up of water and plastic. After application the water evaporates, leaving a highly durable and protective plastic layer behind. As a result, our customers don’t need to regularly sand down their windows and doors, then prime and paint and repeat.
Westbury’s timber customers need only apply a new coat of paint every 10 years. Even then, the product only requires just one simple coat of paint.
Paint technology when applied correctly gives your product longevity, the aesthetic you’re looking for, and a saving on both money and the time you won’t have to spend maintaining it.
