Wooden Windows and Doors

Double glazed Oak or Accoya® Doors and Windows:

We make high quality, double glazed timber windows and doors for our timber frames but we will also take orders for bespoke, individually designed doors and windows which we make using the highest prime joinery quality seasoned oak, or Accoya® .

Types of timber:

-Seasoned Prime Joinery quality Oak: The English Oak (quercus Robur) produces an incredibly tough durable timber which possesses a timeless beauty. Our bespoke oak windows and doors will enhance any property, old or new. We use 21st century technology to make our bespoke oak windows and the combination of the aesthetic appeal of seasoned oak, together with modern warm edge spacer bars, energy efficient Planitherm glass technology, and high security multi point locking systems deliver high performing windows which also look great!

-Accoya® wood is a high performance wood. Created from sustainably-sourced wood, Accoya® undergoes a proprietary, acetylation process that permanently modifies the wood to the core. The result is an environmentally friendly solid wood with a durability and dimensional stability that matches or exceeds even the best tropical hardwoods.


Types of Window:


-Traditional Flush Casement Windows: The traditional flush casement window has an un-imposing simplicity and looks great in seasoned oak. We use heavy duty stainless steel butt hinges as standard, and locking fasteners and casement stays. The design of the window profile and the quality of the modern glass and seals means that these traditional windows look good in period properties and contemporary homes and deliver great energy efficiency.

- Stormproof Windows: Stormproof windows are a modern variation of the flush casement window and allow the opening window to slightly overlap when closed to ensure a totally weathertight fit. These windows are fitted with friction hinges and as espag locking system.

- Heritage Traditional Flush Casement Windows: The profile and the moulding of these double glazed windows was designed to suit the houses and farmhouses of the Mount Edgecumbe Estate properties which are numerous throughout West Devon and East Cornwall, but their attractive traditional profile would be suitable in many situations in which heritage conservation grade windows are required.

Our windows are supplied as standard with 4/16/4 (24mm) Pilkington K argon gas filled double glazed units with a U value of 1.2, with warm edge spacers.

Paint & Stains:

Teknos microporous paints and stains: We have a factory spray painting facility for a professional paint or stain finish to our doors and windows. We use the Teknos range of water based microporous paints and stains which are designed
to protect and decorate a wide range of exterior and interior joinery to ensure superior durability.
Teknos paints and stains are available in an almost unlimited range of opaque and translucent colour . To see the wide range of finishes available, please visit the Teknos UK website : or ask us for a Teknos brochure.
