Premium Accoya® Option

15 Year Accoya Guarantee – Timber Box Sash Window

Accoya® is the industry’s leading timber regarding durability. Due to Acetylation the Timbers Cell structure is altered making the wood far less water absorptive. After Acetylation the Timber is kiln dried further almost charring the wood to a golden brown. Ultimately any changes the wood could have gone through naturally whilst in the elements has already happened. We are making more and more Accoya® Windows and the industries confidence is growing strongly. After 80 Years research Accoya® claim the wood is good above ground for 50 Years and 30 Years Submerged.

This option allows our customers to upgrade their windows to be made entirely from Accoya® Timber.

PERFORMANCE KEY BENEFITS

Paint Options

As Standard all Joinery is supplied with End Grain Preservative and Primed & Undercoated with 2X Coats of Mighton/Teknos Brand – Sealer Primer.

 

We paint by spray application in our own custom-built spray booth. Spraying as opposed to brush application means we avoid leaving brush marks on the timber and whilst less cost-effective covers much more evenly. People are often shocked our windows are made from timber as the paintjob is left flawless.

However, we understand customers want windows with minimum maintenance and work for other trades once installed. We offer to fully paint finish windows, so our customers don’t have to. The service includes a further rub down between coats and spray applied 2x Further coats of Mighton/Teknos Brand – Micro-porous Topcoat in any RAL Colour. The finish we achieve is superb as we prepare each type of timber for spray application. What’s more we select timbers that take well to painting and the results speak for themselves. All that is left for our customers is some general decoration i.e. to Fine Finish any patch plastering and match in the Room Colour. Book a Visit to our Workshop to see for yourself.

Draft Proofing

 

All of our Sash Window and Door ranges comes fully Draught Proofed and Sealed. They have a perimeter brush pile polypropylene stripping, discreetly contained within concealed carriers installed at the edges of our sashes and contained hidden behind the Parting Bead & Staff Beads, maximising thermal heat retention and sound insulation. The benefits of installing brush pile into our sashes means that you won’t see any brush and after time the brush can build up dirt but is a vital component of the window. Hiding them in this design means that regardless of what configuration the sashes are in you won’t see any dirty brush.

The Double or Quadruple Sash Stile Brush

If your budget permits ask for us to incorporate Double or Quadruple brush into your sashes. This does add more work to the manufacturing process, however improves the glide and draft proofing capabilities of your sash windows.

The biggest comment we hear from our customers is that their home feels more solid and quieter since they had their new sash windows fitted. We love hearing this kind of feedback and whatever your brush number of choice this draft proof brush will reduce noise, draft and stop sash rattle. (Some sash stiles may only have room to accommodate Double Brush)
