Finishing

All our windows are spray finished in our own spraying facilities. Our 4 spray booths factory apply 4 coats of exterior micro-porous paint. An under-coat and primer and two top coats in our standard white, to RAL 9016.

Our team of sanders and sprayers have years of experience in the preparation and application of all sorts of paint finishes onto our windows.

We can paint match any colour from well-known paint manufacturers like Farrow & Ball and The Little Green Paint Company and often are asked to dual finish windows with different colours applied to the internal and external faces.

Energy Efficiency

Timber windows are a good choice for improving the energy efficiency of a home, and can have several benefits.

• Our double glazed engineered softwood sliding sash box frame windows have been tested and certificated by the British wood working Federation BWF to have a U Value of 1.2 W/m2K.

• Our double glazed engineered softwood casement windows have been tested and certificated by the British wood working Federation BWF to have a U Value of 1.3 W/m2K.

• Our standard double glazed units tested in our windows were manufactured as follows: 4mm low iron glass /8mm Krypton filled spacer / 4mm Climaguard LowE CGA.

• Low-e glass is the most efficient way to save energy, and help to protect the environment, through glazing. This coating reduces the amount of heat lost through a window by reflecting the heat generated inside the building back into the room.

Our Windows

Timber

To be able to constantly produce high quality windows that will maintain their appearance and provide our clients with a lasting product that functions correctly for many years requires careful selection of the core materials to manufacture them from. K&D Joinery use a range of timbers to manufacture our windows from.

Our standard is Engineered softwood which is an enhanced timber product which is manufactured from selected defect free softwood timber sections that are laminated and “finger-jointed” together to form an extremely stable product from which we machine our timber window components.

In addition to this, we can manufacture using an Engineered Hardwood material which is manufactured like the softwood,
using only selected defect free sections of hardwood. Tests have proven that engineered timber components are 60% stronger that a piece of normal solid timber. It also improves the finish of the timber when put through our extensive spraying and finishing processes.

Our third option is to use Accoya which starts its life as a softwood, known as Radiata Pine. It then under goes a chemical treatment known as an acetylation process. This makes the finished product extremely stable and also extremely durable making it an ideal material for external joinery.

All the timber materials we use are sourced from companies that guarantee the sustainability of the products and all raw materials are delivered to us with a full chain of custody and Forest Stewardship Council (FSC) Certification.

Whatever materials the windows are manufactured in the window sills are all produced in solid hardwood for extra durability.
