Only engineered timber is used to manufacture WWL windows and doors. This provides superior strength, stability and a knot-free finish – qualities for which our products are renowned.


The quality finish of WWL timber windows is obtained using highest quality ecological spray applied, water based, micro-porous finishing system. The finishing coat is elastic and moves together with the wood as well as lets the wood breathe.

A wide variety of RAL and stain colours are available to meet our customers’ requirements. All of our paints and lacquers are environmentally friendly, ecologically clean and harmless to the environment.

Available combinations of window colour:

  • lacquer both sides;
  • lacquer one side and RAL colour other side;
  • RAL colour both sides;
  • different RAL colour on each side.

The right glazing can save you money, keep warm air in, protect your home and regulate light and temperature. Homes across the world differ in their local climate, construction materials, orientation and size. Moreover, each window of that home has a different purpose. Bathroom windows need to provide light and occasional ventilation but cannot be see-through. Skylights should provide maximum light but pose little risk for forced entry. Patio doors however should be large, offer maximum views but be difficult to break. Modern glazing offers solutions to each of these needs both alone and in combination.

What is Secured by Design?

To answer this question simply, Secured by Design is a police initiative that strives to improve the security of both new and existing homes in the UK. Established in 1989 the initiative was developed to improve overall security in both the design of the properties and through the use of enhance security products in their construction.

I know we need to comply on our development so how do I ensure windows & doors comply with Secured by Design?

Firstly, windows and doors need to be independently tested by a UKAS accredited test house to meet the requirements of the security test PAS24:2012 or PAS24:2016. Secondly your window and door supplier must be a Secured by Design product licence holder; whereby both the products and their production are third party certified being regularly audited to ensure specifications manufactured continue to be as tested. Always check your supplier can provide a Secured by Design licence number and certificate.

How does the PAS24 test ensure my windows and doors are secure?

A series of tests are carried out under the PAS24 test regime, these include; a manipulation test using small tools such as paint scrapers and screwdrivers to attack the product, glazing removal test using chisels to attack the glazing infill in an attempt to remove the glass and mechanical loading and impact resistance tests whereby impact is imposed on the doors hinges, locking system and to the body of the door leaf or opener of the window in an attempt to gain entry.

For windows and doors to pass this rigorous testing regime enhanced security features are necessary; features such as; robust frame sections, TS007 compliant door cylinders, laminated security glass to BS EN 356:2000 P1A on easily accessible windows with non-key locking hardware and external doors and TS003 compliant door chains.
