Externally the window is capped with powder coated aluminium which can be in any RAL colour of your choice.
Authentic Construction
Alu-Clad Sash Windows
Our alu-clad sash windows are a spring loaded design which gives them the look and feel of a traditional sliding sash windows however gives us more space for the two sashes enabling us to install larger glazing than previously possible as well as the extra aluminium capping. This design overcomes many of the disappointments often seen with aluminium clad sliding sash windows and offers a more energy efficiency window than is usually available in a sliding sash design.
All Knight Collection windows as standard and are equipped with a patented locking system which offers enhanced security protection for your home.
Our Alu-clad sash windows are manufactured with a spring balanced mechanism giving the look and feel of traditional box weighted sash windows however saving on space. This design allows us for more space for the two sliding sash windows which in turn enables us to support thicker glazing up to 36mm. This means that we can now support triple glazing in our aluminium clad sash windows enhancing the overall U value of the windows. We also have a range of other possible glazing options such as standard argon filled double glazing and ultra this Krypton filled double glazing units to give the look of single glazing with the energy efficiency of double glazing.
Manufactured with a timber core our sash windows have the majority of the features found on original sash windows from yesteryear including a thin top and mid rail, deep bottom rail, mechanical joints, authentic putty and glass lines as well as various astral and Georgian bars available.

Meranti
This exotic species of hardwood timber from Indonesia has extremely high resistance to weather conditions. The windows made of this material are not only durable but also very warm and quiet. Meranti wood density strongly depends on the species and can range from 300 kg/m3 to 1050 kg/m3 . It is recommend for places exposed to moisture. In windows and doors production most commonly used meranti is the one with a density above 450 kg / m3 , which ensures consistent quality of the final product.

Each layer in the Teknos Aqua system has been carefully formulated both for its specific purpose and to work in synergy with the other products in the system to achieve maximum performance, including:
- Vacuum impregnation, wood preservative and combi primers product to preserve and prime the wood.
- Primers to fill the wood's pores and provide an anchor for intermediate or topcoats.
- Specialist primers and intermediate coats to block and inhibit tannin staining.
- End grain and construction joint fillers to protect the most vulnerable areas of exposed joinery.
- Intermediate products to fill the pores of coarser wood species, providing a more uniform surface for top coating.
- Flexible, micro porous topcoats for an attractive, durable yet flexible surface.
