Double casement window 20 light

SKU: DB0220

Choose the material for your window or door. For most of our products you can choose between pinewood or aluminium clad pinewood. For alu/clad products the exterior of the product has a 1 mm alu cladding.

Choose the glazing. The options depend on material and model. Read more in the info box (?).

Choose the type of glass which fits the purpose of the window. You can choose between ordinary clear glass and different types of obscure glass.

Building Regulations guidance (Approved Document K): Standard (non-safety) glass may only be used where the bottom edge of the glazing is more than 800 mm above the finished floor level and not within 300 mm of a door opening. Glazing that is below 800 mm; in a door; or within 300 mm of a door edge and below 1500 mm: these must use toughened or laminated safety glass (or be protected by a suitable barrier).

Choose the exterior colour of your product. If you choose "Special RAL colour" please send an email with the desired RAL color. We only produce four-numbered RAL codes (RAL Classic). Please note that we do not offer 'Special RAL colour' for aluminium cladding. For glazes and clear lacquer there can be minor colour differences as the wood is finger jointed.

Choose your glazing bars. The glazing bars are glued on to the glass on the inside and outside of the window, for a modern and energy saving solution. Choose Georgian bars, if you want the glazing bars to sit inside the glass unit. This makes the job of cleaning the windows easier.  

Spacers in between the glass panes and glazing bars  can be chosen as an add-on.

A "warm edge" spacer improves the insulating qualities of the glass.

Choose the interior profile for your wooden window. The Softline profile has smooth angles giving your window a modern and stylish look. The Classic profile comes with special frame and casement moulding for a more classical look.

A groove on the inside frame makes the fitting of casing trims or internal window sills easier. The groove is 10 mm deep and wide.

Aluminium water drip-rail is available in the same colours as the outside of the window, or they can be anodized. The drip-rail leads the water away from the window, to prevent stagnation of water. 

Choose your desired handle.
