Traditional look with stormproof performance
Our traditional looking double sealed window offers customers a traditional look while allowing for an espagnolette locking system and double seals which gives it a much higher performance compared to the traditional casement window. The windows performance is also superior to a stormproof window. Designed by JM Joinery, in 2010, the double seal window's low U-value and energy saving features are fast making it the most popular window in our range. Below are a few images to help you understand and get familiar with the system.
This image shows the cross-section of the casement and frame. As you can see the casement still finishes flush, like a traditional window, but when the window is closed it compresses on two separate seals. We also fit a head drip above the casement to ensure no water can work its way under the head of the frame and put pressure on the seals or sit on top of the casement.
The double seal window is an extremely secure and safe window to own. The espagnolette window locking system allows you to have a 3 point lock in comparison to a traditional window single lock. Due to the double seal window being flush finishing it is also more secure than a stormproof window which offers itself to being levered open by a bar.
The espagnolette locking system also allows for a night vent and child restriction opening hinges.
We want to make sure that the windows we make have the best performance possible, so we take extra steps to protect them.
All our windows are treated with end grain sealer to prevent any moisture being drawn up into the timber. We also drill weep holes in the glass rebate, to allow any moisture to be released, preventing glass breakdown and to avoid water sitting on the surface of the wood for too long. These are just a few of the steps we take to ensure the life of our windows is as long as possible.
Our windows can be glazed with both double glazed and triple glazed units. We supply U-value certificates to all our window customers which state the energy efficiency of each individual window.
