This is our 1000mm x 350mm standard high level single cabin window.
The measurements shown are over all frame size. The window has draught excluder all round and is secured by 2 adjustable Scandinavian latches, 1 at the top corner and 1 at the bottom corner which clamp the sashes tight into the draught-proofing seal and makes it a very solid fit.
The hinges are also adjustable, making it a very easy item to fit and maintain.
The single glazing is made of 4mm float glass
It is very important to note that the beading has an inset rebate which is utilised to seal this joint with silicone mastic as well, giving a totally waterproof seal.
