Double glazing for casement windows
Having your casement windows double glazed is easily done and its a great way of saving heat and reducing noise, without spoiling the character of your home.
In most cases, we would recommend slim line double glazing units, since they achieve maximum thermal efficiency whilst making minimum difference to the appearance of your existing windows. All our double glazed replicas can be manufactured to fit your existing casement frames, and are made with carefully selected sustainable timber for superior quality.
Size and thickness of double glazing for casement windows
The thickness of the double glazed unit that we fit will vary from window to window, but we usually use a 14mm slim line double glazed unit (2 panes of 4mm glass and a 6mm gap).
High quality slimline double glazing
The thickness of the double glazed unit that we can fit will depend on the thickness of the existing casement / side hung windows. These vary from window to window, but we usually fit a 14mm slim line double glazed unit (2 panes of 4mm glass and a 6mm gap). These have been approved by planning officers around the UK for use in Listed and Conservation properties and can be designed to meet Part L thermal building regulations.
Warmth and energy efficiency
If you’re finding it difficult to stay warm and cosy in your home, we can improve your house’s thermal insulation by using gas filled double glazed units. We have lots of different options – from argon and krypton to xenon gas.
Retrofitting: adding double glazing to your wooden casement windows
If you look at original casement windows, you’ll notice that the glazing bars (if present) – that the panes are positioned between – are relatively slim. They were designed to hold a single pane of delicate glass. The increased depth of a modern double glazed unit means that it’s larger and heavier, and simply wouldn’t fit in, or be supported by, the original timber glazing bars. That’s why we use slimline double glazed units. And depending on the style of your windows we can retro fit them directly into your existing timber casement windows.
Having double glazing installed was much quicker and cleaner than I expected, and we're really pleased with how they look.”Justin – BN6 – Hassocks
