Stormproof Casement Windows

What Are Stormproof Casement Windows?

Stormproof casement windows are also known as lipped casements, as the lip prevents the window from going further into the frame as with a flush one. Stormproof casement windows replicate the style of one of Britain’s most common design of casement windows but are known for their weather protection against the extreme elements which we often face over here. These wooden casement windows are outward opening with the sash overlapping the frame. This simple yet effective design adds extra protection against unpredictable and wetter weather conditions, hence the name ‘stormproof’. The ‘easy-clean’ hinges allow the sash to open to a 90° angle, but also with a sliding function so that easy cleaning of the outer pane is possible. Additionally, this type of window may be equipped with fire escape hinges in order to be utilised as an emergency exit.

Our Stormproof Casement window meets the requirements of PAS24 and with the fitting of compliant hardware, the requirements of Lifetime Homes.

Why choose Timber Windows?

Our timber Stormproof Casement windows are ideal for all type of properties and conservation areas. You can get the look of an authentic timber window with all the modern benefits. Timber framed windows can contain double or triple glazed glass to ensure sound and heat insulation but offer that classic, heritage feel. Not only do they look beautiful, precision crafting and advanced technology mean that they’re highly energy efficient, easy to operate, secure, rattle-free, and energy efficient.
