Timber Casement Windows
Historically, casement windows (also known as cottage windows) were already in use in the 16th century in Britain. They succeeded the stone mullioned window and pre-dated sash box windows. Subdivided by glazing bars that joined together the small panes of glass, the earlier designs had the opening part of the window – the ‘casement’ – made of iron with lead latticing to the glass. By the beginning of the Victorian period, the frames and opening casements were made entirely of timber. Windows of 6-panes per casement were the most common pattern, but designs were occasionally elaborated by the use of Gothic arches or smaller panes, depending on the fashion in certain parts of the country.
The traditional flush timber casement became the most common window type by the second half of the 18th century. Casement windows started their career mainly in farmhouses and cottages. However, they abounded in palaces and wealthy households as well. Obviously, like anything else, the features of casement windows have developed over time, too. Initially, in Georgian era, only small glass panes were used. As the technology of producing glass developed and improved, so the panes of glass became bigger. Subsequently, the number of panes per casement was reduced to two with one horizontal glazing bar. However, smaller pane sizes become popular again in the Edwardian era. There are different types of casements and one of the more recognisable is one with leaded lights in different configurations. The panes can be square, rectangle, diamond, round, tipcat and other. It just testifies to the fact that, say what you will, but casement windows simply cannot be boring! They are smart, practical and attractive. They are flexible in a way that would suit every type of house, no matter what its style, periodic or modern.
Traditional casement flush windows have great aesthetic merit. In addition to that, their careful design pledges to keep your home wonderfully warm, quiet and extra secure.
Our challenge was to make casement windows which look simple but are in fact very sophisticated. Hidden away is modern technology – warp resistant timber, Roto® Secured by Design locks engage in multiple points around the perimeter of every opening, ventilation grooves, drainage channels and glazing units which lose much less of the heat in comparison with ordinary windows.

Why Our Timber Windows are the Right Choice?
To ensure your home stays secure, our windows and doors are fitted with advanced security locks, that lock at multiple points, including hook-bolts and deadbolts.
2. Security beads for internal use
Our glass panel is fitted from the internal side to prevent intruders from gaining entry by removing the glass.
3. Warm edge spacer bars keep our windows insulated.
Spacer bars are used to reduce heat loss and prevent condensation on the inner pane.
4. Outstanding clarity of vision
Advanced glass technology not only makes your home more thermally efficient, but also lets in more light than traditional windows.
5. Multi-layer timber sections with opposing grains are balanced
The multi-layered structure used as standard resists warping and twisting, as the opposing grains even out moisture movement.
6. The rebated glazing bead fills the gap between the window frame and the bead. T&G beading.
By rebating the glazing bead over the sash, we conceal the joint, eliminating cracking at the point where paint is prone to flaking.
7. Factory applied micro-porous coatings provide maximum protection while requiring minimal maintenence.
Every product receives a base coat of timber preservative, then a primer coat, followed by two coats of micro-porous paint. If you wish to change the colour of your windows then redecoration is very simple, as there is no sanding down required.
8. Our ventilation channels help prevent your windows from misting up
Double glazing units are protected from failure due to water damage by ventilation channels. In standard systems, misting can occur when glazing units are allowed to sit in water trapped within the frame.
9. Our glazing units significantly more efficient than ordinary double-glazed windows
All of our windows and doors incorporate double-glazed units with enhanced thermally insulating glass. They have a low U-value, which means they keep heat in during the winter and out during the summer. We further improve the efficiency of the unit by filling the cavity with argon gas and using low conductivity spacer bars to minimise edge losses.
10. Coloured silicone seals
A purpose-designed groove on the inside and outside of the window allows silicone to be applied to protect against water ingress. The silicone is factory applied, ensuring a perfect, unobtrusive seal.
