A Brief History of Box Sash Windows
Wooden sashed windows have been used in traditional British homes for centuries. During the 17th century, the traditional sash window was invented as a way to provide more ventilation and light into rooms that would otherwise be too stuffy and dark. By the 19th century, this traditional sash window had evolved into what we know today as the Box Sash window.
Box Sash windows are the quintessential classic style of window found in period homes, usually with two sashes that slide open vertically up and down within the frame of the window. Originally constructed from timber and single-glazed, Box Sash windows are renowned for their charming appearance as well as their practical use. Nowadays, these windows can be made from cheap alternative material like UPVC and can be double glazed for extra insulation and energy efficiency.
How Are They Constructed?
Box sash windows, also known as sashed windows, are an attractive and traditional style of window that has been used in homes for centuries. They consist of two sashes, one sliding over the other, and are usually made from timber.
The construction of box sash windows starts with the frame which needs to accommodate and hide the weights, which counterbalance the weight of the openers so the window can open and close easily.
The timber frame is usually made from either softwood or hardwood, depending on the type of window and the budget. Once the frame is constructed, it is fitted with a weather seal to protect it from the elements.
The next step is to attach the two sashes, or panels, to the frame. This is done by fitting them into grooves that run along the sides of the window frame. Modern box sash windows are typically equipped with metal weights for health and safety reasons.
Finally, the window is sealed by fitting special flexible gaskets between the sashes. This ensures that the window stays airtight and prevents drafts.
Box sash windows show off a unique and attractive style to any home. They are well-constructed and durable, making them a great choice for anyone looking to add a classic look to their home.
