What are Sash Windows?
Traditional timber Sash Windows are an essential feature of a period buildings character. Also known as a sliding sash or vertical sliders, they rely on a weighted system that allows the heavy sashes to lift and fall with ease. In order for the sashes to move in the box and operate smoothly, there is a 3mm gap between the sash and the frame which is often the cause of draughts, rattles, dust and rain ingress and heat loss. Dating back over 300 years sash windows as we recognise them today have steadily evolved as technology and fashion have changed. At one time, due to a punitive window tax, the size of your panes was seen as an indicator of your wealth and interestingly the design was influenced by the Great Fire of London when post-fire legislation required the windows to be recessed into the brickwork.
Double Glazed Sash Windows
Sash windows are renowned for their classic design and elegant appearance and can add a touch of traditional charm to any home. Originally, sash windows were made using timber frames. Over time, original timber sash windows present the usual problems relating to rotting frames, rattling, paint peeling off and draughts. To combat these problems, many people installed secondary glazing to try and reduce the amount of heat loss. Over time window companies began to manufacture windows using uPVC. Today’s modern uPVC sash windows are proving very popular as they are more are robust, energy efficient and are virtually maintenance-free. uPVC is not prone to rotting or warping like wooden materials. uPVC sash windows are highly durable and resistant to corrosion and weathering. New uPVC windows are also much more cost-effective than timber and can be designed to look exactly the same as a traditional style window. By replacing single glazing with Double Glazing you will immediately increase the comfort of your home as the rooms will heat up much quicker with no more cold draughts whistling through the old wooden frames.
Many people are now opting for a uPVC sash window simply because it is cheaper than the traditional wooden equivalent. Typically a wooden sash could cost more than 2 times the cost of a uPVC window.
A wide range of colours are available including coloured woodgrain foils. These replicate the appearance and texture of various types of wood to further emulate the appearance of timber sash windows better than conventional, spray coloured finishes. This is perfect if you live in a traditional property such as Victorian or Georgian, or if you live in a conservation area.
