Sliding Sash Windows Hampshire from KJM in Andover
Traditional homes require traditional windows and Hampshire based KJM’s vertical sliding sash windows perfectly suit Victorian style homes, many different types of older homes and indeed some modern homes too. We can install timber and uPVC versions and the results can look stunning with either system.
Our sash windows of choice are manufactured from Veka profiles or new for 2017 the Ultimate Rose Collection that are manufactured from uPVC. We also offer a timber sliding sash from our Dempsey Dyer range. These can be manufactured with traditional weights and pulleys.
The Veka Vertical Slider was one of the first on the market to be given an Energy A rating.
These windows also have a tilt back facility for easy cleaning, run through horns (as opposed to cheap looking stuck on ones) and travel restrictors (option) to really make a first class window for your home. The travel restrictors, restrict the amount the window can open. This enables you to leave your windows open securely as there is only a small gap left at either the top or the bottom.
The workings and history of a Sash window
Sash windows are an inherent part of British architectural history and were introduced in the late 17th Century. A traditional sliding sash window is usually made up of two sashes that slide up and down, modern ones can also tilt for easy cleaning. They were commonly used in Georgian, Regency and Victorian properties. The original timber window was counter-balanced, the weight of the glazed panel was balanced by a heavy steel, lead, or cast-iron sash weight concealed within the window frame. The sash weight is connected to the window by a braided cotton sash cord, or a chain, that runs over a pulley at the top of the frame. Modern uPVC sash windows are manufactured with spiral-spring type balance. The Veka VS uPVC double glazed window is available in many colours.

Ultimate Rose window
Every detail of the Ultimate Rose has been designed to replicate the charm and character of a timber sash window. With slim timber-like profiles and an industry-leading 35mm meeting rail, no other sash window can compete with it on style and authenticity. With period features as painstakingly detailed as joinery-style mechanical joints, a deep bottom rail, run-through horns and external putty lines, it would take an expert to spot that it’s uPVC. You won’t find any welds on an Ultimate Rose – everything is fully mechanically jointed. Using custom-designed jigs, blocks and brackets, every join on the frame and sashes is finished as a butt joint – just like a timber window. What’s more, the frame is joined horizontally while the sashes are joined vertically. Not only does this add strength and rigidity, it accurately mimics the way original timber sashes were joined. You can view all our window options in our showroom.
Astragal Bars on our windows
Astragal Bars can be fitted to any product enhancing the look of windows, doors & conservatories by giving them the traditional Georgian appearance of individual panes. They are fitted to the external face of the glass. Colours available are white or a choice of woodgrain foils. Using interbars on the double glazed sealed units gives the window an appearance of multi-panes.
The traditional timber sash windows that can be manufactured with your choice of cords and weights or the spiral balance operation.
Windows and Energy ratings
Spacer bars which conduct less heat at the edge of the glass are referred to as 'warm edge spacer'
The benefits are as follows:
- Reduced heat loss through windows
- Condensation on windows can be reduced
- Better sound insulation
Argon Gas filled sealed units
Filling the gap between the panes increases the thermal performance of insulating glazing units is to reduce the conductance of the air space between the layers. Originally, the space was filled with air or flushed with dry nitrogen just prior to sealing. In a sealed glass insulating unit, air currents between the two panes of glazing carry heat to the top of the unit and settle into cold pools at the bottom. Filling the space with a less conductive, slow-moving gas minimises the convection currents within the space, conduction through the gas is reduced, and the overall transfer of heat between the inside and outside decreases.
High-performance Low-E (low emissivity) glass is designed to reduce heat loss and must be used on energy rated windows. There are two types of low e glass, Hard Coat and Soft Coat, we use soft coat glass as it gives the following benefits over hard coat:
- Better light transmission
- Better U-Values
- Enhanced clarity/neutrality.
