The outward appearance of most replacement windows and doors can be almost identical, but don’t be fooled into thinking that all uPVC products are more or less the same! The quality of the materials, construction, overall design, locking and weather proofing systems can vary immensely from manufacturer to manufacturer. To help make you aware of the features you should consider when buying replacement uPVC windows, we’ve listed the main points to consider:
All these benefits are standard on our uPVC casement windows.
Fancy a change from white windows? Irish oak perhaps? Or maybe a sleek and contemporary anthracite grey? Our standard uPVC casement windows are available in a combination of smooth colours and woodgrain effect foils, all of which are durable, scratch resistant, can be easily cleaned and offer high performance and longevity in all types of weather conditions. We have profile examples of different standard colours available in our Bushey showroom. Other non-standard colours are also available on request but would require a longer lead time.
We specialise in the manufacture and installation of the Sheerframe® environmental sash window system. Available in smooth white, these vertically sliding sash windows are the perfect answer for period homes and period style properties, replicating the look of traditional timber sashes with the added heat and sound insulation properties of modern materials. Incorporating the very latest locking systems, adjustable restrictors and traditional timber aesthetics, our sash windows combine modern technology with traditional good looks for the perfect sash window.
The Sheerframe environmental sash window is acknowledged by architects, specifiers and planners as one of the most stylish designs in its class. A truly unique window that dispels the myth that traditional timber sash windows cannot be replicated in uPVC. It has even been approved for use within conservation areas across the UK and Ireland.
As a Sheerframe window fabricator, we offer total commitment to quality, in manufacturing,installation and service.
In addition to our Sheerframe sash window, we also offer our Universal sliding sash, available in white, cream, oak and rosewood woodgrain foil finishes. Superbly energy efficient window solutions coupled with the highest specification of locking systems, these box sash windows authentically replicate the look of timber but are virtually maintenance free. From six feet away it is extremely difficult to tell if the window is timber or uPVC.
Our Universal sash window is approved for installation in the Oxhey Village Conservation Area by Watford Council.
Our top of the range windows, these are truly innovative, maintaining the look and feel of traditional wood but with all the advantages of state-of-the-art modern window technology.

Research has shown that many homeowners assume that all double and triple glazing is equally energy efficient. In fact, there are huge differences in performance of different glazing configurations and it is the glass that makes the difference.
We install Planitherm Softcoat Total sealed units to all our windows as standard and we are members of the Planitherm Installer Network. Planitherm products are specifically designed to keep interiors more comfortable in the winter months and improve the home’s energy efficiency.
Planitherm products use a special coating to reflect heat from domestic heat sources back into the room, rather than allowing it to escape through the windows. At the same time, this coating allows free heat and light from the sun to pass through the glass, warming the room and further contributing to the energy efficiency of the windows and helping to reduce your energy bills.
As Europe’s leading energy saving window glass, Planitherm is the most efficient glass available today. Download our Planitherm guides and brochures from our Brochures and Videos page.
