Opening functions
Fixed, guided or fully reversible… you can specify your window combinations and also how you want them to open without compromising on design.
Fixed casement
Ideal for maximising internal light and making the most of attractive views. Fixed windows have the same slim profile as opening sashes in order to deliver a uniform appearance.
Top guided
When opened, the sash provides a ventilation gap at the head. Adjustable friction ironmon- gery allows many different choices of opening positions. This is ideal for kitchens or bathrooms where there may be obstructions, such as worktops or taps, as the handle is positioned at the bottom of the window frame.
Side hung
Side hung windows open up to 90°. This allows the windows to fully open, and enables these units to be used as part of a fire escape strategy.
Side guided
When opened, the hinge side of the sash moves towards the middle to create an opening that allows the glass to be cleaned from the inside.
Top hung fully Reversible
The sash can be rotated up to 170° to allow cleaning from the inside. The window can be reversed to the cleaning position where an automatic catch keeps the window in place.
Glass to glass corner windows
An ideal way to make the most of external views, without the disruption of corner posts, and to maximise natural light internally.
Let energy in – and save on heating
VELFAC windows are specifically designed to generate more energy than they lose – reducing heating bills and CO2 emissions.
Energy Efficient
Our most energy efficient composite windows meet the ener- gy requirements of today and tomorrow by actively generating more energy within the home – in the form of light and heat – than they lose.
Triple Glazed
VELFAC 200 ENERGY is triple glazed to maximise energy efficiency. You can easily combine it with the double glazed VELFAC 200 window system without any visible difference to your façade.
Low-Energy Glazing
Ideal for all types of houses, both low carbon and traditional, VELFAC energy efficient windows feature low-energy glazing as standard, as either double or triple glazing.
Reducing Heating Needs
Our windows can reduce your heating needs while also helping maintain a better indoor climate, saving potentially hundreds of pounds in energy bills.
Details that make the difference
With VELFAC, you can choose the ideal colour for your new windows and you can specify different colours for internal and external frames. The external frames can be finished in any RAL colour, granite or metallic. VELFAC Standard RAL colours come a no additional costs.

What Our Clients Say
See All TestimonialsNigel and Mia
Luke and James came over this time on the last of our three planned installation visits to fit our final Rationel door and some requested extra restrictors. They checked all the rest of the VELFAC windows and Rationel sliders, adjusting a couple, and nothing was too much trouble. We have dealt with several folk at Westcott for our whole house install – and ranging from sales, through logistics, accounts to the Dovista rep on a couple of tech queries. Even with Jeremy Westcott directly to resolve something. Everyone is great – as are the products and the service. Couldn’t recommend more highly.
Roger, Charminster
I would like to thank you for a great service in installing the windows in the two houses. The team were brilliant and we are very pleased with the final result.
Lance, Farnham
I had 18 windows and doors replaced with Rationel and Westcott Construction were the recommended supplier. Josie was very helpful while we got the exact specification sorted out, and was always quick to reply on email. The fitters were very friendly and helpful, and the attention to detail was excellent. Everyone turned up when they said they would and completed the job on time. This is a very well organised company who it has been a pleasure to work with.
