Wooden sash windows are beautiful but require years of painting and can experience problems with wood expansion or contraction causing the sashes to stick, rattle and be draughty. Everest uPVC sash windows are made of highly efficient uPVC which will never expand or contract and requires no painting meaning your windows will always run smoothly. Moreover, our uPVC sliding sash windows are made with top of the range weather resistant Q-Lon weatherseals, guaranteed for a lifetime, never to perish keeping your home free of draughts and enabling our uPVC sliding sash windows to achieve an A rating for thermal efficiency.
Everest take the extra step to make sure our traditional design provides the most up to date levels of security. We offer two levels of security with both top and bottom sash restrictors so windows can be left open for ventilation whilst restricting access, as well as fitch locks. Fitch locks are traditional sash locks but are key lockable and secured into galvanised Steel reinforcement and adhere to the high standards set by 'Secured by Design', a police affiliated home security accreditation.
Everest uPVC sliding sash windows are fitted with spring balances, this assists the lifting and closing of the sash window so the window can be opened and closed with minimum effort. We then use advanced brush seals on the running surfaces to facilitate easy opening. In addition, Everest sash windows offer a tilt-in-hinge design which makes cleaning the outside of the window from the inside very simple, saving on window cleaning costs and an ideal solution for top floor windows.
A spiral balance system sits within the frame and uses a series
of springs to counter balance the sash to ensure a smooth opening mechanism. This spiral balance system replaces the cords and weights system used in traditional sliding sash windows, giving a slimmer window profile resulting in more sunlight and warmth. Traditional sash windows are likely to be fitted as 'box sashes' and replacing these traditional sashes for uPVC is a specialist task which must be performed by a qualified installer. Everest installers are trained to the highest standards and ensure that our uPVC sash windows stand the test of time.
All Everest uPVC windows are fitted with an internal
glazing bead for two reasons. Firstly, it ensures the window is much more secure than if the glazing bead was put on the outside. The glazing holds the Glass in place and if it is inside your house then it prevents potential unwanted visitors from removing the beading and glass and gaining access to the property. Secondly, it means that glazing can be fitted from inside the property, removing the need for glass to be carried up ladders or on to scaffolding and making installation a much safer process.
On the underside of the top sash section there is an optional component known as a horn. There are two types of horns: plant on horns and through horns. The through horn gives the window a look more closely resembling the construction of original wooden sashes and is much more pleasing on the eye the bottom section is butting against the side section as seen below. The through horn offers a richer more authentic aesthetic with the bottom section butting against the side sections.
Our windows can be ordered with an authentic wood grain finish which is very hard to distinguish from a true Timber window. This is achieved through the application of a micro metre (a lot thinner than a mm) foil which perfectly mimics the look and texture of wood, giving the frame an appearance which is very similar to wood but with the energy efficiency and maintenance benefits of uPVC.
We offer the most popular styles to complement a variety of sash windows with our entire range available in three finishes covering the traditional to the more modern.
