PVCu Sliding Sash Windows

Traditional Characteristics

Windows are so much more today than simply a way to illuminate the inside of your home. Our Legacy sliding sash windows, give you the opportunity to introduce wonderful character and identity to your home while keeping you safe and warm

The traditional sash window was purportedly invented by Robert Hooke (of Hookes law fame) around 1670 and is a wonderful reflection of Victorian and Georgian English properties with their elegant curves and robust design

In a modern twist we have sympathetically re-engineered the window in a robust low maintenance PVCu with a myriad of decorative options including sash horns, glazing bars, and a deep bottom rail to replicate the style of yesteryear

Superb Thermal Efficiency

Today’s window designers have far more challenges than previous generations. Not only do they need to design windows to withstand the elements, but they have to consider the environmental impact too

Up to 'A+' Energy Rated

Our sash windows include brush seals around the openings for exceptional draught proofing and to assist the environment. ‘Low E’ glass together with a warm edge spacer bar provide exceptional heat retention, and a superior ‘A+’ energy rating where required

Recyclable PVCu

Selecting PVCu is an environmentally friendly choice, as the majority of end of life PVCu windows will be recycled

By choosing our sliding sash windows you are not only keeping your home warm all year round and reducing your heating bills, you’re also helping the environment

Fire Escape

If your window opening isn’t large enough, you have the option to request an egress fire escape facility. We always recommend checking the current compliance with one of our product experts

Peace of Mind

Our Legacy sliding sash windows have been designed with not only elegance and authenticity in mind, but security too. The sliding sash windows are iconic

PVCu Sliding Sash Windows multi-chambered and reinforced to prevent deflection through differing climates. This reinforcing also acts as secure fixing points for handles, latches and other screw fixed components. The balances maintain the equilibrium of the sash window at all points of travel and robust locking devices enhance the security of your home

Secured by Design Upgrade

If you would like to take the security of your sliding sash windows a step further you can also opt for the ‘Secured by Design’ package, which incorporates all of the enhancements from the PAS 24:2016 but with the additional inclusion of 6.8mm acoustic laminated glass supplied by Pilkington

PAS 24:2016 Upgrade

Upgrade the security of your sliding sash windows by taking advantage of our PAS 24:2016 security package. This enhancement includes the following four upgrades. This is generally mandatory on new-build projects

Reinforced Tilt Latches

Upgraded Locking Keep

Upgraded Lock x2

Top Sash Security Blocks

Please note that the Fire Escape, ‘Secured By Design’ and ‘PAS 24:2016’ upgrades are not standard and must be requested as part of the window specification

Legacy Features

Slide and tilt facility

As standard, our sliding sash window comes with a slide and tilt facility*, allowing you to clean both the top and bottom sash from inside your home

*Please note that on windows with a woodgrain finish external and smooth finish internal we are not able to offer top sash tilt facility

Seamless Corner Welds

We are proud to offer a seamless welded sash window. This revolutionary process now disguises the external 45-degree corner welds with a flush mitre providing a far superior aesthetic finish. Available on woodgrain windows only and a mininimum window size of 475mm wide x 900mm high

Legacy Sash Horns

Enhance your window by choosing either run-through or plant-on sash horns. The run-through utilises mechanical joints rather than welded to allow the horn to be a continuous part of the sash giving the window a more authentic overall look. The plant-on is a sculptured moulding that is fixed to the underside of the top sash

Deep Bottom Rail

Choose a deep bottom rail if you you want your sliding sash windows to look as close to the original timber version as possible. The larger bottom rail sash convincingly mimics the timber sash windows of old. The deep bottom rail is available with welded or mechanical joints

Trickle Vents

Although a well-insulated home is important, a well-ventilated home is equally as important. Trickle vents provide background ventilation and are generally mandatory under Building Regulations. An internal flap enables the vent to be opened and closed as required

Legacy Hardware

Travel Restrictors

The travel restrictors limit the opening of the top and bottom sashes to approximately 100mm. They are primarily used as a safety feature in locations where opening restrictions are needed. The magnetic mechanism can be overidden from inside your home allowing for a larger opening.

Sash Pull

All our PVCu Sliding Sash Windows come with one or two sash pulls as standard depending on window size. The sash pulls are usually fitted on the inside of the bottom sash to allow easy opening

D Handle

Designed to be fitted to the underside of the top sash on the outside of the window to assist with the opening and closing of the window. Alternatively, you can request the D handle to be fitted to the inside top sash

Pole Eye

Primarily designed to be fitted to the top rail of the top sash. The pole eye enables use of a pole with hook (not supplied) to operate any windows that are positioned too high to operate by hand

Locking System

Our locking system holds the sash window shut by fastening the mid-rails together. The locking system is available in two styles. You get one latch on windows up to 1,000mm wide and 2 on windows over 1,000mm wide

Sash Knob

Used to open and tilt the sashes for easy cleaning of the outside frame and glass from inside your home

Hardware Colours

Our hardware is available in eight different finishes

Please note that our travel restrictors are only available in white, chrome, gold and satin chrome
