Product Overview

Heritage Solution

This window is commonly referred to as the “timber alternative”. With its woodgrain design and additional features such as decorative horns and deep bottom rails, it is easy for you to design this window to replace something a lot older but at the same time upholding/improving the aesthetics of the property whilst staying inside budgets.

Easy clean facility

The sliding sash windows come with an easy clean tilt facility as standard (excludes woodgrain external and smooth white internal windows), which allows both top and bottom sash to tilt inwards. This is especially handy for cleaning the upstairs windows without having to climb a ladder or pay someone else to do it.

Energy Efficient

The glass specification is the most significant component when affecting the windows overall thermal efficiency. Each sliding sash window is supplied as standard with 24mm double glazed units incorporating Edgetech’s TruePlas spacer bar and manufactured in accordance with British Standards.

Sash windows are a design classic. Once the standard style of window across the UK, over time, sash window designs were superseded by more contemporary alternatives. Sash windows are still highly popular, not least in period properties, where the classic design fits the overall appearance of the property.

In the past, sash windows were typically constructed from timber, but over recent years developments in window technology have seen the emergence of modern alternatives. uPVC sliding sash windows are growing in popularity, combining the traditional design of sash windows with minimal maintenance and the energy efficiency of uPVC.


Why consider uPVC sliding sash windows?


UPVC sliding sash windows combine classic style with modern function. They have been designed to replicate the looks and feel of traditional vertical sliding sash windows and consist of two sashes that slide vertically past each other within the frame.

This iconic design became widespread in the UK during the 19th century and remained the preferred style of window well into the 20th century. They work on a classic pulley and weight system and allow for easy opening and closing for effective ventilation.


How do uPVC sliding sash windows compare to traditional wood?


Unlike traditional wood sash windows which can rot, warp, or become damaged over time, uPVC sliding sash windows are highly durable and generally resistant to the elements. They are less susceptible to corrosion, adding to their longevity. Unlike wooden designs, uPVC sliding sash windows only require minimal maintenance and can easily be cleaned with soap and water. They don’t require regular painting or staining to maintain their appearance over time.

The installation process involves removing the old windows, preparing the opening, and then fitting the new windows and mechanism. The edges are sealed to prevent drafts and moisture from infiltrating.


Energy efficiency and security combined


uPVC sliding sash windows now feature multi-chambered profiles that help to reduce heat loss. Providing excellent thermal insulation all year round they help to keep homes warm in the winter and cool in the summer, resulting in lower energy bills and reduced carbon emissions. Modern uPVC sliding sash window systems also feature multi-point locking systems for added security and valuable peace of mind.
