Sliding Sash windows. Classic elegance, modern engineering.

The Lorimer Sliding Sash

Traditional sash and case windows are typical of Georgian, Victorian and Edwardian houses in Britain. With sashes, the panes slide rather than swing, moving up and down in the window case.

The Lorimer Sliding Sash is designed to look just like traditional timber windows – in fact it’s hard to tell the difference just by looking. But our sash and case windows need no painting or maintenance, they won’t rot or warp, and they deliver excellent thermal performance and noise protection.

Sills and surrounds

While uPVC sash windows perform much better than timber, it’s still a pleasure to have the beauty of wood indoors. Ours come with internal sills and surrounds in a choice of hardwoods – Natural Ash, American Cherry, Royal Oak and Far Eastern Mahogany. The hardwood sills and surrounds are hand-finished in varnish or wax. We can alternatively offer an engineered wood, finished in brilliant white if this would suit your home better to match existing window panelling.

Window colours

Your Lorimer uPVC sliding sash windows will normally be the same colour inside and out. White makes your room look bigger, while traditional rosewood or American light oak woodgrain finishes help to replicate the appearance of timber windows.

Decorative Finishes

As with all our window types, you can choose smart white uPVC which will never yellow, or any one from a range of colours and finishes, inside and out. Sliding Sash windows in bright white can make your room look bigger, while traditional rose- wood or light oak woodgrain finishes gives a richer, more opulent effect.

What is uPVC double glazing?

Double glazing is the term used to describe two panes of glass within a frame, fitted to reduce the loss of heat and reduce noise. Traditionally, windows were single-glazed until the late 1970s. The CR Smith Lorimer window uses the latest double glazing technology that is available on the market today.

What are the benefits of installing CR Smith’s double glazed windows?

There are many benefits to choosing CR Smith Lorimer windows. Our ultra-slim frames are designed to maximise light, each window is styled to suit the features of the property and everything is always fitted to comply with current building regulations. All of our windows (and doors) come with a 10 year product, installation and security guarantee as well as a certificate for building regulations compliance .

What makes Lorimer double glazed windows unique?

Unlike the majority of double glazing companies, we engineer and manufacture most of our products ourselves. We feel this offers customers the best value for money and a high quality product, with Lorimer designed specifically for Scottish homes and the Scottish climate. The Lorimer range exceeds recommended Scottish Building Regulations and is available in a range of window styles and colours, including Casement, Tilt & Turn, Reversible and Sliding Sash. It is also used as standard in all CR Smith Orangeries, Conservatories and Sunrooms.

Does Lorimer Double Glazing save energy?

All Lorimer windows are A-energy rated as standard, which is the highest energy efficiency rating possible. Lorimer also comes with a unique fitting detail to provide the warmest, most secure window on the market so that this energy efficiency is maintained.

Are your uPVC double glazed windows bespoke?

Yes, all Lorimer windows and doors are made-to-measure at our custom built manufacturing plant in Cowdenbeath, Fife. We feel that manufacturing most of our products ourselves offers customers exceptional performance, quality and guarantee.

How long does it take CR Smith to install my double glazed windows?

Our time-served joiners will fit about four windows per day, depending on the style and finish required. By limiting the number of windows fitted, we can ensure the highest level of detail and quality is achieved.
