Slimline Sash Windows

The Slimline Sash window has the sashes counter-balanced by spiral balances fixed to the inside of the frame in place of cords and weights but in all other respects it looks and operates in the same way as a Traditional Sash window – so much so that they are frequently supplied alongside the Traditional Sash window on the same job.

With no need for a weight pocket, the frame width is reduced (hence the name Slimline) and the window can be fitted in-between the window reveal and still retain a traditional appearance. This is of benefit in new-build properties and any other situation where there is insufficient room to hide the weight pockets behind the outer brick or stone face of the building.

The weight of each sash is balanced by a pair of pre-tensioned spiral balances, each individually tuned to perfectly match the weight that sash.

The spiral balances are made from torsion spring systems enclosed into a narrow tube. These tubes are positioned in-line with where the cords of a Traditional Sash window would be and can be fully-concealed behind additional timber facings if required.

As with the Traditional Sash window, the timber sashes on the Slimline Sash glide effortlessly up and down against the durable low-friction weather seals which surround them.

Examples of slimline sash windows

There is a wide range of fasteners for the window, available in a range of finishes including brass, chrome, bronze & pewter. These cleverly aligning both sashes and draw them together against their seals whilst matching hook lifts provide lifting points for moving the sash. For a truly authentic appearance hook rings to the top sash and D-handles on the outside can complete the look. All of these sash windows are available with a choice of sash-stops which only permit limited opening of the sashes unless full-opening is required and optional locking fasteners which prevent the windows from being opened from outside.

These timber sash windows can be supplied with one opening sash, two opening sashes or none and in both rectangular and shaped frames to match the existing window aperture.

There are various optional sash horn designs which can be shaped onto the inner and outer sashes.

These windows are available with a variety of different glazing options. Generally double glazing is the preference but to cater for the needs of Listed Buildings we have both single and heritage-style slim double glazing (which can be fixed in with timber beads or putty-glazed) and for those with problems with noise then we have triple glazing or specialist acoustic glass.

As with all our products, the high-quality paint system gives excellent protection against the elements for up to 10 years before re-coating is required. The flexible water-based micro-porous paint won't flake or crack as it ages, keeping the timber beneath it protected for years. Repainting is simplicity itself, usually requiring no more than a quick rub down with fine glass-paper and re-coating with top-coat.
