Sliding Sash Timber Windows (Box Sash Windows): The clear choice!

Timber Sliding Sash Windows and Doors

From a single timber sash window to a multiple order, each and every sliding sash window is manufactured in our workshop where we combine the latest standards of weatherproofing, thermal performance and security with the very best of traditional designs. We specialize in projects for listed buildings and buildings within conservation areas as we are able to match existing details and therefore conform to local planning guidelines.

All our box sash windows, doors, conservatories and lantern roofs are low-maintenance and designed to enhance your property. Timber Windows (including A rated timber windows) can be supplied to meet any required finish and all work is manufactured to appropriate British Standards. In addition, they are individually customized with your choice of timber, ironmongery and finish and full manufacturing drawings are produced to your exact dimensions for approval.

Box Sash (Vertical Sliding) Timber Windows

Our sliding sash timber windows are made to the highest standards, using primarily solid, top quality hardwoods and customised to suit your design and specification. They are fully draught-proofed, manufactured using state-of-the-art CNC jointing technology and finished with three coats of microporous paint, to your colour choice. A full range of options is available:

Curved or square head windows.
Traditional weights, cords and pulleys.
Double or single glazing.
Extended sills if required.
Your choice of moulding (to match existing if appropriate).
Horns – style and length.
Ironmongery to your specification – style and finish.
Choice of timber.
Integration of your security system.

Timber Spiral Balance Sash Windows

As a cost effective alternative to traditional weights, cords and pulleys, we can offer spiral balances (sometimes called spring balances). These balances can offer up to 70-75% weight assistance, but must be fitted with travel stops. Other details are as Box Timber Sash Windows.

Ironmongery

Our joinery is of exceptional standard so we only use the very highest quality ironmongery to complement it. We can supply a variety of finishes and styles to suit your requirements or to match existing ironmongery.

Hardwood Timber Types

We use timber that is machined and detailed in our own workshop. Idigbo or Red Grandis is often used as our standard timber when a painted finish is required. Both have excellent durability, lifespan and takes our finishes extremely well. In addition, other timber such as Accoya or Oak are available.

Timber Finish

We offer a range of finishes to suit the location, timber and your preferences. When a painted finish is required, we use three coats of factory sprayed micro-porous paint – any colour, to your taste and samples are available for you whenever needed.

Glass Options and Specifications

A range of double glazed units can be accommodated, including slim double glazing units. We always use softcoat low-e glass units filled with argon gas for improved thermal efficiency and we can fit various other options such as solar control coatings to reduce solar gain. Etched or patterned glass can also be incorporated.

Quality Craftsmanship 

Your sliding sash timber windows are machined, joined, finished and glazed in our workshop using the very latest in timber machining technology. The whole process is under our control and your sash windows leave our workshop fully factory finished, wrapped and ready for installation.

Installation Option

As well as the manufacture of superior quality timber sash windows, we can also offer an installation service for the majority of the  UK. If you require replacement sliding sash windows or other joinery items please contact us and we will provide a detailed quotation.

Customisable Sash Window Sections

Where practical, we can alter timber sections to your own design or to maximise glass area, finish and glass specifications to suit you and ironmongery options from a vast range of suppliers. Our expertise delivers the quality of product for which Clifton Joinery is renowned whilst still giving you the control and ability to personalise your joinery.
