A choice of 24 standard paint colours are available, along with a selection of translucent finishes. Special colours can also be produced to match any sample or RAL reference number. The manufacturer can also provide a combination of two-tone internal/ external.


David Salisbury has carefully selected the best timber for each application within our product range. Our frames, sashes and roof timbers are manufactured from Engineered Siberian Larch where a solid colour finish is required unless otherwise specified. Engineered Sapele is utilised in decorative fascia and pilaster applications. Where a translucent finish is required, we will manufacture from Engineered Sapele only. Where requested, we are also able to offer FSC® certified products sourced from responsibly managed forests (FSC® C002189). Glazing bead and bonded bar sets are manufactured from Qwood where the product is non-translucent and does not have any curved beading or bars. Qwood is a composite derived from timber sourced in sustainably managed forests. For any product requiring a translucent finish or curved beading or bars, Sapele will be used.

Factory glazing:

David Salisbury casement windows are all glazed in their workshop by a highly skilled team of glaziers. Their external beading profile is designed to replicate the look of a traditional bead, but utilizes their modern manufacturing techniques and concealed pin system. They use toughened safety glass to BS 6206 as standard.


A range of double glazed units can be accommodated, including slim-light units, internal blinds and switchable glass. The manufacturer recommends a soft-coat low-e glass filled with argon gas for improved thermal efficiency. They can utilize various other options to improve U-values, reduce heat gain or to ensure greater security. Units can also be upgraded to achieve a BFRC approved A rating. Etched or patterned glazing can also be incorporated.

  • 24 mm double glazed sealed units manufactured to a 4-16-4 configuration. Conforms to BS 5713.
  • Toughened safety glass as standard.
  • 44 mm triple glazing available (requires increased timber sizes).
  • Factory glazed using a fully sealed system.
  • Low emissivity, solar control, tinted, easy-clean, obscure and laminated glass are all available as options.

A choice of 18 mm bonded bars or 44 mm (32 mm with slim-light glazing) through bars allow a full range of fenestration options, from Georgian multi-pane units to semi-circular or Gothic beading configurations. Highly skilled craftsman and precision engineering allow the creation of very complex fenestration designs to an extremely high standard.

GT clip system:

The GT framing clip system offers easy site installation for non-opening sashes without the need for messy, on-site glazing. The pre-installed clips slot into the relevant locations giving a quick installation whilst providing a strong, weathertight seal.


The manufacturer offers a range of interchangeable frame and sash moulds allowing the designer to further customise their windows. Internal frame moulds are available in Ogee, Ovolo or Square moulds. Internal sash moulds are available in Ogee, Lambs Tongue, Ovolo or Square moulds.

Multipoint locking:

All casement windows are fitted with multipoint locking as standard. Espagnolette security locking system and double mushroom keeps also offer a night vent option whilst providing the peace of mind of a high level of security (side hung and top hung fanlights only).


External sill nosings are fitted onsite into a pre-cut groove in the framing. These come in a range of projection sizes: 30 mm (stub), 80 mm (standard), 100 mm or 130 mm (extended). Internal painted windowboards can also be supplied on request. These are available in MDF or hardwood and slot into a pre-cut groove on the inside of the frame.

Weatherproofing gasket:

The windows are weatherproofed using an EPDM double gasket system providing superior weatherproofing, draught exclusion and thermal performance. Windows are weather tested to DIN EN 1027 and air permeability tested to DIN EN 1026.


The manufacturer's experience and advanced manufacturing techniques mean that they can produce extremely technical designs and products such as curved glass windows. Where practical, they can alter rail or style widths to any design to maximize glass area, finish and glass specifications to suit and include ironmongery options from a vast range of suppliers. Their experience delivers the quality of product whilst still providing the control and ability to personalize joinery.
