Traditional Sash Box Windows
Sash box windows have been used for many years in Victorian and Georgian properties but have recently regained
popularity for those who wish to give a more classical look to modern houses.
Traditional Sash Box Windows
Traditional Box Sash Windows are made-to-measure, and windows are made from engineered wood and supplied fully factory glazed and spray painted with topcoat. The products are finished off with top-quality sash fasteners, lifts and pullies. The box-sash window is mainly a British commodity that is mostly found in Georgian and Victorian households. However, more recently, it has been frequently used on more modern houses to create a classic look.

Wood
Nordic Pine: Nordic pine is from a slow-grown northern forest (Siberia, Karelia). The wood is soft, medium in weight, and has medium density and excellent fibre and characteristics: tight growth rings, resulting in natural strength. Oak: The quality of oak is genuinely remarkable. Oak wood has a density of about 0.75 g/cm creating great strength and hardness. It is resistant to insect and fungal attacks and durable even in contact with moisture beyond all common beliefs. Oak is durable and long-lasting, with a bright and robust wood texture.
Sapele: Sapele is a complex and very durable hardwood. Solid Sapele is generally stable when dry, making it ideal for use in doors and windows. It is perfect for painted applications due to its fine graining. Sapele also has an attractive aroma that is resistant to insects. Siberian larch: Siberian larch timber is naturally beautiful – so no finishing is required. This tree is one of the best coniferous woods in the forest, with excellent properties.
Glazing
Sash windows are glazed with double-glazed units, incorporating advanced thermally insulating glass to provide extremely low U-values. The efficiency is further improved by filling the cavity with Argon Gas and low conductivity Warm Edge Spacer bars to minimise heat loss on the edges and result in centre pane U-values of 1.0 W/m. High light transmittance (75%+) maximises the entry of sunlight into your home. As well as our range of clear glass options,, we also have a wide choice of etched glass and extensive obscure patterned glass available in any of our windows.
All double-glazed units are designed with drainage and ventilation channels which helps to prevent timber frames from humidity using condensation grooves. Decorative bars inside glass packs – different colour profiles used for dividing glass according to required density, assembled inside the insulating glass unit.
Glass types
- Toughened – increase strength and safety
- Laminated – provides additional security over the toughened unit
- Obscure – gives privacy and style to windows
- Available in a wide range of patterns
- Security - All our box sash windows are glazed internally to improve safety, making it impossible for intruders to gain entry by removing the glass
