Our spring sash windows
are glazed with double-glazed units which incorporate an 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 minimize heat loss on the edges and result in center pane U-values of 1.0 W/m.
High light transmittance (75%+) maximizes the entry of sunlight into your home. There is a wide choice of clear glass options, etched glass, and extensive obscure patterned glass.
To improve security, all our spring sash windows are glazed internally, which makes it impossible for intruders to gain entry by removing the glass.
All double-glazed units are designed with drainage and ventilation channels, which helps to prevent timber frames from humidity using condensation grooves.
Decorative glazing bars
Decorative bars inside of glass packs – different color profiles used for dividing glass according to required density, assembled inside of insulating glass units.
- Toughened – increase strength and safety.
- Laminated – provides additional security over toughened units.
- Obscure – gives privacy and style to windows.
