High density Aesthetically pleasing to the eye; warm colors from golden brown to yellow sand, orange in the heartwood.
- Our IV78 windows are glazed with double-glazed units which incorporate 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.
