OKAWOOD® Insulating Glass with Timber Grid
Only a few selected types of domestic and exotic wood are suitable for integration in the cavity. Every batch of incoming wood is individually tested by an outside institute for properties such as density, UV stability, other key material properties. The glass protects the timber inserts from the effects of weathering and allows the wood to retain its elegant, original appearance. Special requirements for transparency and light transmission can be realized by adjusting the spacing of the louvers within the unit.
Depending on the gas filling and coating, a 2-pane OKAWOOD® Grille make-up achieves U-Values between 0.23 – 0.33 Btu/(hr./ft²/°F) . As a 3-pane make-up, U-Values range between 0.11 – 0.18 Btu/(hr./ft²/°F).
Wood is fixed as a grid in the inner space between the panes. The horizontal wooden bars are 3/8″ (10 mm) in height. The product documentation of OKAWOOD® includes detailed, angle-dependent light transmission and SHGC. The transmission of OKAWOOD® insulated glass with timber grille is variable, allowing the lowest amount of incoming heat and glare in the summer months while providing a gain of solar heat in the winter when this makes the building interior more comfortable and efficient.
The wood used within OKAWOOD® is natural and saw cut. No stains, oils or paints are used on the wood surfaces.
