Solar Facades

A Sunny Outlook!

Passive houses are very often fitted with south-facing facade glazing. In order satisfy these requirements in wood as well, this special facade system was developed. The Optiwin solar facade consists of a load bearing wood construction, which is covered with either wood or aluminium outside.

As with all Optiwin window systems, the outer layer serves as a protective coat and is detachable and interchangeable, allowing for flexible and individual colour designs

Advantages

• High level of prefabrication
• Fast installation
• Inner layer implemented as a statically bearing structure
• Short renovation times thanks to removable outer layer
• Wood types: fir, spruce, larch, oak can be combined for inside and outside
• Slender frame, elegant design
• Custom colour schemes for interior and exterior, natural oils, thin or thick layer glazes
• Special functions: sound insulation, sun protection and intrusion prevention
• Custom detailed planning
• Up to UW 0.72 W/m²K (U 0.6 W/m²K, U 0.69 W/m²K)
• Passive house compliant (certified by PHI in Darmstadt)

Passive house compliant

The Optiwin solar facade is based on a mullion-transom structure made of wood. The spacer between the wooden outer layer and the mullion-transom structure is thermically isolated and consists of wood and wood fibre insulation. The weight of the panels is absorbed by glass supports whose static properties have been calculated.

The Optiwin solar facade is a “passive house suitable component” certified by the Passive House Institute in Darmstadt. The prerequisite for this is a medium heat transfer coefficient (UW) for the entire construction of 0.8 W/m²K at the most.
