Passive House Timber and Aluminium Clad Windows
Schnauber manufactures high performance Passive House timber windows and Passive House aluminium clad windows designed to meet the energy performance requirements of the Passivhaus Institute. All systems are engineered to achieve U values of 0.8 W per m2K or lower.
These windows are designed to support low energy building envelopes by reducing heat loss and maintaining consistent internal comfort. Systems are suitable for certified Passive House projects and high performance residential and commercial buildings.
Passive House aluminium clad windows feature an insulated timber core with a durable external aluminium layer, providing long term weather protection and reduced maintenance while maintaining high thermal performance.
Glazing and Thermal Performance
Glazing systems are engineered to minimise heat transfer and eliminate thermal bridging. Triple glazing with insulated internal cores is supplied as standard to meet Passive House performance targets.
Argon or krypton gas filled units and low emissivity coatings ensure stable internal surface temperatures and improved winter performance.
Vacuum glazing can be specified where very low U values are required within slim glazing profiles. This option is suitable for retrofit projects, design constrained buildings and applications requiring maximum thermal efficiency.
Precision Craftsmanship and Specification
Schnauber Passive House windows are manufactured using advanced German engineering processes to ensure dimensional accuracy, structural integrity and long service life. Each unit is produced to strict tolerances to support certified performance.
All windows can be fully customised including frame construction, glazing specification, finishes, RAL colours and hardware options. Performance values are verified through testing to ensure airtightness, thermal efficiency and weather resistance meet project requirements.
Schnauber is FENSA registered, ensuring all installations comply with current building regulations and recognised industry standards.
