Passive House Systems supply a comprehensive range of fully supported Airtightness and Weathertightness systems that protect the building envelope, meet NZEB standards and are compliant with building regulations.

Vapour Control

Moisture in buildings causes damp, mould and rot, which can impact the structure of the building as well as our immune systems. By installing suitable airtightness systems in your home, interstitial condensation can be controlled and the growth of mould and mildew prevented.

Energy Efficiency

Future proofing our buildings enables them to depend less on energy consumption and rely more on high performance building materials, that reduce draughts and heat loss, improve thermal performance and enhance insulation to increase building energy efficiency.

Building Protection

Using airtightness and weathertightness principles in the construction of a building ensures structural protection against harsh weather externally and air leakage, condensation and dampness internally, while also preserving the building structure and improving longevity.

Indoor Air Quality

Poor indoor air quality is a risk to health, so creating an airtight building envelope to prevent moisture from entering the structure is fundamental in modern building practice. Without airtightness the effect of the building insulation is reduced and mould forms diminishing air quality.

Premium Calibre

Passive House Systems range of products are especially formulated and designed with purpose and application in mind. Our products follow strict manufacturing conformance and quality standards, and are fully supported by associated documentation and technical advice.

QWS – Quality Window Sealing, combines the three core elements required for thorough sealing of window and door reveals: Weathertightness, Insulation and Airtightness.

Weathertight

The exterior Weathertight layer is waterproof to block wind and driving rain, while also enabling the expulsion of vapour.

Insulating

The Insulation layer improves thermal performance and acoustic insulation.

Airtight

The Airtightness layer controls the movement of internal air and vapour from infiltrating the window connection joint.
