Airtight & Windtight Systems

Airtightness and Widtightness are essential aspects to consider when building or renovating. Air leakage into and out of a property can be detrimental to the thermal performance of insulation. Creating an airtight seal in the property helps minimise heat loss or gain and eliminates drafts, ensuring a consistent indoor temperature. It also helps eliminate the entry of pollutants, allergens and moisture, resulting in a healthier indoor environment.
