Services
Airtightness Systems
Our airtightness systems create continuous barriers against air leakage in residential and commercial buildings. These solutions prevent heat loss, reduce energy bills, and maintain indoor air quality by blocking moisture ingress. Compliant with NZEB standards, they integrate seamlessly with various construction types.
Weathertightness Membranes
Designed to withstand harsh external conditions, our weathertightness membranes form waterproof barriers while allowing vapour diffusion. They protect building structures from wind-driven rain and improve thermal efficiency in roofs, walls, and facades across multiple construction methods.
Insulation Products
Our insulation range includes rock wool and foam boards that enhance energy efficiency through superior thermal resistance. These materials reduce heat transfer, control condensation, and provide acoustic benefits while maintaining fire safety and moisture resistance in diverse applications.
Window Sealing Systems
The QWS window sealing system combines airtightness, weathertightness, and insulation in one comprehensive solution. It prevents draughts, blocks moisture ingress, and improves thermal performance at window and door junctions while maintaining structural integrity.
Installer Training
Our certified training programs teach professionals to identify air leakage points and apply airtightness materials correctly. Participants gain practical experience with membranes, sealants, and testing procedures to achieve compliance with modern building regulations and performance standards.
Questions
