Our factory-manufactured components are designed to fit together flawlessly. We utilise advanced sealing tapes, membranes and precision-engineered floor cassettes to eliminate the gaps and cracks typically found in traditional construction methods.
We engineer our systems to achieve incredibly low air leakage rates, with capabilities of reaching as low as 1.5 air changes per hour. This level of performance is essential for developers and self-builders aiming for Passivhaus standards or strict net zero targets.
A highly airtight building requires a smart approach to fresh air. While we focus on sealing the structural envelope, our design team works with your mechanical engineers to ensure planned ventilation systems operate at maximum efficiency.
Airtightness prevents warm air from escaping and cold air from entering the building. This drastically reduces the workload on heating systems, leading to lower energy bills and a significantly smaller carbon footprint.
Airtightness is typically measured using a blower door test once the building envelope is complete. We design our frames specifically to pass these rigorous tests with flying colours.
No. We design our timber frames to “build tight and ventilate right”. By stopping uncontrolled drafts, we allow modern mechanical ventilation systems to properly manage fresh air and moisture extraction without wasting heat.
