High-performance in Norwich

Overview

In our timber frame project, achieving the airtight score we did showcases the exceptional airtightness and comprehensive sealing techniques employed. Utilizing the Passive Purple product line, we ensured a robust, flexible, and durable envelope that addresses both external and internal airtightness while providing additional protection against radon gases.

Background

A coat of Passive Purple External Brush weatherproof membrane was first applied to all joints and junctions. This step is crucial for ensuring that these potential weak points are adequately sealed against water and air infiltration. The entire external surface, including connections, was coated to ensure a continuous and watertight barrier.

Solutions

The use of Passive Purple External Brush and Passive Purple Internal Vapour Control in this timber frame project exemplifies the importance of detailed sealing and preparation for achieving superior airtightness and energy efficiency. This project not only meets but exceeds industry standards, ensuring no air loss and enhanced thermal performance. The added benefit of a radon barrier further highlights the commitment to creating safe, healthy, and energy-efficient living spaces. This meticulous approach ensures long-term durability, weather resistance, and comfort for the building's occupants.

Results

Achieving an airtight score of 0.17 ACH is a remarkable accomplishment, significantly exceeding standard building requirements and demonstrating the efficacy of Passive Purple products. This level of airtightness dramatically reduces heating and cooling loads, leading to substantial energy savings and improved indoor comfort.
