Retrofit in London

Overview

In this project, we embarked on a comprehensive renovation that included a complete strip-out and the addition of new extensions. By employing Passive Purple products and meticulous attention to detail, we achieved an impressive airtight score.

Background

The project began with a complete strip-out, followed by the construction of new extensions. All connections and joints were thoroughly sealed using Passive Purple Brush. This initial step is crucial for creating a continuous airtight barrier. Airtight Fleece Tape was applied around the edges to further enhance the airtightness. This tape is particularly effective in sealing difficult-to-reach areas and providing an additional layer of protection. Passive Purple Internal Vapour Control was then sprayed over the prepared surfaces, including blockwork and ceilings. This layer provides a seamless airtight and vapour control finish, essential for preventing air and moisture infiltration.

Solutions

Our approach to this project highlights the importance of detailed preparation and the use of high-performance materials to achieve exceptional airtightness. By utilizing Passive Purple Brush for initial sealing and Passive Purple Internal Vapour Control for a seamless finish, we ensured that all joints, connections, and surfaces were thoroughly protected. The application of Airtight Fleece Tape and the comprehensive treatment of the loft area further reinforced the building's airtight envelope.

Results

Achieving an airtight score of 0.3 ACH is a testament to the effectiveness of the Passive Purple products and the meticulous application process. This score significantly reduces energy consumption and enhances overall building efficiency.
