Intelligent Membranes

Passive Purple was used here on a bridge in China. Passive Purple External also comes in multiple colours form Purple to Stone colour. Passive Purple External is an anticarbonisation product that protects concrete from the effects of concrete

OverviewIn 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.BackgroundA 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.SolutionsThe 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.ResultsAchieving 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.Client Feedback''Not a radiator in site and I love it! We’re consistently warmer and more comfortable in general. Warm in the Winter and cool in the Summer. What’s not to like!''

Over view"The devil is in the detail." This phrase rings true, especially in construction projects where achieving exceptional airtightness is critical. We ensure success by starting all our projects with Passive Purple Brush, a high-performance liquid membrane that plays a pivotal role in achieving the desired air test score.BackgroundOriented Strand Board (OSB) joints are common points of air leakage. Passive Purple Brush effectively seals these joints, preventing air infiltration and ensuring a continuous airtight barrier. By sealing all critical areas with Passive Purple Brush, we achieve consistent and reliable air test scores, often surpassing stringent standards such as Passive House requirements.SolutionsStarting our projects with Passive Purple Brush is a fundamental step in achieving exceptional airtightness and energy efficiency. By meticulously sealing all connections, OSB joints, nail heads, service penetrations, and window and door reveals, we ensure that our buildings meet and often exceed desired air test scores. This attention to detail not only enhances the building's performance but also contributes to long-term sustainability and comfort.ResultsOnce applied, Passive Purple Brush forms a robust and durable membrane that remains effective over time, even with building movements and environmental changes. 0.03 ACH (air changes per hour) was achieved on this project, largely thanks to Passive Purple Brush and it’s fibre reinforced polymer technology.

OverviewIn 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.BackgroundThe 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.SolutionsOur 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.ResultsAchieving 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.Customer testimonial''My house was a vision in purple-inside and out! It really was amazing to watch. I’m definitely not dreading my energy bills anymore!''

OverviewThis project in Oxford was a retrofit, where Passive Purple Internal was applied to the outside (warm side of the insulation) of this property. An exterior insulation was fitted before a new render system was applied.BackgroundNo real difficulty with this install. The substrate was nice and sound. A render prime was put on to act as extra adhesion for our liquid applied membrane. This install took two days. Detail is always key on any project, but a retrofit can be more time consuming as there may be more gaps to fill with our Passive Purple Brush.SolutionsUsing Passive Purple to ensure all external walls are air and smoke tight before fitting external wall insulation is a critical step in modern construction practices. This approach not only enhances the building's energy efficiency and indoor air quality but also ensures compliance with stringent fire safety standards, providing a robust and reliable building envelope.ResultsThe achievement of a 0.4 ACH score underlines the potential of modern retrofitting techniques to transform existing buildings into high-performance, energy-efficient structures. As we look to the future, retrofits will play a pivotal role in addressing energy consumption, reducing carbon emissions, and enhancing the quality and sustainability of our built environment.Client testimonialsIt was a big step but once work had started i knew it was the right decision. Passive Purple is a brilliant form of technology. Why doesn’t everyone know about this?
