Airtightness installation is becoming more and more important in modern methods of construction. Even in modern buildings, a significant amount of heat is lost through air leaks.
This is why here at Intelligent Membranes we take great pride in providing innovative airtightness solutions that comply with the latest international standards for sustainability in construction.
Our Passive Purple range is used by many airtightness installers and builders around the world as a more eco-friendly way to ensure breathability and airtightness in new and existing buildings.
In this airtightness installers guide we’ll help you better understand the importance of airtightness membranes in modern construction and where you should be using the Intelligent Membranes products range.
Why is Airtightness Important?
As building methods progress to a future of sustainability, more emphasis is placed on energy efficiency and controlling air leakages in buildings. The regulations and requirements around the energy performance of buildings continue to become more and more demanding.
Air leakage from the building’s structure can lead to heat loss through convection, which is why airtightness is an absolutely necessary element in modern construction practices.
This is where our Passive Purple airtightness liquid membrane can help. Our range of air tightness membrane products will provide an effective solution, while keeping a building breathable to protect against mould and moisture.
How to Install Our Airtight Membranes
Due to their liquid state our products allow for easy and even airtight membrane installation. Our airtightness products can be easily applied with a paintbrush or roller, or alternatively they can be sprayed on your walls, floors or ceilings.
Passive Purple can be installed on buildings that are still under construction as well as existing properties. Whether you want a building to be protected from day one, or wish to improve airtightness in an older building, it’s easy to achieve the wanted results.
During the airtight membrane installation, particular attention should be paid to the following parts of your building:
- Wall/Ceiling Connections
Wall and ceiling connections are one of the areas in your building where airtightness is crucial, especially where the connections are made of two different types of materials for example brick and concrete or structural steel and concrete. Construction materials react differently to changes in humidity and temperature, which can lead to cracks in the plaster or other type of finishing used. Even the tiniest cracks can create air leaks and lead to heat loss and significant decrease in your building’s energy efficiency. With our Passive Purple Joist Seal you can make sure any connections between walls and ceilings are properly sealed so no heat can escape through .
- Envelope Penetrations
Service penetrations can negatively affect air tightness in buildings. Our Passive Purple Brush Facade membrane can be applied around objects that penetrate the building’s surface to the external envelope, sealing where most other membranes fail.
To install Passive Purple Brush, first apply polyurethane foam around any penetrations. After hardening, remove the excess foam and apply a generous amount of Passive Purple with a flat paintbrush. In all cases, apply a sufficient, well-covering layer to guarantee airtightness.
- Windows/Doors
Windows and door reveals that aren’t property insulated and made airtight can cause a substantial loss of heat in homes. Our Passive Purple Brush is designed to help with that by sealing any gaps between the frame and the wall. It can be applied on different materials including concrete, wood, brick, PVC, aluminium or polyurethane foam.
