Passive Purple Airtight Vapour Control Layer - 10Kg

To make your home or building energy efficient, for insulation to perform to its optimum capacity and for a draught-free, comfortable indoors, you need to make sure that it is airtight. Airtightness refers to eliminating any gaps or cracks in the building to reduce the possibility of losing heat in order to maintain warm and comfortable indoors.  

This is where the Passive Purple vapour control layer come into play. It is a water-based vapour control layer that can be spayed or rolled on walls, ceilings and floor joints. It dries to form an airtight flexible coating that improves the energy efficiency of your home. 

It can be used to improve airtightness in joints of walls, floors and ceilings which are high-risk areas for losing heat. The liquid vapour control layer lasts longer and offers improved airtightness compared to other vapour control layers. They also have better fire resistance and fire ratings compared to paper-based vapour control membranes.

Spray-on airtightness membrane adheres perfectly to different surfaces such as concrete, brick, wood etc. This vapour control layer is BBA approved and complies with the Building regulations. It is VOC-free and does not contain any harmful gases or chemicals that can harm you or the environment.

The best part about this airtightness membrane has a Passivhaus-certified score of 0.03ach, which is truly excellent and about twenty times lower than the required 0.6ach(air change/hour). It also restricts the entry of harmful radon gases that harm your health. 

Installing the Passive Purple vapour control layer is also easy. It is a mess-free job that can be carried out by a single person quite easily. This liquid vapour control layer is easy to apply to awkward spaces or hard-to-reach spots in a building. It lasts longer and can be quickly applied which helps save on installation and labour charges. Plus you reduce the labour-intensive time-consuming works that involve stapling papers, taping up holes etc. No more fixing damaged papers!

Cleaning the equipment after installation is also easy as the vapour control layer is water-based. Airless spray devices are used to apply it to all areas of an external envelope (warm side of the insulation) of a building, including difficult connections to the floor, wall, roof, and joists. It lasts longer so you
