Airtightness
A vital component in ensuring an energy efficient home
Only when a construction is airtight can warm air be retained within and cold air kept outside. Preventing unpleasant draughts means greater living comfort and increased energy efficiency, which in turn leads to lower heating cost.
Airtightness also protects the building fabric against damage, helping to maintain its appearance and extending the buildings life.
How to achieve airtightness and why?
Airtightness simply means eradicating all drafts. Drafts can be so small e.g. under window boards, around windows and doors but an accumulation can have a drastic impact on the energy loss in the dwelling and lead to significant discomfort and high running costs.
The only way to achieve Airtightness is a consistent air-resistant layer all around the inside of the building. This includes the area where the wall/floor meet, around the door and window openings.
A layer of breathable membrane behind the plaster slab on the upper ceiling, regardless of the structure type, timber frame or masonry construction the air tightness layer must be continuous from floor to ceiling.
The wind tightness tapes can be used with all suitable breathable roofing and facade membranes. The tapes and adhesives are free from residential toxins such as solvents (VOC), high boilers, formaldehyde, chlorine, plasticizers.
