Adhesive tapes: how do they work, what should they be able to do, and what can they do?
Considerable lengths of various adhesive tapes are used when sealing buildings. A carpenter can be seen here sticking the interior corners of a window when working on the interior of a fire station.
Adhesive tapes are used as bonding aids in a wide range of applications in the creation of airtight building envelopes. Several hundred metres of tape are often used on a single building! Adhesive tapes have become established as bonding agents for these applications (just as nails are the standard solution for timber structures). They have to fulfil their functions for a number of decades to ensure that the building in question fulfils the standards expected by the energy consultant and by the building client. This article provides an overview of adhesive technology and the key properties of adhesive tapes typically used in construction.Continue reading →
The airproofing layer protects the insulation from moisture and condensation from the inside, ensures that the insulation works effectively and provides a healthy indoor living environment.
The thermal insulation separates the indoor from the outdoor climate. The temperature difference between the two climates attempts to become equalised through the flow of air. This means in winter the warm air from the building transfers through the structural elements to the outside. The airproofing layer prevents this air flow, the so-called convection, and therefore the loss of hot air to the outside. The interior space is here not hermetically sealed off – like using a plastic bag – from the outside air. Instead, the exchange of air from the inside to the outside continues via diffusion.
