Airtight seals against water, air, wind, vapour and noise Gaps which open up as a result of a discontinuity in a roof and/or an unsealed wall can give rise to the following problems: • Ingress of heat in the summer • Loss of heat in winter due to natural convection of warm air and the ingress of cold air from the outside • Condensation in the outer layers in winter, where warm air coming from inside the building cools down and may condense Possible discontinuities in the roof and/or wall • Condensation in the inner layers in winter, where humid air outside cools down and may condense •...

The problems caused by impermeability to air in roofs and wooden walls Air permeability describes the manner and quantity of air passing through a building element. This concept must not be confused with vapour diffusion, a useful phenomenon, when seeking to dry a roof. The free passage of air actually gives rise to serious problems in terms of heat and condensation. Vapour passes through open gaps in the direction of the passage of heat: in winter this is from inside the building to outside, and vice-versa in the summer, from outside to inside. Humidity condenses at a lower temperature...

How to guarantee a good air seal A good air seal on a roof or a wooden wall can be achieved by ensuring a synthesis between design and execution and by trying to ensure that there are two airtight layers present: • internal airtight layer (for example a vapour barrier) • external windtight layer (for example a highly breathable membrane) The weak points are not large surfaces but all the discontinuities and openings in the roof such as conduits, pipes and ducts. Watch out for Lifeline system rods, aerials, ventilation pipes, pipes for solar and photovoltaic systems, and to exterior lamps,...

Guide to adhesive tape Adhesive tape is a tape with a non-adhesive side and a pressure sensitive adhesive on the other side. This adhesive is effective at ambient temperature and does not need to be activated (by water, temperature, etc.). The adhesive tape is applied directly to surfaces using a little pressure. Self-adhesive tape: the adhesive is present only on one side of the tape. Bi-adhesive tape: a self-adhesive tape where the adhesive is present on both sides. This tape is also applied by pressing slightly due to the characteristics of the adhesive mass. Main types of support...

Methods of storage - duration and environmental conditions: the adhesive tapes normally retain their performance characteristics for a period of no less than 12 months, unless otherwise indicated by the manufacturer. During this time, the storage temperature should remain between 15 and 25 degrees centigrade, with relative humidity preferably no higher than 65%. It is also recommended to avoid direct exposure to light and heat sources. Products which may have been stored at temperatures below those recommended must be reconditioned before use, i.e. they should be brought to the recommended...

Advanced version - USB Tape 1 PAP X: the more advanced version of this adhesive tape is USB Tape 1 PAP X which has a protective silicone liner cut in half lengthwise; this development makes it easier and quicker to seal the internal corner joins of panel walls and OSB boards; in fact, with the full liner, it would be quite difficult to seal corners without the adhesive tape sticking awkwardly before being able to press firmly on the two opposing surfaces of the panels. Application: identify all surfaces to be bonded, make sure that they are dry and free from dust and grease (alternatively,...
