Airtightness for Thin Internal Wall Insulation Systems
This approach saves on both the labour and material costs associated with achieving the energy efficiency demands in buildings. The Wraptite® system is not just for external use however, and this webinar considers it's use as part of an airtight, energy efficient thin internal wall insulation build-up.

PDF Retrofit Internal Wall Insulation
The risk of interstitial condensation with internal wall insulation can be high due to warm internal air passing through or around the insulation and airtightness layers and condensing on the cold wall , and/or from external moisture within the masonry.
Airtight Vapour Control Layer for use within the internal lining of roof, ceiling and wall systems DuPontTM AirGuard® A2 FR AVCL: a Fire Retardant Airtight Vapour Control Layer for use within the internal lining of roof, ceiling and wall systems .

Moisture damage and biological degradation are common symptoms where the use of conventional internal insulation systems with vapour barriers and non breathing systems are used. PAVATEX ISOLAIR wood fibre insulation board, has been especially designed for internal insulation of the exterior walls on old and historic buildings.
Achieving airtightness in buildings requires architects, buildings, and developers to incorporate innovative methods and materials, like StoTherm® ci cladding systems . An energy-efficient, code-compliant, durable, and attractive StoTherm® ci Wall System is a superior wall solution for achieving airtightness in buildings.
Airtightness Installation Guide
Installing one of the DuPont™ AirGuard® AVCL membranes will keep your insulation and wall structure dry and can help to reduce energy consumption. On top of choosing the right AVCL it is important to make your building envelope airtight and windtight by sealing gaps between and around insulation layers, AVCL's and breather membranes.
Normally expansion joints are sealed for airtightness using flexible airtightness tapes installed such that they have a "bellows" to allow for relative movement between adjoining sections of wall or floor.
Air Barrier Materials
Air Barrier Types and Airtightness Strategies Air barriers can be either external or interior to the wall assembly. In some cases, the building may have two air barrier layers, with some even performing double duty as a water control layer. The typical external air barrier types include: Mechanically adhered sheet membranes Self-adhered membranes
Airtightness , insulation , and ventilation are important considerations when building a home. Not ventilating properly on any home can lead to a poor indoor air environment, which encourages the growth of mould.
