Foam tapes manufacturer Iso-Chemie has introduced a sealing tape aimed at the timber-frame housing market
Iso-Bloco T-Max is designed for multistorey timber-frame structures where it compensates for the large amount of differential movement – up to 36mm – that can occur between the internal timber wall and roofs and the external brick or block work.
Incorporating fire-resistant properties and slow expansion, it can be used as a perimeter seal for windows, particularly at heads, sills and under the roof eaves for both weather and airtightness, while remaining permeable to trapped water and water vapour – similar to a flexible breathable style material for the building facade.
The self-adhesive T-Max tape can be used to seal larger joints. It can accommodate a temperature range of -30°C to +90°C and is impermeable to driving rain, claims the company.
The tape can be over-painted with emulsion, and some acrylic, paints and complies with the relevant UK Building Regulations, as well as DIN EN standards, covering thermal conductivity, dimension tolerance, impermeamability to driving rain.
