Effisus Sealexpand
Permanent Joint Sealing for Facades / Water Tightness, Thermal and Acoustic Insulation
Facade joints, such as joints between cladding panels or around windows and doors, are often sealed to avoid water ingress, heat loss and promote acoustic insulation. Effisus SealExpand XTRA foam tape has outstanding expansion sealing and adapting to the gap and its movements.
Prefabricated construction in concrete or other materials
Perimeter sealing of frames
Cladding panels
Façade joints, namely between cladding panels or around windows/doors, are often sealed to avoid water ingress, heat loss and promote acoustic insulation.
Effisus Sealexpand XTRA foam tape delivers exceptional expansion capacity, adapting to irregular gap shapes and accommodating joint movements with lasting elasticity. This ensures durable watertightness along with reliable thermal and acoustic performance. Resistant to UV exposure and direct rain, it acts as a standalone sealing system that is quick to install, maintenance-free, and suitable for various construction methods, including general building, timber or steel frames, and modular projects, both new and refurbished.
Moreover, Effisus Sealexpand XTRA is also used to close off the end of roofing sheets, as an alternative to profiled foam fillers, and thus seals these edges on metal roofs.
For cases of demanding façade interfaces with more demanding requirements, such as extreme elongation and fire resistance ability, Effisus ProFlex FR high-performance weatherproofing membrane would be a perfect fit.
