Building envelope expansion joints

When sealing the building envelope, using a quality façade sealant is essential. Sealing around windows (window frame to brickwork) and between concrete or façade panels are the most common applications.

Joint sealant is intended to prevent moisture, air or dirt from penetrating the structure of a building. Various elements of a structure can move due to temperature fluctuations, the wind, etc. To be able to adapt to this movement, façade sealants must be highly elastic. Good adhesion to concrete, aluminium panels and various window frame materials (wood, PVC, coated aluminium) is also important. Flexifoam can be used behind the sealant for good, lasting insulation between moving structural elements.
