joint design:
the specified sealant bead size should be calculated to comply with the compression and
extension capabilities of the sealant in relation to the anticipated joint width due to
expansion and contraction.
sealant widthshould never be less thansealant depth.
generally calculation of the width of pu sealant bead should be computed on the basis of
wide movement accommodation of ± 25%.
compression and extension capability minimum bead size should not less than 3mm to
accommodate movement.design joint depth of which ratio width becomes 0.5to 1.
joint depth maximun 15mm.
