Abstract A roof joint construction is provided which includes an insertable precompressed expansible elongated filler or core element of open cell polyurethane or the like, with an impregnant, for insertion at joints in a roof deck for engagement with the roof, the insulation on the roof and the roof deck. The filler or core is preferably held, prior to use, in a compressed condition in any desired manner, such as by a cartridge, cartridge and cap or by a vacuum packing, with interposed release sheets, if desired. Upon removal for installation the filler or core element is inserted to the desired depth at the space at the joint, and restrained against further downward movement while the expansion in the space and above the space takes place. The top of the strip may have an elastic and flexible cover thereon to protect the filler or core. Before or after the removal of the cap, if a cap is employed, the roofing covering is applied. A final roofing covering may be used over the joint, if desired.
An expansion joint for roofs and the like comprising roof panels with spaces therebetween, insulation panels superposed on said roof panels with spaces therebetween corresponding to the spaces between the roof panels, an elongate filler strip of precompressed and reexpansible cellular material with an adhesive impregnant inserted in said spaces and in sealing engagement with said roof panels and with said insulation panels and extending above said insulation panels, said insulation panel having built up roofing superposed thereon with which said strip is in sealing engagement, said strip above said roofing being flared outwardly.
