| 02-23-2012 |
| 20110309584 | SEALANT STRIP AND METHOD OF FORMING LAP JOINTS - The present invention relates to a form of lap joint for forming a water-tight joint between sheet materials comprising a sealant strip between 2 sheets of material, the sheets of material being held about the sealant strip by means of a plurality of fasteners. The sealant strip comprises a pliable sealant material in which is embedded, along the length of the strip, one or more elastomeric cords. The invention provides an improved form of construction such that sealant in a non-hardened form, such as before setting or when of a non-setting form is not extruded from a joint overtime and thus the integrity of the joint is maintained. | 12-22-2011 |
