Abstract
This disclosure is concerned with improvements in, or to methods for, weather sealing between adjacent building elements used in building construction. The building elements may include but are not restricted to silicone structural glazing units (SSGs), insulating glazing units (IGUs), monolithic transparent panels, and laminated transparent units. The building elements may be utilised in either exterior and/or interior building applications such as, for the sake of example, curtain wall facades, glass surfaces, cable net façades, shop fronts, skylights, conservatories and the like.
Claims16
A method of weather sealing a cavity having a pre-defined nominal joint size, formed between a planar surface of a first building element which is transparent and a planar surface of an adjacent second building element which is facing the planar surface of the first building element and which is optionally at least partially transparent, the method comprising the steps of:
- (i) applying a coating of a one component, translucent silicone sealant composition on the planar surface of either the first or second building element;
- (ii) applying a coating of a one component, translucent silicone sealant composition on the planar surface of the other of the first or second building element;
- (iii) inserting a pre-cured strip of a transparent silicone weather seal material having a circular or oval cross-section with a diameter of from 110% to 150% of the pre-defined nominal joint size between the planar surface of the first building element which is transparent and the planar surface of the adjacent second building element which is optionally at least partially transparent facing each other;
- (iv) removing any excess one component, translucent silicone sealant composition applied in step (i) or step (ii) subsequent to step (iii);
- and
- (v) allowing or enabling the remaining one component, translucent silicone sealant composition to cure and form a weather seal by adhering the pre-cured strip of a transparent silicone weather seal material inserted in step (iii) to both the first and second building elements.
