A bonding step in a method of producing a bonded body includes a first bonding step of forming a sealing layer (4) by irradiating a sealing material (6) belonging to an inner group (IG) with a laser beam (L), and a second bonding step of forming a sealing layer (4) by irradiating a sealing material (6) belonging to an outer group (OG) with the laser beam (L) after the first bonding step.

Provided is a pre-applied waterproofing membrane having a waterproofing adhesive layer and an outer particle layer comprising synthetic polymer granules to protect the adhesive layer and to facilitate detailing at membrane-to-membrane overlaps. In preferred embodiments, the synthetic polymer granules are made from polymers selected from the group consisting of polyvinyl acetate, acrylic, and styrene butadiene copolymers or polymers. Most preferably, the synthetic polymer granules have round or spherical shapes that help to facilitate detailing at the building or installation site, such as sealing at membrane overlaps, and sealing around pipes or other details. Alternatively, the membranes may be made having side edges which are free of synthetic polymer granules, whereby a removable release liner strip can be used to prevent adhesive from sticking to the back of the membrane when the membrane is rolled up on itself for shipment.

A vacuum insulating panel may include: a first glass substrate; a second glass substrate; a plurality of spacers provided in a gap between at least the first and second substrates, wherein the gap is at a pressure less than atmospheric pressure; and a seal having at least one layer provided between at least the first and second substrates. Additive(s) may be provided in material(s) for the seal in in order to improve thermal diffusivity and/or thermal conductivity thereof.
