The window is surrounded by two cm foam. Will it leak when it is filled?
Silicone weather resistant sealant, butyl rubber waterproof tape, acrylic waterproof coating + sewing polyester cloth, etc..
According to experience, only 1 years or so.
Definitely. It's better with glass glue, but just glass glue
Sure.Foaming agent is only filling material, but also need sealing waterproof material.
