Curtain Wall Caulking – After a long flight and hours at baggage claim, most people just want to get to their hotel and relax. A leaky window can create multiple issues for the building and its guests. If the problems are bad enough it could cause rooms to be refunded and cost the Hotel hundreds if not thousands in both rooms lost and structural damage. This particular job was important for just that reason. The Hilton at LAX received a complete exterior caulking of the tower curtain wall system to create a weatherproof seal on the building and prevent leaks from becoming a major issue. For this job, we used a new professional grade silicone sealant for all exterior glass-to-metal joints. In order to eliminate all water from entering the curtain wall system the metal-to-metal window mullion splice joints and the bolt penetrations along the swing-stage tracks were also sealed with the same silicone. This creates a strong seal that will help keep the building and its guests nice and dry during their stay.
