Structural Glazing Tapes is the most widely used spacers for structural silicone systems. They are also known as spacer tapes, which are available in a wide variety of sizes to accommodate typical silicone joint designs. And, in addition to holding the glass or cladding at a predetermined distance from the substrate for proper silicone joint design, they also offer a number of other benefits, including compatibility with other silicone sealants, a special adhesive surface, curing of sealants, a special formulation and thermal resistance.Many brands are available in market but International Rubber Company deals with well known brand in the market which are Norton by (Saint- Gobain) & Vito from Germany, as they are well known by the faade industry.
