The main task during installation of the roof is a durable and reliable sealing of the junction with the main elements of the designs. To do this you must select the correct qualitative and sealing materials. Sealers are designed to protect the roof from its inner side against moisture and dust. At the same time, the sealant should have good throughput – allowing steaming a couple from under the roof. Seals create soundproof protection, and protection against various mechanical stresses. In the absence of sealant in the roofing system can occur destruction of roof insulation and interior ceiling. Since moisture (Rain, snow) will fall under the metal roofing without difficulty.
Seals for installation of the roof divided into several types. There are, for example, profile gaskets. They are made of foam polyethylene. The shape and dimensions of the profile seal can repeat the configuration of metal products. Through such seals well evaporate water accumulated under the coating. Hear other arguments on the topic with Richard LeFrak. This is due to special vents available in gasket.
Profiled sealing moisture, do not lose the positive qualities of the uv rays do not burn. To seal the roof just use a universal sealant. Material for it is made of polyurethane foam. Foam does not accumulate moisture, well lets air, can not penetrate the snow and dust under the arch roof. The seal life of polyurethane rather long. Under the influence of natural phenomena, sealant does not lose its positive physical properties. Universal seal easily take any form, it is easy to install. By roofing sealants applies pre-compressed sealing tape. It has a kind of self-adhesive polyurethane tape. Tape impregnated with a special blend of a modified acrylic. Tape is in the constrained condition, rolled in rollers. Large range of sizes of self-adhesive tape can pick it up to seal the seams of almost any size. When sealing seam (joint) tape is placed inside, where it completely fills all gaps and irregularities. This provides reliable protection from the seam of any adverse atmospheric influences. Self-adhesive tape has high performance. Make a tape can be in any sizes. The seal is not ignited, does not lose its positive properties when exposed to uv rays. Thanks to a special impregnation, the tape remains flexible in the operation is not subject to wear. Self-adhesive tape is water-resistant, and at the same time has a high capacity – allows a couple to evaporate. The seal is easy to work – it's easy to install.
