Seal doors and windows sealed plastic strips into glass tops and two kinds. Seal tape is generally used in fan windows and doors, windows and doors on the layering has a dedicated sealing strip groove, the main role is through the bead and inner fan wearing a sealing strip, so that the glass box and fan closer, thus ensuring doors and windows tightness. Installation site seal strips should be smooth, without curl can not be stretched, the joint should be less than 1mm, the model should match the sealing strip, so that the pressure of the pressure over the General Assembly does not go too small to make the seal tape off easily, glass and the fan body is not tight, there will be gaps. Sealing tape should be used non-toxic. Tasteless green special sealing strip.

       Installation position on the tops of doors and general fan, box fan or seal all around the bridge (wind block), the enhanced sealing frame between the fan. Specifications tops too large or hair shaft is too high, not only difficult to assemble, and to make your Windows Mobile resistance increases, especially the larger open initial resistance and resistance to closure in place. Size is too small, vertical tops high enough easy-out outside the tank, so that (door) window sealing performance greatly reduced. Tops need to siliconized, acceptable quality exterior surface flat tops, smooth hair shaft and bottom plate. No bending, no pitting on the bottom plate. bubble. Hair shaft and bottom plate bonding firm, uniform coarseness, easy to hair loss.

       With excellent sealing doors and watertight, that does sound to sound natural players -? Insulating glass. The two or more than two of glass, plus the corner columns by aluminum gutter (which is filled with desiccant) intervals around the edge of the glass are marked with butyl rubber. Polysulfide rubber; to form a stationary, dry gas, and the vacuum performance. Hollow glass insulation, sealing, anti-frost, dust and noise and so on. A variety of superior performance. So many users are more accepted. Excellent insulating glass should be clean inside. No dust. No moisture.

       Good production and installation of windows and doors can not be separated, standard production or not of a high standard windows essential. Production equipment and technology determine whether the excellent overall performance of windows and doors. As requested, the difference between the steel doors and windows of the diagonal should be controlled within 2 - 3 mm, and strict control of process parameters, which requires a certain degree of production equipment and technology to do that have excellent quality of the workforce . So street workshops and regular manufacturers of steel doors and windows simply do not have the enamel day. Third of production, seven installation, if not pay attention to the installation standards can cause deformation of the doors and windows. Steel thermal coefficient is almost just six times. So between the frame and the wall must remain joints to prevent thermal expansion and contraction, or minor settlement houses, windows and doors so that deformation. Meanwhile, to ensure waterproof. Insulation. Sound insulation, expansion joints must be filled with an elastic material and sealed with sealant. These materials are more expensive, the quality varies greatly, and cut corners to prevent shoddy installation.
