Doors and Windows sealing strip and sealing strip is divided into glass wool top two kinds. Sealing strip in general use on the door to door, layering and doors and Windows have special sealing strip groove, main effect is through the layering and inner sealing strip, glass and box door closer, so as to ensure the tightness of the doors and Windows. Installation part of the sealing strip should level off, not curly, not stretching, joint should be less than 1 mm, sealing strip model should match, will make the layering pressure, starts to make the article sealing strip is easy to fall off, glass and fan is also not close together, there will be a gap. Sealing strip should choose non-toxic. Tasteless environmental protection special sealing strip. 

Galley installation part of the general fan in the doors and Windows, the sides of the box fan or seal (wind block), the bridge between frame and door seal. Wool top size is too large or vertical hair too high, not only the assembly difficulty, and make the doors and Windows mobile resistance increases, especially on the resistance and closed in place at the beginning of the resistance is bigger. Specification is too small, the vertical height of wool top not easy emergence slot, makes the sealing performance of the window (door) greatly reduced. Wool top need to the silicide processing, the quality qualified wool top appearance as the surface flat, blank and vertical hair smooth. No bend, no pitting on the negatives. Air bubbles. Arrector and blank adhesion strong, uniform density, not easy to shed. 

Doors and Windows with good tightness and water tightness, and the sound insulation? Natural to sound insulation players -- -- - insulating glass. To two or more glass, the article by aluminum alloy (filled with desiccant inside) plus bending Angle interval, around the perimeter of the glass on the edge of the butyl rubber. Polysulfide rubber; To form the stationary, dry gas, and the performance of the vacuum. Hollow glass with insulation, sealing, and frost prevention, dustproof, sound insulation, etc. Many kinds of superior performance. So many users are agreed. Excellent insulating glass should be clean inside. There is no dust. No moisture. 

Good doors and Windows is dependent on the production and installation, making the standard or not is essential to high standard doors and Windows. Production equipment and process to determine whether performance of door window whole is fine. , according to the requirement of the difference of the diagonal of the window of model steel door should be controlled within 2 -- 3 mm, with strict process parameters and control scope, this request has the certain guaranteed production equipment and technology, has the quality excellent staff team. So street shops and normal manufacturer production of window of model steel door is one day post. Third system, 7 minutes of installation, if do not pay attention to installation standards can cause deformation of doors and Windows. Model steel heat coefficient is almost just six times. So must stay between window frame and wall body expansion joint, in case of heat bilges cold shrink or housing slight subsidence distorts the doors and Windows. At the same time, in order to ensure the waterproof. Heat preservation. Sound insulation performance, the expansion joint must be filled with elastic material, and then use sealant seal. The material price is higher, the quality difference is very big, when installation should keep to cut corners and shoddy.
