In fact, in addition to these two points, the sealing performance of doors and windows can not be ignored, especially in this cold winter season, door and window leakage will affect the comfort of living.
The cold winter wind not only makes passers-by walking outdoors feel extremely cold, but also makes people shiver with cold in a house with poor sealing. Don't let the cold air in, don't let the heat out. The test is the tightness of the whole window. If you want not to be hindered by the cold wind in your daily life, you should also pay attention to the sealing details of doors and windows.
The casement doors and windows of Zuo doors and windows are sealed with 3 rubber strips between the sash and the window frame;After the sash is closed and locked, the sealing strip will be pressed very tightly, and the tightening effect of doors and windows is obvious. Moreover, the cavity in the profile is easy to form an isobaric cavity, which will make the casement window sealing waterproof effect more obvious.
The locking parts of doors and windows mainly include locking points, locks, clutches, corner devices, etc. The lock hardware that has an impact on the sealing performance of doors and windows can be roughly divided into two categories: multi-lock hardware and single lock point hardware.
Lock points and lock seats are important hardware accessories in the anti-theft and anti-pry system of doors and windows. The lock point and the lock seat of the multi-lock point hardware are distributed around the door and window, when the door and window are locked, the lock point lock seat is firmly buckled together, and the hinge or sliding brace cooperates to produce a sealing compression force to form a sufficient seal between the fan and the frame.
In the process of installing doors and windows, it is common for the sealing effect of the whole window to be unreasonable because of the non-standard installation.
1) The filling material between the aluminum alloy frame and the hole is mainly cement mortar and polyurethane foaming agent, and the selection of cement mortar of poor quality will also greatly reduce the waterproof effect of doors, windows and wallsZuo doors and windows are selected with strong corrosion resistance and excellent quality neutral silicone glue and professional door and window caulking cement.
2) The treatment of sealant around the exterior wall is not rigorous. Outdoor sealing materials, generally use silicone sealant, poor quality sealant in compatibility and adhesion is not ideal, in the colloid is easy to crack after drying;The sealant with strong weather resistance, corrosion resistance and aging resistance is used for the doors and windows of Zuo Zoou, and the middle thickness is not less than 6mm when gluing.
3) Seal detection at the time of acceptance. The sealing test is mainly to see whether there is a hidden danger of air leakage and water ingress after the installation of doors and windows. During acceptance, put a piece of A4 paper in the open position, and then lock the doors and windows to see if the A4 paper can be pulled out smoothly.
4) Door and window flexibility detection. The flexibility of doors and windows mainly detects whether the door and window sash is opened, whether the opening and closing of the sliding and locking are smooth: open the front and rear sliding sash, repeatedly open and close the lock to see if it is too loose or too tight, if it is too loose, it means that there may be a problem with the sealing, and if it is too tight, it may be that there is a problem with the level of the window frame sash or the lock point, pulley, sliding brace, etc. are not debugged in place.
Life is made up of countless small things, doors and windows are made of countless materials, and Zuo Doors and Windows is committed to creating a safe and high-quality home for the owners and helping to create a more warm and comfortable home atmosphere.
