【 Building materials network 】Measure a fan doors and windows Whether the heat preservation is ensured, mainly the door guard window Glass Whether the heat insulation strip and sealing system are stressed; To see if a window is closed tightly, what aspects should we focus on? What should we pay attention to when accepting doors and windows? This time, Suifu Doors and Windows made it clear to everyone.

1、 Sealing system ensures thermal insulation and sealing of windows

In terms of the sealing performance of doors and windows, Suifu doors and windows adopt sealant strips with better aging resistance and flexibility: more reliable sealing effect can be achieved by closely lapping with the inside and outside of the door and window frames to ensure that the doors and windows are airtight.

2、 The locking structure makes the doors and windows close more tightly

Generally speaking, the thermal insulation and sealing performance of doors and windows mainly depends on the sealant strip, while the door is the key to realize the compression between the sash and the sealant strip Window lock Close the hardware to complete.

The locking parts of doors and windows mainly include locking points, latches, actuators, corner devices, etc. The lock hardware that affects the sealing performance of doors and windows can be roughly divided into two categories: multi lock point hardware and single lock point hardware.

The lock points and lock bases of the multi lock point hardware are distributed around the doors and windows. When the doors and windows are locked, the lock points and lock bases are firmly fastened together Hinge Or the sliding support cooperates to produce a sealing compression force to form a sufficient seal between the fan and the frame. Therefore, the use of multi lock point hardware can improve the sealing and anti-theft performance of doors and windows.

It is worth mentioning that although the single locking point hardware can also meet certain pressing and sealing requirements, since the single locking point can only provide locking at the opening side of the door and window sash and the four corners of the window sash are in an unrestricted state, its sealing and anti prying effect will be worse than that of the multi locking point hardware.

3、 During installation and acceptance, the gap between doors and windows shall be checked

The main purpose of checking the functions of doors and windows (sealing and sound insulation) is to ensure the service experience and life of doors and windows in the future. First, check whether there are obvious gaps between the door and window (when closed) leaves and frames, leaves and leaves Sealing strip It shall not be loose or exposed; Check whether the door and window frames and leaves are vertical. What Suifu doors and windows want to emphasize is that whether it is flat or push-pull doors and windows, check whether they are opened smoothly, whether the surface of doors and windows is smooth and flat, whether the hardware fittings are complete, whether the location is correct, and whether the installation is firm

The flexibility of doors and windows mainly detects the opening/pushing/pulling of door and window sashes Lock Whether the opening and closing are smooth: front and rear opening/ Sliding window Check whether the lock is too loose or too tight by repeatedly opening and closing the sash. If it is too loose, there may be a problem with the sealing. If it is too tight, there may be a problem with the level of the sash or the locking point pulley , sliding bracing, etc. are not debugged in place. In case of any problem during the inspection, the seller shall be contacted in time for immediate rectification.

Installed Aluminium alloy door The window shall be tightly closed with fine and even clearance; The deviation of vertical parallelism between door and window sashes and frames, and between door and window sashes and adjacent sashes shall be reasonable. The practical inspection methods are as follows——

Inspection method 2 for door and window sealing: when the window is locked, press the four corners of the window in turn and check whether there is obvious looseness (looseness is likely to indicate poor sealing).

Every door and window is the beginning of a better life; Behind the door and window products are the persistence and persistence of our Suifu door and window craftsmen, and also the interpretation of quality life. Choose doors and windows, choose safety and choose brands: With careful door and window brands, Suifu doors and windows will naturally give you peace of mind in choosing, buying and using.
