Installation Instructions of UPVC Windows and Doors

1. Installation of Window and Door Frame
There are two installation methods which are described below.
1) Open holes on UPVC window frame, plastic expansion installation method
Installation of window and door frames can be started after fixing three-side window cover and lower window board. The position of window and door frames can be adjusted and temporarily fixed by wedge, pad or other apparatus. Be careful not to make the profiles deform or damage. After fixing the window and door frame, wedge or pad should be removed immediately.

a) The gap between window frame and window cover should not exceed 5mm in order to ensure quality of gluing.
b) Adjust the frame in place and connect it with window cover and window board by plastic expansion screws.
c) The distance between fixed plate and corner of the frame should be less than 150 mm, and distance between two fixed plates should not exceed 500 mm.
d) Vesicant is adopted to complete caulking in upper, left and right sides of the window frame. It should be sprayed from outside in order to ensure the flatness of the vesicant surface. Reduce the adjustment of vesicant and make sure there is no leakage.
e) Hard plastic pad is adopted to fill the crack in the lower part of the frame.
f) Neutral silicone sealant is used in the edges of the frame and waterproofing treatment is required.

(2) Open hole on window board, stainless steel screw installation method
The window frame and board are firstly connected and then mounted into the window holes.
a) The distance between fixed plate and corner of the frame should be no more than 150 mm, and distance between two fixed plates should not exceed 500 mm.
b) Vesicant used to conduct caulking in left, right and upper sides of the window frame should be sprayed from outside, ensuring the flatness of the vesicant surface. Minimize the adjustment of vesicant and make sure there is no leakage.

d) Hardware accessories should be installed correctly, ensuring normal opening, water tightness and air tightness.

3. Protection of the Finished Product
There are several methods of protecting the finished product during the installation process.
a) Stick protective film on surface of the profile and hardware
b) Put U-shaped wooden protective shell in the lower threshold of the window and door frame
Note: The second installation method is recommended when the installation is conducted in wooden houses.
