The just-installed floor-to-ceiling window burst in the middle of the night, the system window worth 30,000 was leaking, and the sliding doorway was full of building garbage… This is not a horror movie, but a real car scene installed in the window! After years of hard work in the decoration industry, I have sorted out the five most deadly pits in the doors and windows to purchase and install, and after reading them, I can avoid at least 80% of the mines.

1. Material trap: Does the bridge aluminum not sound insulation? You may buy fakes!

\”The boss said it was 108 bridge ash, but in the winter, the window frame was icy!\” *Ms. Li spent 28,000 yuan of full-house windows, and the actual sound insulation effect was not as good as the original window of the developer. The \”recycled ash\” circulating on the market is 40% cheaper than the native ash, and the doors and windows processed with waste aluminum have reduced resistance to wind pressure. What\’s even more terrifying is the fake heat isolation: use PVC to impersonate PA66, and it will age and break after three years.

Avoid pits:

① Use magnetic iron to absorb the window frame, and the true bridge aluminum will not be adsorbed

② Check the profile cross-section, the original aluminum shiny is uniformly burrless

③ Fire burning is heat-free, and PA66 is not burned when it encounters fire and white smoke.

2. Fatal error: a small amount of 1 cm, and an extra 5,000 blocks are spent. The dimensions measured by the decoration team will be obtained by Mr. Zhang’s styling windows when installing them! According to a certain platform data, 65% of business owners encountered a window measurement error of more than 2 cm. What is even more pitfall is the responsibility of commercial recommendations, and additional logistics costs and processing costs are required to supplement window frames.

Secrets for accurate measurement:

① Retest three times after the tiling is finished

② Key mark beam position/pipe position

③ Photographing and retaining wall flatness certificate

3. Sealing the mill: The glue water is filled ≠ no water leakage

When the window is raining at night, it turns into a water hole? Ms. Wang is planted on a poor sealing gel. The weather resistance of the 8 yuan per piece of gangchi on the market is less than 1/3 of the professional glue. What is even more concealed is the design defect of the drainage hole: due to poor drainage of a certain website, the internal profile will be fully shined after three years.

Standard for not leaking water:

①Require the use of WACK/Dokanging brand sealing glue

② Check whether there are anti-corrosion pipes in the drain holes

③ After the rain, check the window frame and wall connections

More trickyWhat is hidden costs: the upgraded good blog handle will be 800 yuan per set.

Hardware verification guide:

① Accurate the original import identification of HOPPE (Haobo), G-U (grid house), etc.

② Check the chain load-bearing test report

③ Contract to indicate the hardware brand and model

What’s even more pitfall is the glass upgrade routine: it is standard with 5mm glass, but actually it must be 8mm to be safe.

Secrets to prevent customers from being robbed:

① Require the book to confirm the increase price list

② Beware of promotions such as \”send windows\” and \”send installations\”

③ Key verification: hollow aluminum strips/glass thickness/steelization marks
