Windows installation problems must pay attention to four aspects when installing
At the time of installation, the industry pays special attention to the following aspects. 1. Is the window frame erected? When the worker puts the window frame on the opening at the installation site, he should flatten the window frame, and measure the horizontal, vertical, and diagonal lines of the window frame with tools such as a ruler, a ruler, and a hammer to confirm that the frame is placed properly. The next step is fixed. 2. Do not tighten the bolt once When installing, hit the expansion bolts or tabs around the windows. During this process, some workers like to fasten the fasteners such as the expansion bolts one by one. This will deform the already adjusted window frames. Renovation of the first network suggested that the correct approach is to tighten the expansion bolt to be symmetrically screwed, but do not tighten it once, this will ensure that the adjusted window frame evenly without deformation. 3, check the window security After the window frame is connected to the window opening, check whether the window frame is installed again before installing the glass. If the windows are not installed properly, the performance of the windows will be affected. 4, inside and outside the sealant must play For the already fixed windows, the next step is to fight styrofoam and sealant. Styrofoam is used to fill the gap between the window frame and the wall, it can not be exposed for a long time, otherwise it will become aging "crisp." So be sure to use sealant on the inside and outside of the window frame. The above points are due to some workers will ignore, the owner needs to stare and remind.

PVC capillary Drainage Board is made of laminated soft rubber material, and the dense slot is opened on soft rubber plastic material. The slot hole is designed to be small inside and big outside and when you use it you should let the hole facing down. Using the principle of capillary water absorption, the water flow is poured from the bottom up to the capillary sink. The soil particles in the water will naturally precipitated by gravity, and the soil particles will not enter into the capillary water pipe, and will not generate siltation near the water channel. PVC Drain Board can produce excellent water absorption and drainage.
Product features
1. Non-blocking: use of natural gravity to separate soil and water;
2. High permeability property: 20% open hole rate has effective water absorption area;
3. High drainage efficiency: drainage board using capillary force to improve drainage efficiency;
4. Strong anti-earth pressure: arch bridge structure design, effective dispersion of stress distribution with self-cleaning function,
5. Convenient construction: the drum package will not take up the volume and reduce the transportation cost, storage, management, work cost
7. Flexibly: can be closely combined with the topography to form an infinite long, compressed highway;
8. Durability: Stoma Drainage Plate made from PVC high density polymerization material, so PVC drain board has the advantage of uv resistance and durable.

In principle, the hole groove (absorbent surface) can be roughly downward, so that the soil particles can be settled by gravity to prevent blockage.
At least two percent of the embedding slope are recommended to generate siphon-age
