Window introduction:
It is one of the building structures. The opening form of window sash should be convenient, safe and easy to clean. High-rise buildings should adopt sliding windows and internal windows, and measures should be taken to strengthen the window sash when using external windows. The height from the window sash opening to the bottom of the public walkway should not be less than 2m, and protective measures should be taken when the window sill is less than 0.8m.
The function of windows is not only to see the scenery outside, but also to a great extent to determine the quality of our life. But sometimes, many problems are not noticed at all.
Home is our residence, a relatively independent small environment created by ourselves, which provides shelter from wind and rain, wind and rain, and is not affected by any external factors. It is relatively independent because we can't live alone completely out of the external environment. We need a reasonable indoor and outdoor communication.
In this small environment, we need to have suitable temperature, humidity, air and light, as well as a sound environment suitable for ourselves. We need windows to let the light in, so that the extra heat will come in with the sunshine.
We need windows to ventilate, so dust and mosquitoes may come with the circulating air. Problems often come with your needs, so don't be careless about your window.
Introduction of plastic steel window:
Plastic-steel windows are developed from wooden windows, steel windows and aluminum alloy windows in recent years. It has the advantages of saving energy and steel, corrosion resistance, sound insulation, good sealing, flexible opening, convenient cleaning and strong decoration, and is the fourth generation of new doors and windows.
It is obviously different from ordinary plastic products. It is based on the mixed resin of polyvinyl chloride (PVC) and chlorinated polyethylene (CPE), with a certain proportion of additives, and processed into profiles by extrusion. Then through cutting, drilling, welding and other methods, make window frames and install hardware accessories.
In order to increase the rigidity of the profile, the inner cavity of the plastic profile is filled with steel lining (reinforcing ribs) to increase the tension and bending effect, which is called plastic steel window. Because it not only has the characteristics of plastic products, but also has greatly improved physical and chemical properties and anti-aging ability.
It not only has the basic functions of windows, but also can be compared with aluminum alloy doors and windows in decoration. It has the characteristics of heat preservation and insulation, making the room more comfortable, quiet and modern. In addition, it has the advantages of acid resistance, alkali resistance, corrosion resistance, dustproof, flame retardant and self-extinguishing, high strength, no deformation, harmonious tone and so on.
There is no need to use partial paint during installation, so it is durable, and its air tightness and water tightness are 2-5 times greater than those of ordinary similar doors and windows. According to experts' calculation, if plastic doors and windows are used in 0/5% of houses in north China, coal140,000 tons, electricity130,000 kWh and steel 65,000 tons can be saved.
