The price of plastic doors and windows is an important issue of concern, but after understanding the price of plastic doors and windows, for the installation of knowledge, it seems that people are constantly headaches, so what are the installation standards for plastic doors and windows? Here I will lead you to understand
The price of plastic doors and windows and what related]
1, the quality of the profile
① Look at the appearance of the profile. High-quality plastic steel profiles because it contains anti-aging, anti-UV chemical composition, from the appearance, the color should be greenish white (white in green), rather than the usual white or cream; general profiles used in the south are the cavity for the three cavity structure (with closed drainage cavity and isolation cavity, enhanced cavity) profiles. If the color is too white or gray, it means that the material is not stable enough, and it is easy to age and turn yellow with time. The middle and low-grade plastic steel profiles are yellowish in white. Because the profile formula contains more calcium and has poor sunlight protection, it will become more and more yellow after a few years of use until aging, deformation and brittle cracking.
② Look at the name of the profile. Toxic plastic steel doors and windows are generally inexpensive lead salt stabilizer as the main raw material, this raw material contains lead, the name is “PVC profile”; non-toxic plastic steel doors and windows are non-toxic non-polluting, environmentally friendly requirements of thiol organic tin T-137 stabilizer, the name is “UPVC profile”.
2, profile thickness. For the plastic steel windows, there are four thicknesses of 60㎜, 80㎜, 85㎜ and 88㎜ for the windows. The thicker the profile, the higher the price. Generally speaking, 60 thick plastic steel profiles are suitable for below the sixth floor, and at least 80 thick for above the sixth floor.
3、Thickness of steel lining. In order to strengthen the plastic steel profile, there should be steel lining inside the plastic window, and the steel lining has two thicknesses of 1.2mm and 1.5mm. The national standard is 1.2㎜ thick, which is enough for ordinary household.
What are the quality standards for installation of plastic steel doors and windows?
(1) Main control items:
A. The variety, type, specification, size, opening direction, installation position, connection method and filling and sealing treatment of plastic steel doors and windows shall meet the design requirements, and the wall thickness and setting of lined reinforced steel shall meet the quality requirements of the national current product standards.
B, plastic steel doors and windows frame, subframe and fan installation must be solid. The number and location of the fixing piece or expansion bolt should be correct, and the connection should meet the design requirements. The fixing point should be 150-200mm from the window corner, horizontal frame and vertical frame, and the distance between fixing points should be no more than 600mm.
C. The specification and wall thickness of the reinforced steel lining of the molded plastic doors and windows must meet the design requirements, and the steel should fit closely with the inner cavity of the profile, and its ends must be fixed firmly with the cavity. The window frame must be tightly connected with the spelling orange material, and the distance between fixing points should be no more than 600mm.
D. Plastic steel doors and windows should be flexible, close tight, no inverted warp. Sliding doors and windows must have anti-drop measures.
E, plastic steel doors and windows accessories type, specification, quantity should meet the design requirements, installation should be solid, the location should be correct, the function should meet the requirements of use.
F, plastic steel doors and windows and the gap between the wall should be filled with closed-hole elastic material, the surface should be sealed with sealant. Sealant should be firmly bonded, the surface should be smooth, straight, no cracks.
Plastic steel doors and windows use materials that determine it has good corrosion resistance, weather resistance, fire resistance, insulation. It is not easily affected by external weather changes and remains durable after decades. And the appearance of plastic steel doors and windows is better, to meet the requirements of modern home decoration for aesthetics, and the touch is better than the metal doors and windows, so by a large number of users.
