What are plastic steel doors and windows? Do plastic windows belong to metal doors and windows or pl

As the name suggests, plastic steel doors and windows are doors and windows that are lined with engineering plastic polyvinyl chloride (PVC) steel to increase strength. It has the appearance of aluminum alloy doors and windows, and has the strength of steel windows.

Plastic doors and windows and plastic steel doors and windows have the following differences: material, production and thermal insulation and energy saving.

First, the material

1. Plastic windows are doors and windows made of U-PVC plastic profiles. Plastic windows have good characteristics such as wind resistance, waterproofing, and heat preservation.

2. The plastic steel window is made of different raw materials polyvinyl chloride (PVC) resin, plus a certain proportion of stabilizers, colorants and fillers, as well as impact modifiers and ultraviolet absorbers, and other auxiliary agents, and finally made into molding materials.

Second, the production aspect

1. In order to enhance the rigidity of the profile, it is necessary to add reinforced steel, and such doors and windows can be called plastic doors and windows.

2. Plastic steel doors and windows are made of plastic steel profiles, which are made of plastic and steel mixed profiles.

3. Thermal insulation and energy saving

1. Plastic steel doors and windows have relatively good heat insulation performance, so the heat transfer performance is very small.

2. Plastic doors and windows have remarkable thermal insulation and thermal insulation effects, especially for modern buildings with heating and air-conditioning equipment. The ability of the impedance of a door or window to transfer heat from the high temperature side to the low temperature side when there is a temperature difference in air on both sides of the door or window.

Performance description of plastic doors and windows:

1. Wind pressure resistance: the ability of closed external doors and windows to avoid damage and dysfunction under wind pressure.

2. Water tightness: the ability of closed external doors and windows to prevent rainwater leakage under the simultaneous action of wind and rain.

3. Airtightness: the ability of closed external doors and windows to prevent air infiltration.

4. Air permeability per unit seam length: The amount of air per unit time passing through the unit seam length of the external doors and windows in the standard state, the unit is m3 m·h.

5. Thermal insulation performance: the ability of the impedance of the door or window to transfer heat from the high temperature side to the low temperature side under the condition of air temperature difference on both sides of the door or window. The thermal insulation performance of a door or window is expressed by its heat transfer coefficient or heat transfer resistance.

6. Heat transfer coefficient k0: under the condition of stable heat transfer, the temperature difference of the air on both sides of the door or window is 1k (absolute temperature), and the heat transfer through the unit area per unit time is measured as w m2·k.

1. The materials are different.

Plastic doors and windows are mainly made of plastic, which can be divided into PVC plastic doors and windows and glass fiber reinforced plastic doors and windows.

Plastic steel doors and windows use polyvinyl chloride resin as raw materials, add certain additives, and process through uncomplicated processes to make plastic steel doors and windows.

2. Different types of doors and windows.

At present, the main types of plastic steel doors and windows on the market are divided into casement windows, sliding windows, and flip casement windows; Casement windows can be said to be the most common and the most traditional type of doors and windows, and at present, the casement windows of plastic steel are mainly used in the use of floor-to-ceiling windows with a relatively large area.

Sliding windows are a popular style of doors and windows, in terms of shape and structure, sliding windows are not only fashionable and simple in appearance, but also can reduce the use of space in the house.

Originally, there was no such window type as flipping casement windows in China, but they were later introduced from Germany. In Germany, casement windows are widely used and are well received by local consumers.

3. Different brands of doors and windows.

At present, plastic steel doors and windows on the market have gradually become a material used in decoration, and there are many brands. Its products are very complex to China's environmental characteristics and consumption habits, and are known as "typical representatives of European-style plastic doors and windows in China" in terms of internal quality performance such as water tightness and air tightness.

The difference between plastic doors and windows and plastic steel doors and windows is:

1. The materials used are different. Plastic doors and windows are made of U-PVC plastic profiles; Plastic steel doors and windows are made of plastic steel profiles, which are made of a mixture of plastic and section steel.

2. Different classifications. Plastic doors and windows can be divided into PVC plastic doors and windows and glass fiber reinforced plastic doors and windows according to the material; Plastic steel doors and windows are divided into sliding doors and windows, swing doors and windows, fixed windows, folding doors, etc. according to the opening method, and are divided into ordinary doors and windows, soundproof doors and windows, and thermal insulation doors and windows according to their performance.

3. The corrosion resistance is different. The corrosion resistance of plastic windows and doors depends on the hardware chosen; Plastic steel doors and windows themselves have good corrosion resistance.

The above is about the difference between plastic doors and windows and plastic steel doors and windows.

The only difference is whether or not section steel is added in the middle of the inner cavity. Hate sticky copy party.

And plastic doors and windows? Haven't heard of it.

PVC plastic doors and windows are widely known as plastic steel doors and windows in China, plastic doors and windows are made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, impact modifiers, ultraviolet absorbers (shielding agents) and other additives, through extrusion molding materials.

By cutting, welding and other ways to make the frame sash of doors and windows, equipped with sealing strips, wool strips, hardware and other accessories to make doors and windows, in order to enhance the rigidity of the profile, more than a certain length of the profile cavity needs to add reinforced steel (steel lining), this kind of doors and windows are called plastic doors and windows.

According to the characteristics of the profile, the profile is roughly divided into two types: European style and American style.

The characteristics of European-style doors and windows are: the traditional lead salt heat stabilizer is still used in the profile formula, and a few countries and enterprises have begun to use the environmentally friendly profile organotin heat stabilizer; The main stress profile section is generally designed as three or four main chambers, and the total number of chambers reaches 6 8, and the wall thickness is generally.

The doors and windows adopt a sash frame structure, with a large fan material section and a pulley that can be removed; Interior glass, dry inlay; The window opening is mainly opened in foreign countries, and a small number of sliding windows are used.

American doors and windows: mainly use environmentally friendly organotin heat stabilizers for its formulation, which avoids the disadvantages of lead salt toxicity in the production, processing and use process; The development of multi-cavity section, the second is to reduce the wall thickness of the profile, generally; At the same time, increase the number of internal reinforced steel and chambers, and there are generally 9 13 chambers. In addition to not reducing the strength of the profile, it also improves the thermal insulation and sound insulation effect.

The sliding window is a frame-wrapped fan, which improves the sealing and safety performance, cancels the fan pulley, reduces the fan material section and improves the window lighting performance. The standard mounting method for the pull-up window and the new mounting fins was developed.

In addition, there are steel-plastic co-extrusion doors and windows in the market, which are new materials for plastic and steel mechanical compounding.

Summary. Do plastic windows belong to metal doors and windows or plastic doors and windows? Hello dear, plastic steel doors and windows belong to plastic doors and windows, which are made of PVC co-extrusion.

Plastic steel doors and windows have a good effect on heat preservation, heat insulation, environmental protection appearance and other aspects than metal doors and windows, and the price is slightly cheaper than aluminum alloy doors and windows. Introduction to plastic steel windows: Plastic steel windows are a form of windows that were actively promoted by the state in the mid-90s after wood, iron and aluminum alloy windows.

Due to its low performance and better performance, it is still widely used. Steps for the production of plastic steel doors and windows: 1. Plastic steel doors and windows are made of polyvinyl chloride, that is, PVC resin as the main raw material, 2. Add a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., 3. Extrusion molding materials, and then make door and window frame sashes by cutting, welding or screwing, 4. Equipped with sealing strips, wool strips, hardware, etc., and at the same time to enhance the rigidity of the profile, 5. The cavity of the profile exceeding a certain length needs to be filled with steel lining (reinforcing ribs), so that the portal window made is made. It is called plastic steel doors and windows.

That is, do metal doors and windows include plastic steel doors and windows?

Plastic steel doors and windows are more common types of doors and windows with inhibition function, and many families will install plastic steel doors and windows. But the owners of the first time to decorate the new house may not know much about plastic steel doors and windows, what exactly is plastic steel doors and windows? Today, PCHOUSE will answer them for you one by one.

1. Plastic steel doors and windows are made of polyvinyl chloride (UPVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., extruded into molding materials, and then made of door and window frames by cutting, welding or screwing.

2. Plastic steel doors and windows are multi-cavity structures, with good thermal insulation performance, and their heat transfer performance is very small, only 1 357 of steel and 1 250 of aluminum, which shows that plastic doors and windows have significant heat insulation and thermal insulation effects, especially for modern buildings with heating and air conditioning equipment.

3. The physical properties of PVC doors and windows mainly refer to: air permeability (air tightness), rainwater leakage (water tightness), wind pressure resistance, heat preservation and sound insulation properties of PVC plastic steel doors and windows. Because the plastic steel door and window profile has a unique multi-chamber structure, and the door and window are formed by the welding process, all the gaps are equipped with door and window sealing strips and wool strips when the plastic steel doors and windows are installed, so they have good physical properties.

Plastic steel windowsWith its practical and low advantages, it is the hottest type of window on the market, and the construction process of plastic steel windows is something that owners are more concerned about, so what is plastic steel windows? How to construct plastic steel windows? Let's follow us to find out.

The frame of the plastic steel window is made of polyvinyl chloride (PVC) resin as the main raw material, plus a certain proportion of stabilizers, colorants, fillers, ultraviolet absorbers, etc., and is extruded into the molding material; It is one of the most commonly used categories of windows in modern architecture. Plastic steel window is a form of window that was actively promoted by the state in the mid-90s after wood, iron and aluminum alloy windows. Due to its low performance and better performance, it is still widely used.

How to construct plastic steel windows?

1. Subsidize the protective film to find the center line on the frame, install the fixing piece, find the center line in the hole, adjust the entrance of the frame, temporarily fix it, connect it with the wall, fill the elastic material, clean the hole finish, install the caulking fan and glass hardware, clean it, and tear off the protective film.

2. Install the fixed piece: The fixed piece is made of galvanized steel plate with a thickness greater than or equal to the width greater than or equal to 15mm. When installing, a diameter drill bit should be used to drill holes, and then the self-tapping screw M4x20mm of the cross groove pan head should be screwed in, and it should not be directly hammered into it.

The position of the bottom of the fixed piece should be at least 150 200mm away from the window corner, the middle mullion and the middle horizontal frame, and the distance between the fixed pieces should be less than or equal to 600mm, and the fixed piece should not be directly installed on the joint of the horizontal frame or mullion.

3. Temporary fixation: when the window frame is loaded into the opening, the center line of the upper and lower frames is aligned with the center line of the hole. Then the window frame is temporarily fixed with a wooden wedge, and the verticality, horizontality and straight angle of the window frame are adjusted.

4. Fixed connection with the wall: the upper and lower frames should be fixed first, and then the frame should be fixed in a symmetrical order, and the specific requirements are as follows

1) Concrete frame building) and brick wall frame building) are reinforced with plastic expansion screws.

2) The position of the plastic expansion screw is required by the position of the fixing piece in the same strip.

3) After the window frame is fixed, cover the white plastic cover at the position of the bolt hole on the inside of the window frame, and put white sealant on the perimeter of the plastic cover to prevent rainwater from entering the window frame and corroding the steel lining.

5. Caulking: The inner cavity of the expansion joint between the door and window frame and the opening should be filled with closed-cell foam or expanded polystyrene elastic material in layers. The inside and outside of the hole and the door and window frames are smoothed with cement mortar.

Close to the hinge side, the thickness of the mortar pressing the door and window frame is limited to the opening of the partial impact sash, and after the plastering hardens, the outer side is sealed with sealant.

6. If the door and window frame is glued with cement mortar, wipe it with a wet rag before it hardens, and do not use hard materials to scrape the surface of the door and window frame.

7. Doors, windows, sashes and hardware accessories, etc., are installed after the cement mortar is hardened. When installing, first use an electric drill to punch holes, and then use self-tapping screws to screw in, and it is forbidden to beat with a hammer or hard object to prevent damage to the frame material.

The above is what is a plastic steel window for you? How to construct plastic steel windows? All of it.
