Fireproof window refers to the window composed of steel window frame, steel window sash and fireproof glass, which can isolate and prevent the spread of fire. Plastic steel windows are also common windows used in buildings in our lives. So, do you know the differences between fireproof windows and plastic steel windows? Which is better? I have made a detailed summary for you today. Let's take a look.

1、 Different window materials

1. General fireproof windows are made of steel, plastic steel, aluminum alloy, wood, etc. The sealing material between the fireproof window, frame and fireproof glass shall be fire-resistant material, and the hardware fittings shall be the approved supporting products that have passed the test, which can play the role of fire prevention and smoke separation in case of fire;

2. The window 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., which are extruded into molding materials; Ordinary plastic steel windows are not made of fireproof and heat insulation materials, so they have fast heat conduction and no fire prevention effect.

2、 Different glass materials

1. The glass of the fireproof window must be fireproof glass, with strong impact resistance and good high-temperature heat insulation performance, so as to play the role of fire prevention. The fireproof glass is filled with fireproof liquid, which will not affect the products that pass the fire resistance test of the fireproof window. The fireproof glass of fireproof window mainly includes multi-layer composite fireproof glass, grouting composite fireproof glass and Class C fireproof glass;

2. There are many types of ordinary plastic steel window glass, and there are no strict requirements for glass. It is not necessarily tempered glass, and its impact resistance is weak. However, some better plastic steel windows may use tempered glass, but the impact resistance and fire resistance are also far less than fire windows.

3、 Different fire resistance time

1. Fireproof windows can be divided into Grade A, Grade B and Grade C. Different fire ratings have different fire resistance times of fireproof windows. According to relevant regulations, the fire resistance time of Class A fireproof window shall not be less than 1.5 hours, that of Class B fireproof window shall not be less than 1 hour, and that of Class C fireproof window shall not be less than 0.5 hours.

2. The thermal conductivity of ordinary plastic steel profile itself is far more than that of steel profile, which can not play the role of fire prevention. Therefore, there is no specification related to fire resistance time.

4、 Different functions

1. Fireproof windows are composed of steel window frames, steel sashes, fireproof glass, etc., which can isolate and prevent the spread of fire. The fireproof window has an automatic opening and closing device more than the plastic steel window, which enables it to have active defense function in addition to passive fire resistance. It can be said that fireproof windows are fire-fighting facilities with fireproof function.

2. Plastic steel windows are usually used for building ventilation and lighting, with wind pressure resistance, air permeability and rainwater permeability, and poor fire protection function.

5、 Window prices are different

1. Fireproof windows have various functions of ordinary plastic steel windows, but also have special fireproof functions. They are stricter than plastic steel windows in terms of production technology and material requirements, and their installation requirements are also stricter. Therefore, no matter in any way, their costs will be higher than ordinary plastic steel windows, so it is natural that their prices are higher than ordinary plastic steel windows. The specific price of fireproof window is one square meter, which depends on the material, grade, size and fireproof glass of fireproof window.

2. The price of ordinary plastic steel windows is not high in the market generally, and it may be cheaper if you buy them in batches. The price of steel fireproof windows for buildings is several hundred yuan higher than that of ordinary plastic steel windows.

It can be seen from the difference between the fireproof window and the plastic steel window introduced in the above small edition that the fireproof window has many advantages and is better in performance and use than the ordinary plastic steel window. The building often has some loopholes in fire management or personnel operation errors, weak fire safety awareness and other factors, which lead to fire accidents from time to time. Therefore, many buildings and places have changed from plastic steel windows to fireproof windows.
