At present, there are two standards for the detection of fire-resistant Windows: GB/T 12513-2006 "fire-resistant test method for glass-inlaid components" and GB16809-2008 "fire-resistant Windows". Differences between the two:

A. According to GB/T 12513-2006 can only test the fire resistance, according to GB16809-2008 can only test the fire resistance, can also test all items according to the fire window.

B. According to GB/T 12513-2006 only need to send one sample, according to GB16809-2008 only need to send one sample to test the fire performance, according to the fire window test all items need to send two samples (according to the provisions of standard 9.2, two samples are used for testing different items).

C. Movable fire-resistant window, according to GB/T 12513-2006 does not need to test the automatic closing performance, according to GB16809-2008 need to test the automatic closing performance, requirements: before the test, the window sash is in the open state, the fire test after 60 s (including 60 s) automatically closed reliably, otherwise unqualified.

At present fireproof window is common have: steel qualitative fireproof window, broken bridge aluminum fireproof window, aluminum alloy fireproof window and model steel fireproof window. Steel refractory Windows generally refer to the practice of non-heat insulation fire Windows, broken bridge aluminum and other materials of refractory Windows will generally be set in the window frame or skeleton steel lining or aluminum lining to increase the strength, and some also fill castables to enhance the fire performance. GB/T 31433-2015 "building curtain wall, door general technical conditions" article 5.1.5 regulation: "there is a requirement for refractory integrity of outside doors and Windows, glass used in a layer of rare compound GB 15763.1 the provisions of the outer plastic doors and Windows, outside doors and Windows, gangsu composite steel-plastic co-extrusion outside doors and Windows, aluminum-plastic co-extrusion outside Windows and doors profiles used to strengthen steel or aluminum line should be connected into the framework of closed, and inside the glass Mosaic notches to take measures to prevent the glass fall off after a fire".

Installation Precautions

Attention points for fireproof window installation:

(1). Fire-resistant window installation according to the size of the design reserved hole, should not be the fire window frame directly embedded in the wall, otherwise it will affect the overall window wall fit, then the future use will be affected.

(2) for the light wall material built into the hole, should be in advance in the connection or surrounding the hole for the corresponding treatment, to ensure the reliability of the connection, can not be directly connected with the light block fixed.

(3) installation of plastic doors and Windows hardware accessories, the screw should be fixed in the lining reinforced steel or lining local reinforced steel plate, or make the screw through the plastic profile at least two layers of wall thickness, to ensure its stability is not easy to deformation and other situations.

(4). Push-pull fire-resistant window sash installation can adjust the limit card and other anti-falling measures, the limit card is suitable for installation on the top of the side of the window sash. Box fan after push-pull fireproof window is installed should have no visible deformation, switch is very flexible, door fan closes tight.

Our general fire window can be divided into two categories, broken bridge aluminum fire window, one is we often can see the steel fire window, steel fire window can be divided into fixed steel fire window and can open the steel fire window, the use of 2.0-1.8 for the steel frame and then spray fire expansion sealing strip with a single middle. In addition, fireproof glass can also be used composite fireproof glass, broken bridge aluminum refractory window price, generally this kind of and the home window is almost another kind of fireproof window is wood fireproof window, is not the same as the frame but there is no conventional can open more fixed glass.

The material of the traditional fire window is usually steel, wood, steel and wood composite, and the glass is type A heat insulation type fireproof glass or type C non-heat insulation type fireproof glass. Although the steel fireproof window is strong and has good fire resistance and heat insulation, it has poor heat preservation performance and sealing performance, and is not resistant to corrosion and climate aging. The external window closure device and temperature sensing support device of the broken bridge aluminum fireproof window lack of light aesthetic feeling, and can not meet the use requirements and aesthetic requirements of building external Windows.

Fireproof window fireproof equipment may be we are more familiar with the fire door, their working principle is basically the same. Both use the way of partition to control the spread of the fire, the fire control within the burning range, in order to avoid causing uncontrollable fire burning, different from our ordinary family used in the window. The reason why this window has the fireproof performance is because it has a good temperature sensing ability, when it feels the temperature rises to the temperature will automatically close, so that even if there is no one control no one monitoring the case of fire can also use such fireproof window fire mitigation

The window frame and window are adopted by the fire performance of materials, and it also has a general sense of the Windows of all functions, can be said to be both device, install the fire equipment is needless to say, the benefits of natural and man-made, we often said that is a lot of disaster is we have no way to control, install the disaster prevention equipment can effectively help us to reduce the happening of calamity, does not the devastating disaster.

Note: the opening and closing control mode of the window sander can be supplemented with electric control mode, such as electric signal to control the closing or opening of the electromagnet, electric signal to control the closing or opening of the motor, electric signal to control the closing or opening of the pneumatic mechanism, etc. The automatic closing time of the sash of the movable fire window should not exceed 60S.

The external Windows with fire integrity requirements shall be tested in accordance with the requirements of the current national standard "Fire Resistance Test Method for Glass Inlaid Components" GB/T 12513.

The broken bridge aluminum fire-resistant window is to increase the fire prevention function on the basis of ordinary aluminum alloy window. It is the same from the outside, but it is completely different from the inside (it can be seen intuitively through the section diagram). Ordinary aluminium alloy window due to the limitation of aluminum, its melting point is 600 degrees Celsius, aluminum alloy melt in melting point temperature is reached, lead to the window frame to soften the collapse of losing so much integrity, under standard fire temperature curve, 10 minutes after the fire broke out indoor temperature has more than 600 degrees Celsius, to reach the melting point of aluminum alloy, but in order for aluminium alloy window have fire prevention function, some manufacturers will be inside the hollow aluminum alloy layer fill some incombustible materials have certain block heat conduction (material), Or in the broken bridge aluminum refractory window structure to add some steel fixing parts to maintain the aluminum alloy after melting can still maintain the stability of the framework to 0.5 hours, 1 hour will not collapse and fire.

Because aluminum alloy is metal, heat conduction is faster, so when indoor and outdoor temperature difference is very much, aluminum alloy can become a "bridge" that transmits heat, such material make it doors and Windows, its heat insulation performance is not good. The broken bridge aluminum is the aluminum alloy from the discontinuous open, it uses hard plastic will be broken aluminum alloy is connected as a whole, we know that plastic thermal conductivity is obviously worse than the metal, so the heat is not easy to pass through the whole material, the insulation performance of the material is better, this is the "broken bridge aluminum" name.

      There are six points to distinguish between the two.
      1, application parts: fire window non-building external window, used for indoor partition more, fireproof window is more used for building external window.
      2, performance requirements: because the fire window is used in the room, so there is no hard water tightness requirements, only the air tightness, wind pressure resistance performance can meet the standard. The fire resistance needs to meet the integrity and heat insulation at the same time, and the fire resistance limit is between 0.5h and 3.0h. Notable is, the heat insulation here and the door window heat insulation performance that we ferial say is different, this heat insulation points to isolating heat radiation, reduce baking feeling namely, the heat insulation is isolating heat conduction.
      Fire-resistant window not only requires air tightness and anti wind pressure performance, but also requires water tightness, heat preservation performance and so on. Fire resistance only requires integrity, not heat insulation. The fire resistance limit is 0.5h, 1.0h.
      3, function configuration: fireproof window than fireproof window has an automatic opening and closing device, so that it can resist fire passively in addition to more active defense function.
      4, frame material and structure design: the section of the fireproof window is mostly symmetrical structure, and the fireproof external window is mostly asymmetric structure.
      5, panel material: heat insulation type fireproof window should use heat insulation fireproof glass, non-heat insulation type fireproof window can use non-heat insulation fireproof glass. Fire-resistant window can use non-heat insulation fireproof glass. Are you getting dizzy again? Yes, fireproof Windows are also called fireproof glass.
      6, fire conditions: fire Windows to prevent indoor fire, also known as restricted space fire, fire resistant window to prevent outdoor fire, that is, open space fire.

4 points of attention for fireproof window installation:

(1). Fire-resistant window installation according to the size of the design reserved hole, should not be the fire window frame directly embedded in the wall, otherwise it will affect the overall window wall fit, then the future use will be affected.

(2) for the light wall material built into the hole, should be in advance in the connection or surrounding the hole for the corresponding treatment, to ensure the reliability of the connection, can not be directly connected with the light block fixed.

(3) installation of plastic doors and Windows hardware accessories, the screw should be fixed in the lining reinforced steel or lining local reinforced steel plate, or make the screw through the plastic profile at least two layers of wall thickness, to ensure its stability is not easy to deformation and other situations.
      (4). Push-pull fire-resistant window sash installation can adjust the limit card and other anti-falling measures, the limit card is suitable for installation on the top of the side of the window sash. Push - pull type fireproof window after installation frame fan should be out of shape without inspection, switch is very flexible, door leaf is closed also close.

According to the different frame material, there are mainly steel, wood and other metal fire Windows, the vast majority of the current market using steel fire Windows; Its performance is stable and heat resistance is good. According to the use of different parts of the common grade for class B; Fireproof window fireproof time of 1.5 hours; Class B fireproof Windows are fire-resistant for 1 hour.
      According to the function, there are two types of fixed fire Windows and movable fire Windows. The opening mode is flat or winding movable Windows can be equipped with self-closing system in case of fire. In case of self-closing in case of fire, the whole building fire control system can also be connected, under the unified command of the control center.

Fire window is divided into heat insulation type and non-heat insulation type, the former is generally used, the glass with more than 25mm heat insulation grouting fireproof glass, its performance can be comparable with the fire prevention six, the frame glass joint using steel laminating fixed. To ensure its firmness, the gap is inset with a fire expansion strip to expand immediately after reaching the temperature, to prevent smoke channelling.
