With the continuous development of technology, the functions of decoration building materials are more and more. Insulation fire doors are a building material that has only become popular in recent years. Today we will introduce the wood insulation fire doors together to understand!
What is wooden heat insulation fire door
The wooden heat insulation fire door refers to the wooden door that uses wood or wood products as the door frame, door leaf frame, door panel, the door leaf is filled with heat insulation material or the wood or wood product is used as the door frame, door leaf. Above the composite fire-resistant glass and door leaf, there is a bright window composed of a door frame and Class A composite fire-resistant glass, and it is equipped with a fire-resistant hardware accessory to meet the fire resistance integrity and thermal insulation door.
Classification of wooden heat insulation fire door
According to the fire resistance limit, wooden heat insulation fire doors are classified into Class A, Class B, and Class C. The fire resistance requirements are 90min, 60min, and 30min. The wood used for making solid wood fire doors needs to be dried and flame retardant. The moisture content should not be greater than 12%. When restricted by conditions, the moisture content of its production should not be greater than the local equilibrium moisture content. The hardware fittings used for wooden heat insulation fire doors must be fire-resistant hardware fittings. The main hardware fittings are: fireproof hinges (hinge), fireproof latches, fireproof door locks, fireproof sequencers and fireproof door closers.
The fire resistance of wooden heat insulation fire door During the fire resistance performance test, the wood heat insulation fire door should be able to meet the conditions specified in the standard within the time required by its fire resistance performance.
Purchase of wooden heat insulation fire door
1. Integrity: There is no continuous flame burning for more than 10s on the backfire surface; if cracks, holes or other pores appear on the backfire surface without flames, combustible materials with a distance of 20mm ~ 30mm from these pores cannot be used. Ignite within 10s ～ 30s; the sample must not collapse.
2. Heat insulation: When the average temperature rise of the temperature measurement point on the solid wood fire door reaches 140 ° C or the temperature rise of any temperature measurement point reaches 180 ° C, the heat insulation is judged to be lost. When conducting a product consistency check on site, the following should be checked:
1. Whether the appearance of the product is consistent with the standard requirements;
2. Whether the product logo is consistent with the standard requirements;
3. Whether the product structure is consistent with the test report;
4. Whether the material of the product is consistent with the test report;
5. Whether the performance parameters of the product are consistent with the test report.
