A serious problem was discovered by the owners of the Yaojiang product. Wall insulation materials Flame retardancy may not be up to standard.
The worried owner tried to prove his concern at the scene of Renovation: a landlord lit the foam of the wall insulation with a lighter, and the fire soon burned up, and the flames continued to perish and smoke thick black smoke.
 The owner lit a fire on the wall insulation material. What's the matter?
An owner looked at the burning fire and said anxiously, "you see, this is not frightening. Once the wall is filled with flames, the insulation material will burn up immediately."
The owner will find the problem to complain to the relevant departments, the relevant departments entrusted the quality supervision and Inspection Institute to test the wall insulation board used, the test result is B1 level, conforms to the design requirements, but the owner does not recognize it. The construction unit indicates that after the May Day holiday, the qualified inspection unit will be commissioned to detect the insulation board once again after the May Day holiday.
According to the owners, the urban and Rural Construction Bureau and the fire department have asked the developers to check again, but the developers have not yet submitted the inspection, but they have strengthened the security on the construction site.
The owners have checked the national standards online. According to the GB8624-97 regulations, the combustion properties of building materials can be classified into four grades:
(1) class A: non combustible building materials, hardly burning materials.
(2) B1 grade: flammable building materials, which have good flame retardancy, can be exposed to open flames in the air or difficult to catch fire under high temperature. It is not easy to spread quickly, and when the fire source is removed, the combustion will stop immediately.
(3) B2 class: flammable building materials, which have certain flame retardancy, will be igned and burned in the air when exposed to open fire or under high temperature, which will easily lead to the spread of fire, such as wooden columns, wooden houses, wooden beams, wooden staircases, etc.
(4) B3 class: flammable building materials, without any flame retardant effect, highly inflammable and highly dangerous.
The code for fire protection design of tall buildings also has mandatory requirements for building insulation and exterior wall decoration materials. The interior and exterior insulation systems of buildings should adopt thermal insulation materials of Grade A, and B2 class insulation materials should not be adopted, and B3 class insulation materials are strictly prohibited.
According to the owner's on-site verification, the materials used by developers and B1 grade materials are not easy to fire when they are exposed to open fire, and the description of combustion immediately ceased when the fire source moves away is not consistent.
Some owners asked developers to dismantle the insulation, but developers asked the owners to sign an agreement and agreed to postpone the delivery (the contract was written in late October at the end of 19).
More importantly, if the owner wants to remove the insulation, the developer will charge another area.
In order to buy this room, the owner has spent 3000 yuan / flat decoration fees, now because of the insulation problem again to charge, the owners really can not accept.
In the city message board, the owner also complained about the quality price discrepancy of the decoration: the developer paid 3000 yuan / flat decoration fee for the owner, and the decoration cost per household was as high as about 300000 yuan, but there was not a large electrical appliance. According to the cost of building decoration materials, the cost of decoration is about 800 yuan per square meter. For this doubt, developers responsible person to the owner said: "the contract is written in the valuation of 3000 yuan, not to take 3000 yuan to decorate."
For this complaint, the relevant departments have also made a positive response: "when the developers sell the whole decoration commercial housing, they should set up the standard sample room at the sales site according to the regulations, and publicize the information about the brand and type of the main materials and equipment for decoration, as well as the sample of the house decoration contract. Looking at the decoration contract signed after the model room, it is actually the contractual relationship between the equal civil subjects. Buyers who believe that the quality price is not consistent should be resolved through consultation with developers or third party agencies and judicial proceedings.
Last year, an owner of Wuhan once worried to me: "what I am most worried about is not formaldehyde and other unfriendly things, but the wires buried under the floor and walls. If the quality is not up to standard, it will be very easy to cause fires. If we live in high-rise buildings, it is really dangerous. Because after the delivery of the house, you can't guarantee that all the owners upstairs and downstairs will be demolished and redecorated, so this is the biggest hidden danger.
"Fengyun Wuhan" also expressed deep concern about this: this involves the whole building owners life safety problems, we must not take it lightly!

Finally, Xiaobian once again stressed that building fires can not be underestimated. Many buildings are all flammable materials as media after fire, and wall insulation materials run through the entire building. Nanyang Yitong YT insulation materials, class a non combustible, overcome the traditional insulation materials easy to crack, cracking defects, and can achieve no net construction, cost-effective, in the national market implementation for more than 20 years, has been the national institutions and users alike, you can understand. In addition, fake and shoddy products are rampant in the market. In order to ensure the use effect and buy YT thermal insulation materials, please recognize Nanyang Yin Tong.
