Fireproof treatment of wooden structures of attics: features

The attic is one of the most fire hazardous places in any building. After all, it is here that complex wiring nodes from around the house are most often concentrated. The occurrence of the slightest circuit is an extreme danger to the facility. That is why timely fire-retardant treatment of wooden structures of attics is so important . Let's see what are the features of the implementation of such events.

What is the purpose of applying a fire retardant coating on wooden structures?

Thanks to fire protection of attic floors, the following tasks are solved:

• accidental fires are prevented;
• potentially dangerous factors are weakened, the action of which can lead to a fire;
• slows down the development of fire in the initial stages;
• localized open flame.

Primary requirements

Is fire retardant treatment of wooden structures of attic buildings required? This is what state building codes say about it.

According to the provisions of SNiP, fire-retardant treatment of wooden structures of attic rooms should be carried out in places between the roof and ceilings. Rafters and crates are required to be applied to fire fighting compounds .

Even from a few short excerpts, it can be judged that the fire-retardant treatment of attic spaces is a mandatory precautionary measure when putting an object into operation.

Additional requirements

Among the optional measures for protecting attic rooms from fires, it is worth noting:

1. Installation of fire hatches - act as a means of emergency access to the attic and make it possible to keep the spread of open fire up to 30 minutes.
2. The creation of special distributions is an effective solution that allows you to stop the rapid ignition of ceilings by dividing the attic area into separate sections covered with non-combustible materials.
3. Compliance with the rules of operation of the premises - it is forbidden to accumulate garbage, litter the space nearby the supporting structures.

Fire Protection Classification

Specialized tools that are used during fire fighting are primarily divided into solid and liquid categories. The first, in turn, are divided into superficial and deeply penetrating. The solid compositions with which fireproofing of wooden structures of attic spaces is possible include all kinds of dusting and coating.

According to the nature of the action, all flame retardants are divided into passive (prevent the effect of high temperatures on the deeper layers of materials) and active (directly affect the combustion process).

How is fire-retardant treatment of wooden attic structures performed?

Activities aimed at protecting roof ceilings from fire are carried out by employees of specialized services on the basis of an appropriate license. In the course of work:

1. The calculation of the room area is carried out, which reduces the risk of fire, based on existing conditions.
2. The building is audited for compliance with the priority requirements for the fire treatment of attics.
3. The necessary fire protection measures are determined.
4. Liquid compositions or solid materials are applied to the floors, taking into account the required class of fire treatment.
5. An examination of the quality of work is carried out, a corresponding act is drawn up.
6. Confirmation papers are presented to the owner of the object.

Fire protection

What are the materials for the fire treatment of attic floors? Currently, several fire protection options are used.

First of all, it is worth highlighting paints and varnishes. This includes all kinds of non-combustible mastics, paints, varnishes, impregnations. The refractoriness coefficient of such products is indicated on the container.

Fire retardant treatment of wooden attic structures may adversely affect human health. Therefore, the mandatory requirement for applying liquid paints and varnishes is the use of personal protective equipment.

For fire protection of load-bearing structures, they most often resort to the creation of special fire-resistant barriers in the form of plasterboard or plasterboard. The internal space between the materials is filled with non-combustible mineral fillers.

Alternatively, more reliable, but at the same time expensive, solutions, such as rolled materials and vermiculite-based liquid formulations, can be used to protect attic floors.

According to the fire safety rules, these measures with the use of refractory products can be performed independently directly by the owners of the facility. However, in practice, such actions are extremely negatively considered by representatives of the Ministry of Emergencies. In order to avoid troubles, work aimed at protecting the attic space is recommended at least under the supervision of a fire inspector.
