At construction forums, questions are often asked whether it is necessary to handle the roof rafters. And if necessary, what means? To answer these questions, it is worth thinking about the dangers waiting for the wooden structures of the roof throughout the entire period of its operation.

What do you need to protect the roof rafters?
Even if the roof design is equipped with an ideal system of underpressure ventilation, the roof always remains an element of the house exposed to moisture. Outside - these are atmospheric precipitates, and from the inside - air pairs, rising from the warm rooms of the room and condensing in the upper part of the house, in particular on the supporting structures of the roof - wooden rafters. The constant exposure to moisture is primarily open wooden structures - the lower crowns from the log and timber, the framework elements. This is especially true for areas with a wet climate.

The wet environment contributes to the reproduction of microorganisms and insects. Therefore, mold, fungi, contributing to rotting wood on wooden surfaces. In addition to these microorganisms, the roof rafters can be chosen as a favorable habitat of insects. Therefore, first of all, the wooden structures of the roof requires biosis - processing safe for people and animals, but preventing the reproduction of insects and microorganisms with a chemical agent.

And of course, the second enemy that lies rafters the roof, it is fire. The tree is a flammable material. And it is impossible to forget about it, especially in areas with a dry roast climate. Therefore, for complete confidence in fireproof, the rafter is also recommended to process them with flame retardants.
What means to choose for processing rafters?
The modern market offers many effective tools for bio and flame retardants of wooden structures. However, if we use them separately, the processing of wood has to be carried out in several stages. Initially, an antiseptic is applied to several layers, and only later - with antipirens. As a result, the process becomes rather long and time consuming. Therefore, the most modern scientific development in the protection of wooden surfaces is universal means that contain in its composition as surface-active substances that prevent the reproduction of microorganisms and insects and solutions of salts, which, when contacting with fire, form a resistant flame retardant film. As a consequence, wood changes its properties and becomes a reflare material.One of the most modern universal means is the firebobes of wood TechnoNIKOL (10 and 20 L). As part of the impregnation - a complex of highly efficient biocides and antipients. The tool is safe for people and animals, no arsenic and chromium compounds.
It is ideal for protecting wooden structures used both inside and outside the room. However, the external elements at the same time should not come into contact with the soil and exposed to atmospheric precipitation.
Advantages of firebounds of wood TechnoNIKOL
- The means is applied once at least 500 g / m². It is with this consumption of impregnation that the tree becomes a difficult-scale material, acquires the properties of substances that relate to the group of flame retardants.
- The impregnation provides fire protection for more than 7 years, and biosecurity - for 20 years, which eliminates the flow of rotting under the flame retardant film.
- The structure and properties of wood in the processing process do not change, the impregnation is not susceptible to aging, leaching and planting.
- The tool can be applied both for the first time and on the previously processed surfaces. After that, wooden surfaces can be glued, covered by any paint and varnish materials.
Application rules
- Wood surfaces need to be cleaned from chips, sawdust, dust and old paint. If the tree has already been infected with mold that influenced the color change, before applying the impregnation, it is necessary to use bleach for wood.
- If the tool is applied on the finished roof design, the roller is used, the brush, sprinkler. At the same time it is applied abundantly and evenly.
- If the rafters are not yet installed, it is better to immerse them into a solution for 30-60 minutes. This method is convenient for simultaneous processing of a large number of wood parts.
- Processing must be carried out at a temperature not lower than + 5 ° C. At the same time, it is necessary to exclude the falling on the processed surfaces of water and atmospheric precipitation.
- When using impregnation, glass surfaces need to protect. Be sure to use personal protective equipment: glasses, mask, gloves. If the solution is hit on the skin or eye, you need to wash these sections with plenty of water.

Take care that the rafters of your roof serve you for many years. Application of a universal means of fire-beeps on wooden structures will help you to significantly save on the repair of the roof in the process of its long-term operation.
