Fire protection of timber is represented by the combination of methods and techniques that allow maintaining bearing and other design properties of building structural units when exposed to fire during certain period of time. The variety of factors, such as an access of oxygen, air draft, and projected fire intensity should be taken into account while choosing efficient methods and techniques of fire protection. Along with that, when applying various methods of fire protection, it’s crucial to preserve natural properties of timber determining comfortable indoor climate. Within this context, “soft” timber modification is preferable. Thus, finding methods lowering combustibility of timber, while preserving its unique natural properties, represents the goal of this study. The present paper studies fire-proof efficiency of compounds based on mono-and di-ethanolamine-(N→B)-phenyl borates by means of ‘ceramic pipe’ method. Durability of shielding effect of the designed compositions was assessed by the method of determining ageing resistance. It was established that “soft” surface modification by the compositions based on mono-and di-ethanolamine-(N→B)-phenyl borates allows upgrading timber to the class of flash-resistant materials and enables to increase fire resistance significantly (period of fire resistance accounts for 90 min), along with that, protective effect remains after accelerated ageing of timber.
