It is worth noting at the beginning that the construction work in the winter is not recommended, but it does not mean that it is completely impossible. In winter it is possible to perform most of the work at home, it is only important that the temperature inside was positive, although in the case of some building materials adapted to the low temperatures, this is not a problem. In the case of external works, the temperature -5 ° C is considered to be the temperature below which any construction work should not be executed, regardless of the type of building materials. If the temperature is between +5°C and -5°C, then special mortar designed for low temperatures should be used for masonry works and cellular concrete blocks adequately protected against frost. Whether to start the work in this case, the site manager with building control inspector decide. Putting aside the question of the permissible minimum temperature, there are other contraindications for works at a construction site in winter months, mainly related to the quality of its performance and safety of workers. Now, works at low temperatures require the use of protective clothing, including gloves. Precise stacking of blocks or mounting the door frames can be difficult just because of the thick gloves. Besides, even a well-protected area of masonry work can be frozen, which certainly will not have a positive impact on the durability of executed works. Also, we should not forget the possible icing of entry paths or stairs, very dangerous both for people working at height, as well as on a stable ground.
