How to insulate wooden walls and when is it necessary?
If in a log house in the winter it's cold and damp, you can unequivocally state that when it was erected, the builders saved money on insulating materials. From this article you will learn how to insulate wooden walls, so that for many years they served as a reliable protection against winter cold and summer heat.
In order to make your home more comfortable, you must first understand why it is so hard to warm up. What could be the reasons? Here are some of them:
- lack of a seal between the crowns;
- the thickness of the beams or logs does not match the climatic conditions( in the central strip of Russia houses are built of sawn timber not less than 30 cm thick);
- weak insulation of the floor, in particular this refers to houses that have a basement in the underground;
- poor-quality logs docking at the corner joints, because of this, drafts can run around the house, and the corners in winter will freeze;
- in the construction of an error in the calculation of the ratio between the area of walls and windows;
- violated the rules for erecting a foundation or a roof.
If at least one of the listed reasons is present in your home, you can proceed to the preparatory work.
Than to insulate the walls of a wooden house - choose the materials
The simplest way of warming is laying of an additional layer of an interventicular seal. That is, it is necessary to lay an additional insulation for the walls of the wooden house between the logs, in other words, to protect it. It is advisable to do this not only outside, but also inside the building.
External insulation of a wooden house will enable to increase the insulating qualities of log walls. And besides, this in no way will not affect the area of rooms. What to insulate the walls of a wooden house, what methods and technologies are most suitable for this?
Here are just some materials for the insulation of houses, which offers a modern construction market:
- linen felt;
- jute - a universal material that is sufficiently resistant to rotting processes, is produced from fibers of jute plants;
- flax fiber or towel - heater, is made of flax stems in the form of ribbons up to 15 cm wide, is designed for sealing gaps and various gaps in wooden houses.
- basalt wool;
- polyurethane foam.
The use of modern thermal insulation materials makes it possible to conduct a warming of a wooden house without significantly increasing the loads on its foundation. This effect can be achieved by applying a heater for walls of wooden buildings based on mineral wool.
Thermal insulation outside the walls of the wooden house - we proceed to work
Work on the facade cladding at home with energy-saving materials begins with the treatment of walls with special antiseptics. Further, all cracks are sealed, defects and damages are eliminated. After that, rolls of mineral wool are rolled on the wall, and fixed on it with special anchor bolts.
Before installing the plating, the insulating layer is covered with a protective material and covered with boards. To protect the skin from the effects of moisture and sun, it can be covered with several layers of varnish or oil paint. In order to ensure good air circulation and prevent the formation of moisture in the insulation, it is recommended to equip ventilation ducts near the foundation and the eaves.
For the same purpose, a gap of a few centimeters is made between the insulation layer and the facing material. This technology is usually used if the insulation of a log house under siding is carried out, when the presence of an air gap is mandatory.
