Insulation of wooden houses – an overview of available solutions

Wooden houses require completely different insulation than brick houses. Due to its properties, wood can heat up quickly, but also lose heat quickly. Therefore, it is important to properly protect them and use its properties in the best possible way. Thanks to the insulation, we will be able not only to not lose heat in winter, but also to keep the house pleasantly cool during the annoying heat. Here are some tips.


Why is the insulation of a wooden house so important?


Construction of wooden houses

The latest designs of wooden houses try to take into account the ecological and economic needs of the inhabitants. The prices of electricity, gas and heating oils are getting higher and higher, so the maximum use of technology to save them seems to be a natural need of everyone who plans to build a house. Any investment of this type will pay off more when it turns out that only a small amount of energy is enough to raise the temperature in the house during frost. Over the entire life cycle of a building, the cost of construction is just 11%, while 80% is spent on heating and hot water.

It is also worth mentioning that good insulation is not only protection against inadequate temperature, but also against noise. The insulation placed between the wooden beams reduces the noise typical for wooden houses and thus increases the comfort of living.


Ways to insulate a wooden house


Today, there are many different ways to insulate wooden buildings. We can choose the type of insulation according to our own needs and the house we want to live in. For example, we can choose a wooden house, energy-efficient or maybe a house that is as economical and ecological as possible, i.e. a passive house. It is a decision that we have to make at the level of estimating construction costs. It is obvious that the best insulation or solutions used in passive houses are much more expensive than more traditional methods. Estimating our finances will be the starting point for specific technological options. However, we should not save on insulation. It is better to finally opt for a slightly smaller house, but better insulated. Wooden houses, especially frame houses, are much easier to expand than brick houses,Wooden houses require precision in execution. Any mistake in construction can result in problems later, which the insulation will not stop. Therefore, you should choose a company that has experience in building this type of house.

Each insulation material we choose affects not only the temperature in the building, but also acoustics and fire safety. We should pay attention to all these factors. Most often, the internal walls of wooden houses are insulated by installing a windproof foil on their entire surface. It is covered with mineral wool boards, which are additionally secured with a vapor barrier foil (it protects against moisture penetration), and the last layer is made of plasterboard. If this type of insulation is not sufficient for us, we can use a similar method to protect external walls. The key element of insulation when using mineral wool is the vapor barrier foil, because if moisture enters the mineral wool layer, it loses its insulating properties.

Roof insulation

Roof insulation in a wooden house can be achieved in several ways. The most popular materials used for insulation are: mineral wool, extruded polystyrene, polystyrene, thermal insulation foil, wood-magnesite boards and PIR polyurethane.The most popular material is still mineral wool, which is used for all kinds of insulation. It is worth noting that PIR polyurethane is characterized by very good insulation, which makes it possible to use thinner boards that are suitable for under-rafter, over-rafter and inter-rafter insulation. Extruded polystyrene works similarly, but it is much thicker, so placing it under the rafters reduces the room by a few centimeters. On the other hand, the thermal insulation foil is the most modern insulating material. It is thin (even 1-2 cm) and the best of all mentioned. Unfortunately, it is also quite expensive.


Insulation of wooden houses and construction law regulations


The building law includes points related to the insulation of buildings and they are just as important as energy security or proper stabilization of the building structure. Insulating a home is legally required, although ultimately no specific determinants of how buildings should be insulated do not emerge. There are, however, determinants of what should be the minimum thermal insulation of building partitions. These types of requirements may change, so it is worth getting acquainted with the construction law before we start designing our new home.
