Tell me the option of floor insulation in an old house built in the early 20th century?
Hello, my question is very simple: how to insulate a wooden floor in a private house efficiently and inexpensively. Of course, there are a lot of tips on this subject now, you also have it on the site - I’ve read everything. In my house (inheritance) there are only 3 rooms and a concrete floor, and when you enter, then 2 steps down. This is an old house of the beginning of the 20th century and before it had an earthen floor, but then part of the soil was removed and poured concrete, which was simply periodically painted with paint. But in this form, the dampness in the rooms, and the screed in many places just crumbled, I will clean it. Tell me the most budgetary option for warming such a floor, specifically choose a model? Most importantly, there are a large number of high-quality lumber available.
The best option for floor cake
We understand that the fact of the presence of wood should be the key when considering the design of the floor cake in your case. So, we will consider the device of a wooden floor, but we advise you the so-called "double system". The essence of her device is as follows:
- Wooden boards are laid on a prepared base.
- A pillow of pure river sand is poured onto such a flooring.
- A layer of thick cardboard is laid on top.
- From the subfloor arranged in the manner described above, 4 cm recedes and the lag is installed.
- Between the lags a heater is laid.
- The final coating is laid.
Draw your attention to! In order to prevent various deformations during the arrangement of the wooden floor due to temperature differences along the perimeter, it is necessary to leave small distances, literally 1 cm, near the walls. Such expansion joints should be performed with the subfloor and the finish coating.
We select a heater
Since this is an old house with a wooden floor, mineral wool is quite suitable as a heater. It will provide excellent ventilation and protect against mold and mildew.
As an option, however, more expensive, foam can be used as a heater. It has exceptional thermal insulation and sound absorption. In addition, this material is non-combustible and inert to chemicals.
