Are you faced with choosing how best to insulate a wooden house? This article will discuss choosing the suitable material for insulation of a wooden house and the best way to carry out thermal insulation.

Materials for insulation of a wooden houses

The advantages of building from wood are environmental friendliness and vapor permeability. The wood retains heat well and allows air to pass through well, creating a pleasant microclimate in the room. Therefore, insulation must be selected to preserve these essential properties of your home. At the same time, remember that wood burns quickly, so it is better to mitigate this disadvantage with the help of fire-resistant thermal insulation.

Thus, for a wooden house, the following are suitable:

 

1) Mineral wool ( stone wool, glass wool).

• Fire-resistant: mineral wool is resistant to high temperatures and belongs to non-combustible materials.
• It insulates the house well from extraneous sounds of the external environment (thanks to the large number of randomly located fibers).
• Resistant to mechanical and chemical influences.
• It retains its shape well: it does not shrink.
• It has low thermal conductivity: it perfectly retains heat in the house.
• Mineral wool is used outside and inside a wooden house.
• Sold in slabs and rolls.

 

2) Expanded polystyrene.

• Lightweight: easy to carry out installation work.
• A thin layer of polystyrene foam is superior in thermal insulation properties to other, thicker insulation materials.
• Durability: The service life lasts about 50 years.
• Resistant to the development of fungi, mold, and other harmful microorganisms.
• Refers to slightly flammable materials.
• It does not absorb moisture, so it does not need to install hydro- and vapor barriers.

 

3) Foam plastic.

It has almost the same characteristics as expanded polystyrene. However, the structure of the foam is less durable; this is due to the lower adhesion force of the granules. Therefore, its service life is at most 25-30 years.

What is the best insulation for a wooden house is up to you to decide. But remember that polystyrene foam and people almost do not allow steam to pass through so that they can create a “greenhouse” effect indoors. Therefore, it is still better to use mineral wool to insulate the wooden walls of a house. Insulation of a wooden house with mineral wool will help preserve heat and a pleasant indoor microclimate. And polystyrene foam/expanded polystyrene can be used for floor insulation.

Insulation of a wooden house from the inside

This method of thermal insulation of walls is used quite rarely. This is due to the presence of severe disadvantages and limitations of this approach:

• Reducing the size of the room due to insulation.
• An increase in humidity between the wooden wall and the insulation layer. This, in turn, leads to dampness, microclimate disturbance, and the appearance of mold.
• For these reasons, insulating houses made of beams and logs from the inside is not recommended. You can use framed wooden houses.

Work plan for insulating wooden walls from the inside:

• Apply wood impregnation with an antiseptic effect to the walls. This will prevent rotting in the future and reduce the influence of moisture on the walls.
• If you are insulating a house made of timber, fill all the cracks with jute insulation or tow.
• Create a ventilation space between the wall and the future layer of insulation. This is done by attaching slats to which a special vapor barrier membrane is attached.

Install the timber frame.

Now, you can install the insulation into the existing frame. Make sure that the thermal insulation materials lie tightly, without gaps. If there are still cracks, they must be sealed with the remains of thermal insulation.Attach another layer of vapor barrier membrane on top. Please attach it to the posts using a staple gun. The joints must additionally be sealed with tape.Next, you need to attach the slats on top of the membrane. This is necessary to create space between it and the sheathing.After all this, you need to sheathe the frame on top; usually, wooden materials are used for this: clapboard or block house.

Many companies provide insulation services in Sydney, but Ali Rapid Insulation offers years of experience, competitive pricing, and a commitment to customer satisfaction.

Advice: to improve the quality of sound insulation, it is recommended to attach insulation not only to load-bearing walls but also to partitions.

 

How to insulate a wooden house from the outside

This method has some advantages over the previous one:

• Insulating wooden walls from the outside allows you to protect the inside of the house and the wood itself from low temperatures.
• External insulation of a wooden house leads to moisture accumulating outside the building, under the ventilated facade. Therefore, excess moisture dries quickly and does not harm the wood.
• Mineral wool is often also used as external insulation.

Instructions on how to insulate a wooden house from the outside with your own hands:

• Treat the walls with an antiseptic to prevent mold and mildew from appearing on them. Apply antiseptic especially carefully to the corners of the house and the ends of the logs. Wait until completely dry.
• Make a sheathing and attach a vapor barrier layer to it.
• Place the insulation of your choice on top and secure it.
• Then, you need to attach waterproofing on top.
• After this, create a ventilated facade from beams.
• The last stage is tiling the house.

Insulation for wooden houses is only sometimes used because wood retains heat well. But if you are going to live in a house in winter, in climatic conditions, when the temperature drops to -15 or -20 degrees, then insulation will help you save on heating costs.
