Why Wooden House?

Wood is alive. A wooden house is warm, durable and has character. Wood is a natural material and a wooden house is eco-friendly, green and has a low carbon footprint. A wooden home is comfortable. Wood is sustainable and one of the oldest building materials.

Popularity around wooden homes is continually growing around the world. Energy efficiency, healthy living environment, short construction time and affordability are important factors. Wood is also strong, durable, flexible and fire resistant if treated properly. That is why it is worth choosing a wooden house.

Eco-friendly and healthy

Wooden houses are very good for your health, wood has a unique ability to “breathe” and balancing the indoor air and temperature. Air passes through the grains of the wood, purifies, moisturizes and maintains a comfortable temperature. As a result, there is always a comfortable microclimate in the house, which is especially important for children and people with various allergies. It is widely recognized that the warm and natural color of wood positively affects the mood, soothes the nervous system and creates favorable conditions for rest. Clearly a wooden house is not just a building, but a unique world to which you can invite friends and family.

Easy and fast to build with low maintenance costs

Wood construction is fast and efficient. The manufacturing processes are done in our production facilities, and only the assembly and installation is done on site. Wood structures can be built year-round in most climates. A wooden house up to 100m2 can be delivered and ready for occupancy in as little as three months.

Wood is the most prominent natural thermal insulation material

In wooden houses a comfortable microclimate is naturally maintained. It is warm in winter and cool in summer. Logs have the function of accumulating excess moisture and then releasing it back, helping to maintain an optimal temperature in the space.

Wooden walls have a great ability to accumulate heat. They store heat and control room temperature. This determines the comfort inside the house.

Wood is the world's greatest renewable resource.

Properly harvested, wood is much more sustainable than its metal alternatives. Materials like steel and aluminum require much more energy to produce. Forests can be carefully planted, cut down, and replanted to produce a steady stream of resources without negatively impacting the environment.

If you are concerned about whether the wood used to build your home comes from a sustainable forest, make sure the wood is certified. Certification by entities like the Forest Stewardship Council (FSC) and the Programme for the Endorsement of Forest Certification (PEFC) ensures that the wood was harvested from responsibly managed forests.

We buy our house timber from Sweden and it is FSC certified as well as C24 and CE certified.

Wood is a durable building material

Timber frame houses built according to modern technologies, are highly reliable and durable. 

Wood construction can last up to several hundred years, depending on care and quality of construction. Longevity of a timber frame house in terms of function and use is determined by :

  • Quality of construction
  • Frequency of repairs and maintenance
  • Local climate

Properly built and maintained houses can stand for centuries. In Scandinavian countries and Siberia there are 600-700 year old houses.
Horyuji, an ancient Japanese temple built in 607 AD, is the oldest surviving wooden structure in the world.
No material has been able to match the unique qualities of wood, including strength, durability and ease of use, natural heat resistance and stability. Wood is also excellent at absorbing and resisting vibration. 
Solid wood structures exhibit very high fire resistance. When exposed to fire, the wood surface is charred, preventing further fire development.

Environmentally friendly

The assembly process of a prefabricated wooden house is designed to have no impact on the surrounding flora and fauna. The manufacture of wood products consumes 10 times less energy than the manufacture of other building materials.

Cost-effective

A wooden house is easy and quick to build, is energy efficient and protects our environment. Using wood as a building material provides a healthy living environment for us and future generations. This combined gives us the opportunity to save time and money while enjoying a nice and comfortable atmosphere.

How are we going to build your wooden house?

Preparing a timber construction

DEM-BUD houses are manufactured from the highest quality wood. Wooden elements are cut into appropriate shapes and sizes, what allows to minimize wood waste, reduces costs and is environmentally friendly. All houses are manufactured on the site of DEM-BUD company. This allows the company to control every element of the production process, so it can maintain and ensure the highest quality of their homes.

Foundation

Before the frame is set, it is essential to prepare the foundation. Most Scandinavian houses are built on a slab foundation, although it is also possible to build on foundation walls.
Since wood is a lightweight material, you can save a lot on foundations by building on a foundation slab. Making the foundation slab is much less labor intensive than the foundation strips, and thus much faster and cheaper. In DEM-BUDZIE we employ a qualified team of specialists who know how to make these type of slabs. Slabs work well on weak soils with unfavorable physical parameters.

The frame of a house

The frame of a house in Scandinavian construction consists of vertical wooden pillars placed 30, 40 or 60 cm apart. Identical spacing between the pillars is crucial, even if there is a window planned on the wall. A beam is installed in its place, which serves as a lintel. The spacing between the posts is planned so that the house can be easily covered with OSB panels, which strengthen and bind the whole structure. The posts are tied at the top with two eyelets. One of them binds individual posts together, and the other binds the entire walls together.

The wood used in the construction of the building is a key factor for the quality of the house. The type and treatment of the wood affect the strength, moisture content, fire resistance characteristics. It is the most important factor and that is why a weight of 0.3 is given.

 

The frame of each DEM-BUD house is made of the highest quality wood. We obtain our materials from trusted and reputable suppliers. Sawn timber is imported from Sweden from a reputable supplier, which has the FSC forestry certificate.

Walls of the house and the roof

Walls support the roof, which is made of wooden beams with parameters and spacing selected for the specific project. OSB boards are mounted on the beams, and if the client cares about boarding, then the boards are nailed. It is very important for the future acoustics in the house to take proper care of the ceiling insulation. In houses with a usable attic a double insulation is made: between the beams and under the floor.
The use of foil is extremely important for a good indoor climate and for proper insulation and energy parameters. The wind-barrier foil is used on the outside and the vapor-barrier foil on the inside. Regular cardboard-plaster, cardboard-fiberboard or paneling is laid on top of a structure prepared this way from the inside.

After making the wall structure, the spaces between the pillars are filled with insulation. Most often mineral wool is used for this purpose, although other types of insulation, such as spray-heating may be used.
Because of the way the ceiling is fixed in DEM-BUD houses, this type of construction belongs to the so-called platform construction – planks are placed on the top of standing walls and which make the frames of the ceiling, and on them the floor is laid with wooden planks or boards. Higher walls are constructed using the floor as a working platform.

Flooring

The type of foundation determines the laying of the floor. In the case of a slab foundation, it will be a floor laid directly on the ground, while in the case of foundation walls, it will be a floor laid over a ventilated space.

Wooden construction of the floor and roof is based on the same design concept, by making a supporting structure with wooden beams or trussed rafters with additional materials on the sides and filling the gaps with thermal insulation.

Indoor finishing

From the outside, a building constructed with timber framing technology can be finished with laying clinker tiles, siding, or by laying an additional layer of insulation with decorative plaster. Construction consists in joining the boards into wall panels using nails or metal connectors and then setting the walls vertically.
Currently, the company plans to launch houses that have solar power installed. This will allow customers to reduce maintenance costs and have more freedom to choose the location of the house.

A few words about wood...

Type / grade

For construction of the house it is appropriate to use pine (for structural elements) or spruce (for non-structural elements). Pine lumber is durable, resilient, relatively soft and easy to process. The most popular and commonly used types include those from the coniferous family (although this is not a requirement), and on the list we can find such timbers as: pine, spruce, larch, cedar, combinations with aspen, lime or oak wood.

Strength

For timber frame construction it is recommended to use K27 grade lumber (with a bending strength of at least 27MPa).

Resistance to fire

Planed structural timber is more resistant to fire than non-planed timber: flames glide across its smooth surface. Planed wood is also less likely to be infested by insects, as they have a harder time getting inside the piece through the smooth surface.
The wood is also certified with C24, which is required for structural timber in the EU. The wood is imported from Sweden because it guarantees the highest quality. Unfortunately, in Poland there is still a problem with credible sorting of lumber for structural timber. According to the certificate, the wood is vacuum chamber treated, which ensures high fire protection and appropriate strength.
