There are 6 main types of foundations: foundation benches, foundation feet, slab foundations, foundation grids, box foundations, solid foundations. From the above types of foundations, both for skeleton and heavy houses, we recommend a foundation that combines the building technologies used in two types of foundation: a foundation bench and a slab foundation.
The type of foundation is chosen according to the weight of the object and the condition of the ground on which the house is to be erected. So it would be best if the construction project was preceded by a geotechnical expertise.
The type of foundation proposed in the illustration can compensate for the low thermal inertia that characterises frame-type houses. The weight of the building is evenly distributed on the foundation benches and slabs, so this type of foundation is at the same time a good solution for heavy houses and is used on non-cohesive soils.
Wall construction is based on more than 20 building technologies. A good combination is a combination of cellular concrete (aerated concrete), Silki and Porothermu. However, this solution requires a lot of time and excellent cooperation of bricklayers, formwork fitters and armourers. Another method is SIP technology. Houses built using this method are fast-growing objects. However, it should be remembered that the time it takes to produce board elements that are consistent with the design is often two to three months or even longer.
There are only two technologies that are significantly superior to the others – „Tron” technology, which is used to build reinforced concrete houses, and „Termo” recommended by German construction technologists to build a frame house. They comply with standard WT 01. 01. 2021 and heat transfer coefficient requirements for external walls U ≤ 0,2 (W/m2K).
In the „Tron” technique, a 15 cm reinforced concrete wall and a 20 cm EPS panel with a specific thermal conductivity of λ ≤ 0. 035(W/ m-K) are used. Reinforced concrete (reinforced concrete), of which there is no doubt, is currently one of the most durable materials. The strength of the concrete allows the building to be erected with walls as thick as 10 cm to 20 cm and with floors as thick as 3 to 5 storeys. The „Tron” technology is a fast, uniform, jointless wall construction with high thermal inertia and low construction cost, which cannot be said to be the case with aerated concrete or Parothermu walls.

Skeleton house „Termo+”
The wall structure of skeleton houses consists of 200 mm thick bales and 250 mm thick mineral wool. The thermal transmittance of such a wall is U = 0. 15 (W/m2K), which is 25% higher than the standard given for 2021.
The most important advantage of this type of houses is the material from which they are built. Wood as an element of construction and natural raw material creates a unique microclimate of the building’s interior, which is difficult to create using other building technologies.
Moreover, the second advantage that can be attributed to frame houses is the short construction time. A residential building consisting of single columns and beams on site can be constructed in about three months.
The second variant, which assumes delivery of the finished house structure to the construction site in fully prefabricated elements, allows the house to be erected even in a few days. No unnecessary construction waste is generated during the construction of the frame house, as only chips can be found on site after the assembly process. They can then be buried, making them useful for the soil. DOWNLOAD -> Gosur_Sp.z_oo_-_Szkieletowe_20050.pdf)
