Log building was and still is a popular individual housing wall construction type in the Latvia and around the world. One of the most topical issues of log buildings long-term use is log insulation, therefore, in Latvian and other European countries the additional heating is used due to climatic conditions 6-9 months of the year on a daily basis, thus it is essential to improve the heat insulation features of the building.
Log wall heat transfer coefficients are higher than the normative LBN-002-01 maximum U=0/31 W (M2.K). Usually, these heat losses through the walls are compensated by other enclosing structures with better heat-resisting features. So we choose external wall insulation.
Using the external wall insulation:
1. a continuous insulation layer is formed without partition, intermediate division and other structural indicators of cold bridges
2. the outer wall bearing construction is protected from climatic conditions
3. array is located inside and it has large thermal inertia, so accumulated heat in the wall is held longer
4. there is no need for any preparation
5. there is no need to install a vapor barrier
6. an indoor area is stored
Heated log buildings` walls we produce have been tested in the "Environmental and technological mathematical modeling laboratory".
The wall thickness of 160 mm and insulation of 150 mm U=0.2W(m2k)
The wall thickness of 120 mm and insulation of 150 mm U=0.21W(m2k)
The wall thickness of 80 mm and insulation of 150 mm U=0.22W(m2k)
