Lapponia House is the original pioneer in thermo log contruction since 1976
Advantages of Lapponia Thermo Log construction
• Technically advanced, modern Thermo Log home with appearance of a traditional log home and with technical benefits of best timber frame houses on the market
• Wall construction does not settle down nor crack as traditional log wall does
• Saves you from a later re-adjustment of doors and windows, which is necessary in traditional log homes
• Makes it also possible to use unlimited variations of wall cladding materials (wall paper, paint or ceramic tiling) inside
• Meet the warmth and insulation requirements for energy-save houses by a broad margin
• Secure optimal energy use and warm comfort during cold winter months
• Saves also energy used for air-condition
• Loss of heat of exterior wall is illustrated with u-value. Lapponia wall construction has three times better value than traditional log wall. 170 mm Thermo Log wall, u=0,22 W/Km2 versus traditional 210 mm round log wall, u=0,67 W/Km2. In the 120 mm Thermo Log wall, u=0,31 W/Km2
• Ecological and forest saving; several Lapponia Thermo Log homes can be built of of the wood used for one solid log home
• The ventilation gap under outside cladding of exterior wall keeps the wall structure dry in all weather conditions
• Manufactured in modern and ideal factory conditions
• Large prefabricated exterior wall units with ready installed windows ensure short construction time at site
• The production line in the factory is controlled by VTT, Technical Research Centre of Finland
• The materials used in Lapponia Thermo Log walls are examined to comply with DIN 1052 (Deutsche Industrie Normen)
CLT Cross laminated timber
Cross Laminated Timber (CLT) consists of cross-glued board layers. There are several layers, usually three or five. In this way, a very durable, very strong and rigid construction board with a lightweight construction is formed.
The boards can be used as load-bearing and rigid structures in both walls and floor structures. Indoors, the plates can be coated or, if permitted, the fire rules will be left unaltered, depending on the purpose sought. Dimensionally strong and rigid panels can be used to work differently in different building elements. The windows and doors in the facade can be placed very freely, and the angular windows can also be successful because the plate-like structures function as projections if necessary.
In exterior walls, the plates are insulated in the normal way. The insulation is placed outside the plate. In substrates, the boards are usually used as a joint structure together with concrete casting, whereby the wood acts as a fire protection structure, massive concrete or plaster casting isolates the sound and the load capacity is achieved as a composite structure. For items where no sound requirements for floor sound insulation have been set, plates can be used without concrete casting. The joining structure can also be replaced by floating floor layers and the sheet is stiffened with beams.
The use of CLTs is very popular in Central Europe where users are accustomed to massive structures.
