Previously, log houses could only be built with settling compensation. This meant that large glass fronts and windows could only be realised with elaborate structural measures. The same applied to the gable area and connections to brick structures and uprights.
The time had come to eliminate these disadvantages and realise the vision of log-house walls that didn’t settle. The particular challenge was to develop the appropriate manufacturing methods.The central approaches taken were, on the one hand, to utilise the very good structural properties that wood possesses along its grain and, on the other hand, to maintain the typical appearance of wood.
After much development work, we became the first company to find a technical solution for commercial mass production. The solution integrates the wood and its stabilising properties along its grain into the inside of the log-house plank. This ingenious method guarantees that the structure won’t settle and preserves the desired appearance.
A special tongue-and-groove profile allows Bilam forte to naturally also satisfy the high demands made in modern, energy-aware construction. Weinberger supplies Bilam forte in thicknesses up to 200 mm and in rises up to 200 mm (other widths and heights available on request).
The special property of the Bilam forte thermo-spruce log-house plank that doesn’t settle lies in its hybrid structure. Some additional timber properties and product advantages are the result of the combination of untreated spruce wood on the inside and thermally-treated pine wood on the outside. The thermal treatment takes place without chemicals and only using very hot steam.
This natural thermal finishing of the outer lamella changes its colour depending on the temperature that is used. The wood gets a warm, brown, caramel-like colour, but at the same time retains its lively and contrasting marking including the growth ring structure. The higher the temperature during the thermal treatment, the darker the brown colour.
Warm brown or elegant grey
Bilam forte thermo-spruce from Weinberger scores top points with a high resistance to rotting due to decay and fungal infestation. It is also resistant to longhorn beetles. In short: Bilam forte thermo-spruce is even more durable. Because the thermal treatment of the timber affects not only the surface but penetrates the entire material.
Bilam forte thermo-spruce will convince you right down the line with just as good a form and dimensional stability as Bilam forte that has not undergone thermal treatment. And naturally under fluctuating moisture conditions too. What’s more, it has been proven that thermally treated timber conducts heat far worse than untreated timber. This means that Bilam forte thermo-spruce offers even better insulation!
Bilam forte thermo-spruce from Weinberger is a product of nature. Because the timber only undergoes thermal treatment using hot steam without any chemicals. It contains exclusively renewable resources that can be disposed of in an environmentally appropriate way. Thus, offcuts can simply be burnt. In biomass power plants, for example!
