Massive wooden logs are a beautiful, ecologically-friendly material that give your house a uniquely warm and welcoming feeling. Log houses are comfortable and healthy to live in all year round, and Kontio log houses in particular have many special properties which make them a strong, safe and long-lasting choice.

Kontio is the world’s leading log house company. We have 50 years’ experience of working with massive wood, making premium healthy log buildings and developing innovative construction solutions. And we call our accumulated engineering knowhow Kontio Woodhow™.

Every Kontio wood house is built using Kontio Woodhow™ and each one is a combination of our engineering expertise and the highest quality materials and components. Our wooden houses are equipped with industry leading innovations like high-tech log profiles, our double sealing solution, superior jointing technology, innovative corner designs, and Kontio SmartLog™ logs. We construct them using our unique Kontio Arctic Pine™ wood, which creates a solid foundation for durable and healthy homes.

Energy Saving Smart Design

Kontio comes from close the Arctic Circle where houses have to withstand very cold winters. Over hundreds of years massive pine logs have proven to be an excellent construction material for these conditions. The massive logs even out temperature variations, so that log houses stay cool in summer and agreeably warm in winter. And, in the northern hemisphere, where the sun shines at a low angle, the solid walls also collect and store energy from the sunlight during autumn and spring.

Modern Kontio log houses incorporate Smart Design™ with our advanced technical solutions to let you live in comfort in all seasons, anywhere in the world, and they are designed to be energy efficient, even in extreme conditions.

Energy Efficient Technology

Kontio log houses are carefully designed to fulfil the energy efficiency requirements of today’s residential housing. We choose the best structural solutions to meet the demands of low-energy construction including log type, corner design, sealing technology, window glass, air ventilation and heat recovery systems, as well as additional insulation.

The thermal insulation capacity and the U value of walls can be improved using an additional insulation structure. This can be installed on either side of a log wall, and it can also be coated with alternative surface materials to create a variety of attractive interiors and facades.

Our buildings are engineered to ensure your safety

Kontio log structures have been tested against fire and have high fire resistance classification values. The classification system is governed by international testing methods and standards.

Although timber is a combustible material, in construction it performs well against fire. The good fire resistance feature of logs comes from the nature of the material: the natural humidity in wood protects it from ignition. Before the wood can ignite, the humidity must be evaporated. And in cases of fire, the burnt surface and charring of the wood actually slows down the spread of the fire.

Kontio log houses have resistance to fire values of up to REI 90, with R up to 120.

Earthquake Safe

Kontio log houses are an ideal choice for seismically active areas. Log houses exhibit superior seismic endurance and the elastic nature of wood, combined with horizontal log construction, makes them the safest choice in tremor prone areas. For decades, customers from seismically active regions such as Japan, Central Asia and Southern Europe have relied on Kontio’s engineering expertise and log construction technology to provide safe housing in challenging areas.
