Superior quality and special properties
Logs of Ollikaisen Hirsirakenne are made from first class timber. Our selection includes versatile range of traditional massive logs and technically excellent laminated logs. Thanks to woods special capabilities, it is a pleasure to live, work and relax in genuine log building, as log construction breathes and thus creates a healthy environment. This unique breathing construction keeps log house warm in winter and pleasantly cool in summer. Logs compensate indoor humidity by binding and releasing it, along with changing weather conditions and seasons. Log homes are proven to be allergy-friendly, thanks to great indoor atmosphere.
Excellent accuracy
We design and product our logs with modern CAD-CAM system to guarantee supreme dimensional accuracy and quality. Our advanced double-lock log profile is the result of our long and continuous products development and experience. This unique log profile forms tighter and more energy efficient wall structure compared to competitive solutions.
Laminated but green
Laminated log consist of two or more layers that have been joint together in a way that hard heartwood lies in surface of the log beam. Laminated log is almost unyielding and non-cracking. During the last two decades that laminated log has been in manufacture, the bonding techniques have experienced revolutionary advances. With current peak-milled manufacturing technology and with modern PUR-adhesive compound, our laminated logs are nearly environmental as our massive logs have always been. Today’s advanced adhesive compound allows wood to breathe naturally, as massive logs do, maintaining a comfortable indoor temperature and humidity.
Incredible energy efficiency
Our new Super logs meet the Finland’s strictest energy efficiency standards set into force in 2010 and best of all, without synthetic insulation. Super log forms breathing and environmentally friendly wall structure with incredible energy efficiency. Alternatively, the energy requirements can be met in narrower logs by using additional insulation. Energy efficiency requirements vary by country. Check the current requirements from our local building authority.
Round logs
Only difference between round and square logs is appearance. Round log has extinctive traditional look and it is widely used in log cottages, summerhouses and sauna buildings. Massive logs are made from single beam. When log beam dry up small cracks are will form to its surface. Cracks don’t penetrate log beam and have no effect to thermal insulation capabilities. Our selection includes massive and laminated round logs ranging from 150mm to 230mm.
Square logs
Straight surface of square log makes it suitable for modern day architecture by combining contemporary looks and long log building traditions. Our selection covers massive and laminated square logs ranging from 94mm up to 270mm super log. Log seams are generally insulated with linen ribbon that is also natural product. Linen seam insulation is part of our basic delivery but if preferred we can offer polypropylene insulator as an option.
The green choice
Together with natural stone, wood is only 100% natural building material available. Besides proven ecological, log is unique, beautiful, versatile and enduring. We believe in sustainable development. Our goal is to ensure that our actions do not post unnecessary burden to the environment.
