Hundegger joinery machine

Polar Life Haus purchased the first Hundegger joinery machine as early as in 1998. In 2008, we made another investment in quality and purchased the Hundegger K2i joinery machine, at the time the first of its kind in Finland. In 2012, the latest model of K2i followed in tow. Hundegger machines are used for manufacturing all pre-cut ecohomes, a number of especially demanding joints in log homes (city corners with dovetail joints, slanting corners, T-corners etc.) as well as all rafters and laminated beams. Hundegger guarantees machining accurate to the millimetre and makes it possible to realise even the most demanding architectural solutions.

Sorting

All wooden material goes through strict sorting at our factory. This way, we can ensure the high quality of the raw materials that are used for house kits. Only the best quality raw materials pass the sorting, making this a very important step in terms of quality control.

Drying

All wooden material used in the house kits is dried at our factory. The drying technique that we use represents the most modern technique in the wood processing industry. Our automated systems monitor that the drying conditions are correct day and night (humidity, temperature etc.). This ensures the quality and durability of the finished product, and that the logs will not twist or crack.

Gluing line

Laminated logs and beams are made of smaller lamellae that are glued together. Our modern gluing line guarantees that all glue joints are of the first class, both in terms of durability and aesthetics. The gluing process starts with planing, which “opens” the surface of the wood, so that the glue can penetrate deep into the cell tissue of the wood. As a result, the glue joints are extremely stable, ensuring the high quality and longevity of our houses. The adhesive we use is a completely formaldehyde-free Swiss solution called Purbond. A Finnish Notified Body Finotrol Oy regularly surveys our production and grants us the permission for producing laminated timber.

Finger jointing line

Extra-long logs and laminated beams are made by finger jointing shorter pieces together. Small “fingers” are cut in the ends of the pieces, which are then joined together with glue. Finger jointing is a way to make the joints extremely strong. There are a number of different methods for making finger joints, but the technology that we use guarantees that the joint is safe and the finished product has a clean and elaborate look.

Log planing

Polar Life Haus log homes are made combining the latest technology with traditional craftsmanship. As the surface of logs often remains a visible part of the interior decoration, the quality of planing becomes immensely important. In order to give logs a smooth and even feel, the planing process is a seamless combination of handwork and machinery.

Corner notches

One of the most important aspects in the quality and functionality of a log house is the tightness and stability of the notches. The notches of a Polar Life Haus log home are made on a fully computer-controlled notch line, where the joints are produced according to the programming made by the constructional designer of the house. The Computer-Aided Design and Manufacturing system enables the flawlessness and quality of the notches. Before starting the production, also a so-called model notch is made in order to “double check” that everything fits together perfectly.

Panel plane

All panels included in the house kits are planed at the factory: roof and wall panels, floor boards etc. Similar to logs, the quality of the surface that the panel plane leaves on the panels is one of the most important factors in the overall quality of log and wooden homes. In order to achieve the best possible result, attention must be paid to the correct humidity level of the wood, the sharpness of the cutters as well as correct planing speed.

Packaging and delivery

All products are carefully covered with UV-protected plastic. The bottom of the packages is left without plastic so that air can circulate and there will be no humidity damages. The ready-made packages wait in our loading area normally only a few days for the delivery, after which the packages are loaded into trailers, or in special export deliveries into containers. In container deliveries the logs are treated with a special protective treatment because of changes in humidity and temperature during delivery.

Top technology and strict quality control

We invest in quality at every stage of our production – from the quality of the raw material until the finishing planing of the panels. Our latest investments include the latest model of the Hundegger K2i joinery machine and our renewed production line for laminated logs. We produce laminated logs and laminated beams with a unique Rotoles technique, which is a special method to open the cell tissue in the planing phase. This way, the glue goes deep into the cell tissue of the wood and the glue joints of the logs and beams become tight and secure. The result is a high-quality laminated log with glue joints that do not crack open.

We control the whole production chain from the very beginning to the end, which means that we produce all wooden parts required for the houses at our factory. This makes seamless quality control and product development possible. The unique Softline profile of the logs and our post&beam construction are examples of the results of our product development. We wish to offer our customers only the best.
