Log house technology

Production and values

Villa-W-450

Palmatin is a production company that values an eco-friendly and healthy living environment.

With these values in mind, we have organized our production in a way that will leave our future generations with a worthy living environment. To move towards this goal we have implemented waste-free production and we use FSC® (C-108038) certified materials in our products to contribute to the sustainability of the environment.

The house factory is situated in Estonia on a 5 ha plot, where we have over 12 000 m² of production and warehouse area.

In our 17 active years we have made over 1200 houses. The export capacity of the factory and the ability to offer our clients suitable solutions have been of the utmost importance throughout our active years. Today 87% of our production is exported to other European countries; also to more far-away locations like Japan, USA and Panama.

Offering our clients suitable tailored solutions has inspired us to develop new solutions and use modern technologies in their realization. As a result, today we can produce many different constructions for our clients.

With this we hope that customers with even the most special wishes will find a house solution of their liking from our product range which includes solid and Glulam log houses, Post & Beam houses, Pre-Cut houses and prefab houses.

To guarantee a client based and smooth production, we have undergone the certification of quality management systems according to the ISO 9001:2008 standard.

All products manufactured for our clients, whether it be a wall log or window border, are made of high quality and highly valued northern wood. The high quality of the raw materials is one of the pillars of our production, because a good end result can only be achieved by using the best raw materials.

We use modern automatic CNC production lines, which efficiency guarantees the best value for money.

Log profiles

To provide you with the wall material of your liking, we have developed a wide range of different solid and Glulam log profiles.

Palmatin product range includes 31 different log profiles either from spruce or pine material.

Glulam timber

liimpuit-pilt-3d-1024x671

To offer modern solutions, we manufacture Glulam logs and beams in many different dimensions.

We produce glulam logs and beams in many different sizes starting from a 88x180mm 2-piece log to a 272×310 mm 8-piece log with square logs and from a 150 mm 3-piece log to a 300 mm 10-piece log with round logs.

The height of large glued laminated beams can be up to half a meter. We use a computer-driven production line for the manufacturing of Glulam timber.

All Glulam materials used in Palmatin’s log houses are manufactured at our factory.

“City corner”

linnanurk1-1024x768

The „City corner“ gives us continuous possibilities to build square log houses in the city and urban areas.

The „City corner“ solution does not leave the log house with characteristic cross corners i.e. there are no protruding log ends.

This kind of solution gives the log house a similar look to other houses in the urban area that have a wooden façade and therefore the log house will fit well with the area’s architecture.

Dovetail joint

kalasabatapp-1024x382

The dovetail joint is used when a detail has to be connected in crossing detail with a mortise.

For example crossing log walls are connected by a dovetail joint if the client does not wish or it’s not structurally possible to use the classical cross corner.

Different angles

mittetaisnurkne-nurk-2-1024x685

If before you could only use rectangular shapes in a house floor plan, then now by using our new technology we can offer rooms with over or under 90 degree corners.

This means you can choose floor plans that have polygon or octagonal (or any other shape) rooms that weren’t possible before.

Over 6 Meters Long Details in a Log House

sormjatk-1-1024x885

Typical raw material length is 6 meters or less, so to meet our costumers’ wishes, we offer two different types of log lengthening opportunities – finger jointing and dovetail jointing.

The difference between the two methods:

  • With finger jointing the materials are glued together at the factory and transported to the construction site in full length – log length is limited by transportation.
  • With dovetail jointing the materials are milled in the factory, but assembled at the construction site – log length is not limited by transportation.

Thanks to the log lengthening features we don’t have any problems offering our clients log house designs exactly the way they want them.

Using finger jointing in wall, ceiling and roof construction materials allows us to engineer and build spacious and roomy log houses thanks to using large spans.

Double exterior wall

erineva-paksusega-seinad3-1024x530

Double exterior wall, where extra insulation is installed between the two parallel walls.

The space between the two walls can be adjusted according to the desired thickness of the insulation.

This double exterior wall solution ensures even higher energy efficiency and helps to bring the heating costs to a minimum.

 

Using walls with different thickness in a log house

Using this kind of solution offers many positive results.

Using thinner interior walls gives more useful floor space.

This allows to save money in the price of the walls and also with internal doors and building costs.

Extra insulation

extra-insulation-joonis

We offer a special extra insulation system for our log walls.

Using this solution on the exterior side of the wall allows you to cover the walls with a material of your liking and adding an extra layer of insulation between the wall and exterior façade.

“Pre-Cut” House

Pre-cut-ehitus-1024x680

“Pre-Cut” House – a ready for installation construction that has been pre-cut, mortised and marked in the factory.

The “Pre- Cut” solution can be used for interior walls of a log house, first floor walls or roof construction.

Using such processed and labelled details enables experienced specialists to assemble the wooden frame of an average sized residence in 3-4 days.

“Post&Beam”

Villa-W-450

This solution offers a strong construction, made by combining Glulam posts and beams.

The post and beams are usually connected by a dovetail joint, but also other connections are used that can ensure sufficient stiffness to the construction.

After completing the main frame of the house, the openings between the posts and beams are filled with materials of your liking (for example glass or wooden details)

Certified Eco-friendly Production

DSC_0477-Copy-647x1024

We value an ecologically friendly and healthy living environment. We have organized our production so that we would leave a healthy living environment to our future generations.

Aspiration system and production without waste

We follow environmentally friendly principles by keeping production waste at a minimum, which also reduces energy usage. All wood production waste is collected and put into the wood chipper. We use the sawdust for heating the factories and Kiln driers.

We have invested in an aspiration system which prevents the sawdust and heat being thrown into the environment.

Internationally Certified Glue

Purbond-logo-21

Purbond glue used in our Glulam logs is in line with our values, because it also focuses on eco-friendly production, and healthy living environments.

Purbond glue used in our laminated logs has many great features which makes it the best solution for us.

Formaldehyde-free – The adhesive system uses the natural moisture of the wood to join timber parts together. This is done without any solvent and the glue does not emit formaldehyde, making the glue toxicologically safe.
Stable – Years of experience with polyurethane materials in different fields have shown that once the glue has dried, it is completely inert and will not react further with substances in the environment.
Cost-efficient – The Purbond adhesives conserve resources, because less adhesive is needed than with alternative solutions. Using the new automated gluing system we guarantee optimal usage of glue and shorter drying time, resulting in better Glulam log prices.
No waste – The adhesives are applied directly from the can to the joints of the timber parts. No mixing is required, and no effluent is produced.
Natural and healthy – The comparability of natural solid wood and wood processed with formaldehyde-free polyurethane glue has been confirmed by a report from the Fraunhofer Wilhelm Klauditz Institute in Germany. Purbond helps us keep the natural qualities of the wood.
Purbond glue is internationally certified. Using Purbond adhesives in the production of wood products has been approved under DIN 1052 and Eurocode 5.

Materials we are using

kvaliteetne-materjal-1024x696

We use Northern wood to ensure the steady high quality in our products. We offer solid and Glulam timber for our houses, either from pine or spruce wood.

We offer the following certified materials:

FSC® (c-108038) certified – We are able to offer FSC® certified materials in our products and we have undergone FSC® certification, which means that our material handling has passed the certification and as a result we have the right to sell Palmatin’s FSC®-labelled materials.

Strength graded construction timber

We also make long details by finger jointing; the only limiting factor is the length of the transportation.

Terrace and balcony wooden materials (boarding and joists) are impregnated.

All wooden materials used in Palmatin’s log houses are manufactured at our factory, the materials are Kiln dried, calibrated or planed, cross-cut, marked and packaged.

Design and Engineering

HSB_Print-screen2

For every construction it is important to have an accurate, engineered project where even the smallest details are taken into account.

Palmatin engineers have more than 10 years of experience in engineering log and wood houses. We like to take the maximum out of a project, so that there will be no waste of materials. For every project we calculate static and other important standards.

In cooperation with Tallinn Technical University we have created a special computer program to help with the designing process of log homes.

Projects are made by using CAD programmes, such as AutoCAD, ArchiCAD, hsbCAD, etc. Our production lines are in network with engineers’ computers so that we can send all the information about the house directly to machine which will start to produce the details of the house.
