Alm

The elm is a deciduous tree in the elm genus. The elm can grow up to 40 m high, and has grey bark that often cracks on older trees. In recent times, elms have been seriously threatened by 'Dutch elm disease'. This disease, caused by a fungal species, has almost wiped out elms from large parts of the continent.

Elm is a sought-after wood species in furniture and interior production, used both as solid wood and veneer. Elm wood is dimensionally stable and has good resistance to fungal decay. Elm was traditionally used in buildings near and in water as water pipes, water wheels and in ships. 

Ask

As wood, ash is used in the manufacture of furniture, carpentry, parquet flooring, but also for the handles of travel cabinets and oars. Ash wood is strong, hard and tough and has particularly good breaking strength under shock loads. This makes ash well suited for travel cabinets and tool handles, especially for percussion tools. In the past, ash was used for skis and poles because of its toughness and strength. It is a light-coloured material with a coarse structure, nice large grain patterns in tangentially cut timber, and fairly straight with 3-4 mm grain spacing in radially cut timber. Ash is slightly prone to darker stains: false heartwood. The wood otherwise has no visible heartwood, but is monochrome in colour. Ash is a heat-loving tree species that grows best in deep, calcareous and mouldy soil with fresh moisture.

Oak tree

Oak wood is strong and hard and is widely used for building structures, flooring and furniture. Oak wood is highly resistant to rot. Its beautiful texture and colour have made it the most popular wood for the production of parquet flooring. There are also laminate floors with a melamine pattern layer that mimics the texture and colour of the wood, but does not contain oak wood. The wood is golden with shades of yellow and light brown, sometimes with a slight hint of red. In the past, oak trees were highly sought after for shipbuilding and the oak population in Norway was therefore heavily taxed until the 1900s.
