WOOD AS A BUILDING MATERIAL:

BENEFIRTS:

1. Wellbeing. Wood is very warm material. Massive wood has a great warmth capacity. In summer the atmosphere is pleasantly calm and in winter smoothly warm.
2. Appearance. Wood is beautiful material. Natural forms and colours. Natural surroundings bring up creativity.
3. Ecology. Wood is a renewable resource and using it supports the global sustainable development. As a tree grows it binds carbon dioxide to itself and slows down the global warming on its behalf. The materials of a genuine wood house are recyclable after decades.

Forest is a wood factory which produces wood using only solar energy. In processing and production , wood requires far less energy than other building materials.

4. Economy. Wood is an inexpensive material.

PROBLEMS:

1. Fire.
2. Durability.
3. Design limitations.

ENGINEERED WOOD

Engineered wood, also called composite wood, man-made wood, or manufactured board; includes a range of derivative wood products which are manufactured by binding the strands, particles, fibers of wood, together with adhesives, to form composite materials. These products are engineered to precise design specifications. Engineered wood products are used in a variety of applications, from home construction to commercial buildings to industrial products. The products can be used for replace steel in many building projects.

CLT (cross-laminated timber)

Is a product used in prefabricated construction. Spruce boards are technically dried in modern factories and glued together crosswise with a minimum of three layers.

MANUFACTURE:

1. Cut spruce tree
2. Select trunks
3. Cut in planks
4. Do finger joint union
5. Glue the cross-laminate timber boards
6. Put wacuum pressure on the panels

BENEFIRTS:

WHEN PLANNING

• Free planning without being bound to one grid, using approved building materials in the largest dimensions

• A high level of pre-fabrication facilitates reasonably priced simple building

• The simplest building component construction and detailed planning

• Heat-, sound- and fire-proofing combined in one building component

• Minimum planning risk due to detailed planning documents

WHEN BUILDING

• The shortest building times

• Economical building due to large elements

• Exact superstructure due to accurately fitting building components

• The simplest, prepared connections

• Only one type of joints or fasteners required

• Problem-free interior work

• Minimum sealing work required and high level of airtightness due to low number of joints

• The simplest handling of elements due to integrated fitting aids

WHEN CONSTRUCTING

• Identical elements for all applications (wall /ceiling / roof)

• Bracing building components, no extra bracing measures required

• The option of bridging wall openings at room height without lintels using LenoTec ceiling boards

• Biaxial load relief with floor elements

• Building components support and create space at the same time

WHEN LIVING IN LENO MASSIVE CONSTRUCTION

• Long-lasting, solid wooden construction

• Ecological, CO2 storing material

• Building component construction vapour permeable

• Pleasant, warm living climate due to solid, moisture regulating building components

• Up to 15% more living area compared to alternative types of construction due to slim constructions with the best thermal insulation

• The best tried and tested sound-proofing results

• High level of thermal insulation due to heavy building components

LVL (laminated veneer lumber)

Laminated veneer lumber (LVL) is an engineered wood product that uses multiple layers of thin wood assembled with adhesives. It offers several advantages over typical milled lumber: it is stronger, straighter, and more uniform. It is much less likely than conventional lumber to warp, twist, bow, or shrink due to its composite nature. Made in a factory under controlled specifications, LVL products allow users to reduce the onsite labor. They are typically used for headers, beams, rimboard, and edge-forming material.

MANUFACTURE:

1. Cut spruce tree
2. Select trunks
3. Rotary pile get 3mm veneers
4. Glued together lengthwise

BENEFIRTS:

The same + no design limitations.
