Boards are wood with the width cross-section more than twice the thickness and the thickness of less than 100 mm. There are two types of boards used in construction: single cutting boards or double cutting boards. Single cutting boards are obtained by cutting logs along one direction.


Beams (blocks) are wood products with the cross-sectional width less than twice the height. In practice, beams have a square or almost square cross-section, for example: 50×50, 100×120, 200×150 etc. Beams are most often used in construction as supporting structures, such as struts, columns, transoms, joists, beams, floor beams and others.

Roof timber

UAB Metalėja always offers properly packaged roof timber ready for transportation. Depending on the use, roof timber can be of different lengths. Roof is one of the most important structural and architectural parts of the building.


Double pitched rafter systems are most commonly used in private housing. This means that the main elements of the load-bearing roof structures are rafters. Most rafters are made of coniferous wood.


Purlins are used as support for roofing. Depending on the roof surface, they come in two types. If the roof is heavy (mostly tiled), it is necessary to use beams, for example: 50x50, 50×60 etc.


Joists are the outer logs of the wall on which the rafters are rested. Joists are used for equal distribution of the roof load structures on the house walls. Usually, joist dimensions are at least 100x100 mm.

Roof battens

Longitudinal purlins (battens) in the pitched roof structure are necessary for several reasons. First of all, longitudinal battens ensure adequate air circulation under the roof covering (of course, only if the roof is installed correctly). In addition, spaces between purlins and the roof film made with longitudinal batten allows condensation to drain freely.


Softfit cladding is used for covering the pitched roof that projects over the exterior wall and the gable, with small planks or boards. Typically, cladding is made of the same outdoor siding (rectangular or diamond cross-section, but not rabbet). Cladding has to be dried; most often developers want planed components, although sometimes non-planed, rough texture cladding is also good for the overall exterior and design of the house.
