The roof battens are the key element of the pitched roof structure, to which the roof covering is attached. These wooden prisms have a square or rectangular cross-section and are installed on the roof structure, usually perpendicular to the rafters, i.e. the main supporting elements of the roof.
The role of roof battens cannot be underestimated. If not properly installed on the roof, the roofing would be unstable, which could lead to leaks, reduced roof life and potential safety issues.
The difference between lats and contralatts
Lats and contralatts are often confused, but they have different functions:
- Counterlatts: These wooden prisms are installed along the rafters and serve as a support for the roof battens. Their main function is to separate the roofing material from the roofing film, thereby preventing its damage and ensuring proper roof ventilation. The standard cross-section of contralats is 4 x 6 cm.
- Roof battens: The battens are fixed perpendicular to the counter battens and the roof covering itself is attached to them. Their cross-section is usually between 3 x 5 cm and 4 x 6 cm, which depends on the type of covering, the slope of the roof and the climatic conditions. The correct spacing and cross-section of the roof battens are key to the stability and functionality of the roof.
Selection and installation of roof battens
The right choice of roof battens is essential for a successful roof installation. It is best to use dried wood to prevent warping of the slats after installation. The battens must be accurately measured and correctly placed to ensure the stability of the covering and to allow proper ventilation under the roof.
Proper spacing of roof battens
Incorrect determination of the spacing between roof battens can have serious consequences. If the spacing is too small or large, the roofing may not sit properly in place, which can lead to instability of the entire structure. Therefore, it is important that the roof installation is carried out by experienced professionals who will ensure that the roofing is firmly and securely fixed.
Roof battens play a vital role in the construction of the roof, and their correct installation is the key to the long-term functionality and safety of the entire roof.
