In-situ repairs are necessary when timber components in a structure are no longer safe or serviceable for their intended purpose. They can also restore the appearance, performance, and functionality of timber.
To keep wood products in an appropriate condition for installation and to protect workers’ safety and health on site, some simple guidance is provided in this knowledge sheet.
Preservative treatment provides wood with added durability (against decay and insect attack). But, it’s a mistake to assume that all treated wood is the same. The level of preservative protection required depends on where it is to be used.
In some cases, it is possible to classify untreated wood-based products without further testing as long as these products meet the requirements set out in the relevant harmonised technical specification.
Flame Retardant (FR) chemical treatments for timber work by reducing its ignitability, slowing down the surface spread of flame and, as a result, reducing the heat released. This allows more time for escape in a fire situation.
The European LVL industry (Metsä Wood, Pollmeier Massivholz GmbH & Co. KG, STEICO SE and Stora Enso) has decided to launch LVL strength classes. This bulletin introduces the classes along with other product and design provisions not yet covered in the respective standards.
This European LVL Handbook serves as a guide for architects, structural engineers, technical wholesalers, off-site element manufacturers, contractors, carpenters and other construction professionals, and as an educational resource. The handbook has been prepared by the Federation of the Finnish Woodworking Industries during 2018-19.
