The benefits of using lime to create a vapour open construction are well known for historic solid walled buildings, however its use in modern construction is not so well documented.
Steico produce both wet and dry process boards. What is the difference ?
Wood processed into STEICO wood fibre insulating materials delivers truly outstanding performance. The wood fibres create tiny air pockets within the insulation boards providing proven excellent insulation performance wood fibre insulation is ideal for the construction of state-of-the-art energy-saving buildings or for energy saving renovations.

For the past 150 years modern artificial cements have slowly been replacing traditional lime based mortars and plasters, to such a degree that now virtually all construction is carried out using only modern materials. Whilst many of these materials are perfectly suitable for modern buildings they have been found to be incompatible with the construction of old buildings.
The purpose of this operation is to remove either old and deteriorated pointing/bedding mortar or modern cementious mortars that are causing damage to the building fabric.
Lime Protection, Curing and Aftercare is a vital process in the successful use of lime mortars.
