Why is timber a popular choice for cladding?
Timber cladding adds a timeless, warm and natural finish to buildings, appropriate for many architectural styles, from commercial buildings to residential homes. In addition, there are some woods which have a natural durability due to its resistance to moisture, rot, decay and insects. This, paired with established weatherproofing techniques, means that timber cladding is longstanding. It is also a great option for the eco-conscious as the timber stores greenhouse gases during it’s lifecycle.
Is timber cladding a fire risk?
One of the biggest concerns regarding timber cladding is fire safety. Timber has a lower fire resistance compared to materials like brick and concrete, but it is still possible to use timber cladding safely. It is imperative to choose the right type of timber and take necessary precautions during the installation process. In general, treated timber and hardwoods have better fire resistance compared to softwoods, primarily due to their density. Additionally, fire retardant coatings and intumescent coatings can be applied to timber cladding to enhance their fire resistance.
