Rainscreen façade cladding is an excellent way to protect your building from the elements. They're easy to install and maintain and used for newly built projects, as well as for refurbishments. A popular choice of material for many commercial and private projects, timber offers sustainability and effectiveness.
Larch in particular makes excellent rainscreen cladding timber due to its natural properties such as resilience, insect resistance, and scratch resistance. Luxury Wood offers several convenient choices in this category.
What is rainscreen cladding?
Rainscreen (a.k.a. rainshield) cladding is an outer layer attached to a building, intended to protect it from harsh weather conditions such as snow, rain, wind, frosts, and sunlight. It sits away from a building's exterior wall, creating a protective air cavity.
What makes rainscreen cladding systems effective?
A good rainscreen needs to control and manage nature's elements. Thus, it has several components: cladding, vented air space, insulation, air barrier, and the bearing wall of the building. The vented air cavity promotes residual water drainage and airflow behind the wall panel. The insulation on the exterior side of the air barrier decreases the heat flow. The air barrier is meant to stop any residual amounts of water that bypass the external cladding by letting it drain or evaporate. Vertical rainscreen battens that have channels allow cross-ventilation between the cavities.
What types of rainscreen cladding are there?
There are three types of systems:
- Vented and pressure-equalised: Used on tall commercial buildings. They prevent moisture from entering into the air gap between the façade and the internal structure. This is done by sealing the top section of the façade and creating separate ventilation cavities.
- Drained and vented - Feature an open cavity at the top (protected with an overhang) and one at the bottom. They provide drainage and a moisture barrier is used to protect the building.
- Vented: Used for building 1-4 stories high. A cavity open at the bottom of the façade provides drainage but no ventilation. The warmth in the cavity helps water condense and drain.
