What is a rainscreen facade?

Last Updated: 17th February, 2020

Rainscreen. A rainscreen (sometimes referred to as a 'drained and ventilated' or 'pressure-equalised' façade) is part of a double-wall construction that can be used to form the exterior walls of buildings. Rainscreen cladding systems were first investigated in the 1940s.

Similarly, what does rainscreen mean?

A rainscreen is an exterior wall detail where the siding (wall cladding) stands off from the moisture-resistant surface of an air barrier applied to the sheathing (sheeting) to create a capillary break and to allow drainage and evaporation.

Similarly, what are the benefits of a rainscreen? A rainscreen system affords architects, designers and builders numerous benefits in moisture-management and energy-efficiency, including:

  • Weather-resistant barrier support mechanism keeps moisture away from the wall assembly.
  • Water vapor behind cladding and insulation can escape by means of evaporation, avoiding mold.

Simply so, what is rainscreen cladding made from?

Rainscreen cladding is an outer layer of water-shedding material that is often placed on the outside of commercial buildings. The cladding panels can be made from different materials such as aluminum, zinc, copper and stainless steel, and they are composed of two different layers.

What is the difference between rainscreen cladding and curtain walling?

The primary difference between the two types of glass cladding is that curtain walling is usually the whole building envelope, which is the physical separator between the conditioned and unconditioned environment of a building. Rainscreen cladding is just the outer protective layer of the envelope.

Do I need a rainscreen?

So, the reason you might want a rainscreen on your new house is to help manage moisture and protect our house from water damage. A rainscreen helps to keep the sheathing and the back of exterior siding dry when they get soaked with rain. The rain screen gap also allows moisture to evaporate.

What is rain screening?

A rain screen is a space rainwater and condensation that penetrate a building's outer cladding can escape from, instead of seeping through to the inner framing, causing what's known as the leaky-condo phenomenon.

What is a barrier wall?

Barrier Wall
As the name implies, this term is commonly used to describe any exterior wall system of assembly that relies principally upon the weather-tight integrity of the outermost exterior wall surfaces and construction joints to resist bulk rainwater penetration and/or moisture ingress.

How much does rain screening cost?

The cost install a rainscreen is quite high, and will often be paid for through special assessments to the owners (which can be $5,000 to $100,000 or more per unit). 2. Install the rainscreen moisture barrier on the walls and balcony's.

Why is cladding used?

Cladding is the application of one material over another to provide a skin or layer. In construction, cladding is used to provide a degree of thermal insulation and weather resistance, and to improve the appearance of buildings.

How does a rainscreen work?

A rainscreen uses an exterior surface – a cladding layer – to break the force of sideways, wind-driven water movement, so that any water that gets through the small breaches in the surface has lost its momentum. Most water simply bounces off the surface or runs down the exterior.

What is a rainscreen cladding system?

Rainscreen cladding is the attachment of an outer skin of rear-ventilated cladding to a new or existing building. The system is a form of double-wall construction that uses an outer layer to keep out the rain and an inner layer to provide thermal insulation, prevent excessive air leakage and carry wind loading.

What is a curtain wall system?

A curtain wall is defined as thin, usually aluminum-framed wall, containing in-fills of glass, metal panels, or thin stone. The framing is attached to the building structure and does not carry the floor or roof loads of the building. Custom walls become cost competitive with standard systems as the wall area increases.

How is rainscreen cladding installed?

The rainscreen cladding system is made with a bearing wall, an insulation layer and a cladding material that is fixed to the building using a supporting structure. Thanks to this structure, an air cavity is created between the load bearing wall and the cladding material, allowing continuous ventilation.

What is timber cladding?

As the name implies, timber cladding is a method that is utilised to clad buildings or establishments to create a more beautiful finish. Technically, it is meant to protect the walls against moisture and the penetration of air. Timber cladding is sometimes referred to as weather boards or weatherboarding.

How thick is a glass curtain wall?

By far the most common glazing type, glass can be of an almost infinite combination of color, thickness, and opacity. For commercial construction, the two most common thicknesses are 1/4 inch (6 mm) monolithic and 1 inch (25 mm) insulating glass.
