Six Benefits of Rainscreen Cladding Façades

Six Benefits of Rainscreen Cladding Façades

Rainscreen façades have been around for decades, but advancements in sustainability, energy-efficiency, and design flexibility have propelled their popularity to new heights. 

While already widely seen throughout Europe and Canada, American designers and builders are now reaping the benefit of modern rainscreen developments. As a globally trusted, sustainable brand, Fundermax has been around for over 100 years and remains on the front lines of these exciting developments.

What Are Rainscreen Cladding Façades?

A rainscreen system includes multiple components that work together to primarily prevent moisture infiltration. Historically, a rainscreen façade referred to just the outer wall covering, but today a reference to rainscreens includes the entire system: the outer façade and the components behind it.

In addition to moisture prevention, rainscreen systems also serve to manage or control exposure to

  • ultraviolet radiation

  • negative wind pressures

  • heat transfer into and out of the building

  • air infiltration

  • vapor transmission

As the design and construction industries have become increasingly focused on versatility and sustainability, the distinct advantages of rainscreen cladding technology have resulted in a steady rise in popularity across both commercial and residential projects worldwide.

How Does a Rainscreen Façade Work?

Multiple components or layers work together in a rainscreen façade, separating the outer cladding from a supporting wall to prevent moisture infiltration.

Supporting Wall

The supporting wall may be constructed of concrete, brick, wood, or another durable material. It carries the weight of the cladding while ensuring the stability of the building.

Weather Resistant and Thermal Layers

A thermal layer along with air and moisture barriers are installed on the outside of the supporting wall. The type and thickness of the rainscreen insulation layer is determined by the project details and the material’s insulating capacity.

Ventilation/Drainage Cavity

The open air cavity is the hallmark feature of the rainscreen façade system. Open on the top and bottom, this cavity promotes water drainage, and the constant circulation of air allows water vapor to escape and evaporate.

Cladding Substructure

Depending on the exterior façade material to be used, architects have several options for substructure materials, including wood, steel (with galvanized coating), and aluminum. This substructure is what allows space for the open air cavity behind the exterior façade cladding.

Exterior Cladding

Exterior cladding panels are affixed to the substructure, completing the rainscreen façade system. Choosing a durable, high-quality cladding material is critical to ensure an effective and efficient rainscreen façade. Numerous cladding materials are available including wood and metal, but phenolic panels (also called high-pressure laminate or HPL panels) stand out for their durability, low maintenance, and aesthetic appeal.

Fastening Options for Rainscreen Façades

Rainscreen façades must meet the needs of each distinctive building and project; that means different projects will benefit from different fastening systems.

Exposed fastening system with Fundermax panels

Exposed Fastener System

By utilizing Max Compact Exterior HPL façade panels and color-matched screws or rivets, an exposed fastener system can offer maximum design freedom at an economical price point.



Concealed fastening system with Fundermax panels

Concealed Fastener System

By utilizing embedded anchors on the back side, HPL façade panels can hang on horizontal rails attached to vertical wall brackets, offering maximum design flexibility without exposing fastener points.


Modulo Plank System

Modulo is a type of concealed fastener, closed joint, modern façade plank system. Utilizing a concealed clip system, the panels can be installed without any open joints vertically or horizontally.


Scaleo Lap Siding System

Another type of concealed fastener system, Scaleo is an attractive lap siding system that offers an ideal combination of ease of installation with the proven benefits of the prefabricated Max Compact Exterior HPL façade panels.


What Are The Benefits of Rainscreen Cladding?

1. Ease of Installation

Lightweight panels and multiple fastening options make rainscreen cladding simple and easy to install.

2. Sustainability

Rainscreen cladding helps to minimize carbon dioxide emissions by reducing the demand on a building’s heating and cooling systems.

3. Maintenance

Required maintenance of rainscreen cladding is essentially zero, especially if you opt for a product like Fundermax rainscreen cladding panels which are graffiti-, impact-, and scratch-resistant.

4. Sound-Proofing

Rainscreen insulation provides not only thermal insulation but also acoustic. Significantly reducing noise pollution is an often overlooked but significant benefit of a rainscreen façade. Some insulation provides more sound-proofing than others and Rockwool mineral wool does a great job at providing energy-efficient, sound-proofing rainscreen insulation in colder climates.

5. Aesthetics

Utilizing HPL compact panels in rainscreen systems offers countless options, including colors, textures, and fastener systems. This means unmatched freedom for your exterior design.

6. Cost-Effectiveness

Rainscreen façades built with HPL panels maximize building heat retention and absorb the sun’s heat, reducing your heating and cooling costs. Low-to-no maintenance means the cost of upkeep is minimal.
