6 Reasons Why Architects are Choosing Ecoste WPC for Creating Everlasting Rainscreens

Architects have a wide range of options but they choose WPC as their most superior choice of materials that can serve as a frame of a rainscreen construction while also adding to an aesthetically stunning structure envelope!

Many types of cover or cladding materials can be an element of an efficient rainscreen method. But architects must contemplate distinct determinants when defining this material, including the desired aesthetics, fire resistance, sustainability, installation demands, lifetime preservation, and project reserves.

Lately, the materials prepared for rainscreens were aluminum panels, phenolic panels, or fiber cement panels. But the availability of extruded material like wood polymer composite is changing the game! As it is being appropriate for both rainscreen applications and other exterior applications, extruded composites are thin, light, durable, and noncombustible.

Let’s have a close look at Rainscreens and its Application!

Rainscreen systems present a shield upon rain, snow, and ice, blocking conceivably damaging moisture from bleeding through the surface of the walls of the building. 

Rainscreen systems can assist in protecting a structure from wind, rain, and all forms of intense weather conditions. As part of a water mitigation system, rainscreens are the first and foremost necessity to repel water. Nevertheless, they also necessitate being durable enough to resist other environmental forces such as wind, UV transmission, and excessive heat and cold.

A rainscreen is an exterior wall feature in which the exterior cladding or siding is fixed with tiny air gaps between the cladding and the rest of the wall molding. This space serves to build a capillary tear and renders a path for moisture to exit the building envelope. This approach not only intensifies the durability and persistence of the structure but also offers to the vitality and well-being of occupants.

If you go for WPC cladding solutions(Ecoste 2D & 3D panels), the main benefit is that it promotes drying! It also accommodates cladding that has become wet from the precipitation dry out process. The long-term advantages of moisture management include a better, durable, and hygienic building. To understand bonuses, let’s take a look at the ways moisture can intrude upon the building envelope.

The purpose of a rainscreen is not just to restrict moisture from penetrating the building shell but also to give an internal midpoint of water drainage and dehydration if water gets through the structure. A good rainscreen will accomplish the “4 Ds”: deflecting water, draining moisture, drying any water that has seeped the cladding, and be efficiently durable to endure the components over time without worsening.

Let’s take a peep through this blog to know how the usually applied materials stack up when it comes to the significant problems of a design and its performance.

Water mitigation

Wood-plastic composite, fiber cement, cast-in-place concrete, and extruded concrete are all highly moisture-resistant materials. The main issue with cement boards is the cellulose wood fiber, which can wick water into the core and cause failure; this is also a fire issue. Because extruded concrete uses glass fiber, it does not absorb water and does not burn. But if chosen WPC, then you will get a highly waterproof cladding solution!

Fire resistance

Some manufacturers include fire retardants in their WPC products; however, these chemicals raise concerns about health and environmental impacts. All of the concrete-based products are either non-combustible or fire-resistant and can be part of fire-resistant assemblies. One of the downsides of wood-plastic composite products is that they are not fire-resistant unless they are a quality WPC. 


Material weight is an important factor as it impacts time, labor and costs. Different panel dimensions and thicknesses may be suitable for various projects.
Cast-in-place concrete opposes the other materials as it is delivered in a ready-mix form and poured on-site. However, the cured product is heavy, but as WPC is a polymer-based material its weight is 10 x light and also eliminates extended timelines, workmen efforts, and high budget stories.


As with any exterior cladding, the material practiced in rainscreen must be able to withstand high winds, wind-driven rain and hail, and even wind-borne debris impacts. The material should be powerful to face temperature variations without losing its strength.

Concrete-based materials are very strong; however, cast-in-place concrete can corrupt if the inner reinforcing bar comes in contact with water and starts to rust. Concrete can thereby develop stress cracks when set under heavy weights or could wither away due to external climatic conditions. Here WPC has an advantage! The WPC cladding composition & high density gives extruded panels a remarkably high strength-to-weight ratio through which it does not crack, bend, or withers away by the time!


Exterior cladding is unveiled continually to the details, yet it must perform for the life-length of the building. Wood-plastic composite and all of the concrete-based products score high in durability if compared to wood; however, as stated above, rust can compromise the quality and harm the strength of the cladding!

Design Versatility and Aesthetics

Exterior cladding advances exponentially to a structure’s aesthetic. Consequently, rainscreen materials should ideally fulfill their roles but also hold a variety of alternatives when it comes to tone, pattern, and surface smoothness. Furthermore, fiber cement can be produced with wood grain but also comes in a smooth finish, depending on the desired aesthetic. The material comes in panels or planks, accommodating a range of architectural styles. 

Made of mineral-based raw materials, extruded concrete has an organic aesthetic that is compatible with many architectural styles but lacks its aesthetic properties in the long run.

Many standard and custom colors and various surface treatments are possible, all of which influence its character. But the most convenient types of material to be used are WPC wall panels that can likewise mimic wood and can be painted in desired colors without any imperative maintenance costs!

Therefore, Ecoste Cladding Solutions can widely be used for Rainscreening without creating any long-term hassle! Connect with our experts today and let your structures taste a never denying lifetime guarantee!
