What is a rainscreen?

Terra Cotta Rainscreen Assembly: Panels Installed
Terra Cotta Rainscreen Assembly: Support Framing Installed

A Terreal Terra Cotta rainscreen consists of an outer panel, a ventilated cavity and an inner skin. A rainscreen system is pressure equalized – the joints are open allowing pressure equalization in driving rain conditions to be instantaneous. Pressure inside the cavity is equal to pressure outside, thus precipitation has no inclination to be driven into cavity. Majority of the water is deflected off the outside face – any penetrating water is disposed of through drainage.


How Rainscreen works


Typical Terra Cotta Wall Assembly Section


The Terra Cotta Rainscreen advantage

  • Improves upon failure in conventional sealed systems.
  • Protects the wall system from direct rain, wind, and weather due to an additional skin.
  • Prevents water penetration in the wall due to better ventilation.
  • Less pressure/ wind let in on the primary wall – acting as a shied.
  • Equalized pressure leads to lower water absortion.
  • Thermal benefits lead to energy savings.
  • Air space reduces heat bridge, therefore less heat transfer/ lower cooling costs.
  • Added airspace helps prevent condensation.
  • Better comfort inside the building, heated thoroughly in winter and cool freshness in the summer.
  • Terra cotta panels are high impact resistant (double skin products have highest Q4 rating in France for impact) panels do not easily break.
  • Broken tiles can easily be replaced without removing system.
  • Terra cotta panels are color permanent and do not fade, no painting required.
  • By concealing critical building joints from UV rays and weather elements, much less re-pointing and re-caulking required – which equals cost savings.
  • Simple system that can be installed by many different trades.
  • Can be installed year-round in all weather conditions due to no use of mortar.
  • Some systems are lightweight and can  be installed from man-lifts preventing the need of scaffolding – money saving.
  • Lightweight clay panels can be installed much quicker than traditional heavy systems such as brick/mortar, stone, granite, and marble.
  • Extra protection of façade and structure.
  • Traditional building cladding leaks because of many exposed joints with greater pressure on the exterior façade forcing water into the structure.
  • Helps avoid thermal shock which results in less cracking in the structure.
  • Maintenance-free building system – no re-caulking.
  • Eliminates and decreases many of the joints found in traditional cladding methods reducing potential leaks.
  • Less water passage, less cracking, pressure equalization, and constant ventilation = Water Tight Structure.
