Facade Heat Saving Coatings

Exterior wall coating that is waterproof, self-cleaning, and breathable.

This technologically advanced, two-coat, waterproof exterior wall coating reduces water absorption by 96% on mineral building materials. On completion Pinnacle Wall & Roof Coating Systems will supply a 15 year company guarantee and a 10 year manufacturers’ guarantee.

Stay Dry & Warm

Known as the ‘lotus effect’, the exterior wall coating creates a waterproof, ultra-hydrophobic surface because it is similar to the water-repellent properties of a lotus leaf. As rain falls, coated mineral surfaces repel the water, causing it to form beads (since the water is attracted to itself more than the surface) and run off without being absorbed. It has been tested independently and has been found to reduce water absorption by 93.4%, thus meeting the requirements of British Standard BS EN ISO 7783:2011.

Testing conducted by UKAS certified laboratories demonstrated that the wall coating reduces water absorption of the walls and contributes to improved thermal performance. It has been demonstrated to meet the EAD 040083-00-0404 standards.

Testing in a hygrothermal chamber revealed that a wall treated with the wall coating and subjected to repeated heat-rain conditions in accordance with EAD 090062-00-0404 reduced heat loss compared with the uncoated (control) wall. In comparison to ProPERLA-coated walls, uncoated walls lost 60C more heat on average.

As well as improving thermal efficiency, the wall coating contributes to lower energy consumption and lower energy bills by keeping walls dry. Walls that are damp act as ‘thermal bridges’, allowing heat to transfer twice as fast from the inside out.


Importantly, ProPERLA Facade Coating is highly breathable. The coating had little effect on substrate water vapour diffusion when tested in accordance with BS EN ISO 7783:2011.

The ProPERLA Exterior Facade Coating keeps walls and cavities dry while allowing air and moisture to escape. As a result, the building envelope maintains its ability to breathe. As opposed to some stone and brick sealing products, it does not coat the pores with a thin film that blocks them.

Prevent & Protect

Not only do our exterior wall coatings improve the exterior appearance of your building, but they also help maintain and protect it long term.

  • The surface mimics the lotus leaf by self-cleaning. Rainwater will simply wash away dirt particles from ProPERLA treated surfaces.
  • A dry surface created by the wall coating deters the growth of moss, algae, and lichens.
  • Protects against discolouration.
  • In addition, it prevents the building’s surface from deteriorating or breaking down due to the damaging effects of the environment, including wind-driven rain, frost, high humidity and sea salt.
  • Sunlight does not affect the performance of this product.
  • Colour stability ensures a long-lasting, attractive finish.

25 Year Proven Performance

The ProPERLA Facade Coating has been independently tested by UKAS-certified body Lucideon and has been found to meet the following standards;

  • EAD 090062-00-0404 – 25 year hygrothermal performance.
  • EAD 040083-00-0404 – external thermal insulation composite.
  • BS EN ISO 7783 – 2011 – water vapour diffusion.
  • BS EN ISO 12572 – water vapour resistance.
