Water cannot stick to the coated surface but forms droplets that run off the surface.
Water and moisture are able to escape the masonry due to the high breathability rating of the products.
Masonry remains clean and attractive as dirt is unable to take hold.
Reduces water absorption by more than 93%. Dry walls mean less heat loss.
We specialise in protecting and insulating homes using advanced proPERLA® coating systems — trusted across Europe for their exceptional weatherproofing performance and energy-saving benefits.
Our core service focuses on roof insulation and protection, helping to keep properties dry, breathable, and thermally efficient throughout the year. In addition, we apply proPERLA® treatments to walls, brickwork, masonry, and other external surfaces to prevent damp penetration, reduce heat loss, and significantly cut ongoing maintenance requirements.
For homeowners seeking a cleaner, warmer, and more energy-efficient property with long-lasting protection from the elements, we offer professional installation using manufacturer-approved proPERLA® products for reliable, lasting results.
Reduce energy costs and protect homes with our range of super hydrophobic coatings suitable for a range of surfaces. All come with a manufacturers guarantee for peace of mind.
We know choosing an external wall insulation system is a big decision, and it’s completely normal to have questions before moving forward. Properla is a specialist masonry-cream insulation solution, designed to improve the thermal performance of solid walls while protecting your home from driving rain and damp.
Below you’ll find answers to the most common questions we receive about how Properla works, what benefits it offers, and whether it’s the right option for your property. If you can’t find the information you’re looking for, our team is always happy to provide clear, honest advice tailored to your home.
Properla is a high-performance coating designed to provide thermal insulation, protect surfaces, and improve energy efficiency. It can be applied to walls, roofs, industrial equipment, HVAC systems, and more.
Our coatings form a protective layer that reflects heat, prevents heat loss, and protects surfaces from moisture, corrosion, and wear. This helps maintain temperature control and reduce energy costs.
Yes. Properla coatings are formulated with low VOCs and sustainable materials to minimize environmental impact while providing top-tier insulation performance.
Absolutely. By improving thermal insulation and reducing heat transfer, Properla coatings help maintain optimal temperatures, which can significantly lower heating and cooling costs.
Yes. Properla coatings are designed to perform in a wide range of climates, offering heat reflection in hot areas and insulation in colder environments.
Moisture in building materials is a key driver to energy loss. Wet materials transfer heat much quicker than dry materials. Tests have shown that a damp content of 5% in a plain brick wall can lower the insulation performance by up to 50%. By keeping walls and roofs dry, ProPERLA coatings help to improve thermal efficiency.
Our proPERLA® hydrophobic coating restores and protects exterior surfaces while improving thermal performance and water resistance. The result is a cleaner, brighter finish paired with lasting protection against moisture, algae, and weather damage.
This treatment not only enhances your home’s appearance but also helps reduce heat loss, prevent damp penetration, and minimise ongoing maintenance — delivering both visual and practical benefits that last for years.
ProPERLA wall & roof coatings have been rigorously tested and certified by the UKAS accredited testing laboratory, Lucideon (No. 0013), to give you peace of mind.
Lucideon is an independent materials testing and analysis laboratory. Using their state-of-the-art facilities and scientific expertise, Lucideon can thoroughly test product performance and provide impartial results.
ProPERLA coatings have been tested for durability, thermal insulating properties, breathability and water repellency.
ProPERLA Facade Coating is officially certified by the British Board of Agrément (BBA), an independent, UKAS-accredited authority recognised across the construction and civil engineering sectors.
