What is Drylast Cool Roofing Technology?
Drylast Cool Roofing is an innovative high-performance roofing solution designed to boost energy efficiency and reduce environmental impact. At its core is DRYLAST CRWR®, a high reflectance white coating that reflects sunlight and lowers roof surface temperatures. This means buildings stay cooler naturally, cutting down on air conditioning use and shrinking the carbon footprint. The technology is versatile, adhering to a wide range of substrates like concrete, bitumen, polyurethane, EPDM, steel, aluminum, and PVC—no need for costly roof removals or replacements. Perfect for industrial and commercial roofs, Drylast’s cool roofing offers a smart, passive way to keep spaces comfortable and energy bills in check.
Main Benefits of Drylast Cool Roofing
Drylast’s CRWR® technology packs a punch when it comes to performance. Here are some key figures and facts that highlight its impact:
- 88% Reflectance — meaning most sunlight bounces right off
- 0.9 Emissivity — excellent heat radiation properties
- 500% Elongation — super flexible to withstand roof movements
- BROOF (T1) to (T4) Fire Classification — safety covered
- 111 Solar Reflectance Index (SRI) — top-tier solar reflectance
- 95% Dry Extract — high solid content for durability
- Less than 1 KG/M2 — lightweight coating that won’t weigh down roofs
- Up to 50% reduction in surface temperature
- Up to 30% savings on air conditioning bills
- Indoor temperature drops by up to 10°C during summer
How Does Drylast Cool Roofing Work?
Imagine a roof without Drylast — it soaks up heat like a sponge, making the building underneath hotter and forcing air conditioners to work overtime. Now, add Drylast CRWR® to the mix, and the story changes. The coating reflects sun rays back into the atmosphere, keeping the roof surface cool and the building’s interior comfortably cooler. This passive cooling effect slashes energy consumption and helps buildings breathe easier during scorching days. It’s a simple principle with powerful results.
Advantages Beyond Energy Savings
Drylast’s cool roofing isn’t just about cutting energy bills. It also enhances thermal comfort, making indoor spaces more pleasant by reducing heat buildup. Plus, it extends the lifespan of air conditioning systems by easing their workload. Environmentally, it fights urban heat islands (UHI), those pesky hotspots in cities caused by heat-absorbing surfaces. By reflecting sunlight and lowering temperatures, Drylast helps reduce the carbon footprint of buildings. And if solar panels are part of the roof, no worries — this technology plays nicely with photovoltaics, boosting overall energy efficiency.
Durability and Compatibility
One of Drylast’s standout features is its liquid solution, which can be applied easily by roller or airless spray. It’s tough against temperature swings, hydrolysis, and UV rays, meaning roofs stay protected and last longer. The coating’s flexibility (500% elongation!) allows it to handle roof movements without cracking. Plus, it sticks well to many substrates — concrete, bitumen, polyurethane, EPDM, steel, aluminum, and PVC — making it a versatile choice for various roofing needs. This adaptability saves time and money by avoiding the hassle of removing old roofing materials.
