## [faq] FAQ CovaTherm
- [faq-product-name] CovaTherm
- [faq-1-q] What is the difference between CovaTherm 8 and CovaTherm 20?
- [faq-1-a] Both share the same two-component polyurethane resin formula. CovaTherm 20 adds an exclusive Covalba anti-UV top coat finish. This top coat protects the reflective pigment from UV degradation and maintains the SRI 118 for 20 years (4,000-hour QUV test). CovaTherm 8 is ideal for a tighter budget, while CovaTherm 20 costs less over 20 years because it does not require reapplication.
- [faq-2-q] Does a cool roof coating increase heating consumption in winter?
- [faq-2-a] This is the most frequently asked question, and the answer is no. In winter, the sun is low and weak: it heats vertical facades far more than the horizontal roof. The loss of solar gain on the roof is therefore minimal, limited to a few hours per day during the shoulder seasons (fall and spring), and far outweighed by the thermal gain accumulated during the warm months. Over a full annual assessment, a cool roof coating reduces the building's energy bill in the vast majority of cases.
- [faq-3-q] What is the Solar Reflectance Index (SRI)?
- [faq-3-a] The SRI represents a roof's ability to reject solar heat, calculated according to the ASTM E1980 standard. Hot materials have an SRI close to 0, while cool materials exceed 100. CovaTherm reaches an SRI of 119 when new and 118 when aged, among the best-performing on the market. Most competitors report only the new SRI, which drops quickly.
- [faq-4-q] What is the difference between a cool roof coating and standard white paint?
- [faq-4-a] Standard white paint reflects visible radiation but absorbs infrared, which sharply limits its cooling effect. Its thermal performance also collapses within a few years. A cool roof coating, by contrast, combines high solar reflectance (above 0.85) and high thermal emissivity (above 0.90) to achieve a high SRI, certified to the ASTM E1980 standard. Its specific pigments and resins prevent chalking and maintain reflectivity over time.
- [faq-5-q] Is my building compatible with CovaTherm?
- [faq-5-a] CovaTherm is compatible with the vast majority of industrial and commercial roofs: bituminous membrane, concrete, EPDM, fiber cement, PVC, and slate. If your roof has cracks or leaks, consider CovaSeal 20. For steel deck roofs, CovaMetal 20 is the right product. A technical assessment determines the best solution.
- [faq-6-q] Is a cool roof coating waterproof?
- [faq-6-a] CovaTherm is a cool roof coating, not a waterproofing system. For a roof with microcracks or leaks, CovaSeal 20, our waterproof cool roof coating, takes over by combining the cool roof effect and liquid waterproofing in a single application. A technical assessment helps determine the solution best suited to the actual condition of your roof.
- [faq-7-q] Does the application disrupt my operations?
- [faq-7-a] No. Everything is done from the outside. The machines stay at the base of the building, with only hoses running up to the roof. No interior access, no noise, no dust. Zero impact on your HACCP or GMP certifications. Application typically takes 2 to 5 days, depending on the roof area.
- [faq-8-q] Can a cool roof coating be applied DIY?
- [faq-8-a] Consumer-grade cool roof paints are sold for DIY use, but the quality of the application directly determines the coating's performance and lifespan. An incorrectly dosed primer, a coat that is too thin, or application in damp weather can cut reflectivity by 30 to 50% within a few months. It is also a safety matter: working on a roof requires PPE, training, and suitable equipment. Covalba recommends entrusting the work to a professional applicator trained on its products. This is a condition of the manufacturer warranty.
- [faq-9-q] What does a cool roof coating cost per m²?
- [faq-9-a] CovaTherm 8 and CovaTherm 20 are priced as coating supply, per m² of material, with the exact rate depending on your market and the volume ordered. Installed pricing also depends on substrate condition, surface preparation, and your contractor's labor rates. Request a detailed quote for your project.
- [faq-10-q] How much cool roof coating is needed for 1,000 m²?
- [faq-10-a] Allow between 0.5 and 0.7 liters per square meter for the complete system, meaning primer, base coat, and top coat combined. For a 1,000 m² surface, the total volume is therefore between 500 and 700 liters. The Covalba quote always includes precisely sized material quantities, based on the condition of the substrate and the actual coverage rate on your type of roof.
- [faq-11-q] What savings can I expect?
- [faq-11-a] Our clients report a -8°C to -13°C indoor temperature drop during heat peaks, and a 15% to 40% reduction in their air conditioning bill. On a 5,000 m² roof, this typically represents substantial annual savings (figures vary by market and energy prices). The average payback period is 14 months.
- [faq-12-q] What maintenance does a cool roof coating require?
- [faq-12-a] The CovaTherm top coat has self-cleaning properties. We recommend an annual inspection and a water rinse to clear away particles and optimize solar reflection. No chemical products are needed.
- [faq-13-q] What are the warranties?
- [faq-13-a] Covalba provides a coating warranty covering the product's reflective performance, conditional on correct application per the datasheet. Accelerated aging test (4,000-hour QUV): reflective performance maintained. With the top coat: reflectivity maintained for up to 20 years. Annual inspection recommended.
- [faq-14-q] Does CovaTherm improve waterproofing?
- [faq-14-a] CovaTherm is not a dedicated waterproofing solution, but its thick, elastic coating fills microcracks up to 2 mm and forms a continuous film that contributes to improved waterproofing. For significant waterproofing problems, CovaSeal 20 is the appropriate solution.
- [faq-15-q] Is CovaTherm compatible with my solar panels?
- [faq-15-a] Yes, and it is actually beneficial. Photovoltaic panels lose 0.4% of efficiency for every additional degree. By cooling the roof, CovaTherm improves their output by 3 to 7%.
