Known for its reliability, adaptability, and efficiency, Trocal roofing offers a combination of performance and design that meets various architectural needs. This comprehensive guide will help you understand what Trocal roofing is, its benefits, installation process, maintenance requirements, and how it compares with other roofing systems.What is Trocal Roofing? Trocal roofing refers to roofing membranes made from polyvinyl chloride (PVC), originally developed by the company Trocal in Germany in the 1960s. These single-ply membranes are designed specifically for flat or low-pitch roofs, providing a durable, weather-resistant, and flexible solution for waterproofing. Over the years, Trocal products have become synonymous with quality flat roofing solutions in both commercial and domestic settings.Main Features and Advantages 1. Durability: Trocal membranes are highly resistant to UV, chemicals, and environmental stress, ensuring a long service life. 2. Lightweight: These roofs do not add excessive load to building structures. 3. Flexible Installation: Suitable for new builds or refurbishments, Trocal roofs can be laid over different substrates. 4. Low Maintenance: Once installed, Trocal roofs require minimal upkeep, making them cost-effective over the long term. 5. Watertightness: Heat-welded seams create a continuous, watertight surface.Installation Process The installation of a Trocal roof typically involves cleaning the roof deck, laying the membrane, and bonding or mechanically fixing it to the substrate. Seams are welded using hot air equipment, creating strong, watertight joins. Each installation should be done by trained professionals to ensure longevity and performance.Maintenance & Longevity Regular inspections, especially after extreme weather, are essential to spot potential vulnerabilities. However, due to its robust manufacturing, Trocal roofing often requires less maintenance than other roofing materials. When taken care of, these roofs can last up to 30 years or more.Comparing Trocal to Other Roofing Systems Compared to traditional felt or bitumen roofs, Trocal offers a lighter, more flexible, and longer-lasting alternative. While EPDM (rubber) and TPO (thermoplastic polyolefin) are also popular, Trocal’s proven track record and specific product formulations provide some of the best weather and UV resistance available.As a designer, one of the aspects I appreciate about Trocal is how it enables seamless integration into modernist and minimalist architecture. The clean lines and consistent finishes complement innovative building shapes and interior spatial arrangements. During the planning phase, using a 3D floor planner can help you visualize how roof options like Trocal will interface with your building’s overall aesthetic and layout, ensuring functional and harmonious results.Tips 1:When considering Trocal roofing, always consult with an experienced installer and factor in your local climate conditions. Proper planning and regular inspections ensure that your investment remains protected for decades.FAQQ: What is Trocal roofing made of?A: Trocal roofing membranes are manufactured from high-quality PVC (polyvinyl chloride), designed specifically for waterproofing flat or low-pitch roofs.Q: How long does Trocal roofing typically last?A: With proper installation and maintenance, Trocal roofing can last upwards of 30 years.Q: Is Trocal roofing suitable for residential homes?A: Absolutely.
