Tremco Construction Products Group (“Tremco CPG”) today announced that the acquisition of Kalzip GmbH (“Kalzip”) was finalised following completion of the standard regulatory review process. A global leader in the design and production of aluminium-based roofs and facades for building envelopes, Kalzip now is part of Tremco CPG.

Founded in 1968, Kalzip specialises in lightweight, weather-resistant and flexible roof systems, along with aesthetically advanced and highly functional façade technologies. Key projects include the Estadio Santiago in Madrid, the Skyway Mont Blanc in Italy and the Pickering Go Pedestrian Bridge in Canada. By combining Kalzip’s innovative aluminium solutions with the broader portfolio of Tremco CPG UK, and wider Europe – which includes roofing systems, joint sealing, bonding and insulation, passive fire protection, floor coatings and concrete protection and repair – the partnership supports Tremco CPG’s strategy of delivering a seamless, fully integrated approach to modern construction.

This comprehensive offering enhances efficiency, durability and aesthetic performance across both new-build and refurbishment projects, enabling clients to benefit from coordinated systems designed to work together throughout the entire building lifecycle. As an integral part of Tremco CPG’s holistic offering, their high-quality, customisable solutions will continue to be sold under the Kalzip brand name in Europe and most major markets around the world, thanks to their strong global market position. In North America, the Kalzip line will be integrated into Tremco’s well-established brands.

“In addition to expanding the Tremco CPG business across Europe, India and other regions around the world where Kalzip already has a strong presence, this acquisition will eventually allow us to market a wider range of aluminium building envelope options to our North American customer base,” said Scottie Stinson, president of Tremco CPG Inc. “This is critical as demand grows for aluminium building systems due to their many benefits including durability, longevity, sustainability and energy efficiency.”

“Our global reach, complementary product portfolios and customisable solutions will enable Tremco and Kalzip to deliver tailored, high-performance, end-to-end building envelope systems for varied architectural and restoration needs across diverse markets and large-scale projects,” Stinson said. “And our shared commitment to green building practices will continue to drive innovation in sustainable construction worldwide.”

RoofersCoffeeShop.uk was honored to be on site in Liverpool celebrating the best of the U.K. liquid roofing industry. 

The energy in Liverpool was undeniable as the Liquid Roofing and Waterproofing Association (LRWA) hosted its sold-out 2026 awards gala, bringing together more than 430 roofing professionals for a night dedicated to craftsmanship, innovation and community. RoofersCoffeeShop.uk was proud to be there, sharing in the excitement and recognizing the outstanding work shaping the future of liquid roofing and waterproofing. 

From the moment the evening began, it was clear that this event continues to grow in both prestige and impact. Now in its eighth year, the LRWA Awards have become one of the most anticipated events in the U.K. roofing calendar, highlighting the very best across projects, people and performance. 

Recognizing the people behind the projects 

The Student of the Year award went to Harry Robinson of Blackpool Industrial Roofing, whose dedication, professionalism and passion for the trade set him apart. Completing his NVQ ahead of schedule and showing up every day ready to learn, Harry represents the future of the industry. 

Trainer of the Year was awarded to Shane Copestake of Triflex, recognized for his engaging training style and commitment to developing skilled applicators through clear communication and hands-on learning. 

And in a moment that truly resonated across the room, Ray McCarten received the Special Contribution Award. With more than four decades in the industry, his work in training and workforce development has helped shape today’s skilled workforce and elevate standards across the sector. 

Showcasing standout projects across the U.K. 

What stood out most this year was the level of excellence across every category, especially in the Liquid Waterproofing Project of the Year where StructureCare, a Tremco company, earned top honors for their work on the Bell Street Green Transport Hub in Dundee. This project demonstrated how liquid-applied roofing and waterproofing systems can extend the life of aging structures while supporting modern performance expectations. The StructureCare team addressed extensive deterioration within the existing multi-level structure through comprehensive deck refurbishment, targeted concrete repairs and the installation of corrosion mitigation systems designed to protect the building long term. 

The liquid-applied system allowed the team to navigate complex detailing and maintain continuity across the structure, all while keeping disruption to a minimum. In addition to the technical achievement, the project delivered strong sustainability outcomes through responsible material management and by repurposing an existing structure into a revitalized transportation hub that better serves the surrounding community. 

Overall, the project awards demonstrated just how far liquid roofing systems have come, especially when it comes to solving complex challenges. Additional awards included: 

• Murray Edwards College, Cambridge, took top honors for projects under 1,000 m², showcasing innovation on a uniquely designed historic roof where traditional approaches were limited  
• Christ’s College, Cambridge, won for projects over 1,000 m², successfully blending preservation with modern performance requirements  
• One Leadenhall in London stood out in the buried application category, overcoming the logistical challenges of a dense urban environment  
• 76 Southbank, London, earned Sustainability Project of the Year, highlighting environmental responsibility and community impact  

All of the projects highlighted not just technical excellence but also the growing role of sustainability, innovation and collaboration in roofing today. 

Sustainability and innovation take center stage 

One of the most exciting aspects of this year’s awards was the continued focus on sustainability. Now in its second year, the Sustainability Project of the Year category evaluated entries on environmental impact, social value, innovation and responsible supply chain practices. 

Projects like 76 Southbank showed how roofing is playing a critical role in achieving broader environmental goals, from biodiversity gains to reduced carbon impact and long-term building performance. 

This aligns with what we are seeing globally. Roofing is no longer just about protection. It is about performance, energy efficiency and long-term environmental responsibility. 

A night that reflects a growing industry 

As LRWA leadership shared throughout the evening, the continued growth of the awards reflects the strength and momentum of the liquid roofing sector, with innovation and quality continuing to raise the bar. 

From our perspective at RoofersCoffeeShop.uk, this event reinforced something we see across the entire roofing industry. When contractors, manufacturers and associations come together to share knowledge and celebrate success, it drives the entire industry forward. 

Looking ahead 

The LRWA Awards 2026 were more than just a celebration. They were a powerful reminder of the talent, dedication and innovation happening across the U.K. roofing market. 

RoofersCoffeeShop.uk is honored to help share these stories and connect the global roofing community. Congratulations to all the winners, those highly commended and everyone who continues to push the industry to new heights.

This new system advances the world of restoration coatings with less downtime and more value. 

The new AlphaGuard FC LO Roofing System, now available in the U.S. and Europe, is designed for refurbishment by minimising challenges faced on jobs. This roofing system represents a significant advancement in restoration coatings. If you're a contractor looking to increase job site efficiency, reduce delays and deliver exceptional results, extend your roofing system portfolio with AlphaGuard FC LO. 

Why AlphaGuard FC LO stands out 

1 - Low odour formula 

Traditional roofing systems often emit strong, lingering odours that can disrupt operations and make installations over occupied spaces challenging. The low-odour formula of AlphaGuard FC LO ensures minimal disruption by eliminating strong smells. This feature is particularly ideal for projects conducted over 24 hour operational facilities such as hospitals or domestic spaces. 

2 - Quick cure for faster results 

Time is money in the roofing industry, and delays can be costly. With AlphaGuard FC LO, contractors benefit from its quick-curing ability, with curing times as short as 30 minutes. This ensures faster project completion and reduces downtime for building owners, making it an optimal choice for fast restorations or projects requiring minimal disruption.

3 - Single-coat application 

Unlike other waterproofing systems on the market, AlphaGuard FC LO eliminates the need for attending site for a second topcoat. With its singular coat application, contractors save significant time, labour and costs. What’s more, the system reduces the necessity of extended cost of safety equipment such as scaffolding as it’s a minimum 30% faster to install as it mitigates delays between two coat systems from weather-related delays and availability of applicators.  

4 - High-solids formula for trusted durability 

AlphaGuard FC LO boasts a high-solids composition, ensuring that when installed correctly, the membrane maintains its intended thickness. This gives contractors the confidence to deliver a reliable and durable roof every time. 

5 - High reflectivity = energy savings 

AlphaGuard FC LO isn’t just great for roofing contractors; building owners benefit too. With its high-reflectivity design, this system helps reduce rooftop temperatures, resulting in lower energy costs by decreasing the workload on cooling and rooftop equipment. 

Add value for your clients with AlphaGuard FC LO

In today’s competitive roofing market, standing out means delivering fast, efficient and cost-effective solutions. The new AlphaGuard FC LO system helps you do just that, offering clients a smarter alternative to full roof replacement by preserving existing structures, minimising waste and extending roof life — all backed by up to a 25-year warranty.

AlphaGuard FC LO lets you deliver speed, quality and value — giving your clients more while helping you stay ahead.

Learn about how Tremco has established itself as a waterproofing and coating leader not only nationally, but internationally.

You’ve probably heard of Tremco Roofing, who has been delivering high quality, comprehensive roofing and weatherproofing solutions since 1928, but have you heard of Tremco Construction Products Group which operates on a global stage? In this episode of Roofing Road Trips®, Heidi J. Ellsworth spoke to Mardee Billingsley, the executive vice president of Tremco Construction Products Group about what they do and where they operate.  

Mardee has been working with Tremco for over 28 years now. She has worked in all parts of the company, from running a WTI service department to rooftop construction management, but in the past four or five years her focus has been on Tremco’s international expansion through the Construction Products Group (CPG. Mardee shared a bit of the background on this branch of Tremco, sharing, “Tremco Roofing is a division of Tremco Construction Products, which is our overall platform that provides sealants, waterproofing, roofing, concrete masonry products. And WTI would be the service division under that as well. Tremco Construction Products operates in North America as well as Europe. Then Tremco CPG is an operating group for RPM International, which is a $7 billion global company that specializes in specialty coating, sealants, building materials and related services in other continents.”  

This expansion has been a great opportunity for Tremco to continue to grow their expertise and innovate new weatherproofing solutions. On the administrative side, going global brings a fair number of cultural and linguistic challenges. Mardee explained, “It’s not always the roofing that's different, it's the cultures and the environments. So we meet with our regional teams weekly or monthly and it's really not about roofing. Of course languages are the biggest barrier. And then financial and regulatory distinctions are all things that play into it.”

And when it comes to the products, these new environments have fueled the team at Tremco CPG to innovate and problem-solve in new ways. Mardee gave an example, saying, “If you get into areas like South Africa where it's on the coast and it's very salt water heavy, you get that corrosion in the air. In that situation, a typical acrylic metal coating, it just won't endure. So those roofs require a much more corrosive resistant coating, which we are able to connect clients there to through one of our other RPM partners.”
