For centuries, felt roofing systems have been a trusted and cost-effective way to waterproof buildings. However, in today’s demanding environment with stricter performance standards and growing environmental concerns, felt systems are expected to work a little bit harder, writes Justin Pitman, sales director of Proteus Waterproofing.

The UK felt systems market is estimated to be worth between £300 million and £400 million in 2023, with an expected annual growth of 2-3%. However, while growth remains buoyant, traditional, built-up felt systems have offered varying levels of durability, but there is now a clear trend towards high-performance systems that deliver extended lifespans, superior sustainability and unmatched resilience compared to cheaper alternatives.

The most compelling argument for these systems lies in their independently tested lifespans, frequently exceeding 35 years. Unlike some traditional felts, which can prone to cracking and deterioration within a short timeframe, high-performance felts, like the Proteus’ Endura range with advanced bitumen formulations, offer significant long-term benefits.

Fewer repairs and replacements translate to substantial financial savings over the lifetime of the roof. This means that building owners can enjoy extended protection from leaks and weather damage, minimising disruptions and ensuring uninterrupted building operation.

A demonstrably longer lifespan also adds value to a property. This is particularly crucial in the UK’s unpredictable climate, which throws various challenges at roofing systems.

High-performance felts like Endura rise to these challenges with exceptional weather resistance. Their advanced formulations can withstand harsh sunlight, torrential rain and even freezing temperatures, maintaining their integrity and flexibility for decades. They also deliver superior waterproofing, preventing leaks and ensuring building protection – a key reason why felt systems remain so popular.

Adaptability to modern architecture

They have been developed in response to more modern architectural demands, which are pushing boundaries with more daring designs and complex shapes. High-performance felt systems like Endura demonstrate their adaptability to meet these demands. Available in various thicknesses and configurations, the system can be installed on flat, pitched, or even curved roofs. Self-adhesive options and innovative cold-applied solutions further enhance efficiency and minimise project disruptions during installation.

So, while it might be considered a more traditional waterproofing material, we can see that felt continues to innovate. The growing demand for green roofs, for example, presents opportunities for felt systems that have been specifically designed for use with vegetated applications. Additionally, integrating felt system specifications and performance data into BIM models for improved building design and management is becoming increasingly common.

All systems in the Proteus Endura range are BBA certified to guarantee a service life of at least 35 years. The range includes a revolutionary addition – Proteus Pro-Felt® Endura AIRdhesive, a cold-applied alternative to conventional polymer-based single-ply membranes.

This single-layer bituminous membrane, saturated and coated with a high percentage of SBS modified bitumen, delivers the proven performance of an advanced elastomeric felt.

A high-quality polyester reinforcement ensures maximum strength and reliability. A mineral coating also provides an attractive and robust layer of protection on the upper surface, while the underside features a strong fleece finish for added quality and strength.

The Proteus Pro-Felt® Endura AIRdhesive system further offers the flexibility to choose a preferred installation method. It can be bonded using Proteus Pro-Membrane Adhesive or mechanically fixed to any suitable substrate. Additionally, it can be torch-applied for fast-track overlaying of existing roofs, saving time and costs.

Choosing a completely flame-free waterproofing solution, more often preferred by building owners, ensures safety and efficiency during installation, making it a true cutting-edge single-ply alternative for roofing professionals.

All Endura membranes are engineered to withstand the harshest conditions, including foot traffic, high temperatures, and wind uplift. They are built to last, ensuring peace of mind for building owners and minimal maintenance needs for contractors.

In short, high-performance felt systems like Proteus’ Endura range represent a significant leap forward in flat roofing technology. They offer a compelling combination of benefits for building owners, architects and roofing contractors.

It means that by choosing high-performance felt systems like Proteus Endura, roofing contractors can deliver exceptional value for their clients and contribute to a more sustainable future in the roofing industry.
