Our Flex Membrane Product Range

We offer two primary Flex Membrane products to cater to varying project requirements:​

TPO Plus Roof Membranes

TPO Plus Roof Membranes are a significant component of the Flex Membranes category. These membranes are available in various sizes and are renowned for their flexibility and strength, making them suitable for a wide range of roofing applications. They are especially practical for commercial buildings where robust and long-lasting roofing solutions are essential.

TPO Plus Self-Adhered Roof Membranes

Another pivotal product within this category is the TPO Plus Self-Adhered Roof Membranes. These membranes are equipped with self-adhering technology, eliminating the need for additional adhesives and making the installation process more straightforward and efficient. Ideal for those seeking hassle-free installation, these membranes maintain the same level of durability and reliability as the TPO Plus Roof Membranes.

Advantages of Single Ply Roofing Membranes

Single ply roofing membranes, such as those offered by Flex, have become a popular choice for flat and low-slope roofs due to their outstanding performance and versatility. Here are the main benefits:

1. Lightweight & Easy to Install

Single ply systems are significantly lighter than traditional roofing systems, making them easier and faster to install. This reduces labor time and associated costs, especially on larger commercial projects.

2. Highly Flexible & Adaptable

Whether you're working with complex roof shapes, detailing, or uneven surfaces, single ply membranes conform easily, ensuring a secure and watertight finish across the entire surface, with high flexible quality. 

3. Excellent Weather & UV Resistance

Flex single ply membranes are engineered to withstand harsh weather conditions, including heavy rain, snow, and prolonged sun exposure. They resist UV degradation and maintain their performance over time.

4. Long-Lasting Durability

With proper installation, single ply membranes can last 20–30+ years. Their resistance to chemicals, punctures, and tears ensures consistent protection with minimal maintenance required.

5. Energy Efficiency

White or reflective single ply membranes help reduce heat absorption, keeping building interiors cooler and reducing reliance on air conditioning—ideal for achieving energy efficiency goals.

6. Environmentally Friendly

Many single ply options, like TPO and PVC membranes, are recyclable and low in volatile organic compounds (VOCs), supporting green building standards and sustainability initiatives.

7. Cost-Effective Over Time

Though the initial investment may vary, the reduced maintenance, energy savings, and long life expectancy make single ply membranes a smart, long-term roofing solution.

Materials Used in Flex Membranes Roofing Systems

Flex Membranes are manufactured using advanced thermoplastic materials engineered for high performance and long-term durability. The primary materials include PVC (Polyvinyl Chloride), known for its excellent resistance to chemicals, UV rays, and fire, making it ideal for demanding environments like industrial and commercial roofs. Many of these PVC membranes are enhanced with Elvaloy® KEE (Ketone Ethylene Ester), a premium additive that improves flexibility, extends lifespan, and resists plasticizer migration. Flex also offers TPO (Thermoplastic Polyolefin) membranes, which are energy-efficient, highly reflective, and environmentally friendly—perfect for sustainable building projects. Some systems include a fleece backing for added cushioning and improved adhesion, especially useful on uneven or retrofit surfaces. To further reinforce strength and durability, most Flex membranes are embedded with a fiberglass or polyester scrim, increasing their resistance to punctures, tears, and foot traffic. Together, these materials ensure Flex Membranes deliver reliable, long-lasting performance across a wide range of roofing applications.

Applications of Flex Membranes

Flex Membranes are versatile and suitable for various roofing scenarios, including:​

• Commercial Buildings: Providing robust protection for flat and low-slope roofs.​
• Residential Projects: Enhancing energy efficiency and longevity of home roofing systems.

• Industrial Facilities: Offering resistance against chemicals and extreme temperatures.​

   

Selecting the Right Flex Membrane

When choosing the appropriate Flex Membrane for your project, consider the following:

• Project Scope: Assess the size and complexity of the roofing area.
• Installation Preferences: Determine if a traditional or self-adhered membrane suits your installation capabilities.​
• Environmental Factors: Consider the local climate and potential exposure to chemicals or pollutants.

• Our team at Insulation4US is available to help you select the ideal membrane to meet your specific needs.

   

Guidance on Selection

When choosing the Flex Membrane, consider the nature of your project and specific requirements. For standard roofing applications, TPO Plus Roof Membranes will serve excellently, providing a robust and flexible covering. However, if ease of installation is a priority, opting for TPO Plus Self-Adhered Roof Membranes would be more beneficial due to their adhesive backing, reducing installation time and effort.

Before making a selection, it’s also crucial to consider the size requirements, as all products in this category are available in various sizes to accommodate different project scales. By evaluating your project's scope and demands, you can ensure the selected Flex Membrane will provide optimal performance and protection.

Remember, each product under the Flex Membranes category on insulation4us is designed to meet high standards of quality, ensuring that your roofing and insulation needs are met efficiently and effectively.
