What is the Hertalan EPDM Roofing Membrane?
Hertalan Easy Cover EPDM
What is EPDM Membrane?
EPDM membrane is a synthetic rubber enhanced with additives and subjected to a vulcanization process. It is a waterproofing material known for its complete water-tightness and durability, often measured in decades. EPDM is highly elastic, offering an elongation capacity of up to 500%, allowing it to accommodate building movements without cracking. It stands out for its resistance to UV radiation, ozone, and most chemical compounds.
EPDM membranes are ideal for diverse climates, being resistant to both high and low temperatures. Available in various thicknesses and reinforced options, EPDM membranes can be installed using different methods, such as mechanical fastening, adhesive bonding, or ballasting, depending on the type of membrane chosen.
What is the Hertalan EPDM Membrane?
The Hertalan roofing membrane is an advanced EPDM sealing system designed to protect flat roofs and other structures, whether newly constructed or undergoing renovation. Its resilience to extreme temperatures, ranging from -45°C to +120°C, combined with resistance to UV radiation, ozone, and other environmental factors, ensures long-lasting protection. Additionally, the material's exceptional elasticity allows it to stretch up to 500%, effectively handling the tensile stresses that flat roofs experience throughout their lifespan.
Hertalan EPDM stands out among other waterproofing membranes for its remarkable durability, as confirmed by the Southern German Plastics Center (SKZ) in Würzburg. Studies show that HERTALAN EPDM systems can last over 50 years. The product has also earned the DUBO Certificate and an EPD declaration from the Dutch NIBE Certification Institute, affirming its environmentally friendly profile.
How Does the Hertalan Easy Cover Roofing Membrane Differ From Other EPDM Membranes?
The innovative HERTALAN EASY COVER system, consisting of factory-prepared EPDM sheets cut to custom dimensions, significantly reduces the need for on-site joins. This method allows for quick and straightforward application without the use of open flames while also offering root resistance compliant with FLL standards. The sheets are custom-sized according to the client's order, streamlining the installation process.
Additionally, HERTALAN EASY WELD is another advanced roofing membrane system that facilitates safe processing using hot air welding technology, eliminating the risk of fire. This product is available upon request.

Adhesives for HERTALAN EPDM Membranes
Hertalan KS96 - Single-Component MS Polymer-Based Adhesive and Sealant
HERTALAN KS 96 is a specially designed adhesive for attaching HERTALAN EPDM rubber seals to various vertical and horizontal surfaces. It is also used for sealing bonded joints along edges. This adhesive offers excellent adhesion to EPDM membranes, is water-resistant, and maintains flexibility. It is applied as a single-sided adhesive and provides thermal resistance across a wide temperature range, from -40°C to +100°C after full curing.
Application:
- HERTALAN KS 96 is ready-to-use and should not be diluted or mixed with other substances.
- Application should occur in dry weather with a minimum ambient temperature of +5°C.
- Both the EPDM material and the substrate must be dry, frost-free, and clean.
- Adhesive should be applied as two continuous beads, each with a minimum diameter of 7 mm. Do not spread the adhesive.
For sealed seams (using HERTALAN KS 137), the edge zone (20 mm wide) should be sealed with HERTALAN KS 96. Apply the adhesive using a cartridge or bag, then press the seam with a silicone pressure roller, ensuring a 1 mm wide bead of adhesive emerges from the joint.
Hertalan KS137 - Contact Adhesive
Hertalan KS 137 is a ready-to-use contact adhesive designed for bonding seams of HERTALAN EPDM sheets and rolls, as well as for surface bonding on dry, smooth, and clean substrates, such as wood, concrete, and metals (including aluminum, steel, and galvanized sheet metal). It is particularly recommended for use at connections and terminations. This adhesive provides excellent adhesion to overlapping EPDM strips and various substrates. It creates water-resistant and flexible bonds. The adhesive must always be applied on both surfaces for optimal results. After full curing, Hertalan KS 137 offers thermal resistance from approximately -40°C to +80°C.
Application:
- Hertalan KS 137 is ready-to-use and must not be diluted or mixed with foreign materials.
- Apply in dry weather conditions with an ambient temperature of at least +5°C.
- Both the EPDM material and the substrate must be clean and dry.
- Apply adhesive to both surfaces to be bonded.
