Each year, billions of square feet of single-ply membranes are used to waterproof buildings with flat or low-slope decks. Single-ply membranes are flexible, easy to install, and cost effective, making them an ideal choice for both new build and refurbishment projects.
The main types of single-ply membranes are EPDM (Ethylene Propylene Diene Monomer), TPO (Thermoplastic Polyolefin), and PVC/KEE (Polyvinyl Chloride/Ketone Ethylene Ester). Supplied in both unbacked and fleece-backed varieties, each membrane type has specific properties that affect how it can be adhered.
H.B. Fuller develops and manufactures a wide variety of solutions to adhere both un-backed and fleece-backed waterproofing membranes. Our range consists of high-performance adhesives for fleece membranes, whilst our non-backed adhesives have been formulated to account for the properties of each specific membrane type. Our range also includes primers, developed to improve the adhesion properties of a wide range of substrates, and a full line of waterproofing tapes, flashings, and sealants developed for the different membrane types.
EPDM membranes are synthetic rubber membranes that are highly flexible and resistant to weathering and UV rays. They are typically black or white, with a long lifespan. Our EPDM range consists of:
TPO membranes are made from a blend of polypropylene and ethylene-propylene rubber, creating a durable, flexible, and energy-efficient roofing solution. They are known for their strong resistance to UV rays, chemicals, and weathering. Our TPO range includes:
Made from polyvinyl chloride and plasticizers, PVC membranes are flexible and durable plastic membranes with excellent chemical resistance and superior waterproofing properties. Ketone Ethylene Ester (KEE), a high-performance, solid plasticizer, is often blended with PVC to enhance the durability of the roofing membranes.
PVC/KEE membranes contain plasticizers, which provide flexibility but can also affect adhesion. Our range of bonding adhesives have been chemically formulated for the unique properties of non-backed PVC/KEE membranes. Various technologies and application systems are available.
We also offer a variety of primers developed to improve the adhesion properties of a wide range of substrates.
EPDM, TPO, and PVC/KEE membranes can be reinforced with a fleece backing attached to the underside. This fleece backing enhances strength, durability, and impact resistance.
The fleece backing improves adhesion, as the membrane type doesn’t affect the adhesive used. They bond effectively with a variety of adhesives, even over rough or irregular surfaces. Our bonding adhesives have been developed specifically for securing fleece-backed membranes to a range of roof substrates. Various technologies and application systems are available.
We also offer a variety of primers developed to improve the adhesion properties of a wide range of substrates.
Benefits of Bonding Single Ply Membranes
Attaching single-ply membranes using powerful adhesives secures the membrane across the entire roofing assembly, without piercing the membrane or penetrating the deck. Adhered systems have been proven to be high-performing and long-lasting, enhancing resistance to high-wind uplift and minimize thermal bridging, ultimately improving building energy efficiency. They lay flat and there are no visible fixings, making them the ideal choice for roofs that are in public view.
