Compared to other typical single-ply EPDM, PVC and TPO membranes, GAF
EverGuard EGFB-50 roofing membrane provides the benefits of all three materials
in a single membrane:
| Consistent sheet thickness |
Compares favorably to typical TPO membranes that are significantly
thinner between scrim reinforcement. |
| Formulated with DuPont Elvaloy solid polymer |
Compares favorably to typical PVC membranes that are formulated with
liquid plasticizers and require a thicker sheet to function as a plasticizer
reservoir. |
| Competitive 76" wide membrane sheets |
Wider sheets allow faster roof system installation. |
| Polyester fleece backing |
Provides improved adhesion compared to most smooth-backed sheets.
Allows direct membrane application to rough substrate surfaces such as
structural and lightweight insulation concrete. |
| Resistant to chemicals, oils and grease |
Allows installation on industrial applications, restaurants, etc.
where chemical, oil and grease contamination would deteriorate typical
PVC and EPDM membranes.* |
| Heat-welded seams |
Heat-welded seams provide superior tensile and peel strength as well
as superior long-term performance when compared to taped or glued EPDM
membrane seams. |
| Non-wicking polyester scrim reinforcement |
Non-wicking heat-stabilized polyester scrim reinforcement eliminates
the need for seam sealants required by other PVC and TPO membrane systems. |
| Standard reflective white color |
Energy-efficient white membrane reflects significantly more solar
radiation than do typical black EPDM membranes, reducing heat load. Also
available in a light gray color. |
| Superior tear and puncture resistance |
Tear and puncture resistance is superior to that of typical unreinforced
EPDM
membranes, comparable to the performance of thicker TPO and PVC membranes. |
| FM/UL approvals |
Competitive FM/UL roof system approvals are available for installation
over both noncombustible and combustible roof decks. |
| Single-source responsibility |
All materials, including membrane, flashing, insulation, fasteners,
and accessories, are included in standard guarantee coverage, both NDL
and Dollar Per Square guarantees. |
| Proven performance |
In-field installations in all regions of the U.S. dating back 10
years. |
*Damage resulting from oil, grease, or chemicals is not covered under
EverGuard guarantee or limited warranty against manufacturing defects.
