With a legacy of 50-plus years, Gaco’s GacoFlex LM60 knows how to stand the test of time, having waterproofed millions of square feet of horizontal and vertical surfaces on some of the most sophisticated and aesthetically demanding structures. GacoFlex LM60 is a cold-applied, one-coat, monolithic waterproofing membrane for various surfaces, including underlayment for vegetative roofs. A 100% polyurethane, solvent-free, liquid-applied, two-component coating, GacoFlex LM60 is easy to use — requiring a single application with a squeegee, trowel, spray or brush. Since the LM60 polyurethane waterproof coating is NSF P151 Certified, it is safe for biodiversity and won’t impart contaminants into the water draining from a garden roof.

Carlisle’s MiraDRAIN products are easy-to-install products designed explicitly for vegetated roofs. The MiraDRAIN G4 Drainage Composite combines filter fabric, moisture retention mat, drainage board, and heavy-duty protection fabric for excellent drainage rates and water-holding capacity. Its high compressive strength allows a multitude of overburden options to be used, including pavers or traditional ballast, for alternative stormwater retention systems. The MiraDRAIN 9800 is a high-performance drainage composite consisting of a heavy-weight nonwoven filter fabric bonded to the individual dimples of a molded polypropylene core. It is available in rolls 4 feet wide by 50 feet long.

The FiberTite Green Roof System is an environmentally-friendly vegetative roof system offering many benefits, from stormwater control and cleaner air to reducing the urban heat island effect and improving energy efficiency. FiberTite membranes contain a thermoplastic material that provides a molecularly welded seam 10 times stronger than a glued or taped seam. Combined with its DuPont Elvaloy compound, it provides superior chemical and microbial resistance. FiberTite offers rooftop garden systems that can be installed over a metal deck or as a modular system. Both systems adhere to concrete and other deck types.

SOPRADRAIN Ecovent 2 uses a geometric patterned core drainage mat to eliminate hydrostatic pressure on vegetated roofs, foundation walls, retaining walls, planters and plaza decks. It also protects a roof’s waterproof membrane. The underside is surfaced with a heat-laminated protective fabric, while the topside includes a heat-laminated filter fabric. It’s likewise easy to install: unroll SOPRADRAIN Ecovent 2 onto the designated surface with the black filter fabric facing up. The product is ideal with SOPREMA’s SOPRANATURE vegetated roof systems to create roofs with stormwater management, mitigating “heat island” effects and increasing energy-saving benefits.

IKO offers cover boards providing strength and durability in various roofing applications; they are compatible with many types of commercial roofing systems. Protectoboard is composed of a mineral-fortified asphaltic core between two non-woven glass fiber mats. IKO says it is an ideal product for reroofs or as a new substrate for modified bitumen or BUR. IKOTherm CoverShield is a rigid foamed plastic polyiso board with non-organic coated glass fiber facers. IKO manufactures a high-density (HD) polyisocyanurate cover board with high compressive strength, IKOTherm CoverShield HD. IKO can help comply with individual commercial roofing cover board specifications.

SOPRABOARD asphaltic cover board is a semi-rigid roofing substrate board used in multi-ply membrane and flashing assemblies; it also serves as a protection board for waterproofing applications. SOPRABOARD contains a mineral-fortified asphaltic core formed between two fiberglass reinforcing plies. It is lightweight for easy handling and cutting with less breakage. Asphalt-to-asphalt compatibility results in some of the highest wind and fire-rated assemblies without the need for priming in most applications. 2-1 SOPRASMART BOARD combines SBS-modified bitumen base membrane and SOPRABOARD for time- and labor-saving solutions in approved multi-ply membrane assemblies.

Mule-Hide Products Co. has a cover board to suit any low-slope roofing system. Contractors can choose from Mule-Hide, USG Securock® and DensDeck® by Georgia-Pacific Gypsum products that are compatible with single-ply systems (fully adhered, mechanically attached, induction-welded and ballasted) and modified bitumen systems in new construction, replacement, and recover applications. The wide product assortment allows the creation of systems that meet specifications requiring increased R-Value, increased fire resistance, enhanced moisture resistance, higher wind-uplift ratings, and FM Severe Hail and Very Severe Hail classifications.

DensDeck StormX Prime Roof Board is the first high-performance gypsum roof cover board designed to help prepare commercial rooftops to hold tough under the dangers of impact and puncture caused by very severe hail conditions. The product is classified for use in approved assemblies meeting FM Global’s Very Severe Hail Standard set in 2018. According to Georgia-Pacific, DensDeck Roof Boards have a non-combustible gypsum core that helps mitigate common roof risks like puncture damage from foot traffic and maintenance — while also providing enhanced protection against fire. DensDeck StormX Prime Roof Board is for fully-adhered, partially-adhered, and mechanically-fastened assemblies.
