Dow Roofing Systems – Vegetative

Also called green roofs, garden roofs, eco-roofs and living roofs, vegetative roofs have a long and proven history in Europe and are gaining in popularity in North America and elsewhere. A GARDENTOP™ Roof System features advanced waterproofing membrane technology with TIEMPO™+ 2000 TPO and VIENTO™ PVC membranes. In addition, it includes a variety of high-performance, high compressive strength extruded polystyrene or polyisocyanurate insulations and water management technology designed to support the needs of a vegetative roof.

GARDENTOP™ Roof Systems may be specified for both intensive and extensive vegetative roof assemblies. The main differences between the two are depth of growing medium, and placement of the roofing membrane, insulation and drainage system.

A vegetative roof delivers many benefits to the building owner and surrounding community. Studies worldwide have clearly demonstrated that vegetative roofs make a positive impact on their local environment that ripples through the larger eco and economic systems they affect.

Vegetative roofs help:

• Clean the air of particulate matter
• Create habitat areas for indigenous wildlife
• Provide aesthetic appeal to surrounding locations
• Reduce the urban heat island effect prevalent in many metropolitan areas
• Control storm water run-off, absorbing it and then releasing it slowly

Protected from environmental exposure, like ultraviolet radiation and temperature extremes, properly installed and maintained vegetative roofs can have longer life spans than other roof types.

Dow Roofing Systems provides a full line of component products designed to work together to complete the GARDENTIOP™ Roof System assembly. Your Dow Roofing Systems sales representative can help select the best products for your vegetative roof needs.
