GreenGrid® Advantages |
GreenGrid® Systems |
Traditional (Built-In-Place) Systems |
| Easy Maintenance and Repair |
Modules can easily be moved and then put back in place without disturbing growing media or plantings |
Layers need to be cut and rolled back until repair location found; plants and layers damaged |
| Engineered System |
Components are engineered to work together, optimizing installation and integration |
Generally customized by project; multiple sourcing, limited production speed |
| Competitive Cost |
Competitive installed costs versus more costly leading built-in-place systems |
New roof surface plus mat, drainage, root barrier, moisture retention layers often costly |
| Quick Installation |
Delivered pre-planted, ready to set in place. Downtime due to inclement weather reduced |
Multi-layer, built-in-place, vegetation planted at job site is time-consuming |
| Preplanted System |
Pre-planted
in advance at the nursery for quick installation
time, can be pre-grown to desired plant coverage |
Roofs generally require about 2 years to be "green" |
| Lightweight |
Lightweight - installs on any existing roof surface in good condition and with structural capacity |
Systems often heavy and roof surface replacement often required to despite condition |
| Easy Placement |
All modular system components quickly put in place on roof in accordance with design |
Components delivered to rooftop by multiple sources can present scheduling nightmares |
| LEED® Certification |
All GreenGrid® modules contain recycled materials contributing to LEED® recycling credits |
Generally do not have components containing recycled materials |
| Built-In Stormwater Retention |
Module design provides built-in water retention |
Water retention layers must be added |
| Easy Alterations & Additions |
Option of installing green roof in sections offers opportunity for future add-ons and alterations |
Often difficult and expensive to change/add-on due to edge design requirements |
| Predetermined Water Retention Alternative |
Ecoballast® modules augment stormwater retention without plants and growing media |
Not Available |
| Wrap-Around Warranty |
GreenGrid® installed as part of a Mule-Hide Green Roof offers a NDL Wrap-Around Warranty |
Limited Warranty - Removal and re-installation of plants/vegetation generally not included |
