Salmon Creek Green Roof – Plywood Base

Square Meters: 3000 sqm
Roof System: WetSuit®

The greatly anticipated Salmon Creek Environmental Center had a goal to become the first California public K-8 school to obtain a LEED Gold Certification. The school is run by the local School District Union who set the task of building not just an award winning educational facility but a school which genuinely embraced green principles.

The green roof is the focal point of the free flowing building design. Effective waterproofing of the plywood substrate was crucial to its success.  Water based, no VOC WetSuit® membrane was chosen to aid in the establishment of LEED points, but also to meet the demands inherent in the architecturally free flowing roof design. 100 dry mils of WetSuit® was specified as well as 40 dry mils of high quality elastomeric topcoat.

The fluid applied membrane was installed directly to the plywood surface. Spray foam insulation was applied between the joists in the ceiling. The green roof was planted with cuttings started by the students.  The established roof fauna ecosystem is now self sustaining and is also integrated into the students curriculum.
