- Closed-cell spray foam providing an R-value of 6.5 per inch.
4.7 Division 07 – Thermal and Moisture Protection
07 13 52 Below Grade Waterproofing: Modified bitumen membr ane- HPR Torcha ble Base Sheet.
- Finished Membrane Stressply IV Mineral.
07 20 00 Building Insulation- Batt insulation to be installed in all interior walls for increased sound absorption. Insulation to be unfaced,
fiberglass batt, formaldehyde free.
07 22 16 Roof Board Insulation
Specify by thickness (not R-vlaue), with the thickness ensuring sufficient R-value to meet the energy code. Consider
R-value in addition to the energy code where appropriate (review with the UIHC Project Manager).
Polyisocyanurate insulation (20 psi minimum) shall be sued for thermal insulation. Use 2014 LTTR value for
polyisocyanurate R-value. In applications without vapor retarders, mechanically fasten to steel decks with 3" Galvalume
plates and fasteners, and adhere to concrete decks using low rise polyurethane foam adhesive.
A high density 1/2" minimum cover board shall be used over the thermal insulation to increase hail, puncture, and wind
uplift resistance. The preferred method of application is to adhere using low rise polyurethane foam adhesive, however
the assembly must meet FM Global RoofNav assembly requirements. Gypsum or high density polyisocyanurate
coverboards are approved. Gypsum coverboards are preferred for adhered applications, with either gypsum or high
density polyisocyanurate coverboard allowed for mechanically fastened applications. Perlite, wood fiberboard, or
fiberglass shall not be used for coverboards.
If a vapor retarder is required over a steel deck, an appropriate gypsum roof substrate board shall first be mechanically
fastened to provide a substrate for the vapor retarder. After the vapor retarder is installed, subsequent insulation and
coverboard shall be adhered to the vapor retarder. If a vapor retarder is required over a concrete deck, the vapor retarder
shall be adhered to the concrete, followed by adhered insulation and coverboard.
Perimeter and corner enhancements to insulation system attachments shall be specified by the Design Professional as
required to meet FM Global and ASCE/SEI 7-10 standards, whichever is more stringent.07 26 00 Vapo r Retarde rs
Wall s sha ll be designe d to mini mize moi stur e wicking and growth of mold. Use of organic materials shall be avoided.
The Design Professional shall demonstrate the appropriate use of vapor barriers. The Design Professional shall evaluate
the need for a vapor retarder within the new roof assembly, by considering the interior and exterior temperatures,
anticipated interior relative humidity, interior occupancies and processes, and location of dew point within the roof
assembly during anticipated January temperatures. Where applicable, a vapor retarder with continuous functional
flashing systems, shall be designed on the warm side of the roof assembly, with sufficient insulation specified to
