1. Based on national averages determined using RSMeans database for each material at a nominal thickness
required to achieve a thermal performance of R- 12. Because building code requirements can differ by
region, potential material/labor costs and associated savings can vary. It is important to follow building
codes and standards for your respective region.

5. R-Values vary by insulation type. Check your seller’s fact sheet for specific R-Values when comparing
6. When a minimum of 1” is applied, closed-cell SPF qualifies as an air barrier according to ASTM E-2178
which is the test used by the Air Barrier Association of America (ABAA) to define an air barrier.
7. Two inches of closed-cell SPF qualifies as a 1 perm vapor retarder according to ASTM E-96. Perm
ratings vary by manufacturer; please consult manufacturer literature.
8. Determined by Banwell Architects and GWR Engineering project assessment. $6.85/sq ft is the
difference between HVAC savings minus insulation package costs. Project total was 138,000 sq ft
(addition + renovation) resulting in total project savings of approx. $946,000
Insulation System Cost References (based on RSMeans national averages):
1. Transition detailing: Window flashing and expansion joint detailing for ccSPF ($0.43).
2. Seam (sheathing) tape: Tape to seal joints between insulation boards: ($0.21).
3. Water/Air barrier: Average cost for sheet adhesive membrane ($2.91) or modified bitumen fluid applied
($2.60) waterproofing systems. ($2.91+$2.60/2= $2.76). Sheet adhesive membrane is defined as PE/PVC
sheet + bitumen adhesive backing.
4. Insulation costs: For min. R- 12 (installed cost):
i. ccSPF 2” (R12.5)-$2.39
ii. XPS 2. 5” (R12.5) -$1.87
iii. EPS 3” (R12)-$1.76
iv. PIR 2” (R12.5)-$1.62
v. Mineral (rock) wool 3” (R12)-$2.52

Mass wall systems are durable, can easily be constructed and finished with multiple veneer claddings for a range of aesthetic and architectural
detailing. They can be professionally finished
with a variety of brick, stone, stucco or metal
claddings offering a versatile, low-maintenance
and cost-effective building design. Mass walls
are desirable because they offer the added benefit of heat capacity which buffers temperature
fluctuations and may limit peak HVAC loads.
This improves occupant comfort and can lower
energy consumption, making them attractive
for use in many commercial designs.
When designing or specifying a masonry/mass
wall, one key component is the insulation system which ultimately impacts the overall wall
system performance. With its multi-functionality, ccSPF provides an all-in-one insulation
system that meets exterior wall design criteria,
offers superior performance and simplifies the
construction process resulting in a cost-effective, yet high-performance system. By selecting
ccSPF as the insulation system; designers, owners and general contractors can simplify their
designs. This can lead to significant advantages
associated with overall system cost reductions,
improved project scheduling efficiencies and
fewer trades when compared to other insulation
