“SPF 100”A Presentation to:CHBATechnical Research Committee (TRC)October 22, 2010 Peter BirkbeckIcynene Inc. – Codes and Standards
Icynene Inc. • a Canadian company located in Mississauga ON • ICYNENE LD-C-50® (formerly Gold Seal®) invented in Canada in 1986 • distributors/installers (dealers) in over 20 countries worldwide
Spray Foam Types • 3 basic types of SPF used in residential and commercial construction: • High density 3lb. + (closed cell): roofing • Medium density 2 lb. (closed cell) • Low density 0.5 lb. (open cell): Icynene, etc. • All SPF is good…
Spray Foam Types • Medium density SPF (ccSPF) • Closed cell structure: rigid, non-flexible • Air and vapour barrier material • At what thickness? • High R-value but stabilizes over time: “LTTR” • Water-resistive barrier • Formulated with chemical blowing agents • Must be applied in multiple passes • (more later)
Spray Foam Types • Low Density SPF (ocSPF) • Semi-flexible: more resistant to movement of structure • Air barrier material • usually (check), at what thickness? • Vapour barrier material: no (not in Canada) • Stable R-value • Can absorb water but allows drainage • Water-blown (usually)
Thermal Barrier NBC 2005 (9.10.17.10) • (all) “..foam plastics…shall be protected from adjacent space…, by,” • “..finishes described in Subsections 9.29.4 to 9.29.9.,” • “sheet metal mechanically fastened..” • “any thermal barrier meeting the requirements of Clause 3.1.5.12.(2)(e).” (Class B of CAN4-S124-M test)
Product Compliance • NBC 2005 • CAN/ULC standards S705.1 and S705.2 are for ccSPF • do not apply to ocSPF • similar standards for ocSPF under development (S712.1 and S712.2)
Sealing Problem Areas Rim and Band Joists All stud spaces
Accommodating Complex Construction Windows Metal Stud Channels Wide stud spaces
SPF Installation • ccSPF: per CAN/ULC S705.2 • Trained installer required • Each pass between 15 and 50 mm • Exotherm risk • ocSPF • CCMC Technical Guide: trained installer required • No limit on pass thickness: up to 300 mm • Installation standard (S712.2) under development
Product Compliance • CCMC Evaluations • (-R) non-standardized materials - meet the intent of the Codes • (-L) listing: meets recognized standard ie. S705.1 • Current count (CCMC Registry): • 4 ccSPF • 6 ocSPF • For example: • NBC: CCMC 12070-R: ICYNENE LD-C-50® • OBC (ON) Minister’s Ruling: if proponent elects
Emerging issues:Where you could help.. • Ask for proof: • Of trained installer • Of product compliance • Building Codes: resist: • Increasing R-values that limit product choices • Prescriptive packages “equivalent to” EG 80 with no performance (test)
