Technical desk
Reach application engineers for R-value packages, roofing assembly guidance, and certified contractor referrals. Include climate zone, fire resistance rating goals, deck type, and VOC emissions limits so we can route your note to the correct product desk within one business day. Domestic mill lead times, import-facing options, and prefabricated panel versus traditional cavity fills are routed to separate desks—do not assume a single inbox covers all product families.
When the binding constraint is thermal bridging at slab edges or air permeability at curtain-wall transitions, say so in the subject line. Teams chasing embodied carbon or recycled content percentage targets should attach the owner’s LEED / green-spec language so we pair facings and board grades before submittals freeze. Requests that only list “insulation” without service temperature, compressive strength class, or membrane type return a clarifying checklist rather than a generic catalog dump.

After-hours voicemail is reviewed at 08:00 MT next business day. Warranty claim intake for certified applicators uses a separate ticket path—state “warranty” in the subject if the roof or mechanical jacket is already installed.
Attach climate-zone maps or energy-model excerpts showing target R-value (ft²·°F·h/BTU), wall/roof sections noting continuous insulation thickness, and any UL/FM assembly IDs already selected. For HVAC work, list service temperature ranges and whether duct liner or wrap is preferred; for cold storage, note freezer setpoint and vapor-barrier orientation. Moisture vapor transmission assumptions fail when facing orientation is omitted—include that detail even on short RFIs.
Aesthetics-first cladding packages and performance-first CI stacks often conflict on thickness and fastener pattern. Flag which side currently owns the decision so we do not over-specify board density that the cladding system cannot accept. Green-premium recycled-content boards versus budget-code mineral wool are both stocked; state the cost path so sample kits match the bid set.
Use this full contact form for data packages—not the compact modal used on product cards. Include jurisdiction, assembly type, and whether you need comparative R-value tables, roofing warranty outlines, or certified contractor referrals for faster routing.
