Contact Owens Corning Specification Specialists

Reach application engineers for R-value packages, Duration shingle wind ratings, and Preferred Contractor referrals. Include climate zone, target thermal resistance, roof slope, and whether you need Class 4 impact documentation so we can route your note to the correct product desk within one business day.

Procurement managers and specification writers typically ask for published thermal conductivity context, fire resistance rating pathways, moisture vapor transmission notes at kraft facings, and dimensional stability limits for foam board continuous insulation. Share those constraints up front—along with VOC emissions targets for GREENGUARD Gold packages—so we do not bounce your inquiry between roofing and insulation desks.

Visit / ship samples

Ship substrate coupons, shingle samples, or foam board cores for thermal and wind screening to the Toledo technical center receiving dock. Label packages with project name, target R-value or wind rating, climate zone, and whether ENERGY STAR or GREENGUARD Gold thresholds apply. Coupons must be large enough for thermal resistance specimens; roof deck samples should note existing underlayment when overlays are planned. Note Buy America or domestic-mill constraints so logistics quotes lead time in calendar days rather than catalog optimism.

Attic loosefill trials: include joist depth, ventilation net free area, and air permeability concerns at bypasses. Continuous insulation teams: mark rim-board transitions, sheathing type, and water absorption rate expectations for below-grade XPS. Panel builders: state whether insulation is factory-installed or site-packed—compression and dimensional stability checks differ. If the project needs recycled content percentage notes for a green checklist, say so; otherwise we route code-compliant standard assemblies that still clear inspector lists without inflating the material budget.
