Since 1932 we have manufactured glass mineral wool and fiberglass insulation for builders who need consistent R-value, documented VOC emissions, and plants that ship on production schedules—including our North American presence around Inwood, WV.
Early furnaces established the thermal conductivity discipline that still governs batt density and board compressive strength today. Builders needed insulation that held thickness after transport—not loft that collapsed in the bag.
Forty manufacturing plants across roughly forty countries allowed specification writers to reference the same EcoBatt and Earthwool families on multinational portfolios without rewriting performance language per market.
Plant-based binders reduced reliance on traditional formaldehyde-heavy recipes while preserving dimensional stability. Indoor air Comfort Gold and GREENGUARD Gold documentation followed for teams chasing LEED credit pathways.
Blown-in and batt distribution strengthened for production builders who cannot wait on coastal import queues when attic R-38 fills are on the critical path.
We publish R-value per thickness and discuss thermal bridging trade-offs at steel studs instead of claiming magic continuous coverage from cavity products alone.
Bag labeling, compression guidance, and density targets for blown-in fills are written for crews who install under schedule pressure—not laboratory ideal cases only.
Mineral wool and fiberglass solve different fire and moisture contexts. When a spray foam or continuous board is the better envelope answer, our specialists say so.
Regional technical and commercial leads who talk daily with general contractors, insulation subcontractors, and sustainability consultants.
Embodied carbon worksheets and recycled content percentage statements are available on request for projects weighing sustainability mandates against budget pragmatism—especially affordable housing scopes where green premiums face hard caps.
Whether you need EcoBatt R-19 for climate zone 4 walls or mineral wool for acoustic demising assemblies, we answer with product data—not slogans.
