Critical Contractor & Job-Site Advantages
Integrated Vapor Retarder: The kraft paper facing functions as a Class II vapor retarder, stopping moist interior air from condensing on cold exterior sheathing during heating seasons.
Enhanced Acoustic Isolation: Absorbs low and mid-frequency sound waves, significantly boosting the Sound Transmission Class (STC) rating of interior drywall partition walls.
Dust-Reduced Handling: Formulated with an advanced resin binder that minimizes airborne fibers and dust during cutting and placement, improving crew comfort on site.
Where Can Glass Wool Insulation with Kraft Faced Be Used?
1. Exterior Stud Walls (Residential & Light Commercial)
Fills stud bays in residential framing (2x4 / 2x6). Installed with the kraft paper facing turned toward the warm/conditioned living space to limit moisture migration.
2. Attics, Floor Joists & Cathedral Ceilings
Laid between joists and floor systems above unconditioned crawlspaces or unheated basements, preventing floor coldness and damp air penetration.
3. Soundproofing Partition Walls
Placed within interior drywall partitions in office buildings, hotels, and multi-family apartments to reduce room-to-room noise transfer.
Quality-Focused Manufacturing
ECOFOX manufactures insulation materials with a focus on stable product quality and consistent production. The glass wool core is produced through controlled manufacturing processes, followed by forming, cutting, facing, inspection, and packaging.
For glass wool insulation with kraft faced, the bonding between the glass wool core and kraft paper is an important part of the finished product. Production inspection helps maintain a consistent appearance, dimensions, facing condition, and overall product quality.
ECOFOX operates more than 13 glass wool production lines to support both regular distribution orders and project-based requirements. Production capacity allows us to supply container-volume orders for international customers while maintaining flexibility for different product specifications.
Our manufacturing and export teams work together to coordinate production, packaging, container loading, and shipment arrangements. This allows overseas distributors, contractors, insulation wholesalers, and project buyers to communicate their requirements directly with the factory.

Direct-factory purchasing gives you clear communication, guaranteed production schedules, and competitive pricing. Contact the ECOFOX team today for technical submittals and product samples.
