HOUSE WRAP & UNDERLAYMENT

Oskorp GoldWrap

GoldWrap is Oskorp’s high-performance building wrap, engineered for maximum durability, energy efficiency, and long-term protection. Crafted from a 3-ply non-woven structure with a breathable polyolefin coating, this non-perforated membrane serves as both an air barrier and a water-resistive barrier in accordance with international building standards.

Core Benefits

Weather Barrier Excellence

Certified to ASTM E2556 Type II, GoldWrap deflects wind-driven rain and shields insulation from external moisture – keeping your structure dry and protected.

Highly Breathable

With a water vapor permeance of 20 perms and a vapor transmission rate of 170 g/(m²·24hr), GoldWrap enables trapped moisture vapor to escape, reducing mold risks and promoting a healthy assembly.

Air Barrier Certified

GoldWrap achieves <0.02 L/(s·m²) at 75 Pa – well below the threshold – offering superb airtightness and contributing to energy efficiency.

Tear-Resistant Strength

Tough where it counts: 50/40 lb/in tensile strength and 24/20 lbf tear resistance (MD/TD) ensures durability during installation and service life.

Non-Glare Surface

The non-reflective surface makes installation safer and more comfortable, especially in bright outdoor environments.

UV-Resistant for 6 Months

Allows flexibility on-site, giving installers time to complete cladding without compromising the wrap's integrity.

Fire Rated: Class A

Flame spread and smoke developed ratings of 0 – fully compliant with ASTM E84, making it suitable for a wide range of construction projects.

Non-Perforated Protection

Unlike perforated wraps that risk water intrusion, GoldWrap is fully non-perforated, offering uninterrupted protection against wind-driven rain—even before the cladding is installed.

FAQ

Need clarification?

What makes GoldWrap better than traditional house wraps?

GoldWrap combines non-perforated protection, Class A fire performance, and 20-perm breathability in a single wrap. It’s stronger, more airtight, and more vapor-permeable than many standard products—offering true performance in every climate zone.

How does it hold up in wet and humid climates?

Exceptionally well. GoldWrap is both a water-resistive barrier and a breathable membrane, allowing internal moisture to escape while blocking external water intrusion. It also resists mold and mildew, thanks to its synthetic construction

Can I use it behind all types of exterior siding?

Yes. GoldWrap is compatible with virtually all cladding systems—wood, vinyl, fiber cement, metal, stucco, and more. Its non-glare surface even makes installation easier and safer in bright sunlight.

How do I properly tape the seams and corners?

Use a high-performance, UV-stable tape like Oskorp’s ONE 4 ALL Tape. Ensure all overlaps are sealed tightly, especially at openings and transitions. For best results, apply tape with a roller and avoid stretching it during installation.

Is it okay to leave GoldWrap exposed for months before cladding?

Absolutely. GoldWrap is UV-resistant for up to 6 months, so it can be exposed to the elements without performance loss while your project progresses
