Oskorp VARISMART DUO
At Oskorp, we innovate to meet the dynamic needs of modern construction. Our OSKORP VARISMART DUO and OSKORP VARISMART DUO+ membranes set a new standard for moisture control, durability, and energy efficiency. Designed to adapt seamlessly to changing humidity conditions, these smart vapor barriers are perfect for both new construction and renovation projects.
Dynamic Moisture Adaptation
Sd-value range: 0.1 m to >20 m, equivalent to 58.1 PERMS to <0.29 PERMS.Automatically adjusts to maintain optimal moisture levels in any climate. Superior protection against condensation and structural damage.
Exceptional Durability
OSKORP VARISMART DUO+ incorporates a mesh layer, increasing its resilience and making it ideal for use with blow-in insulation materials like cellulose or fiberglass. Withstands high mechanical loads during installation, ensuring longevity.
High-Performance Composition
Multi-layer construction: Polyamide film with polypropylene (PP) fleece for the DUO and additional mesh reinforcement in the DUO+ for extra strength.
Lightweight and Easy to Install
Roll weight: Approx. 3.45 oz/ft² (105 g/m²). Tear resistance: Over 39.3 lbs/ft-width (175 N/50mm, longitudinal) and 33.7 lbs/ft-width (150 N/50mm, transverse).
Why Choose OSKORP VARISMART Membranes?
- Energy Efficiency: Optimize indoor climate control by reducing heat loss in winter and minimizing overheating in summer.
- Moisture Control: Prevents mold growth and structural decay by managing moisture flow in all weather conditions.
- Eco-Friendly: Designed for sustainable building practices, contributing to energy-efficient, green construction projects.
- Versatile Applications: Ideal for walls, roofs, and ceilings in residential and commercial construction.
- Enhanced Compatibility: Works seamlessly with other Oskorp sealing products, like DuoEasy Sealing Tape and ONE 4 ALL Tape.
The VARISMART Advantage for Blown-In Insulation
The integrated mesh layer in the VARISMART DUO+ ensures it can handle the pressure and density of blow-in insulation, keeping it securely in place without compromising the membrane's integrity. This makes it a reliable choice for contractors looking to achieve airtight and efficient installations in retrofit and high-performance construction projects.

Need clarification?
What is the difference between OSKORP VARISMART DUO and VARISMART DUO+?
The main difference is the mesh reinforcement in VARISMART DUO+, which enhances its durability and makes it ideal for use with blow-in insulation materials like cellulose or fiberglass. Both membranes offer the same smart moisture-adaptive properties and high performance.
What does the Sd-value range mean, and why is it important?
The Sd-value range (0.1 m to >20 m, or 58.1 PERMS to <0.29 PERMS) represents the membrane's ability to adapt to changing humidity conditions. It adjusts vapor permeability to ensure optimal moisture control, preventing condensation and protecting the structure from mold and decay.
Can these membranes be used in all climates?
Yes, both OSKORP VARISMART DUO and VARISMART DUO+ are designed for use in a wide range of climates, including cold, humid, and arid regions. Their adaptive Sd-value ensures consistent performance regardless of weather conditions.
Are these membranes suitable for retrofit projects?
Absolutely! Both membranes are excellent for retrofitting, with VARISMART DUO+ being particularly effective for projects involving blow-in insulation. They help enhance energy efficiency and moisture protection in older structures.
How do I install VARISMART membranes?
Installation is straightforward thanks to their lightweight and flexible design. Use Oskorp's compatible sealing tapes, such as One4All Tape, for airtight connections and optimal performance. Detailed installation guides are available upon request. We also offer training programs for contractors
