High-Performance Underlayment Solutions

Sekisui Voltek provides high-performance underlayment solutions tailored for the flooring industry, addressing the need for durable materials capable of withstanding long-term foot traffic. Central to SEKISUI Voltek’s product line is Volara®, a closed-cell, irradiation crosslinked polyolefin foam known for its superior aesthetic and functional properties. Volara’s smooth surface, consistent density, and low water absorption make it ideal for a wide range of flooring applications, including laminate, carpet underlay, tile, and specialty flooring.

Volara excels in impact absorption and sound insulation, making it a reliable underlayment that enhances flooring performance by minimizing sound transmission and compensating for surface imperfections. Volara’s elasticity and conformability help prevent unwanted noise and structural inconsistencies by encapsulating small floor irregularities. Various Volara types offer different benefits:

• Type A for Cost-Effective Multipurpose Use
• Type LM for Improved Performance and Heat Stability
• Types LS, RS, and VS for Superior Strength and Low-Temperature Moldability

Volara also meets environmental standards. Select grades manufactured at the Coldwater facility are tested quarterly under the Carpet and Rug Institute’s Green Label Program, ensuring low VOC emissions and compliance with stringent environmental criteria.

Volextra®, an advanced product that integrates Volara foam with a variety of surface coatings, further enhances performance. Volextra offers improved thermal insulation, decorative finishes, and customized surface properties using coatings such as LDPE, HDPE, EVA, and others. Volextra is available in multiple thicknesses and finishes, offering design flexibility and advanced functional performance.

In terms of insulation, Sekisui Voltek considers both K (thermal conductivity) and R (resistance) factors in foam performance. While denser foams typically provide lower insulation values, precise engineering allows for optimal material design.

Sekisui Voltek also emphasizes innovation and customer service. With dedicated R&D, in-house testing facilities, and a global product range, we support our customers through technical expertise, fabrication capabilities, and collaborative development. R & D’s approach combines cutting-edge technology with market responsiveness, ensuring SEKISUI Voltek’s polyolefin foams meet evolving industry demands with superior performance, reliability, and sustainability.
