High-performance engineering polymers optimized for the Spanish infrastructure and construction sectors.
The Spanish construction and architectural sectors have undergone a significant transformation over the last two decades. With the implementation of the Código Técnico de la Edificación (CTE), specifically the Documento Básico de Protección frente al Ruido (DB-HR), acoustic comfort has transitioned from a luxury option to a strict regulatory mandate. In this context, CE Certification Polyurethane Floating Floor Underlayment has emerged as an indispensable technology for developers, architects, and acoustic engineers across Spain.
CE marking is a critical requirement for any building material imported into or distributed within the European Economic Area (EEA). For Spanish construction sites—from the urban developments in Madrid to residential complexes in Barcelona and Valencia—CE certified polyurethane underlayments guarantee compliance with harmonized European standards, assuring performance metrics like dynamic stiffness, tensile strength, and long-term creep behavior under load.
The primary driver for the adoption of high-performance polyurethane underlayments in Spain is the DB-HR framework. This regulation defines the minimum acoustic insulation requirements for buildings, limiting both airborne noise transmission and impact sound levels. For impact noise, the regulation specifies that the weighted impact sound pressure level (L'nT,w) in habitable rooms must not exceed 65 dB. Achieving this standard in multi-family residential structures or commercial spaces requires highly elastic interfaces beneath screeds or finished floorings.
Polyurethane floating floor underlayments excel in these scenarios due to their microcellular structure. Unlike traditional materials like polyethylene foam or recycled rubber, which can compress permanently over time under static load, premium polyurethane maintains its elastic recovery properties for decades. This ensures that the acoustic performance calculated during the design phase remains consistent throughout the building's lifecycle.
Our polyurethane isolation solutions are tailored for a diverse range of local application scenarios:
Resistant to hydrolysis, chemicals, and concrete alkaline environments common in Spanish building practices.
Fully compliant with European construction product regulations, backed by rigorous third-party testing.
Engineered to isolate structural noise from metros, railways, and mechanical plant rooms in urban centers.
Advanced testing methodologies ensuring international quality standards for European and Spanish markets.
The Changmei Testing Center conducts testing activities recognized under the International Laboratory Accreditation Cooperation (ILAC) and the Asia Pacific Accreditation Cooperation (APAC) through mutual recognition arrangements.
