Pre-selected high-performance moisture-proof doors calibrated for Spanish Building Code (CTE) compliance.
In Spain, regional microclimates range from the high humidity of Mediterranean tourist zones (e.g., Costa Brava, Balearic Islands, Andalusia) to the variable oceanic weather of the Basque Country. Traditional timber doors in these regions are highly susceptible to moisture absorption, leading to warping, fungal rot, and deterioration within hotel bathrooms, resort facilities, and residential complexes.
Under the Spanish Código Técnico de la Edificación (CTE), moisture control, fire safety (DB-SI), and indoor air quality are primary compliance requirements. Premium Wood-Plastic Composite (WPC) doors have emerged as the standard alternative. They fuse natural wood fibers with thermoplastic polymers to create a 100% waterproof interior door that resists structural swelling, completely resolves issues related to termite infestation, and provides excellent acoustic dampening (up to 32dB with hollow or solid-core structural fills).

WPC Doors are optimized for Spain's building structures, architectural designs, and climate demands.
Coastal hotels along Costa del Sol, Ibiza, and Mallorca see high bathroom usage and continuous moisture exposure. Our WPC doors keep structural integrity over decades of guest use, keeping maintenance costs near zero.
For residential properties in metropolitan Madrid or Barcelona, WPC doors fulfill eco-friendly indoor requirements. Free from volatile organic compounds (VOCs) and formaldehyde, they are ideal for green residential builds.
Larsom WPC doors resist impact, chemical sanitizers, and high daily traffic, making them an excellent choice for medical clinics, regional schools, and public administration facilities across Spain.

Traditional wood doors absorb atmospheric moisture, resulting in expansion, peeling finishes, and frame distortion. Larsom WPC doors are engineered with a wood-plastic polymer compound that limits moisture absorption to under 0.5%, preventing swelling or structural deformation.
Yes. Our WPC doors meet European standards for interior construction materials. We supply fire-resistant cores that satisfy CTE Class B-s1, d0 standards, which limit smoke emission and prevent flame spread.
We provide full OEM and ODM services. Spanish builders can specify custom heights, widths, frame sizes, and lock configurations. Surface finishes include wood-grain textures, heat-transfer designs, and modern UV-protected paint finishes.
Our 16,000 sqm automated factory enables a prompt production cycle. Depending on order size, typical transit times to major Spanish ports (Valencia, Barcelona, Bilbao) range from 28 to 35 days, with container tracking available.
Our hollow-core WPC doors provide moderate sound dampening (22-26dB). For premium hotels and residential projects requiring higher acoustic control, we offer solid-core composite configurations that achieve sound reduction ratings up to 32dB.
Yes. Our materials incorporate agricultural byproducts and recycled polymer bases, reducing reliance on virgin timber. They achieve E0-grade ratings for formaldehyde emissions, supporting eco-friendly building certifications like BREEAM-ES and LEED.
