Building Healthy Homes with the Power of Nature
At Ecoplus, we believe that a truly valuable home must be healthy for both its occupants and the planet. Standard Japanese houses heavily rely on synthetic, low-density glass wool and petrochemical materials that degrade over time, absorb moisture, and release off-gasses into indoor air.
We choose a different path. Guided by European building science (HOLZBAU), we carefully select natural, high-density, and breathable materials. Our insulation systems don't just keep you warm—they manage humidity, block outdoor noise, store carbon, and create a pristine indoor air quality free of toxic chemicals.
CELLULOSE INSULATION
CELLULOSE INSULATION
Cellulose is an eco-friendly blow-in insulation made from recycled paper treated with natural mineral salts for fire and pest resistance.
Seamless 360° Thermal Seal: Blown in under high pressure, cellulose fills every gap, crack, and hard-to-reach corner within wall cavities and roof spaces, eliminating draft-causing thermal bridges.
Natural Humidity Control: Cellulose fibers naturally absorb and release moisture in balance with indoor humidity, acting as a natural humidity regulator inside your walls.
Fire & Pest Resistant: Treated with non-toxic boric minerals, cellulose achieves high fire-retardant ratings while naturally repelling insects and rodents without harmful chemicals.
PAVATEX Wood Fiber Insulation
Sourced from Switzerland, Pavatex is a high-density insulation board made from natural wood fibers. It represents the pinnacle of European thermal protection.
Superior Summer Heat Protection: Unlike light synthetic insulation, high-density wood fiber has incredible thermal mass (phase displacement). It absorbs intense summer heat during the day and stops it from penetrating your roof and walls.
Vapor-Permeable & Breathable: Pavatex allows moisture trapped inside walls to escape naturally to the outside, preventing internal structural rot and toxic mold growth forever.
Exceptional Soundproofing: The dense fiber structure absorbs ambient outdoor noise and rain, keeping your living space peacefully quiet.
Carbon-Negative: Wood fiber actively locks away carbon absorbed by trees, making your home a natural "carbon vault."
Smartwin High Performance Windows
Smartwin High Performance Windows
(Triple glazing)
(Triple glazing)
Windows are often a building's weakest link for heat loss. Smartwin thermal-break windows feature ultra-slim frames, triple glazing, and German Passivhaus-certified engineering. They offer unmatched insulation, eliminate cold window drafts and pane condensation, and maximize natural daylight while keeping winter cold and summer heat strictly outside.
Würth Professional Building & Airtightness Systems
The performance of a high-insulation house relies entirely on the quality of the membranes, tapes, and sealants hidden inside the walls. That is why we exclusively use Würth—Germany’s gold standard in professional building supplies.
Tested 80-Year Lifespan: Standard Japanese tapes and sealing foams often dry out, crack, or lose adhesion after just a decade. Würth’s sealing systems are rigorously certified to maintain their elasticity, adhesion, and airtightness for up to 80 years—outlasting standard building components and permanently protecting your structure.
Guaranteed Airtightness & Rot Prevention: Würth’s specialized WÜTOP vapor membranes and EURASOL sealing tapes form an impenetrable barrier against wind and drafts. This stops moisture from leaking into wall cavities, permanently protecting internal timber framing from rot and mold.
Certified Eco-Safe & Non-Toxic: Meeting the strict European EMICODE EC1 Plus standard, Würth products release zero harmful chemical off-gassing, keeping your indoor air pure and safe for generations.
Volvox Clay Paint & Shikkui Lime Plaster
Volvox Clay Paint & Shikkui Lime Plaster
Volvox German Clay Paint (Lehmfarbe): Imported from Germany, Volvox contains zero synthetic binders, chemical solvents, or plasticizers. It dries to a velvety, matte texture that remains fully microporous, allowing walls to breathe while absorbing indoor odors and neutralizing airborne pollutants.
Traditional Shikkui & Tanacream Lime Plasters: Crafted from high-purity limestone, these natural plasters possess a high alkaline pH that naturally prevents bacteria and mold growth. As the plaster cures over decades, it actively re-absorbs $\text{CO}_2$ from the surrounding room air through carbonation, hardening into a durable, fire-resistant surface with timeless aesthetic warmth.
