(everything you need to know, with real numbers, engineering logic, and plain human language)<\/em><\/p>\n\n\n\n

When we talk about prefab homes, there are usually two camps. Some see them as \u201ccatalog houses,\u201d while others see them as the future of construction. The truth is that a modern, precision-built prefab timber home is an engineering solution to many of the problems of traditional construction\u2014from uneven walls and wet construction processes to high utility bills and a massive carbon footprint.<\/p>\n\n\n\n

In this article, we will show what a modern prefab home at MODERA HOUSE<\/strong> really is, what technical advantages it offers, and how those advantages translate into lower costs and better comfort.<\/p>\n\n\n\n

1. What does \u201cprefab\u201d mean in the modern sense?<\/strong><\/h3>\n\n\n\n

\u201cPrefab\u201d comes from prefabricated<\/strong>. For us, this means that the main elements of the house are produced in a factory under controlled conditions:<\/p>\n\n\n\n

    \n
  • The architectural design is turned into a digital 3D model<\/strong>.<\/li>\n\n\n\n
  • The model is divided into panels, which are cut on CNC machines<\/strong> with millimetre precision.<\/li>\n\n\n\n
  • Insulation is machine-blown, and membranes and installations are fitted under strict quality control.<\/li>\n\n\n\n
  • Ready-made panels arrive on-site and are assembled in just a few days.<\/li>\n<\/ul>\n\n\n\n

    2. The timber structure: Why KVH C24?<\/strong><\/h3>\n\n\n\n

    The foundation of our homes is KVH C24 structural timber<\/strong>. These are beams that are technically kiln-dried and calibrated<\/strong>.<\/p>\n\n\n\n

      \n
    • Controlled moisture content (15% \u00b1 3%)<\/strong>: The beams do not shrink or twist.<\/li>\n\n\n\n
    • Strength<\/strong>: C24 class<\/strong> guarantees a bending strength of 24 MPa<\/strong> \u2014 the engineer knows exactly how much load each beam can carry.<\/li>\n\n\n\n
    • Insulation<\/strong>: Wood has a much lower thermal conductivity (\u03bb)<\/strong> than concrete (approx. 0.12\u20130.18 W\/mK vs. approx. 2 W\/mK for concrete<\/strong>), which means the structure itself also works as an insulator.<\/li>\n<\/ul>\n\n\n\n

      3. Anatomy of a modern prefab wall<\/strong><\/h3>\n\n\n\n

      Our wall is a multi-layer panel<\/strong>, where each layer has a specific function:<\/p>\n\n\n\n

        \n
      1. Inner layer<\/strong>: Knauf gypsum fibre board<\/strong> \u2014 stronger than standard drywall, providing fire protection<\/strong> and acoustic performance<\/strong>.<\/li>\n\n\n\n
      2. Service layer<\/strong>: EGGER OSB boards<\/strong> and a service cavity for cables and pipes, often complemented with STEICO wood-fibre boards<\/strong>.<\/li>\n\n\n\n
      3. Core<\/strong>: KVH C24 timber beams<\/strong>, with ISOCELL cellulose insulation<\/strong> blown in between them (\u03bb \u2248 0.039 W\/mK<\/strong>). It fills every cavity without thermal bridges.<\/li>\n\n\n\n
      4. Outer shell<\/strong>: STEICO Special Dry wood-fibre boards<\/strong> \u2014 wind-tight, but diffusion-open<\/strong> (allowing moisture to escape outward).<\/li>\n\n\n\n
      5. Facade<\/strong>: BAUMIT mineral render<\/strong> \u2014 durable and vapour-permeable.<\/li>\n<\/ol>\n\n\n\n

        4. Airtightness: \u041c\u0435\u043c\u0431\u0440\u0430\u043d\u0438 \u0438 \u043b\u0435\u043d\u0442\u0438 Rothoblaas<\/strong><\/h3>\n\n\n\n

        Thick insulation is not enough if air is \u201cleaking\u201d through the joints. That is why we use Rothoblaas systems<\/strong>:<\/p>\n\n\n\n

          \n
        • Vapour barrier on the inside<\/strong>: Prevents moisture from indoor spaces from entering the insulation.<\/li>\n\n\n\n
        • Wind protection on the outside<\/strong>: Stops wind and rain, while allowing the structure to \u201cbreathe.\u201d<\/li>\n\n\n\n
        • Result<\/strong>: No drafts, no condensation, and no mould.<\/li>\n<\/ul>\n\n\n\n

          5. The numbers that matter: U-value and kWh\/m\u00b2<\/strong><\/h3>\n\n\n\n
            \n
          • U-value<\/strong>: Shows how much heat passes through the wall. The lower it is, the better. Our walls reach levels of 0.10\u20130.20 W\/m\u00b2K<\/strong>, which is in the low-energy home<\/strong> standard range.<\/li>\n\n\n\n
          • Annual energy consumption (kWh\/m\u00b2\u00b7year)<\/strong>: A standard house typically consumes 120\u2013180 kWh\/m\u00b2<\/strong>, while our projects target a range of below 35\u201350 kWh\/m\u00b2<\/strong>.<\/li>\n<\/ul>\n\n\n\n
            \n

            Real example:<\/strong> Our show home (77 m\u00b2)<\/strong> maintained 22\u00b0C<\/strong> during the coldest month (December\u2013January<\/strong>) with a heating bill (heat pump<\/strong>) and lighting cost of only BGN 162<\/strong>.<\/p>\n<\/blockquote>\n\n\n\n

            6. The quality of what you don\u2019t see<\/strong><\/h3>\n\n\n\n
              \n
            • Blower Door test<\/strong>: We measure airtightness<\/strong> (the n50 coefficient<\/strong>). We target values below 1.0\u20131.5<\/strong>, which means minimal heat loss.<\/li>\n\n\n\n
            • Installations<\/strong>: We use Legrand electrical systems<\/strong> (with smart home capability) and Viega \/ Pipelife plumbing systems<\/strong> with press fittings<\/strong> for virtually zero risk of leaks.<\/li>\n\n\n\n
            • Foundation<\/strong>: We use industrial reusable formwork<\/strong> for perfectly smooth and precise concrete.<\/li>\n<\/ul>\n\n\n\n

              7. Ecology and sustainability<\/strong><\/h3>\n\n\n\n

              Wood stores carbon \u2014 1 m\u00b3 of timber \u201clocks in\u201d about 0.84 tonnes of CO\u2082<\/strong>. By choosing a timber home, you help reduce emissions and use PEFC-certified materials<\/strong> sourced from sustainably managed forests.<\/p>\n\n\n\n

              What do you gain with MODERA HOUSE?<\/strong><\/h2>\n\n\n\n
                \n
              1. Control<\/strong>: Factory-level quality with no \u201ccontractor-style\u201d improvisation.<\/li>\n\n\n\n
              2. Bills<\/strong>: Dramatically lower energy costs.<\/li>\n\n\n\n
              3. Comfort<\/strong>: A stable indoor climate with no drafts or cold corners.<\/li>\n\n\n\n
              4. Speed<\/strong>: Assembly in days, not years.<\/li>\n\n\n\n
              5. Peace of mind<\/strong>: A predictable process and fixed parameters.<\/li>\n<\/ol>\n\n\n\n
