Buyer's Specification Guide
From years of supplying European projects, these are the performance values architects and building control most often ask for. Use this checklist when you brief us — we will confirm what each configuration can achieve.
| Performance | European Standard | Why It Matters | How DERCHI Supports You |
|---|---|---|---|
| Product Standard & CE Marking | EN 14351-1 | The harmonised standard for external pedestrian doors placed on the EU market. | CE-certified products with project documentation for your declaration of performance. |
| Thermal Transmittance (UD) | EN ISO 10077 | National energy rules such as Germany's GEG or UK Part L set maximum U-values. | Thermally broken profiles, insulated cores and triple-glazing options; values calculated per door size. |
| Burglar Resistance | EN 1627 (RC classes) | Insurers and police guidance commonly recommend RC2 or higher for residential entrances. | Reinforced frames, multipoint locking and security glazing configured to your target class. |
| Air, Water & Wind | EN 12207 / 12208 / 12210 | Critical for exposed coastal, high-rise and Alpine locations. | Multi-seal systems and threshold details engineered for the site's exposure. |
| Acoustic Insulation | EN ISO 717-1 | Urban residences and hotels near traffic require reduced noise transfer. | Soundproof door cores and acoustic glazing for quieter interiors. |
| Fire Resistance | EN 1634-1 | Required for multi-occupancy, hotel and commercial escape routes. | Fire rated pivot and commercial door options for compartment applications. |
Achievable classifications depend on leaf size, glazing and hardware. Our engineers confirm the exact values for your door schedule before production — never after delivery.
