About the product
Knauf Therm ETIX Blanco is Knauf's stabilized EPS panel for ETICS (External Thermal Insulation Composite System) — it complies with ETAG 004 and UNE-EN 13163, dimensionally stabilized for proper performance on exterior facades. Available in 3 thicknesses: 40, 60, and 80 mm. Each box covers between 6 and 12 m² depending on the chosen thickness. Price per box.
What thickness do I need? — Quick Guide
| Thickness | R-value (m²·K/W) | Coverage per box | When to use it |
|---|---|---|---|
| 40 mm | ≈ 1.05 | 12 m² | Temperate climate · Slight efficiency improvement · Minimum Zone C |
| 60 mm | ≈ 1.57 | 8 m² | Most common thickness · Complies with CTE in most areas · Optimal performance/cost ratio |
| 80 mm | ≈ 2.10 | 6 m² | Cold climate · Zones D and E · Maximum reduction in energy demand |
λ value white EPS ≈ 0.038 W/mK. For a renovation with a demanding CTE DB HE, the designer will indicate the necessary thickness according to the climatic zone.
Why choose Knauf Therm ETIX
- ✓ Dimensionally stabilized — does not shrink or deform — Knauf's stabilization process ensures that the panel does not change its dimensions after installation; unstabilized EPS can retract and open joints in the facade that affect the finish
- ✓ Work without evacuating the building — 100% exterior intervention — the ETICS system is worked entirely from the outside of the facade; tenants and owners do not have to leave the building during renovation
- ✓ Eliminates thermal bridges — the critical point of any renovation — continuous exterior insulation covers slabs, pillars, and window perimeters, the three points where interior insulation systems do not reach
- ✓ No loss of usable interior space — the insulation thickness goes to the exterior; in an 80 m² apartment, this can mean between 2 and 5 m² are preserved indoors
- ✓ ETAG 004 and UNE-EN 13499/13500 regulations — valid for projects with approval — the system complies with European reference standards for ETICS systems; necessary for projects with construction management and renovation files
How many boxes do I need for my facade?
Measure the surface area of the facade to be insulated (length × height of each section) and add the m². Add 5-10% for cuts and waste.
Example: 80 m² facade with 60 mm thickness (8 m²/box) → 80 ÷ 8 = 10 boxes + 10% waste = 11 boxes.
Complementary materials needed for the ETICS system
The Therm ETIX panel is the insulator of the system. To complete the installation, you also need:
- → ETICS adhesive mortar — fixes the panel to the existing facade
- → Mechanical fixing plug (nail or screw) — complementary anchoring mandatory according to CTE
- → Fiberglass mesh — reinforcement embedded in the base mortar
- → Facade finish — decorative mortar or silicone/acrylic render
