Facade (EIFS)
Complete EIFS system material calculation
How the calculation works
Enter the facade area and EPS board thickness. Using consumption per m² for each ETICS layer (boards, anchors, mesh, adhesive, primer, finish, profiles), the calculator works out total quantities and the number of packs.
Formula and assumptions
Quantity = area × consumption per m² for each material; packs = quantity ÷ pack size, rounded up. Example consumption values in the app: EPS 1.05 m²/m², anchors 6 pcs/m² (boxes of 100), mesh adhesive 5.5 kg/m² (25 kg bags). These are indicative – follow the manufacturer's system.
Worked example
Facade 100 m²: EPS 1.05 × 100 = 105 m². Anchors 6 × 100 = 600 pcs → 6 boxes. Mesh adhesive 5.5 × 100 = 550 kg → 22 bags × 25 kg.
What affects real consumption
- Wall unevenness and cutting boards around openings.
- Higher anchor density near edges and at height (wind load).
- Exact consumption and build-up are set by the ETICS manufacturer.
Frequently asked questions
What is ETICS (external thermal insulation)?
A facade insulation system: adhesive, insulation boards, mechanical fixing, a reinforced layer with mesh, and a finishing render and paint.
Are the calculated quantities a design?
No – they are an estimate for ordering; the installation and number of anchors must be confirmed against the project and the system manufacturer's instructions.
Does the calculator work out the facade price?
No, it calculates material quantities (EPS boards, adhesive, mesh, anchors, render). Multiply them by your supplier's prices to get a cost; the calculator does not estimate price because it depends on the product, region and labour.
