Insulation

EPS, XPS, mineral wool — boards by thickness, adhesive and dowels.

Surface area

m²

Application

The material set depends on the application: adhesive and dowels are facade-only.

Material

Insulation thickness

Building height

Taller building — more dowels for wind load.

Finish (mesh + render)

Base coat with mesh, primer and decorative render.

Starter profile

Base starter profile along the bottom — length in running m (0 to skip).

Corner beads

Corner bead with mesh — length of all external corners, running m.

Reserve

How much material to take beyond the calculation for trimming and defects. Usually 5–15%.

Boards per pack

pcs

To convert boards into packs (0 to skip).

Pack price

MDL

Rough cost = price × number of packs.

Boards needed

132boards

Structure volume: 6 m³ (thickness 50 mm)

Boards volume: 6.6 m³ · reserve 0.6 m³

Dowels: 720 pcs · length 100 mm

Recommendation

Insulation: facade EPS (PPS-16F) · ≥ 16 kg/m³

For a rendered facade — facade EPS or dense mineral wool (non-combustible).

How the figure is calculatedRendered facade. EPS foam 50 mm: 120 m² ÷ 1 m² (1000×1000) + 10% = 132 boards. Volume 6 m³.

Lay the boards with staggered joints. Fix dowels after the adhesive sets; place them denser at corners and edges. Wrap the mesh around corners and embed it in the fresh base coat.
