Frente Forjado

Solution for thermal bridges

Grafipol Frente Forjado is a black rigid expanded polystyrene (EPS) foam with low thermal insulation, whose raw material particularly increases thermal insulation to equal the density of conventional EPS.

Its excellent thermal characteristics and specific design make it specially recommended to insulate reinforced beams of reinforced concrete structures and intermediate insulation, thereby removing thermal bridges in the façade of the slab edge.

Available for two possible uses, based on the insulation coating:

  • To coat with ceramic gravel, ensuring continuity with the brick wall: flat surface panel with a thickness of 20 mm.
  • To apply cover with mortar and reinforcement mesh: mechanised surface panel in the form of dovetail of a thickness of 30 mm.

It may be placed before the concrete, fixing the formwork (riser) or mechanically fixing the slab edge once the formwork of the structure has been removed.

CONSTRUCTION DETAILS

Option 1

Use in slab edge of ceramic gravel before the insulation.

  1. Façade sealing
  2. Ceramic gravel
  3. Thermal insulation: GRAFIPOL FRENTE DE FORJADO (λ = 0,032 W/mK, smooth surface, e=20mm) placed before the concrete, fixed to formwork riser, embedded to the façade’s thickness
  4. Reinforced concrete slab edge
  5. Continuous exterior coating: monolayer mortar

Option 2

Used in slab edge with direct mortar cover over the insulation.
