DANOLOSA NOX 95 is an insulating slab consisting of porous concrete, which acts as a mechanical protection over an extruded polystyrene base, resulting in a durable and practical insulated surface. With NOx reducing photocatalytic effect treatment.


  • Technical roofs on supports (plots).
  • Insulating and filtering slab for accessible roofs.
  • Technical walkways on non-accessible roofs finished in gravel.
  • Renovation and transformation of non-accessible roofs.
  • Support surface for equipment on non-trafficable roofs and installations in general.

Advantages & Benefits

  • Lightens the weight of the tyre compared to other types of heavy protections.
  • High resistance to compression, allows people to transit.
  • Adds thermal insulation and walkable paving to the roof.
  • High filtering capacity, allows installation and transit in adverse weather conditions.
  • Paving joints are not needed thanks to the 1-2 mm “reduction” of the porous concrete layer with respect to the XPS insulating base.
  • Allows for the placement of benches and supports to place equipment and facilities.
  • Protects waterproofing.
  • Photocatalytic purification of NOx gases > 8% (Class 3).
  • It can be disassembled, facilitating access to the waterproofing.
  • Simple installation.

Instruction for Use

Preparation of the support:
Once the waterproofing is done, the roof should be smooth, uniform and clean. Danolosa application:
  • It is applied without any gripping material, deposited with care, preferably over a geotextile antipunching layer covering the waterproofing or directly on it, lying on the insulation face.
  • Slabs will be placed without any expansion joint.
  • On hipper ends and valleys the slab should be accordingly cut using a water-cooled low r.p.m. radial machine.
  • A small space (3-5 mm) must exist, to allow dilatations coming from, for example, skylights, etc…
  • It should be carried on pallets.
    • Not considered as dangerous goods for transport.

Indications and Important Recommendations

  • A separating layer type DANOFELT® PY 300 must be placed between the PVC waterproofing and the tile.
  • It is not necessary to use filler in the joints.
  • Do not use hammers to fit or level the parts.
  • Its use on plots is restricted to supports with a square head of at least 200 mm.
  • For the cutting of the DANOLOSA, it is recommended to use a water-cooled low r.p.m. radial machine, type DU-200-L.
  • The apparition of portlantita efflorescences on porous concrete, characterized by changing the colour of the tile, does not mean the decline of its performance.
  • Variations in tone in the raw materials of porous concrete may also vary the tone between tiles of the same colour.

Handling, storage and preservation

  • The cutting machines must be in a ventilated room.
  • Keep away from flames and sources of heat.
  • Keep in ventilated areas, preferably in premises with fire prevention systems, as remnants of ethanol (traces) may be released in the production process.
  • Goods not considered hazardous.
  • It must be transported on pallets.
