StoVentec R

Seamless, rainscreen cladding facade with render
StoVentec R

Products and systems vary from location to location due to local building regulations and standards. We strongly advise you to make contact, your local expert will be happy to consult you on standards and approval.

System advantages

  • benefits in terms of building physics thanks to rear ventilation of the facade (humidity, sound and thermal protection)
  • sub-construction consisting of a wall bracket and vertical carrier profile (StoVentro Y): curved forms possible
  • almost unlimited creative possibilities using colours, textures, and materials
  • large seamless facade surfaces possible
  • unevenness can be levelled by means of an adjustable sub-construction
  • high reliability due to system solution with matched components

Thermal protection

  • mineral wool faced with nonwoven
  • system implementation also possible without insulation
  • sub-construction consisting of a wall bracket and carrier profile (StoVentro Y): large insulant thicknesses possible

Reaction to fire

  • class B1 in accordance with DIN 4102-1, limited combustibility
  • class A2-s1, d0 in accordance with EN 13501-1 with StoVentec Carrier Board A and a mineral or special organic coating build-up
  • Fire barriers may be required in accordance with national specifications.

Impact resistance

  • highly resistant to mechanical stress

Wind load

  • can be applied to all wind load areas by adapting the sub-construction spacings without visible impact

Sound insulation

  • improvement of up to 12 dB (A) in the sound reduction index

Other properties

  • very light, flexible carrier board made of expanded glass granulate with a low thermal expansion coefficient
  • special protection against algae and fungi with a double coat of paint
  • optional Lotus-Effect® Technology
  • optional Dryonic Technology for protection against microorganisms and for fastest possible drying
  • sub-construction consisting of a wall bracket and vertical carrier profile (StoVentro Y): resistant to earthquakes
  • 21886_2
  • 22364


Area of application

  • new and existing buildings, installation limits in accordance with national building regulations
  • especially suitable for fine surface textures
  • sub-construction consisting of a wall bracket and carrier profile (StoVentro Y): large system build-ups are possible, e.g. > 60 cm, suitable for the passivhaus standard with a certified sub-construction


  • masonry, e.g. brick, calcium silicate masonry units, cellular concrete, fair-faced masonry and masonry veneer
  • concrete, concrete slab construction
  • timber frame construction
  • lightweight construction


  • in timber frame construction with timber supporting battens
  • sub-construction consisting of a wall bracket and carrier profile (StoVentro Y): easily adjustable sub-construction made of a stainless steel and aluminium combination with the lowest thermal bridging coefficients


  • complete selection of detail solutions
  • simple and fast installation due to light panel weight

Creative possibilities

Design options

  • Acrylic renders, silicone resin renders, and renders with Lotus-Effect® Technology in stippled render texture, rilled render texture, or in free-style textured render
  • can be combined with StoDeco Facade Elements and a wide selection of facade coatings

Colour spectrum

  • tintable in accordance with the StoColor System
  • no limitation to the light reflectance value if using a cement-free build-up
