Applications SDPspray RDP 2136-M

The SDPspray RDP 2136-M Rigid Spray Foam system is a thermal insulation process for agricultural buildings, attics, and crawl spaces based on in situ sprayed polyurethane foam. After expansion, it forms a fire-retardant rigid insulation of CCC Class 4 with a density range between 35 g/L and 40 g/L.

The SDPspray RDP 2136-M Rigid Spray Foam system is highly regarded for:

  • Its excellent lambda value
  • Its self-extinguishing properties
  • Its excellent smoothing power
  • Its excellent adhesion to all substrates
  • Its ease of application (Iso-viscosity polyol / Isocyanate)
  • Its excellent dimensional stability
  • Its excellent economic yield


The SDPspray RDP 2136 M Rigid Spray Foam system is a two-component product designed to be applied via a mobile in situ injection machine.

The Polyol is a composition based on polyether and polyester polyols, catalysts, and 100% reactive stabilizers, along with latest-generation blowing agents (zero ODP and low GWP). The flame retardants used are non-halogenated.

The Isocyanate is an MDI.
