Application

The system was particularly formulated to be used in applications with a high requirement for compression resistance (floors, terraces, roofs, etc).

Suitable substrates include:

  • Concrete.
  • Brick.
  • Wood.
  • Steel.

Description

The Elastospray 1623/14/45 system has been developed as a sprayed (in-situ) polyurethane (PU) thermal insulation.

Features and benefits:

  • Excellent properties as an insulation material.
  • Excellent compression strength values.
  • Suitable for insulating large areas, including irregularly shaped surfaces such as undulated roofs.
  • Reaction to fire (to EN 13501-1): Class E.
  • Good values of compressive creep.
  • Excellent adhesion to the substrate. The spray foam bonds to most surfaces without the need for glues or mechanical fasteners.
  • Does not contain hydrochlorofluorocarbons (HCFCs).
  • CE marked, and manufactured in accordance with EN 14315-1: 2013.

Applications:

The system was particularly formulated to be used in applications with a high requirement for compression resistance (floors, terraces, roofs, etc).

Suitable substrates include:

  • Concrete.
  • Brick.
  • Wood.
  • Steel.

Product Options

Thickness:

Dependent on application, consult the manufacturer for information. The thickness of each applied layer should be between 1–4 cm. In order to maintain adequate dimensional stability, it is not recommended to apply thicker layers. See manufacturer's literature for performance charts related to different thicknesses.
