Military (MIL-C-882 and MIL-E-5272A) and government (AASHTO 18.4.9) infrastructure grade thermal break and bearing pad.

Features and benefits:

  • Provides an economical and effective solution to Part L of the Building Regulations.
  • Can be optimized for vibration and shock isolation in structural applications.
  • Deflection and rotation of the pad can be tailored to suit the application (allows for rotations up to 0.02 radians under high pressure).
  • Designed for medium loads, with even distribution of the load between two structural elements.
  • Minimal creep.
  • Contains rot and mildew inhibitors and anti-oxidants.
  • Accommodates non-parallel, load bearing surfaces.
  • Pads will have uniform thickness.


Primarily for connections where shock or absorption is of concern. Typical applications include:

  • Steel-to-concrete applications.
  • Concrete and precast joints.
  • Heavy industry and pipelines.
  • Bridges, rails, tunnels and other infrastructure.
  • Roof mounted structures and exterior HVAC units.

Not for use with moment connections.
