Marmox (UK) Ltd

Load-bearing, thermal insulation block that eliminates cold bridging at the wall/ floor junction.

Jump to:
+44 (0)1634 835290 www.marmox.co.uk
Application

Designed to be placed at the base of a masonry or timber framed wall to address the thermal bridge.

Description

With a compressive strength of 9 N/mm², Thermoblock can be used at the base of load-bearing walls, either replacing the bottom row of aircrete blocks, beneath the floor flab or beneath a timber frame’s sole plate to stop the cold bridge from occurring.

Features and benefits:

  • Reduces heat loss at the base of walls.
  • Guarantees to provide a significant reduction in the Y value entered into the SAP/SBEM/DEAP energy assessment spreadsheet.
  • 9 N/mm² compressive strength meets UK and Irish building regulations enabling it be used in supporting walls.
  • Impermeable to water, and can be used in damp conditions without any loss to the insulating properties.
  • Suitable to form the base of walls comprising brick, block or wooden frame.
  • Suitable to form the base layer beneath timber or steel frame walls.
  • BRE certified.

Width:

It is important to ensure that walls are wider than the width of the Thermoblocks that they are placed upon. Consult manufacturer for details.

Marmox sealant is recommended for sealing the ends of the Thermoblocks together to prevent moisture intake and to ensure building air tightness.

For fitting instructions onto different types of substrate, consult manufacturer's literature.

Application:

Designed to be placed at the base of a masonry or timber framed wall to address the thermal bridge.
