  • Ground floor insulation replacement.
  • Insulated base layer on top of consolidated hardcore.
  • Can be poured as an alternative to void former or high strength insulation (TLA250 or above).

Suitable for domestic, commercial and industrial projects energystore TLA® can be used as a direct replacement for insulation boards with no changes to membranes. Poured insulation leaves a continuous thermal layer with no gaps or breaks.


The energystore+ range dramatically reduces embodied carbon, using sustainable bio-fuel sources during manufacturing. energystore+ is independently assessed and certified by REDcert², Europe’s leading certification scheme for sustainable biofuel sources. energystore TLA®+ combines EPS beads coated in an innovative additive with cement to create a pourable insulation. Manufactured in accordance with BS EN 13163, BS EN 16025-1 and BS EN 16809-1.

Combining excellent thermal performance, enhanced compressive strength and an A2 fire rating for an exclusive insulation alternative.

The free-flowing and self-levelling properties result in faster and more efficient installation. U-values vary depending on grade and thickness, consult literature for details.

Features and benefits:

  • Enhanced air tightness.
  • More robust surface enabling thinner screeds.
  • Suitable to apply underfloor heating (UFH) directly on top.
  • Suitable for ground bearing and suspended floors.
  • Installed as a replacement for EPS/ PIR insulation.
  • Can be installed to a any depth from 50 mm.
  • Superior strength with very low density enabling weight reduction and reduced screed depth.
  • Zero waste on-site.
  • Reduced material usage.
  • Poured insulation means a continuous thermal layer with no gaps or breaks leading to superior in-life performance and enhanced Psi-Values.
  • BRE GreenGuide A+ rating
