  • Cavity wall insulation

    10Verified Review

    We had cavity wall insulation put in by Multi therm and noticed the difference after the first night. The house is so much warmer now. Martin and Neil were excellent in their communication with us throughout the job and worked very professionally. Would highly recommend this firm if you want your house warmer

Company info

Welcome to our Checkatrade page and thank you for taking the time to look into our details. 

We are a small company based in South Yorkshire offering superior bonded poly bead cavity wall insulation.

We offer cavity wall insulation for many purposes and more often than not we can provide a solution for non-standard jobs where others cannot cater for.

We specialise in installing brick and stone properties.

Our compressed air system of bonded polybead is injected under pressure to ensure a tightly compacted fill within the cavity.

Our main aspects of work are:

  • Stone wall insulation - 'Virtually No Drill System' - We can fill walls without showing any drill holes - (contact us for more details).
  • New build cavity insulation - Insulated internally before plastering.
  • Narrow cavity wall insulation (Brick or stone)
  • Partial fill cavity wall insulation (poly blocks on inner wall still leaving a cavity)
  • Cavity wall insulation extraction (removes faulty or problematic insulation)
  • Difficult access jobs (conservatories, river sides or multi-storey)
  • Cavity wall insulation extraction - Removal of problematic insulation
  • ( Cavity can be left empty or re-insulated properly.

For any queries or questions please call us today or email us 

We look forward to working with you in the future !
