Thermablok UK

Welcome to Thermablok Aerogel Ltd – Aerogel Insulation Technology

Thermablok® Aerogel is a revolutionary advancement in thermal technology offering the thinnest insulation available to prevent thermal and cold bridging. Classed as a Super Insulation, Aerogel has the highest insulation value of any known material with the lowest thermal conductivity value of any solid (0.015W/mK). Available in easy to use solutions for applications in all sectors including building and construction, refurbishments and energy efficiency retrofits. The thinnest and easiest solution to insulate hard to treat areas, especially where space is at a premium and where critical tolerances have to be achieved.

A thermal bridge (sometimes referred to as thermal bridging, a cold bridge or thermal bypass) describes a situation in a building where there is a direct connection between the inside and outside through one or more elements that are more thermally conductive than the rest of the building envelope.

All types of thermal bridging or cold bridging can be eliminated with our super thin, Super Insulation properties of Thermablok Aerogel to save valuable space. Within historic, period and listed buildings with architectural detailing, it offers a solution for an otherwise impossible area to insulate, with minimum effect on character.

Thermablok Aerogel works by breaking this thermal bridging link whilst being totally breathable, ensuring a healthy, durable working building with a natural ability to repel liquid (hydrophobicity) whilst allowing the passage and release of moisture vapour and does not rely on a vacuum or heavy molecular gases to insulate.

Thermablok Aerogel, being hydrophobic, is not affected by moisture or age, and provides major energy savings for the life of the building. A single 10mm thickness of Thermablok Aerogel Insulation Blanket increases the insulation factor of a standard solid wall construction by up to 67%.

  • We are so pleased with Thermablok, not just with the amazing product but with all the help and advice we received.
  • I think the material is nothing short of amazing. Thank you so much for all your assistance.
  • I just wanted to thank you for your very quick assistance and turnaround, not something that I experience often when it comes to purchasing building materials. I will make sure to recommend Thermablok to other people if the discussion turns to the need for high-quality insulation materials and great service..
  • The difference that your ThermaSlim Wall Insulation has made to our house and living experience is staggering. Thank you so much for everything from your advice to supply, we just can’t thank you enough. We just wish we had contacted you sooner and we would recommend you to everyone.
  • Just to let you know that the Thermablok Aerogel Blanket Insulation works brilliantly on the pizza oven too as have just started using now weather better!
    Happy to write a testimonial, but not quite sure what you are looking for?  I can say is that it is a standing joke in our family that I am so enthusiastic about the product! Apparently I am a bit boring about it!  Have just recommended you to a colleague of my husband who is putting in underfloor heating where height is a challenge.
  • I knew from the first moment of talking with your consultant that you were a company that were very different and that you knew your stuff. I always thought this was going to be difficult to understand as people just seem to make it difficult. This was not at all the case with you and we can’t thank you enough. Our installation is so thin we don’t notice a difference in wall depth but the difference in thermal performance is unbelievable. Thank you to you all for an enlightening, beneficial and warming experience.
