Product Spotlight: ThermaBead Cavity Wall Insulation

The winter season always brings with it an inevitable spike in the energy bill. According to the Energy Saving Trust, about a third of all the heat lost in an uninsulated home escapes through the walls. As a result, people living in such properties will be spending more to keep themselves warm and in addition, will also increase their carbon footprint.

Does my house have a cavity wall?

Properties built after the 1930’s tend to have two brick walls. The gap between the inner and outer walls is known as a “cavity”. If the space of the cavity is at least 40mm between bricks and held together with wall ties then cavity insulation is suitable and recommended.




Arktek aims to provide the best quality of service to its customers and has a strong commitment to maintaining its quality standards. This is why we are offering the ThermaBead cavity wall insulation system which has been identified as having several advantages over standard fibre insulation.

Benefits of ThermaBead:

  1. Lower U value: Heat lost through materials is measured as a U value. Depending on the property and the length of the cavity, installing the ThermaBead product can improve the U value by approximately 70%, making it up to 20% more efficient than standard fibre insulation.
  2. Ease of installation: Using all weather specialist equipment, installation can be done in one day. Due to the unique nature of the fast flowing beads, the process requires fewer and smaller drill holes than other insulation systems and ensures all possible areas are filled.
  3. Flowability: The special flow properties of the beads allow the system to achieve a superior cavity fill, ensuring no cold spots and addressing settlement issues identified in other materials.
  4. Moisture Dissipation: Unlike other fibrous materials the special beads used to insulate the wall do not possess the same absorption properties and will not allow water to accumulate allowing a safe dispersion of moisture.

Considering the above points, our team has reached the conclusion that ThermaBead offers an easier and more effective solution to making your home warmer and more environmentally friendly. In addition to being a BBA(British Board of Agreement) and KIWA approved product, all work comes with a 25 year Insurance Backed Guarantee through GDGC. With potential savings of up to £250 per year this is the ideal solution for your home in regards to cavity wall insulation!
