kingspan kooltherm k108 cavity insulation

Kingspan K108 Insulation

Kingspans K108 Insulation is a premium performance cavity wall insulation for use in a partial cavity wall insulation construction. Kooltherm K108 insulation has a super low thermal conductivity of 0.019 W/m-K. Having a higher grade of insulation in the cavity allows for a thinner insulation to be used on the interior of the construction. Therefore giving a greater available living space. Being a partial fill cavity insulation it leaves a clear cavity space and resists moisture penetration. Kingspan Kooltherm K108 insulation is a lightweight easy to handle insulation material and is easy to install. This high performance board when used at 120mm thickness and with aerated blocks can achieve ‘U’ Values as low as 0.12 W/m-K. Overall a superb choice of cavity wall insulation when a high spec is required.

Most importantly to note is that this Kingspan phenolic cavity wall insulation is manufactured in a wide range of thicknesses. Standard cavity sizes are accommodated from kingspans standard stock range such as 100mm , 110mm , 125mm and 150mm. It must be noted other sizes are also available but must be made to order and in quite large quantities.

Purchsed our floor and wall insulation from this company, they are very helpful and went through the options available to me. after searching about the total price was the best i had so i gave them the order. Deliervy was made in 2 days and everything was fine. I will use them again for the next part of my building project.

James Kergan, JK Building services

As a small building company we find that BMD will equal or beat our trade depot plus we get free delivery too !!, Also we can get everything in one order and being able to talk to an actual person rather than clicking on a website means we get the service we want. saves time and money whats not to like ? :-)

After days of trying to order some Rockwool from suppliers who never got back to me or quoted silly prices, my enquiry to BMD was answered in minutes politely and with clear knowledge of the products and delivery arranged on the phone all at a great price. Top marks for A1 service and product knowledge.
