Kingspan K3 Insulation is a Kingspan phenolic floor insulation board.

This Kingspan Kooltherm K3 is a premium performance rigid thermoset phenolic insulation board for use under screed finished floors and suspended timber ground floors.

Importantly Kingspan K3 insulation is available in a range of thicknesses from 25mm up to 150mm.Kooltherm K3 offers considerable advantages over other floor insulations as it offers both a higher degree of insulation properties along with a higher compressive strength. This when compared to standard PIR type insulation boards.

Kingspan Kooltherm can have thermal conductivities as low as 0.020 W/m K furthermore the board is Class 0 Fire rated and is resistant to the passage of water vapour. The boards are manufactured with a blowing agent that has zero Ozone depletion and low Global warming potential. So has very little impact on the environment.

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 ? :-)

Very happy with the service we received. Fantastic product at a fantastic price. Cant recommend Jason and the team highly enough. Ordered during Covid-19 when everything was slightly crazy and delayed and Jason called and said they had a lorry in our area so could deliver the very next day! Thank you guys for 5 star service, will be back in the future . All the best, Lacey. Travellers Finds Ltd

Lacey Griffiths, Travellers Finds Ltd

Excellent company, Jason gave us a really good price and the items were delivered 2 days later much quicker than anyone else could offer. even the delivery driver was incredibly helpful, honestly can’t fault them Jacqui

Jacqueline Jelley,

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.
