Kingspan K5 Insulation

Kingspan K5 Insulation is a Premium Performance Phenolic Rigid Thermoset Insulation Board suitable for applying to external masonry walls. Kooltherm K5 insulation is suitable for use behind both traditional and lightweight polymer modified render systems. Furthermore it is also suitable for dry cladding systems. These include tile hanging or external timber claddings and their artificial alternatives.

The insulation core has a glass tissue-based facing on both sides. These facings are bonded to the phenolic foam core during manufacture. The glass tissue gives and ideal face to render on once fitted with the appropriate render mesh. You can cut Kingspan Kooltherm K5 board either by using a fine toothed saw or with a sharp knife. If using a knife score one side the snap the board over a straight edge and then cut the facing on the other side.

A number of other products are required to complete this insulation system such as fixings and mesh for the render to key to.

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.

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

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.
