kooltherm insulated plasterboard

Kooltherm Insulated Plasterboard

Kingspan Kooltherm insulated plasterboard range consists of K118 which is the paper backed board. This is designed for dot and dab applications using drywall adhesive. It is advised to use a few mechanical fixings on these boards at the same time as fixing with drywall adhesive.

This insulated wallboard replaces the Kooltherm K17 and Kooltherm K18 insulated plasterboards and has a higher thermal conductivity. Approximate coverage of the drywall adhesive is three boards per bag. This Kooltherm insulated plasterboard has a Euroclass B-s1,d0 fire rating and a superb low thermal conductivity as low as 0.022W/m K. Kingspan Kooltherm K118 laminated wallboard is the mechanical fixed equivalent of the Kingspan K17. Both of these boards are a modified resin insulation board laminated to 12.5 mm tapered edge standard plasterboard.

Costs of Kooltherm insulated plasterboard

Although it can work out more expensive than buying the separate plasterboard and insulation sheets it can save labour costs by being a single fix product enabling a far more quicker installation. I guess it would depend on whether or not you are fixing the product yourself or employing a builder to do it for you. Whether or not its financially better to use this all in one or install separately. Importantly it must be noted that the backing on these insulation boards are phenolic foam. This being a far superior thermal insulation to polystyrene and PIR insulation boards which can also be found laminated to plasterboard.

If you need to buy Kingspan Kooltherm K17 or K18 then please do not hesitate to call our friendly sales team. NOTE : these products have been discontinued and replaced with Kingspan Kooltherm K118.

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.
