    Product Details
    The Facings
    Kingspan Thermawall® TW55 is faced on both sides with a low emissivity composite foil, autohesively bonded to the insulation core during manufacture. This reflective, low emissivity surface improves the thermal resistance of any unventilated cavity adjacent to the board.

    The Core
    The core of Kingspan Thermawall® TW55 is manufactured with Nilflam® technology, a high performance fibre–free rigid thermoset polyisocyanurate (PIR) insulant manufactured with a blowing agent that has zero Ozone Depletion Potential (ODP) and low Global Warming Potential (GWP).

    Sustainability & Responsibility
    Kingspan Insulation has a long–term commitment to sustainability and responsibility: as a manufacturer and supplier of insulation products; as an employer; as a substantial landholder; and as a key member of its neighbouring communities.

    NBS Specifications
    Details also available in NBS Plus. NBS users should refer to clause(s): F30 155, P10 210, K11 495 (Standard and Intermediate) F30 12, P10 40 (Minor Works).

    Water Vapour Control / Condensation
    Condensation can be controlled, in constructions containing Kingspan Thermawall® TW55, by ensuring there is a layer of high vapour resistance on the warm side of the insulation layer. If required, the vapour resistance of the wall lining can be increased by the use of a vapour check plasterboard*, the use of Kingspan Kooltherm® K118 Insulated Plasterboard, which contains an integral vapour control layer*, the use of a layer of polythene sheeting*, or by the application of two coats of Gyproc Drywall Sealer.

    Fire Stops
    Current Building Regulations / Standards should be considered with regard to the requirements for, and provision of, fire stops

    Lightning Protection
    Building designers should give consideration to the requirements of BS / I.S. EN 62305: 2011 (Protection against lightning).

    Cutting should be carried out either by using a fine toothed saw, or by scoring with a sharp knife, snapping the board over a straight edge and then cutting the facing on the other side.
    Ensure accurate trimming to achieve close butting joints and continuity of insulation.
