    Product Description

    Gyproc ThermaLine PLUS Wallboard insulated plasterboard - 35mm

    Gyproc ThermaLine PLUS Wallboard

    Gyproc WallBoard factory-bonded to an extruded polystyrene insulant that is both CFC and HCFC-free - meaning zero ODP (Ozone Depletion Potential). The closed cell structure of the foam provides integral vapour control. Gyproc ThermaLine plus consists of an aerated gypsum core encased in, and firmly bonded to, strong paper liners. The extruded polystyrene insulant is then further bonded to the finished plasterboard. Gyproc ThermaLine plus is a plasterboard that is suitable for drylining internal surfaces. This plasterboard is one of the products within our plasterboard range that is certified to BES 6001 achieving a rating of ‘Excellent’.

    The closed cell structure of the foam provides integral vapour control. Designed to be used in both refurbishment and new build for walls, ceilings and reveals where a medium level of thermal insulation is required to reduce heat loss from buildings.

    Suitable for new buildings and for upgrading existing buildings when mid to high thermal performance is required.

    Board performance - Fire protection
    Plasterboard linings provide good fire protection owing to the unique behaviour of the non-combustible gypsum core when subjected to high temperatures. For the purposes of Building Regulations Approved Document B, plasterboard is designated a ‘material of limited combustibility’. The surface of Gyproc ThermaLine plus is designated Class 0 (for the purposes of the Building Regulations).

    Effect of temperature
    Gyproc ThermaLine plus is unsuitable for use in areas subject to continuously damp or humid conditions, i.e. above 70% RH, and must not be used to isolate dampness. Plasterboards are not
    suitable for use in service temperatures above 49°C, but can be subjected to freezing conditions without risk of damage.

    Effect of condensation
    The thermal insulation and ventilation requirements of the Building Regulations aim to reduce the risk of condensation and mould growth in new buildings. However, designers should take care to eliminate all
    possibility of problems caused by condensation, particularly in refurbishment projects. For further
    information, please refer to the White Book, available to download from

    Application and installation - Cutting
    This product may be cut using a plasterboard saw. Holes for switch or socket boxes should be cut out before the boards
    are fixed using a utility saw or sharp knife. When cutting boards, power and hand tools should be used with care and in accordance with the manufacturers’ recommendations. Power
    tools should only be used by people who have been instructed and trained to use them safely. Appropriate personal protective equipment should be used.

    Fix boards with decorative side out to receive joint treatment or a skim plaster finish. Lightly butt boards together. Never force boards into position. Install fixings not closer than 13mm
    from cut edges and 10mm from bound edges. Position cut edges to internal angles whenever possible, removing paper burrs with fine sandpaper. Stagger horizontal and vertical board joints between layers by a minimum of 600mm. Locate boards to a the centre line of framing where this supports board edges or ends.

    Gyproc jointing materials produce durable joint reinforcement and a smooth, continuous, crack-resistant surface ready for
    priming and final decoration. A number of jointing specifications are available to suit the board type, method of application, and site preference.

    After the joint treatment has dried, decoration, including any decorator’s preparatory work, should follow with the minimum delay.
