Isocheck Isoliner Thermal Laminates

Thermal laminate products, featuring plasterboards bonded to high performance rigid foam insulation, have become an effective means of helping achieve energy efficient building fabric solutions in both new build and refurbishment projects.

 

Modern construction is centred around achieving highly insulated, airtight building fabric, complemented by appropriate ventilation to maintain a healthy supply of fresh air.

 

Restricting the flow of heat through building materials, and the leakage of warm air through gaps in the structure, reduces the need to continually heat the internal environment – with a corresponding reduction in energy use and fuel bills.

 

Isoliner Laminate Board provides thermal insulation and a ready-to-finish internal lining in one product. It allows additional insulation to be installed internally, in an efficient continuous layer, to help meet the U-value targets required by current building regulations, without the need to fix plasterboards separately.

Designed to supplement insulation positioned within new and existing structures, Isoliner is particularly suited to refurbishment projects where external insulation, or invasive work to existing fabric, is undesirable. It can be used to line walls, and ceilings of pitched roofs and certain flat roofs.

 

Isoliner Laminate Board features a plasterboard with greater acoustic mass than the plasterboards used in many other thermal laminate products. For applications with a Sound Reduction Index (Rw) requirement, the use of Isoliner Laminate Board may assist in reducing airborne sound transmission, especially in lightweight structures, subject to the method of fixing and the other components in the construction.

 

Isoliner Laminate Board is also:

  • Suitable for both direct bonding (dot and dab) and mechanical fastening.
  • Easy to handle and install.
  • For use on solid walls, cavity walls, timber frame walls, beneath rafters in pitched roofing and beneath joists in flat roofing.
  • Ideal for new build, conversions and refurbishments projects.

Masonry walls: direct bonding (‘dot & dab’)

Isoliner Laminate Boards can be adhered to masonry substrates using proprietary gypsum-based adhesive, in accordance with manufacturer’s instructions. The adhesive should be supplemented with a limited number of suitable mechanical fixings to guard against early collapse in the event of a fire. To achieve an airtight seal at perimeter joint locations, use Isomass Fire Rated Acoustic Sealant.

Mechanical fixing to timber battens

Secure timber battens to the supporting masonry wall at maximum 600mm centres. Fix Isoliner Laminate Boards to the battens using drywall screws, with a minimum of 25mm penetration into the timber. The screw head should sit flush with the face of the plasterboard. To achieve an airtight seal at perimeter joint locations, use Isomass Fire Rated Acoustic Sealant.

Mechanical fixing to Isoliner Wall Systems

Install the Isoliner System in accordance with the installation instructions, secured to the supporting masonry wall and with vertical studs at 400mm or 600mm centres. Fix Isoliner Laminate Boards to the frame system frame using drywall screws, with a minimum of 25mm penetration into the timber. The screw head should sit flush with the face of the plasterboard. To achieve an airtight seal at perimeter joint locations, use Isomass Fire Rated Acoustic Sealant.

Ceiling applications: pitched roof and cold flat roofs

Spacing of supporting rafters and joists should not exceed 600mm. Fix Isoliner Laminate Boards to the structural timbers using drywall screws, with a minimum of 25mm penetration into the timber. The screw head should sit flush with the face of the plasterboard. To achieve an airtight seal at perimeter joint locations, use Isomass Fire Rated Acoustic Sealant.

 

Linear thermal bridging – window and door reveals

  • Achieving a well-insulated building fabric and avoiding paths (called thermal bridges) for heat to bypass layers of insulation means attention to detail. In particular, it means careful treatment of the junctions between elements, such as openings in the fabric for doors and windows.
  • Doors and windows have their own thermal performance. That performance may be relatively good in a new-build project, or where replacements have been installed as part of a refurbishment.
  • For the performance to be effective, however, they have to be part of the insulation envelope – and where a laminate board is installed internally, it is unlikely they will be fixed so far back in the opening.
  • Continuing the laminate board into the ‘reveals’ of window and door openings is therefore necessary to maintain the continuity of the insulation envelope. Current industry guidance, in the form of Accredited Construction Details (ACDs), recommends that insulation used in reveals should provide a minimum thermal resistance of 0.34m2K/W, which is exceeded when using a 37.5mm Isoliner Laminate Board.
  • Failing to treat thermal bridges such as window and door reveals creates ‘cold spots’ where the risk of condensation occurring increases. As warm, moist air comes into contact with the locally cold surface, the temperature of the air drops and deposits the excess moisture as condensation.
