Speedline insulated plasterboards are designed to be installed within a property to improve thermal conductivity. Speedline insulated plasterboards are made up of a fibre-free rigid polyisocyanurate (PIR) core fixed to a 12.5mm plasterboard during the manufacturing process. This 2-in-1 product combines thermal insulation and dry-lining solutions into a single board. The boards are manufactured with Zero Ozone Depletion Potential (ODP) and Zero Global Warming potential (GWP), free from CFC and HCFC.

Speedline Insulated Plasterboards are available in sizes 1200mm by 2400mm with sizes ranging from 37.5mm to 72.5mm. This is made up of a (PIR) foam board and 12.5mm plasterboard for example, a 40mm board attached to 12.5mm plasterboard will amount to a 52.5mm insulated plasterboard. This board provides a thermal conductivity of just 0.022W/mK. The boards are lightweight and easy to cut, handle, and install. A fine-toothed saw is recommended to cut insulated plasterboards. A plank of wood or ruler can also be used to create a cutting guide and hold the board in place.

Key Features:

  • Simple solution to upgrading walls and roofs
  • Cost and time effective
  • Enables thermal insulation and internal finish to be applied in one operation
  • Ideal for both new build and renovation projects
  • Multi-purpose applications
  • Green Guide Rating A+
  • Long lasting and durable
  • Meet or upgrade current building regulations
  • Avoid the risk of condensation as boards provide both vapour resistance and remove thermal bridging
  • Speedline Thermal Laminates can be finished by either ‘Taping & Jointing’ or gypsum skim plaster

Insulated plasterboards can be applied to the interior walls within a property. The two in one insulated plasterboard insulates and drylines walls in one method which can make the insulation process quicker as plasterboard will not need to be applied to the insulation boards after they are installed. Once the insulated plasterboards have been installed the next step of applying plaster can be applied. When installed correctly the insulated plasterboard will have a lifespan that last for as long as the building does.

Applications include both new builds, refurbishments, and upgrading the thermal performance of existing building elements. This product can be applied with mechanically fixing or dot and dab adhesive dry lining applications. This can be applied to new or existing walls

Speedline Insulated Plasterboards can be installed in a range of methods. These methods include:

  • Solid Masonry Walls – Mechanical fix onto Timber Battens
  • Solid Masonry Walls – Mechanical fix onto Speedline Wall Liner System
  • Masonry Cavity Wall
  • Pitched Roof Application
  • Flat Roof Application

Manufactured in accordance with:

  • Fire Performance Class B s1,d0
  • Manufactured in accordance with ISO 14001: 2004

How to install Speedline insulated plasterboard using mechanical fixings:

Ensure walls are structurally sound and are clean dry and free from protrusions. Remove any fittings and strip any paint or wallpaper. Place dustsheets where needed. Work should be carried out in well ventilate condition and protective gear such as eye goggles, protective clothing, gloves, and face masks is recommended.

Measure the requirements and cut the boards accordingly using a fine-toothed saw allowing 5mm off from the floor to ceiling height. Take care when handling insulated plasterboard as wet or damaged boards should not be used. Before fitting ensure any gaps around the perimeter of the wall openings or penetrations are sealed with a flexible sealant.

Each wall to be fitted with Speedline will need battening with treated timber or a proprietary metal wall lining system. Measure or mark the wall to indicate the batten positions. Include all wall edges, opening and services. Before fixing, remember to attach 100mm strips of DPC to the back of each timber batten.

Vertical battens should be placed at a maximum of 600mm centres. Horizontal battens at both top and bottom and around openings. To fix, drill through the timber into wall and secure in place using woodscrews and wall plugs or all in one hammer fittings. Timbers can be packed out to ensure a level surface. Fixings should penetrate a minimum of 45mm into the is existing masonry and should be no more that 600mm apart and 75mm in from the end of each batten

Place the insulated plasterboards into position ensuring all adjoining boards are tightly butted and meet the centre lines of each batten. All joints should be staggered or break bonded. Secure the boards to the timber battens using dry wall screws at 300mm centres and 200mm centres around openings and external corners.

Fixings should penetrate at least 25mm into the timber or penetrate at least 10mm into metal studding. Fixings should be no less than 10mm in from the edge of the board. Screw heads should finish just below the surface level of the plasterboard and should not penetrate the masonry.

Seal floor and ceiling gaps with PU filler foam and then flexible sealant or equivalent. Apply the sealant around any further joints or breaks. Then either tape and joint boards or skim walls as appropriate.
