The Regulations Building regulations are in place to drive improvements in thermal efficiency, these regulations apply to new build, renovation or replacement work.
Thermal efficiency within these documents is expressed as a U-value.
Thermal board can be installed by either Dot and Dab or Dryliner method. The Dot and Dab method should only be used for walls that already include a cavity.
1. Starting from a window, door reveal or internal angle, mark the wall vertically with a chalk line for the row of dabs.
2. Using Siniat Universal Bonding Compound place a continuous ribbon 50mm at the top and bottom of the board.
3. Then place your dabs on the wall making sure that they are 250mm x 75mm in size and at 300mm centres.
4. A maximum spacing of 400mm horizontally should be used. A continuous ribbon should be placed around any plug sockets or light fittings.
5. Press the plasterboard in place against the dabs fitting the board tightly against the ceiling using a wedge or off cut at the base.
6. Tamp the board into place with the floor and ceiling chalk lines using a straight edge.
7. Use two Nailable Plugs to suit board depth, fitted through holes drilled in the board through the dab cavity and penetrating 25mm into masonry.(Tip: Wait until the dabs have set before fitting plugs to avoid moving or bending the board.)
8. Remove wedges when compound
1. Fix a dryliner track at 600mm centres to the floor and ceiling using suitable fixings. Allow for required cavity of at least 25mm.
2. If applying direct to concrete make sure that the surface is dry and a damp proof membrane.
3. Mark vertical lines at 600mm horizontal centres to fix the dryliner channels.
4. Start at the centre of the wall and position the dryliner brackets directly to the wall at a maximum 800mm vertical centres on the marked lines (at shoulder and waist height). Secure using suitable fixings. Fold out the toothed wings of each bracket to form legs.
5. Cut each dryliner channel 5mm shorter in height from the floor to the ceiling and place into the dryliner track.
6. Ensure channel is plumb and secure to each bracket using a Pan Head Self Tapping screw.
7. If installing kitchen units, install a GTEC fixing channel or timber reinforcement at the height the wall and floor units need to be secured.
8. Cut plasterboard 5mm shorter than the floor to ceiling height. Butt the board firmly against ceiling and fix with GTEC
Drywall Self Tapping screws at 300mm centres. Screws must be at least 10mm longer than the board thickness.
9. Butt the plasterboard edges lightly against each other and centre the edges over the channels.
One of the main areas of heat loss is through the roof. This installation guide will demonstrate how Thermal Board can be installed to meet required thermal performance. Installing the board and insulation at the same time using a laminated board is less time consuming and easier than separate installations.INSTALLATION1. Remove any existing plasterboard if present.
