Celotex Insulated Plasterboard Mechanical Fixing Guide

Before you begin:

  • Ensure the wall is sound, secure, free from any contaminants and dry.
  • When cutting the insulated plasterboard, it should be carried out by using a fine toothed saw, or by scoring with a sharp knife and then snapping the board over a straight edge and then proceeding to cut the facing on the other side.
  • Ensure accurate trimming to achieve close joints and continuous insulation.

Step 1:
Fix timber battens at the floor and ceiling around the room’s perimeter. Then fix further battens to the wall and around any openings or surfaces. Fix each batten approximately 75mm from its end and no more than 600mm horizontal centres.
Each batten should have a minimum depth of 25mm and width of 47mm and backed with a strip of damp proof course.

Step 2:
The installation should start from an internal corner, a window or door reveal.
Insulated plasterboard sheets should always lap the timber battens at the sheet joints. Note the timber noggins may be required where sheets of insulated plasterboard are unsupported.
Ensure each sheet is lightly butted with fixings located no less than 10mm from the bound edges of the sheet. Cut the insulated plasterboard approximately 5mm short of the floor to ceiling height.

Step 3:
Fix the sheet with either drywall screws at 300mm centres or large headed galvanised clout nails at 150mm centres. Fixing should be long enough to allow a minimum penetration into the timber batten or frame.
Drive all fixings straight, with heads embedded just below the surface of the plasterboard.
To finish seal the perimeter of the insulated plasterboard with a flexible sealant or equivalent.
Regardless of the method used, additional consideration should also be given for the fixings of cupboards and radiators etc.
