Celotex PL 4000 Dry lining Boards, for Plaster Dab / Adhesive Bonding
Celotex PL 4000 Range Performance insulated PIR boards laminated to plasterboard
Internal dry–lining Celotex 4000 insulated plasterboard, is an insulated wallboard laminate ideal for use in plaster dab bonded dry–lining applications.
Benefits
Premium performance rigid phenolic insulation –
thermal conductivity 0.020 - 0.022 W/mK.
Insulation, dry-lining and vapour control in one board.
Negligible smoke obscuration.
Class O / low risk fire rating.
Little encroachment of room space.
Energy saving – allows quick response heating.
Applications
Suitable for use with all cavity masonry wall constructions and some solid walls and, as well as timber frame walls. The boards are handled and fixed as with standard plaster board methods.
Celotex PL 4000 boards . Technical spec. Performance ( r value compared with K17)
What is surprising is that Celotex a cheaper board compares very favourably with Kingspan in terms of R value ( thermal resistance)

Cutting
Cutting should be carried out either by using a fine toothed saw, or by scoring with a sharp knife, snapping the board over a straight edge and then cutting the facing on the other side.
Ensure accurate trimming to achieve close butting joints and continuity of insulation.
