102.5mm Mannok insulated plasterboard, 2438 x 1200mm (8ft x 4ft) – a thermal board made from 90mm of rigid PIR insulation bonded to 12.5mm plasterboard, so you insulate and dry-line a wall in one go.
Key specifications
- Total thickness: 102.5mm (90mm PIR insulation + 12.5mm plasterboard)
- Board size: 2438 x 1200mm (8ft x 4ft)
- Coverage: 2.93 m² per board
- Board type: fibre-free PIR (polyisocyanurate) insulation laminated to 12.5mm plasterboard
- Thermal conductivity of PIR core (λ): 0.022 W/mK
- Reaction to fire: Euroclass B-s1,d0 (bonded to plasterboard, per Mannok's Declaration of Performance)
- Compressive strength: >150 kPa
- Certification: BBA certificate 07/4444, IAB certificate 05/0223
Uses
- Internal dry-lining of solid masonry and cavity walls, bonded with dot-and-dab adhesive plus secondary mechanical fixings
- Dry-lining onto timber battens
- Upgrading the thermal performance of walls in new builds and retrofit/renovation projects
Benefits
- Insulation and internal finish fitted in one operation, which saves time on site.
- High-performance PIR (0.022 W/mK) means less thickness for the same U-value, so you keep more room space.
- The plasterboard face gives a ready surface for finishing, and it improves the finish on old, uneven walls.
- Zero ozone depletion potential (ODP), low global warming potential (GWP) and an A+ rating against the BRE Green Guide.
FAQs
How do I fix insulated plasterboard?
On even, dry masonry walls, fix it with dot-and-dab drylining adhesive and 2 secondary mechanical fixings at mid-height. Alternatively, fix it to timber battens. Follow Mannok's installation guidance.
How many boards do I need?
Each board covers 2.93 m² (2.438 x 1.2m). Divide your wall area by the board coverage and round up, allowing extra for cuts around openings.
Which thickness do I need?
That depends on your wall build-up and target U-value. Thicker boards give better insulation. As a guide, Mannok quotes a U-value of about 0.21 W/m²K for 102.5mm board dot-and-dabbed onto a 215mm dense block wall. Mannok's U-value calculator and technical support can confirm the right board for Irish Building Regulations.
