What is 29.5mm plasterboard?

29.5mm boards in this collection are slim, high-performance wall linings designed to improve thermal comfort while keeping the build-up as thin as possible. Typically, they combine a standard gypsum plasterboard face with a factory-bonded insulation layer to reach an overall thickness of ~29.5mm. You get the finish of a plasterboard (ready for tape, joint and skim) with the thermal boost of an insulated lining, ideal for refurbishments where every millimetre matters.

Benefits of 29.5mm boards

• Space-saving performance: Noticeable thermal improvement without stealing room space.
• Warmer walls, fewer cold spots: Helps reduce heat loss and surface condensation risk.
• Neat, fast finish: Fix like a board, then tape & joint for a smooth decorating surface.
• Moisture control (product-dependent): Many options include a foil facer that also acts as a vapour control layer when seams are sealed correctly.
• Refurb-friendly: Great for occupied homes, minimal disruption, no wet trades beyond skim.

Applications of 29.5mm boards

• Internal wall lining of solid masonry or older cavity walls during upgrades.
• Window and door reveals to limit cold bridging.
• Loft conversions & ceilings where a slimmer internal layer is preferred.
• Hallways, stair cores, small rooms—anywhere tight spaces demand a thinner lining.
• Retrofit projects seeking better comfort and energy efficiency with minimal thickness.

Installation Tips for Standard Plasterboard

• Prep the surface: Substrate must be sound, dry, and dust-free. Pack out or strap uneven walls.
• Board orientation: Insulated face to the cold side, plasterboard face to the room side (check the specific product).
• Fixings: Use appropriate-length drywall screws into battens/straps or approved direct-fix anchors. Follow the recommended fixing centres.
• Vapour control: Where a foil facer/VCL is present, tape all joints and perimeters; seal penetrations (sockets, pipes) to maintain continuity.
• Joints & finishing: Stagger board joints; tape & joint or skim to finish. Prime before painting.
• Services: Avoid recessing boxes so deeply that you puncture the insulation layer; if you must, re-seal the VCL around penetrations.
• Safety: Cut with care (score & snap or fine-tooth saw), manage dust, and wear appropriate PPE.
