Phenolic Insulation Boards
High-performance phenolic insulation where space is tight and thermal targets are demanding. We currently stock and supply Phenolic PR/UF Boards to help deliver a strong thermal efficiency at reduced thickness, ensuring you keep build-ups slim without compromising on specification. Orders are prepared quickly for collection from Burgess Hill, Whitstable or Eastleigh, or delivery can be arranged to site. Cut-to-size is available from our West Sussex and Hampshire depot for neat edges and faster installs.
Phenolic insulation boards supplied here at Johnson’s Insulation Supplies can be used in floors, walls and roofs when you need lower U-values at practical depths. Typical applications of a phenolic PR/UF board include:
- Below or above screed floor build-ups
- Timber frame sheathing and internal lining
- Warm flat roof systems and over-rafter pitched roofs
- Upgrades where every millimetre counts
Why choose phenolic board insulation?
- Very low thermal conductivity for thinner constructions
- Rigid phenolic insulation board with consistent tolerances for a clean fit
- Helps reduce cold bridging at junctions when accurately cut and planned
- Supports programme speed with fewer layers to reach the target value
