While a phenolic insulation board is a more expensive form of insulation, its performance is unrivalled. For many, it’s regarded as one of the most thermally efficient insulation products currently used. This is due to a number of benefits:

• Phenolic insulation boards are one of the thinnest insulation boards for a specific u-value, meaning they’re incredibly space efficient.
• Phenolic insulation boards offer excellent moisture resistance. Their company cell structure prevents moisture absorption and water vapour penetration, ensuring that the insulation remains effective and durable over time.
• The boards are also resistant to certain types of fungus and mould growth, further enhancing their longevity and structure integrity.
• In terms of safety, phenolic boards are designed to withstand high temperatures. They can withstand continuous temperatures of up to 120 °C.
• Phenolic boards have zero or very low flame spread, produce negligible smoke emissions and release a minimal amount of toxic gases when exposed to fire.
• While phenolic insulation is non-biodegradable, you can put the waste material back into the manufacturing process for reuse, and its outstanding thermal properties help reduce CO2 emissions.
