Phenolic Insulation

Phenolic insulation is a high-performance, rigid insulation material with a closed-cell structure that provides exceptional thermal efficiency, moisture resistance, and fire safety. Made from a phenolic resin core, this insulation has low thermal conductivity and impressive fire-resistant properties, making it ideal for projects where space, safety and efficiency are paramount. 

Insulation UK specialises in Phenolic Insulation products. Our range includes both phenolic boards and foams for a variety of applications, including floors, walls, and roofs.

Benefits of Phenolic Insulation

• Unmatched Thermal Efficiency: With thermal conductivities as low as 0.018 W/m·K, phenolic insulation provides exceptional thermal resistance, reducing energy costs and maintaining indoor comfort.

• Space-Saving: Due to its high insulation values, thinner phenolic insulation boards can achieve the same performance as thicker boards of other insulation materials.

• Fire Safety: Phenolic insulation has excellent fire resistance, producing lower smoke and fewer toxic gases compared to other insulations, which is ideal for applications with strict fire regulations.

• Moisture Resistance: Its closed-cell structure makes phenolic insulation resistant to moisture, ensuring longevity and performance even in damp areas.

• Eco-Friendly Solution: Phenolic insulation supports energy efficiency and can reduce heating and cooling needs, promoting eco-friendly building practices.

Frequently Asked Questions 

What applications are phenolic insulation best suited for?

Phenolic insulation is ideal for applications where space, fire safety, and high thermal performance are priorities. It is commonly used in floors, walls, and roofs and is especially beneficial in areas requiring thinner insulation.

How does Kingspan Kooltherm compare to other insulation types?

Kingspan Kooltherm phenolic insulation offers one of the lowest thermal conductivities available (around 0.018 W/m·K), which is better than PIR, EPS, and other rigid insulation types. This allows for thinner layers to achieve the same thermal performance, making it ideal for space-sensitive projects.

Can phenolic insulation be used in high-moisture environments?

Yes, phenolic insulation is resistant to moisture, making it suitable for applications where water resistance is needed, such as in basements or walls that may be exposed to damp conditions.

What are the fire safety benefits of phenolic insulation?

Phenolic insulation has high fire resistance, producing low levels of smoke and toxic gases when exposed to fire, making it ideal for applications with strict fire safety regulations.

Is phenolic insulation environmentally friendly?

Yes, phenolic insulation promotes energy efficiency, reducing the need for heating and cooling and supporting eco-friendly construction.
