Phenolic insulation is a rigid, lightweight foam made from phenolic resin with a closed-cell structure.

A wet foam mixture is applied directly to the lower facing layer, where it expands upward to contact the upper layer. This process forms small airtight cells that trap gas and limit heat transfer. The material is cured under controlled heat and pressure.

Our Safe-R 019 range offers a thermal conductivity of 0.019 W/mK. This range offers different solutions depending on your project needs. Our Safe-R range also offers various solutions depending on your project and has a thermal conductivity as low as 0.021 W/mK.

Phenolic insulation is considered one of the most thermally efficient insulation products, providing high R-Values in thinner board compared to other insulation materials.

Phenolic Insulation boards can be used in many applications or projects. Whether you are looking at a new build, a renovation project, commercial or residential, Phenolic insulation can be considered for your project. It can be used in roof, walls, soffit and floor applications, making it a viable solution for a variety of constructions.

Lower Lambda (thermal conductivity) values for improved U-Values

Reduced Insulation Thickness

Suitable for a variety of applications

Cost-effective solution in refurbishment and new build

Phenolic Insulation works by reducing the transfer of heat through a building’s wall, roof, floors and other structural components.

The lower the thermal conductivity in the phenolic insulation, the higher its insulating capacity.

Heat conduction and lambda value 

As it has a low thermal conductivity it is difficult for heat to pass through it, which  makes it is such a good insulator.

R-Value 

A low lambda value (Thermal conductivity) results in a high R-value or thermal resistance, a measure by which we assess specific insulation products in relation to their insulation thickness. This thermal resistance quantifies the area and temperature difference needed to transfer 1W of heat energy. The higher the R- value, the lower the amount of heat loss.

The low lambda value of Phenolic means that anyone working with the product can insulate a building comfortably thanks to its thickness while optimising the energy performance. With Phenolic, you can make the most efficient use of the space available to you. Since you need less insulation material overall, this is the definition of a smart investment.

The fire rating of Unilin Insulation Phenolic laminate range has a high Euroclass rating of B-s1,d0. This applies to our SR019/TB-MF, and SR019/STP products. It is important to check the fire rating of each product when specifying, as fire ratings typically vary depending on their application

In some projects, it may also be advisable to choose a combination of materials in order to achieve the best result for your project.

For Example, our Stonewool products offer a non-combustible solution.

Alternatively, our ECO360 Range offers our optimum sustainable option.
