We have been providing the UK with numerous forms of fire protection for many years. One of these solutions is thermal insulation. The team can install glass fibre, mineral wool, and even phenolic board. In addition, we aim to meet the standards set out in Part L of the Building Regulations.

What is it?

Thermal insulationPhenolic insulation is a topic we would like to discuss in more detail. You manufacture this using a technique where a plastic foam produces an insulating core. Said core lies between two layers laced with flexible tissue. It possesses a fine cell structure and high closed cell content.

Rigid phenolic boards are made by merging resin and high solids with a surface acting agent. The heat from the reaction vaporises a volatile liquid blowing agent in the mixture. This creates a network of compact bubbles in the material. You can cure the foam to produce one of two variants of the product.

Low thermal conductivity

This type of insulation can provide great thermal insulating attributes. This is thanks to the low thermal conductivity of the foam. It can be 50% more efficient than some other materials.

Due to the low thermal conductivity, you can also achieve very strict thermal performance targets with minimal insulation thickness. This is vital when you need to save space. Speak to us if you need thermal insulation.

Physical qualities

There are many physical qualities of this insulation to take note of too. Firstly, there is moisture resistance. It does not have much of an effect on the insulation’s thermal performance. In fact, the boards have a 95% closed cell content or more. It is this characteristic that lets them defend against moisture. Moreover, the material comes with a low water vapour permeability.

The phenolic foam is non-wicking too. As a result, moisture ingress is low. This prevents the moisture from accumulating, even if there is an issue with the vapour barrier.

Fire performance

Another vital characteristic of the phenolic insulation is its fire performance. It combines very low or zero flame spread with low smoke emission as well as a low degree of toxic gas emission. People use the foams with minimal thermal conductivity as alternatives to PIR or PUR foams. They do so where they require a low smoke emission, self-extinguishing material.
