Analysing the phenolic insulation system

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?

Phenolic 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.

Garage door insulation types - which is better???



  1. Reflective Foil
  2. Panel Foam with foil face
  3. Fiberglass with vinyl backing

I live in Austin, TX and it gets hot here 9 months out of the year.

I've been reading numerous threads for the last 3 hours and most garage doors seem to be insulated with foam panels, some with radiant barrier foil.

My plan is to cool my garage with a portable AC unit for the time being. Again, after reading numerous threads, I now know the portable isn't a good solution but it's what I have until I can sell it.

In the mean time I'm going to start insulating my attached garage... and I'm going to start with the doors as they are giant heat sinks. 2 of the 3 walls are insulated for sure, and I'll be checking the 3rd wall this afternoon.

The ceiling has zero insulation so that will be step number 2. Step 3 will be either insulting the 3rd wall, depending on what I discover today, or selling the portable and installing a split system (depending on the HOA).

When I'm working in my garage, I'll be in there typically 8+ hours a day, mainly wood working or some other project to keep me busy when I'm not offshore working.

I like the reflective foil because it covers the entire door and metal framing, but since it attaches to the metal framing, I would expect the foil to become conductive and less of a radiant barrier. Not totally sure how that works with foil on metal for a relatively small section and a large air gap for the rest of the door.

The foam boards do roughly the same thing as the reflective foil, but it does not cover the metal bracing/framing attached to the door. On my two, single width doors, the metal bracing runs down the middle. So, any heat transfer will radiate into the garage, but that surface area is relatively small to the overall door surface area.

The fiberglass option leaves me with the same exposed door bracing to transfer heat, but it has the highest R value.

Taking the cost out of the equation, and selecting from these three options, what is to best form of insulation for my (2) 9' wide, west facing doors?
