Roof Insulation Types

You may not realise, but much of the heat that escapes from your home goes through your roof. When you also factor in that lots of cold air from outside also comes in the same way, it’s clear why effective roof insulation is well worth the investment. But what are the most common types of roof insulation you could choose from?

Spray Foam

One type of roof insulation which is becoming very popular is spray foam insulation. This is a very versatile method which uses a liquid foam that is sprayed where needed. Once in place it quickly sets, proving effective at stopping heat from escaping and cold air from entering. Although it isn’t the cheapest option, spray foam is still the most popular option thanks to its superior insulation properties and how easily it can be used to fill those hard-to-reach spots.

What are the advantages of using open-cell spray foam? 

  • Typically, buildings expand and contract due to temperature differentials, moisture content, wind load and seismic etc. Closed-cell insulation cannot accommodate the movement of the building. 
  • Open-cell spray foam: Provides air sealing benefits in many applications at lower cost. Vapor permeability supports bi-directional drying of assemblies – critical in warm climate zones/seasons. Flexibility allows it to expand and contract with any movement of the building structure ensuring long term air sealing. Water-blown product maintains a lower GWP (GWP 1) than most closed-cell products.

What are the advantages of using closed-cell spray foam?

  • Density – Compared to other insulation materials, closed cell spray foam insulation is denser, and consequently insulates better throughout your home.
  • R-Value – The R-value of insulation is its resistance to heat flow. This is an important factor when choosing your insulation materials. Closed call spray foam has a high R-value, and therefore offers an extra layer of protection.
  • Durability- While other insulation materials may lose their effectiveness over time, this does not affect closed cell spray foam meaning this choice will be a good investment for future thinking.

Blanket Insulation

Blanket insulation is another common form of roof insulation seen in homes. It’s available in rolls of various insulating materials such as fibreglass wool or foil-backed felt, which are great materials to retain heat. This sort of insulation is fairly inexpensive and can be installed yourself if you are happy with trying some DIY. The downsides are that some materials used in blanket insulation can cause irritation to the skin and, as it’s also one of the bulkier forms of insulation, it isn’t ideal for smaller spaces. It also does not keep as much heat in as other types, like the aforementioned spray foam loft insulation.

Loose Fill

Another type you could use is loose-fill insulation. Although most commonly made from more granular materials such as granules of cork, loose-fill insulation can be crafted using a myriad of materials, including recycled newspaper! While this sort is good for insulating irregular spaces and is usually eco-friendly and cheaper, it can come loose and need regular upkeep. As with blanket insulation, it does not offer the same level of insulation like spray foam.
