How To Install Insulation In Walls: The Essential Guide

how to install insulation in walls

If you’re looking for information on how to install insulation in walls, it’s important that you find informative and correct details on the different types of insulation available, their suitability for the walls in your home.

Whether you’re looking to install bare walls with joists and rafters before an internal wall is laid, or to insulate an existing wallmay dictate what type of insulation you opt for.

The most common form of wall insulation is fibreglass insulation which comes in rolls and can be adhered to the bare interior of a wall before an internal wall is laid over it.

Fibreglass insulation is cheap, but limited in its efficiency, as it deteriorates over time and easily absorbs moisture, making it a festering ground for mould and a bridge for damp.

Fibreglass insulation acts as a small barrier against cold air flow into the home but is easily penetrable and so does not create a full building envelope to protect the property within.

Installing fibreglass insulation is very difficult to do with existing walls in place, as it will require tearing these down or at least removing a portion for access to stuff it into the cavities. There are considerably easier – and more effective – options available.

With that in mind, we explore the main wall insulation options on offer in greater detail…

Spray Foam Insulation: The Basics

Spray foam insulation is an industrial foam that can be applied either to new-build or existing walls. In the case of the former, spray foam insulation is sprayed directly onto the walls surface with specialist equipment. 

For existing walls, the solution can be injected in through small holes.

The nature of spray foam insulation being a spray foam is that it expands to fill the space around it. This means that when sprayed or injected, it will grow into the area; sealing off even the hardest to reach nooks and crannies.

Spray Foam Prevents Thermal Bridging

Spray foam insulation entirely blocks air flow and is water-resistant, so will act as a thermal block, rather than a thermal bridg,e between your exterior and interior walls.

This promotes a drier and warmer environment within the home with less energy usage within. Existing customers estimate saving up to 40% on their heating bills as a result of having spray foam insulation installed.

One customer who already has spray foam insulation installed says on product review website TrustPilot: “Over time I noticed a significant difference my home felt insulated against noise and the boiler was not kicking in as much as I use temperature control. My direct debit payments have decreased by £30 a month on my gas and electricity bills”!

Saving Money… And The Planet!

With lesser energy usage and lower bills comes higher energy efficiency. This makes spray foam insulation particularly popular with local authorities and estate agents, and will have a tangible impact on EPC (Energy Performance Certificate) grading.

A property with a higher EPC rating is considerably more desirable to prospective buyers, making it a worthwhile, long-term investment.

Improved Indoor Air Quality

Spray foam insulation contains no pollutants, and will not release any into the environment around it. The dried foam also won’t degrade or allow mould to grow, preventing airborne spores from entering the home. 

Those with any conditions caused or aggravated by airborne irritants, such as asthma, will notice an immediate difference in the internal air quality within the home.
