How internal wall insulation works

At Outlook Energy Solutions, we’re experts in professionally installing internal wall insulation. We follow the same procedure for different types of properties, ensuring all solid walls are efficiently insulated.

It’s important to remember that internal wall insulation not only makes a home energy efficient in the winter, by keeping warm air contained, but it keeps homes cooler in the summer by keeping heat out.

Here is the process we follow for every internal solid wall insulation installation.

Wall survey

First, a solid wall survey is performed to determine the condition of the existing wall and the required logistics for installing internal wall insulation.

Walls prepared

We will then prepare the wall for internal insulation. Any issues with penetrating or rising damp are resolved before installation.

Installation

Rigid insulation boards are installed to internal walls, or a stud wall is built filled with insulation material such as mineral wool fibre.

Warmer home

As a result of the insulating materials installed, the home will feel warmer. Why? Because internal wall insulation creates a barrier to stop warm air from leaving through your solid walls.

Energy bill savings with internal wall insulation

Have your energy bills crept up? Are you finding it tougher to keep your home warmer for longer? Well, with internal wall insulation, you can increase the energy efficiency of your home with our high-quality insulation materials.

Here’s how much you can save on your annual energy bill with internal wall insulation depending on the type of property you live in.

Benefits of insulation

Reduce energy bills

With internal insulation for solid walls, you can save a lot of money on your energy bills. Without proper internal wall insulation, heat will escape, meaning you need to leave your central heating on for longer, costing you more money.

Reduce heat loss

Internal wall insulation for solid walls helps to keep your home warmer for longer. Installing solid wall insulation to an existing wall inside your home will keep heat loss at a minimum, ensuring your family is warm and comfortable through the cold, bitter winter months.

Save energy

The insulating material we use for internal insulation will reduce the amount of wasted energy in your home, lowering your heating bills.

Lower carbon footprint

An internal solid wall insulation installation helps the environment by contributing to lower carbon emissions. If going green is important to you then internal wall insulation can help.

Funding available with government-backed grants

As part of the UK government’s initiative to cut carbon emissions, grants are available to fund energy-efficient upgrades to homes with low energy ratings.

If you are living on a low-income or receive income-related benefits, you could be eligible to receive full funding for home insulation, air source heating and solar panel energy.

Internal Wall Insulation FAQs

What is internal wall insulation?

Internal wall insulation involves insulating the interior face of external walls to improve the thermal performance of the home.

There are several ways of installing solid wall insulation, and one of the most common is to build a stud wall filled with insulating material.

Internal wall insulation can be disruptive and may require the removal and re-fixing of radiators, kitchen units, and light switches, etc.

It is essential to create an airtight barrier to retain heat within the home. This could require work on awkward areas like floor space and reveals.

What type of insulation materials are used by internal wall insulation installers?

There are many different types of insulation materials used by internal wall insulation installers. They include:

Blown mineral fibre, polystyrene beads, and urea-formaldehyde foam – Often used for cavity walls.

Mineral wool – Can be installed in rolls or batts and can be attached to the wall or between wall studs.

Rigid foam boards – Made from materials like expanded polystyrene (EPS), extruded polystyrene (XPS), and polyisocyanurate (PIR).

Natural fibre – Made from materials like sheep’s wool and hemp. It’s sustainable, environmentally friendly and offers excellent thermal performance.

Does internal wall insulation cause damp problems?

If installed correctly, internal wall insulation does not cause damp problems.

However, condensation and moisture can build up if installed incorrectly.

Some installation considerations include:

Ensuring there’s plenty of ventilation.
Don’t install where there is already damp; this must be repaired.
Install a vapour barrier; a damp-proof membrane will prevent moisture from penetrating the walls.
Use breathable insulation materials.

Am I eligible for free internal wall insulation?

The UK government is determined to cut carbon emissions so is providing grants to fund energy-efficient upgrades to homes with a poor energy performance certificate rating.

If you receive income-related benefits or you’re living on a low income, you may be eligible to receive full funding for internal wall insulation and more, including loft insulation, air source heat pump installation and more.
