Internal wall insulation

Types of internal wall insulation

There are a few different ways to install internal wall insulation. Here are the main types of internal wall insulation commonly used in the UK:

Rigid Insulation Boards

These boards, often made from materials like PIR or polystyrene, are fixed to internal walls to provide excellent thermal insulation with a slim profile. They’re ideal for reducing space loss while improving energy efficiency.
Insulated Plasterboard

A combination of plasterboard and insulation material, these boards make the process simpler by providing both insulation and a surface ready for decorating.
Flexible Thermal Linings

Thin, lightweight rolls or sheets that are applied directly to the wall surface. While less effective than thicker solutions, they can still help reduce heat loss and are great for tackling smaller areas.
Stud Wall Insulation

This method involves building a stud wall in front of the existing wall and filling it with insulation material like mineral wool or rigid boards. Though it reduces room space slightly, it provides highly effective insulation.

Benefits of Flat Roof Insulation Installation

Fitting internal wall insulation offers a range of benefits, making it an effective choice for improving home energy efficiency. Here are the key advantages:

Reduced Heat Loss

Installing internal insulation helps prevent heat from escaping through walls, keeping your home warmer for longer.
Lower Energy Bills

By improving your home’s insulation, your heating system doesn’t need to work as hard, reducing your energy costs.
Increased Comfort

A well-insulated home maintains a more consistent and comfortable indoor temperature.
Carbon Footprint Reduction

Lower energy usage means fewer greenhouse gas emissions, making it an eco-friendly option.
Improved Soundproofing

Insulation can also help reduce noise from outside or between rooms.
Suitability for Older Homes

Ideal for properties with solid walls (commonly built before the 1920s), which often lack cavity walls and are prone to heat loss.
Enhanced Property Value

Improved energy efficiency can make your home more appealing to buyers and increase its value.

How much money can you save by installing internal insulation?

The amount of money you can save by installing internal wall insulation depends on the size of your home, the level of heat loss through your walls, and the cost of heating.

Annual Savings: According to the Energy Saving Trust, installing internal wall insulation can reduce heating bills by up to £550 per year for homes with solid walls.
Reduced Energy Usage: Adding insulation to interior walls allows your heating system to operate more efficiently, using less energy to maintain warmth, which directly lowers costs.
