Absolutely. Wall insulation prevents your home from heating up in summer and keeps your home warmer in winter. Around 15-20% of a home's heat loss and gain occurs through the walls. Without adequate insulation in your walls, heat would pass in and out of your wall material without much resistance.
Energy Savings – Upgrading your wall insulation can help reduce energy loss, leading to better energy efficiency and lower heating and cooling costs. Noise Reduction – Insulation has sound-proofing properties and can help dampen noise. If you live on a busy street, installing wall insulation can make a huge difference.
Wall insulation is one of the most effective ways to improve the energy efficiency and comfort of your home. It can reduce heat loss in winter and heat gain in summer, lowering your heating and cooling bills.
Exterior walls are one of the primary barriers between your home and the outside environment. Without proper insulation, this barrier is compromised, allowing cold air to seep into your home during winter and letting cool air escape in the summer.
Interior walls are often left uninsulated during construction because the energy efficiency benefits are less significant than those gained from insulating exterior walls, floors and ceilings.
It is possible to over-insulate your house so much that it can't breathe. The whole point of home insulation is to tightly seal your home's interior. But if it becomes too tightly sealed with too many layers of insulation, moisture can get trapped inside those layers.
Irritation to skin and respiratory system
Wall insulation solutions like Rockwool are made of ultra-fine fibres. While thermally efficient, they can cause skin and respiratory irritation.
The average cost to insulate a wall is $2,400, but it often ranges between $1,150 and $6,000, depending on the project scope and materials your installation pro uses.

Lifespan of cavity wall insulation materials
Polystyrene beads can last up to 100 years due to their resistance to moisture and decay. Polyurethane foam and mineral wool are durable, typically lasting over 50 years. Extruded polystyrene (XPS) has a 20—to 30-year lifespan, and fibreglass can last 80—to 100 years.
Foam Board or Rigid Foam
Foam boards -- rigid panels of insulation -- can be used to insulate almost any part of your home, from the roof down to the foundation. They are very effective in exterior wall sheathing, interior sheathing for basement walls, and special applications such as attic hatches.
Thermal lining paper is among the cheapest ways to insulate internal walls. This thick, insulating wallpaper can be easily applied directly to walls, making it a quick and straightforward solution. Costing around £10 per square metre, it effectively reduces heat loss and is perfect for smaller DIY projects.
The best, and most common, method for adding insulation without removing drywall is through the drill-and-fill method. Using the drill-and-fill method, the insulation is blown directly into a closed wall through small holes drilled into the wall.
EPA estimates that homeowners can save an average of 15% on heating and cooling costs (or an average of 11% on total energy costs) by air sealing their homes and adding insulation in attics, floors over crawl spaces and basements.
Can be messy during installation – The loose cellulose fibers blown into a home during the insulation process produce significant dust during installation, which can create a mess for homeowners.
Reduced energy bills
External wall insulation will improve heat retention in your home, which in turn reduces your energy bills. This is because when less heat escapes from your home, your heating system doesn't have to work as hard to get to the right temperature.
Never place insulation close to water heaters, oil burners or anything hot. The backing is especially flammable and will be a major fire hazard for your home.
A well-insulated home can also significantly impact its resale value. When it comes to buying a house, potential buyers look for features that will save them money in the long run. And insulation is one such feature that can positively affect the overall value of a home.
Yes, insulating interior walls can improve energy efficiency, reduce noise, and enhance comfort, but it's essential to weigh the benefits against the costs and potential drawbacks.
Many of us know what causes mould; when moisture is trapped in the rooms of you home. Sometimes, there is insufficient insulation in the walls, so mould grows. However, not many people realise that additional insulation isn't always the answer. In fact, too much insulation can be the secret cause of mould.
While insulation is one of the best ways to reduce unwanted noise in new homes, building codes mostly require that exterior walls be insulated, and it's not customary for the interior walls of homes to be insulated.
