What does Home Insulation involve? 

Home insulation prevents heat from escaping from your home by using a variety of methods. The most common technique is adding a physical barrier between your walls and the outside elements. Home insulation is a popular home improvement as it significantly reduces your energy bills while making your property more energy-efficient.

What impacts the cost of Home Insulation? 

As you can see, the price of home insulation can vary widely, so it’s important to know what option works best for your budget. Not every type of home insulation is going to break the bank, and there are options to suit most budgets. 

Remember, home insulation is an investment in the long-run, as you’ll reap the rewards of lower energy bills for years to come. 

Here are some key price factors to consider: 

  • Type of insulation

  • Cavity wall 

  • Draught proofing

  • Floor 

  • Loft 

  • Solid Wall 

Types of Home Insulation Prices
Type of insulationHighest average price Lowest average price
Cavity wall $2,900$1,400
Draught proofing$260$60
Floor (batt/roll)$2,300$1,000
Solid wall (blown In)$4,500$1,000

The great thing about home insulation is that even the cheapest option of draught-proofing (around $60) can have a big impact. Most services are around $1,000, which is much cheaper compared to other types of home improvement. 

If you want to opt for solid wall insulation, this will cost you a lot more, between $1,000 and $4,000. But the upside is that you’ll get the best protection against overall heat loss. 

In some cases, you will be able to get the cost of home insulation covered by government schemes. 

Cavity wall insulation

Cavity wall insulation reduces heat loss by filling the airspace between the layer of bricks with an insulating material. It’s a relatively quick and simple process - your installer will usually need to drill a series of holes at various points in your brickwork, before filling it with a material. Common materials include polystyrene beads, mineral wool, or polyurethane foam. The average cost is between $1,400 - $2,900

Draught Proofing

If there are some areas of your home which are particularly chilly, then you probably need to get someone in for draught-proofing. Draught proofing removes gaps where heat is escaping from your home. It’s the most cost-effective home insulation technique, averaging at around $60 - $260 to complete. 

Floor insulation

Floor insulation involves inserting a layer of heat-trapping material beneath your floorboards to prevent heat from rising and escaping through your roof. Floor insulation prices can vary quite a bit, between $1,000 - $2,300. Remember that you may also need new flooring in the process as your carpet will need to be removed to access the floorboards - this will be at an additional cost. 

Loft insulation

Did you know that around a quarter of your home is lost through your roof? The good news is that loft insulation can be an affordable solution to the problem. Loft insulation involves adding a thick material in your roof space, usually along the rafters or joists. This will act as a barrier to prevent heat from rising and escaping through the roof. It costs around $640 - $2,600 and it’s a fairly straightforward installation process. 

Solid wall insulation 

If you live in an older property that won’t benefit from cavity wall insulation, solid wall insulation is an effective alternative. This involves adding insulation boards to the external walls of your home. Your installer will then add a base coat and a mesh over the top of the boards to ensure that they are resistant to impact. The benefit of solid wall insulation is that it improves the look of your property as well as minimizing your energy bills. Solid wall insulation is generally more expensive than other types of insulation, averaging at around $1,000 - $4,500. It also works wonders for minimizing damp or mold issues caused by faulty or lack of rendering.

Home Insulation - is it worth the cost? 

Home insulation is a great solution if your home is older, generally draughty, or has high energy bills. Regardless of the type of home improvement that you opt for, it will make your home more comfortable, energy-efficient, and lower your energy bills - the money you’ll save later down the line will be well worth the investment.
