Best Insulation Types for Homes

With the internet and the abundance of information we have these days, it’s fair to say that the importance of home insulation is now understood. In short, between 50% and 60% of all heat loss goes through the walls and roof. By padding these areas, less heat escapes, we don’t need the heating on for so long, and we can save our hard-earned money.

This is great, but what types of insulation actually exist? We’re going to go through the main offerings in this guide!

Loft Insulation

Rockwool Loft Insulation – Perhaps the most common choice of all, this is ideal for cold roofs and generally works well (so long as it is laid correctly!). As a combination of recycled slag and basalt rock, the final product is vapor permeable while remaining moisture resistant. 

Multi-Layer Foil Insulation – Sometimes, not all forms of insulation are possible to use, and this is where multi-layer foil insulation comes in. When bubble foil and single foil products started to have problems with condensation, this solution was developed and introduced as a replacement. 

Aluminum Foil-Backed Insulation – If there are areas in the roof or loft that need guarding against heat, aluminum foil might be the perfect choice because the material reflects light. Additionally, having the foil facing inside will reflect the heat back into the home rather than being allowed to escape.

Wall Insulation

Cavity Wall Insulation – Used as a general term, there are many potential materials used for cavity wall insulation; this includes polyurethane foam, fiber wool, and polystyrene beads (or granules). These days, mineral wool is the most common choice. 

Rigid Foam Insulation – Again, there are different types of rigid foam insulation. However, they all have the same purpose; they use solid boards and sheets of material. As a closed cell material, it’s a rigid surface rather than using soft mats and other loose options. 

Blown-In Insulation – As the name suggests, this product is either sprayed or blown into the wall. Although designed for the walls in a home (since it causes minimal damage and disruption), there’s no reason why you can’t also blow insulation into attics and floors. In most cases, this will be a foam solution. 

Blue Jean Insulation – Sometimes referred to as ‘denim’ insulation, you might be more familiar with this material on clothing, but it is also a high-performance insulation too. Of course, there are differences between the clothing and insulation, but it all starts in the same place. Rather than throwing away the clippings and scraps from denim clothing factories, they provide the foundation for recycled denim insulation (so it’s also an environmentally friendly option!). 

Sheep’s Wool Insulation – This time, we’re looking to nature and a material that sheep themselves grow in order to stay warm; wool. In wool, there are millions of small air pockets created in the fibers. Therefore, this results in a thermal barrier and shouldn’t allow for heat inside the home to escape. 

Finding a Solution

Even after our list, there are still more options. If this is causing headaches, don’t allow yourself to be confused by the many products. Rather than looking at loose fill insulation, rolls, batts, and boards, start with your own needs. Too often, we find people shaping their needs to a product when they should be doing the opposite and shaping the product to their needs.

If you don’t even know where to start, have somebody come visit your home. They will assess the walls and roofing before then providing advice on the best insulation choice!
