How to Install Foam Insulation Without Removing Drywall

About Icynene

If you’re renovating or moving into a new home, it’s crucial to ensure you have good insulation in place. In most homes, especially older homes built before the 1970’s, insulation often significantly lacks. Walls without a tight air seal can cause a whole trail of uninvited problems, such as cold drafts and staggering energy bills because your heating system is overworked.

Considering this, you’re probably wondering: can I do this without tearing down drywall? Thankfully, the answer is yes. We’re going to help you save time and money by showing you how to install spray foam insulation in your home without removing drywall.

Start by insulating your loft

Loft insulation under your roof is always a good place to start when you want to insulate your house without touching drywall. This is because your roof is the place where added insulation has the most positive impacts on your home. You can do this by using spray foam insulation between roof rafters to fill cavities. Then, any excess can be trimmed off later for a neat finish.

Cavity wall insulation

If you’re looking to insulate your walls with expanding foam insulation, this can be done with no fuss necessary. Spray foam is perfect for cavity wall insulation as a few small holes can be drilled into the wall, which can be easily patched up later. The spray foam insulation is then injected into the cavity. A good way to tell when this is full is by feeling the back-pressure on the hole.

Why is spray foam insulation the best option?

Icynene spray foam insulation has an array of benefits to effectively insulate your house without the hassle of removing drywall. One huge perk is that spray foam has the ability to prevent mould and mildew, compared to other insulation methods such as fiberglass and loose fill. Furthermore, spray foam insulation can squeeze its way into every tiny nook and cranny, which other insulation materials often miss. It is also the best option to avoid damaging your drywall, so it’s less laborious and more cost-effective.
