How thick should furring strips be?

Furring strips are used for insulation. Furring strips are made from different materials. There are two types of furring strips: rigid foam and flexible foam. Each type has its own advantages and disadvantages. This article will tell you which material is best suited for your application.

What is Furring Strip?

The term “furring strip” refers to the insulating material used for insulation. Furring strips are used in many applications such as fire protection, medical equipment, electrical wiring, and so forth.

They have been around since the 1930’s when they were first invented.

How Thick Should Furring Strips Be?

There are two kinds of furring strips: rigid foam and flexible foam. Both types of strips have their pros and cons.

For example, rigid foam strips tend to be thicker than flexible ones. If you want to make sure that your insulation will last longer, then it would be better if the thickness of the furring strips is at least twice as thick as the thickness of the insulation. You may need to use four times as much furring strips than what you think. Also, the thicker the strips are, the longer it takes to cut them. If you are using a jigsaw, then it needs to be a powerful one in order to cut through thick furring strips. You can also use a miter saw or even a table saw if you want.

If you prefer flexible foam strips over rigid foam strips, then be aware that flexible strips are more prone to bending and warping due to temperature changes so proper preparation is very important. You can use caulk or spray foam in order to fill up cracks so the flexible foam strips will not bend as much.

Here is a detailed guide about how to lay flexible furring strips.

It is very important to calculate the correct amount of furring strips that you will need before starting your project. Otherwise, you might run out of materials while in the middle of a project and this is very expensive to buy while in the middle of a project.

We recommend that you buy 10% more than the amount that you need because there is a possibility that some of these may get damaged.

The first thing that you need to do is measure the wall or ceiling that needs to be insulated properly. Make sure that you have all the necessary materials before starting your project.

If you already have plywood installed on your walls, then it would be easier for you to install rigid foam furring strips. If you do not have plywood installed on your walls yet, then you may need to install it before installing rigid foam furring strips. You can watch this video about how to install plywood on a wall.

Now that you have all your materials ready, you may start installing rigid foam furring strips on your walls. The first thing that you need to do is cut the rigid foam material using a jigsaw.

Be very careful when doing this because if you make just one wrong cut, then the whole piece of rigid foam material will be useless. You need to make sure that the cuts are straight and neat. If you do not know how to use a jigsaw, then you may get help from a friend or hire someone that knows how to use one.

After making all the necessary cuts, now you can start installing rigid foam furring strips on your walls. Make sure to install them at an angle so that it is easier for you to add the flexible strips in between the rigid strips.

Make sure that all the edges are sealed properly using caulk or spray foam in order to avoid air leaks.

In this video, you can see how rigid foam furring strips look like while installed on a wall. If you want the best R-value insulation, then you may also add another layer of flexible strips on top of the rigid strips.
