This article serves as a cavity wall insulation polystyrene beads guide that will help you make the right decision for your home. It also highlights some problems you might face and a few factors you need to consider. The problem is that, in some cases, the beads might lose some of their insulation and water resistance properties. However, polystyrene beads are forgiving and much easier to install. That’s because they’re small and can reach awkward areas without having to drill multiple holes in your walls.With a λ-value of 0.034 to 0.040, you can count on EPS beads to keep your house warm. This λ-value puts it between polyurethane and mineral wool in terms of its effectiveness. Things to Consider Before Installing Polystyrene Beads On the bright side, EPS beads don’t absorb moisture as much as other insulating materials. When installed correctly, these beads create flawless insulation with the help of the bonding agent, making it relatively water resistant.

Is there any risk of condensation (dew point) forming on joist ends with the bead insulation in situ? Don’t fret! You can avoid the issues we’ve mentioned by following these steps: 1. Make Sure Your House Is Suitable So, you’re probably wondering, what makes these beads a better option? And are there downsides to using them?

Unfortunately, EPS cavity wall insulation isn’t perfect. There are some things you need to consider before installing this material inside your walls. 1. Poor Installation Can Do More Harm Than Good Polystyrene beads are the most popular cavity wall insulation material these days. Here’s why you should consider using them: 1. Ease of Installation and Flowability There are two types of polystyrene beads that are used in home insulation: Expanded Polystyrene (EPS) and Extruded Polystyrene (XPS).

In addition, the cavity should be at least 50mm wide to be suitable for this kind of insulation. 3. Gaps Can Still Happen These mistakes can be anything from insufficient bonding material to improper injection, leading to cold spots and structural damage. Wall cavities tend to get dirty and gritty over time. Unfortunately, installing EPS in a dirty cavity might lead to inadequate insulation.Polystyrene beads are the most popular cavity wall insulation material for many reasons. They’re more forgiving and easier to install. Additionally, they’re durable and lightweight, which decreases the risk of structural damage. At first, polystyrene is fed into moulds to create tiny beads. Then, heat or steam is applied to the mould, leading to the expansion of the beads, hence the name. While polystyrene beads are more forgiving than other insulating materials, installation mistakes might cause various issues. So, you must make sure the installer cleans the cavities or hires someone to do so before the EPS installation. This process might be costly, depending on the state of the cavity, but it’s essential to insulate your house properly. Effective cavity wall insulation starts with finding a certified, reputable installer. Ideally, you should be looking for an installer who offers a guarantee for their work.
