What is the difference between EPS and XPS?
Last updated April 21st, 2023
If you’re looking for an efficient and cost-effective solution to insulate your property, then EPS (expanded polystyrene) and XPS (extruded polystyrene) are two commonly used materials that you may want to consider. However, when it comes to using these materials in a cavity closer, EPS is the better option for several reasons.
What is a Cavity Closer?
First, let’s start with what a cavity closer is. A cavity closer is a product used to seal the gap between the inner and outer leaf of a masonry wall in a building, around windows and doors. It helps to prevent heat loss and draughts and ensures that the cavity is fully insulated.
Why EPS is better to use in a cavity closer than XPS
- Better insulation properties: EPS has a lower thermal conductivity compared to XPS, meaning that it provides better insulation with less material. This is important in a cavity closer, as you want to make sure that there is minimal heat loss and maximum insulation.
- Cost-effective: EPS is a more cost-effective option than XPS, making it a popular choice for builders and homeowners alike. EPS is also easier to install, which can save you time and money on labour costs.
- Environmentally friendly: EPS is a more environmentally friendly option than XPS as it is 100% recyclable, and does not contain harmful CFCs (chlorofluorocarbons) or HCFCs (hydrochlorofluorocarbons).
- Resistance to moisture: EPS is also more resistant to moisture compared to XPS. This is important in a cavity closer, as any moisture that gets in can lead to dampness and mould.
- Easy to cut and shape: EPS is easy to cut and shape to fit any cavity closer, making it a more versatile material to work with compared to XPS.
In conclusion, when it comes to using materials in a cavity closer, EPS is the better option due to its superior insulation properties, cost-effectiveness, eco-friendliness, resistance to moisture, and ease of use. By choosing EPS, you can ensure that your property is well-insulated and protected from the elements, while also saving time and money on installation costs.
