Key Benefits of Polystyrene Insulation
When it comes to insulation, our EPS sheets offer several advantages that make them a strong choice for your projects:
Excellent Thermal Efficiency
Thanks to the closed-cell structure of EPS, our insulation sheets achieve outstanding U-values, significantly reducing energy loss. This helps maintain comfortable temperatures in residential and commercial properties, ultimately lowering energy bills.
Lightweight & Easy to Handle
Our insulation sheets are designed for ease of use. They are simple to cut, lift, and install, which speeds up the installation process on site. This feature is particularly beneficial for contractors aiming to optimise their workflow.
Versatile for Multiple Applications
Our EPS insulation can be used in walls, floors, roofs, and external insulation systems. This versatility ensures that you can find a suitable solution for a wide range of building projects.
Moisture & Rot Resistant
Ideal for damp-prone areas or under concrete slabs, our EPS sheets provide reliable moisture resistance, ensuring long-lasting performance in various environmental conditions.
Durable & Dimensionally Stable
Our insulation sheets maintain their performance over time without sagging, shrinking, or degrading, ensuring that your insulation solution lasts for years to come.
Cost-Effective & Long-Lasting
We offer high thermal performance at a competitive price point, making our insulation sheets an economical option with minimal maintenance required.
We understand that every project is unique. That's why we offer bespoke manufacturing on all insulation sheet orders, providing different thicknesses, densities, and board sizes to suit your exact specifications.
Frequently Asked Questions
How many insulation sheets do I need?
The number of insulation sheets required depends on several factors, including the area you need to insulate, the thickness of the sheets, and the insulation's R-value (thermal resistance). To determine the exact quantity, measure the total surface area to be insulated and divide it by the coverage area of each sheet. If you need assistance calculating your requirements, feel free to contact us at Polyscot Polystyrene Ltd, and we will be happy to help.
Are polystyrene insulation sheets energy efficient?
Yes, polystyrene insulation sheets are highly energy efficient. Their closed-cell structure provides excellent thermal insulation properties, resulting in outstanding U-values. This means they effectively reduce heat loss in buildings, contributing to lower energy bills and a more comfortable indoor environment.
Can EPS insulation be used for walls, floors, and roofs?
Absolutely! Expanded Polystyrene (EPS) insulation is versatile and suitable for a variety of applications. Our EPS insulation sheets can be installed in walls, floors, and roofs, making them an ideal choice for both new builds and renovation projects. Whether for solid wall insulation, floor insulation under concrete slabs, or roof insulation, our products deliver reliable performance across all applications.
Are polystyrene insulation sheets fire-resistant?
Polystyrene insulation sheets have a degree of fire resistance. However, they can be susceptible to ignition and can emit toxic fumes if they burn. To enhance safety, it's essential to follow building regulations and guidelines regarding fire safety. Additionally, we can provide information on fire-resistant coatings or treatments that can be applied to our polystyrene insulation products.
How do polystyrene insulation sheets compare to other insulation materials?
Polystyrene insulation sheets offer several advantages over other insulation materials, including:
- Cost-Effectiveness: EPS insulation is generally more affordable compared to materials like fibreglass or mineral wool, making it a budget-friendly choice for many projects.
- Thermal Performance: EPS provides excellent thermal insulation, often outperforming traditional materials in terms of U-value.
- Lightweight and Easy to Handle: Compared to heavier materials, EPS sheets are easier to transport and install, which can save time and labour costs on-site.
- Moisture Resistance: Unlike some insulation materials, EPS does not absorb water, ensuring long-lasting performance even in damp environments.
