Jablite | Jablite Insulation Board

Jablite insulation is renowned for its high-quality, versatile range of Expanded Polystyrene (EPS) products, providing energy-efficient solutions suitable for a myriad of applications across the construction industry. As your go-to destination for insulation solutions, Insulation4less offers a substantial array of Jablite products, ensuring that each project you undertake benefits from top-tier insulation performance.

What is Jablite Insulation?

Jablite insulation is a high-performance, lightweight expanded polystyrene (EPS) insulation material designed for a wide range of applications, including floors, walls, roofs and foundations. Manufactured in the UK, Jablite products offer excellent thermal insulation, are easy to handle, and provide long-lasting energy efficiency for both residential and commercial buildings. Popular options like Jabfloor EPS70, EPS100, and Claymaster are available in multiple thicknesses to suit different project needs.

Jablite Claymaster Series

Purpose and Applications

Jablite Claymaster is a specialised series designed to prevent ground movement beneath architectural structures, providing foundational stability and insulative properties concurrently. Typically utilised in civil engineering projects, these EPS boards are indispensable in safeguarding buildings against the pressure and movement of surrounding clay soils, hence ensuring long-term structural integrity.

Variety in Thickness

Given the varying requirements and specifications of different projects, the Jablite Claymaster comes in a wide array of thicknesses, ranging from 25mm to 250mm. This diverse selection ensures that whether you're working on a project that requires lightweight insulating fill or heavy-duty foundational support, there’s a solution within the Claymaster series.

• 25mm to 75mm Thickness: Ideal for scenarios requiring light to moderate support and insulation, suitable for smaller structures or areas of minimal ground movement.
• 100mm to 175mm Thickness: This mid-range thickness provides a robust insulating layer and is well-suited for larger constructions or areas with notable soil activity.
• 200mm to 250mm Thickness: Offering optimal support and insulation, these thicknesses are apt for significant engineering projects where substantial ground support and thermal resistance are paramount.

Packaging Options

Jablite Claymaster products are available in various pack sizes to accommodate the scale and scope of your project. Smaller thickness boards generally come in larger packs (e.g., 25mm thickness comes in a pack of 24), while the denser, thicker options are available in smaller packs, facilitating ease of transport and handling on-site.

Enhanced EPS Insulation

The Enhanced EPS range utilises expanded polystyrene with added graphite to significantly boost thermal insulation capabilities, making these boards particularly effective for external wall applications. The lightweight nature of EPS ensures easy handling and installation without compromising performance, providing exceptional value.

Versatile Insulation Solution

Jablite Enhanced EPS sheets provide a versatile insulation solution, suitable for various applications including wall, floor, and roofing insulation. With its remarkable thermal performance, it safeguards buildings from thermal fluctuations, ensuring an energy-efficient, comfortable internal environment.

All Sizes for Your Specific Needs

Understanding the pivotal role of customisation and specificity in construction projects, Jablite Enhanced EPS sheets are available in all sizes, thereby ensuring you can achieve the precise fit for optimal insulation across diverse scenarios.

Selecting the Right Jablite Insulation Product

Understanding Your Project Requirements: When selecting from the Jablite category, it's crucial to thoroughly comprehend your project’s specific demands. Consider factors such as ground movement, required thermal resistance (R-value), and the physical constraints of your build.

Prioritise Thickness and Support: Choose the thickness of the EPS board based on the support and insulation required. A balance between structural stability (particularly for the Claymaster range) and efficient thermal performance should guide your selection.

Benefits of Jablite Insulation

• Excellent Thermal Performance – Jablite boards offer low thermal conductivity (as low as 0.030 W/mK), helping to reduce heat loss and energy bills.
• Lightweight & Easy to Install – Their lightweight nature makes handling and cutting quick and effortless, saving time on site.
• Cost-Effective – A budget-friendly insulation option without compromising performance.
• Durable & Long-Lasting – Resistant to moisture and rot, Jablite maintains its integrity over time.
• Environmentally Friendly – 100% recyclable and manufactured with minimal environmental impact.
• BBA Certified – Meets all necessary UK Building Regulations and standards for quality assurance.

Applications of Jablite Insulation

Jablite EPS boards are incredibly versatile and suitable for:

• Solid and Suspended Floors – Use Jabfloor EPS for ground floor insulation under concrete or timber.
• External Wall Insulation (EWI) – Claymaster EPS is ideal for insulating walls behind cladding or render.
• Loft & Roof Spaces – Lightweight and effective thermal barrier in attic conversions or cold lofts.
• Foundations & Below Ground – EPS boards are resistant to ground moisture and are commonly used below concrete slabs.
• Domestic, Commercial, and Industrial Projects – Suitable across new builds, extensions, and retrofits.

 Installation Tips

• Measure Accurately – Pre-plan and cut boards to fit snugly between joists, studs, or floor voids.
• Stagger Joints – For floor insulation, stagger the board joints to reduce thermal bridging.
• Fix Securely – Use mechanical fixings, insulation adhesives, or floor screed to secure in place based on the application.
• Combine with Vapour Barriers – For roof or wall insulation, use alongside membranes or barriers where required.
• Keep Dry – Store boards in a dry place and avoid prolonged exposure to UV before installation.
