Applications:

• Ceilings: Provides enhanced insulation for suspended or dropped ceilings, reducing energy loss.
• Floors: Frequently used in underfloor heating systems, offering thermal resistance while supporting floor coverings.
• Walls: Fits seamlessly into cavity walls or external cladding systems, contributing to overall building energy efficiency.
• Cold Rooms: Used in small to medium cold storage facilities to ensure temperature stability.

Advantages:

• Enhanced thermal efficiency for a wide range of applications.
• Suitable for environments with moderate insulation needs.
• Balances cost and performance effectively.

3. 50mm Summit XPS

The 50mm Summit XPS board is the thickest and most robust option, designed for demanding insulation applications requiring maximum thermal performance.

• Thickness: 50mm
• Material: Extruded Polystyrene (XPS)
• Thermal Conductivity: 0.28 W/mK
• Compressive Strength: 310-360kpa
• Length: 1.8m – 8m
• Width: 600mm
• R-Value: 1.67 (Fully Aged)
• Water Absorption: 0.5% by volume

Applications:

• Roofs: Ideal for flat or inverted roofs where insulation must withstand weather exposure and foot traffic.
• Floors: Suitable for heavy-duty flooring systems, including industrial spaces and garages, as it provides superior insulation without compromising strength.
• Cavity Walls: Perfect for larger wall cavities in commercial buildings, ensuring excellent energy efficiency.
• Basements: Used in below-grade walls and floors to prevent heat loss and moisture ingress.
• Soundproofing: Due to its density and thickness, the 50mm board can also provide noise reduction, making it a dual-purpose solution for noisy environments.

Advantages:

• Exceptional thermal insulation for high-demand applications.
• Long-lasting performance in harsh conditions.
• Capable of handling high compressive loads.

How to Choose the Right Thickness

When deciding on the right thickness of Summit XPS, consider:

1. Application Requirements: For light-duty projects like ceilings or DIY insulation, 30mm boards may suffice. For areas needing robust insulation like roofs or floors, opt for the 50mm boards.
2. Available Space: Thicker boards offer better insulation but require more space. Evaluate your construction project’s spatial limitations.
3. Thermal Performance Needs: Higher R-values are achieved with thicker boards, making them suitable for colder climates or areas with high energy efficiency goals.
4. Budget: Thicker boards provide better performance but may have a higher initial cost. Balance your insulation goals with your budget constraints.

No matter the thickness you choose, Summit XPS guarantees exceptional insulation performance, durability, and ease of installation.

Key Features of Summit XPS

Summit XPS boards are engineered to provide high-performance insulation for various construction applications. Their unique properties make them a reliable choice for builders, architects, and homeowners alike. Here’s a detailed look at the features that set Summit XPS apart:

1. Superior Thermal Efficiency

Summit XPS boards deliver excellent insulation performance, thanks to their low thermal conductivity of 0.028 W/mK. This ensures minimal heat transfer, maintaining indoor temperatures and reducing the need for excessive heating or cooling. The high R-values across all thicknesses make it an effective solution for improving energy efficiency, leading to significant savings on utility bills.

2. Closed-Cell Structure for Moisture Resistance

The extruded polystyrene foam in Summit XPS boards features a closed-cell structure, which provides outstanding resistance to moisture absorption. This prevents water from compromising the insulation properties, ensuring long-term performance even in damp or humid environments. This characteristic also makes it ideal for applications in basements, roofs, and external walls.

3. High Compressive Strength

With a compressive strength of 300 kPa, it can withstand heavy loads without deformation. This makes them suitable for high-traffic areas such as floors, as well as structural applications in roofs and walls. The boards maintain their shape and insulation properties under pressure, ensuring durability and reliability in demanding conditions.

4. Lightweight and Easy to Install

Summit XPS boards are lightweight, making them easy to transport, handle, and install. They can be quickly cut and shaped to fit specific project requirements, saving time and effort during construction. This user-friendly quality makes them ideal for both professional contractors and DIY enthusiasts.

5. Long-Term Durability

Summit XPS is resistant to decay, rot, and pests, ensuring a long lifespan in various environments. Unlike some other insulation materials, it maintains its structural integrity and performance over time, even in extreme weather conditions. This durability translates to reduced maintenance costs and reliable insulation for decades.

6. Versatile Applications

The versatility of Summit XPS is one of its most appealing features. It can be used in ceilings, walls, floors, roofs, basements, and even cold storage facilities. Its adaptability makes it a one-stop solution for a wide range of insulation needs, from residential homes to commercial and industrial buildings.

7. Eco-Friendly Construction Solution

Summit XPS contributes to sustainable building practices by improving energy efficiency and reducing carbon footprints. By minimizing energy consumption for heating and cooling, it helps reduce greenhouse gas emissions.
