Insulation boards

Welcome to our Floor Insulation category at Build4Less Here, you'll find a comprehensive range of floor insulation solutions catering to various needs and preferences. Let's explore the different types of floor insulation available and guide you in selecting the perfect fit for your project.

Polyisocyanurate (PIR) Insulation Boards

Our PIR Insulation Boards, such as Celotex GA4000, TB4000, XR4000, and Mannok Therm PIR, are renowned for their thermal efficiency. These boards are versatile, making them suitable for multiple applications, including underfloor heating systems. Their rigid structure provides excellent load-bearing capacity, ideal for floors that experience regular foot traffic.

Expanded Polystyrene (EPS) Insulation

EPS 70 offers a cost-effective insulation solution with good thermal properties. This lightweight material is easy to handle and install, making it a popular choice for DIY enthusiasts and professionals alike. It's particularly effective in areas where moisture resistance and durability are key considerations.

Kingspan Insulation Boards

Kingspan Thermafloor TF70 and Kooltherm K103 boards are premium options known for their exceptional thermal performance. These boards are thinner than traditional insulation materials, providing more space without compromising on insulation quality.

Specialized Acoustic Insulation

For those looking to reduce noise transmission, our Karma Acoustilay and Regupol Quietlay products are ideal. They are specifically designed to enhance acoustic insulation in floors, making them perfect for apartments, studios, and offices.

Extruded Polystyrene (XPS) Insulation

Products like Danosa Danopren TR XPS and BASF Styrodur XPS are excellent for high-load applications. These insulations offer superior moisture resistance and strength, ideal for basements and areas prone to dampness.

Mineral Wool Insulation

Knauf OmniFit Slabs and Rolls provide robust thermal and acoustic insulation. These are versatile and can be used in various applications, including floor insulation. They are particularly useful in environmentally conscious projects due to their sustainable composition.

Advanced Insulation Solutions

For cutting-edge insulation needs, Spacetherm Blanket and Eco-versal offer high-performance options. These materials are designed for maximum efficiency in thermal insulation, making them suitable for high-specification projects.

Accessories

We also offer essential accessories like Foil Tape to ensure a complete and effective insulation installation.

Choosing the Right Floor Insulation

  • Thermal Performance: Consider the U-value you need to achieve and choose a product that meets these requirements.
  • Application Area: For underfloor heating, opt for high compressive strength products like PIR boards. For noise-sensitive areas, go for acoustic insulation.
  • Environmental Conditions: In damp areas, choose moisture-resistant options like XPS.
  • Space Constraints: If space is limited, consider thinner, high-performance options like Kingspan boards.

     

Remember, our range covers various sizes and thicknesses to cater to different project scales and requirements.
