Welcome to the hub of 120mm insulation solutions on Insulation4less, your premier destination for high-performance insulation materials from revered vendors. Explore the myriad of options available, each uniquely designed to cater to diverse insulation needs across different environments and structures.

General Purpose Insulation Boards

Products like Celotex GA4000 and various offerings from Kingspan, such as Kooltherm K112 and K12 Framing Boards, serve a wide array of general insulation purposes, including wall and floor insulation. Crafted for robustness and durability, these boards commonly find their place in walls, floors, and roofs, ensuring a robust thermal performance and contributing significantly towards energy conservation and efficiency.

Practical Uses

  • Wall Insulation: Offering enhanced thermal resistance to ensure walls do not leak heat.
  • Floor Insulation: Ensuring that the ground’s cold doesn’t seep upwards, providing a warmer floor surface.

     

Guidance

Select general-purpose insulation boards for versatile applications. If your project involves insulating multiple areas (walls, roofs, floors), these boards offer a one-stop solution, albeit, specifics regarding thermal performance might drive your choice towards a particular product or brand.

Flat Roof Insulation Solutions

Dive into our range of flat roof insulation boards like Kingspan Thermaroof TR27 and TR26, as well as Celotex Crown-Up and Crown-Fix. These products are specifically engineered to provide unparalleled thermal performance in flat roof scenarios, ensuring minimise heat loss through the top of your buildings.

Practical Uses

  • Flat Roof Insulation: They provide a thermal barrier, preventing excessive heat loss through the roof.

     

Guidance

Focus on the thermal conductivity and compressive strength when selecting flat roof insulation. The durability and ability to withstand load are crucial factors for materials utilised in roof applications to ensure longevity and consistent performance.

Enhanced EPS Insulation

With products like Enhanced EPS from Jablite, this category thrives on offering products that not only provide effective thermal insulation but also ensure that they are lightweight and easy to handle.

Practical Uses

  • Wall and Floor Insulation: Particularly used where weight is a crucial factor, ensuring no significant load is added to the structure.

     

Guidance

Consider EPS for applications where ease of installation and lightness are key. Especially in scenarios where the structural load is a critical factor, EPS provides insulation without significantly impacting the weight distribution.

Rainscreen & Exterior Insulation

Incorporating insulation solutions like Rockwool Rainscreen Duo Slab and K-Roc Rainscreen Slab, this category provides insulation materials adept at navigating the challenges posed by external applications, offering both thermal insulation and weather resistance.

Practical Uses

  • External Wall Insulation: Protects the external façade, providing thermal insulation while also safeguarding against weather elements.

     

Guidance

When insulating external structures, consider the material’s weather resistance and durability alongside its insulative properties. A harmonious balance between these aspects ensures the longevity of the insulation material in an external environment.
