Welcome to the Flat Roof Insulation category on Build4Less! As experts in the field, we're here to guide you through the selection of flat roof insulation solutions suitable for a variety of applications.

Composite Insulated Roof Panels

333 Box Profile Composite Insulated Roof Panels (Goosewing Grey) are an all-in-one solution, combining durability, insulation, and a sleek finish. Ideal for commercial and industrial buildings, these panels offer robust weather protection and thermal efficiency.

SuperFOIL Insulation Products

SuperFOIL offers a comprehensive range of multi-layer foil insulation products suitable for various applications:

  1. Foil Tapes: These are essential for sealing joints and edges of insulation sheets to maintain continuity of the insulation layer.
  2. Foil Insulation Rolls: Available in different thicknesses, these rolls provide a high-performance insulation layer, reflecting radiant heat and providing a vapour control layer.
  3. Pipe Wraps and General Purpose Wraps: Specifically designed for wrapping around piping or for smaller applications, providing targeted insulation to reduce heat loss.

     

Actis Insulation

Actis Boost'R Hybrid Reflective Breather Membrane combines insulation with a reflective layer, ideal for use in conjunction with other insulation materials to enhance overall thermal performance.

Sheepwool Insulation

Sheepwool offers natural, breathable insulation products like Loose Wool and Window and Door Filler. These are perfect for environmentally-conscious projects requiring a sustainable, yet effective insulation solution.

Kingspan Thermataper

Kingspan Thermataper TT47 and TT46 are tapered insulation solutions, designed to provide a fall on flat roofs, ensuring efficient drainage and thermal performance.

Selecting the Right Product

When selecting the appropriate flat roof insulation, consider:

  • Thermal Requirements: Ensure the product meets the thermal resistance needed for your project.
  • Application Area: Consider the size and specifics of the area being insulated. Some products are better suited for large open areas, while others are designed for targeted applications.
  • Building Regulations: Ensure compliance with local building regulations and standards.
