Welcome to the Celotex category on Build4Less, where we provide a comprehensive range of Celotex insulation solutions suitable for a variety of applications. Celotex is renowned for its high-quality PIR (Polyisocyanurate) insulation boards, offering exceptional thermal performance for both commercial and residential buildings.
General Purpose PIR Insulation Boards
Our Celotex GA4000 series is the cornerstone of general-purpose insulation, perfect for floors, walls, and roofs. These boards come in standard dimensions of 2.4m x 1.2m, with thicknesses ranging from 12mm to 100mm to suit different insulation requirements. These boards are versatile and can be used in a multitude of settings, providing a reliable barrier against heat loss.
Insulated Plasterboards
For those looking to combine insulation with an internal finish, Celotex PL4000 Insulated Plasterboards are the ideal choice. These composite products feature PIR insulation bonded to plasterboard, streamlining installation by combining two steps into one. Available in various thicknesses, they are especially suited for internal walls and loft conversions, where space is at a premium.
Thermal Bridging Boards
Celotex TB4000 Thermal Bridging Boards are designed to address thermal bridging - a common issue in buildings where heat is transferred across an uninsulated component. Ranging from 12mm to 40mm in thickness, these boards are installed in critical heat loss areas such as window reveals and junctions, enhancing the overall thermal performance of the building envelope.
High Thickness Insulation Boards
For projects requiring high levels of insulation, Celotex XR4000 Insulation Boards are the heavyweight contenders in our lineup. These come in greater thicknesses from 110mm to 200mm, providing enhanced U-values and energy efficiency for areas that require superior insulation, like under heavy-duty floors or in advanced roofing systems.
Specialized Applications
Additionally, we offer specialised products like Celotex CW4000 Cavity Wall Boards and Celotex PL4000 Insulated Plasterboard with varied thicknesses for cavity walls and internal lining applications, respectively. These solutions are designed to meet the specific needs of modern construction techniques and building regulations.
Choosing the right Celotex product depends on the specific requirements of your project. Consider the area of application, desired thermal performance (U-values), and any building regulations that may apply. With a range of thicknesses and specialised options, the Celotex category on Build4Less provides the versatility and performance needed to tackle any insulation challenge.
