Board Insulation | Foam Board | Insulation Board
Welcome to the Insulation Board category at Build4Less, where we offer a diverse range of insulation solutions to meet your building needs. Our collection includes products from top brands like Celotex, Kingspan, Recticel, Danosa, and more, each designed for specific insulation purposes.
General Purpose Board Insulation
These boards, such as the Celotex GA4000, are versatile and can be used in various applications, including floors, walls, and roofs. They provide excellent thermal insulation and are available in multiple thicknesses to suit different requirements.
Insulated Plasterboards
Products like Celotex PL4000 combine insulation and plasterboard, offering a two-in-one solution for walls. They are ideal for dry lining and provide both thermal insulation and a ready-to-decorate surface.
PIR Board Insulation
These boards, including Mannok Therm and Celotex XR4000, are known for their high thermal efficiency. They are suitable for a range of applications, including underfloor heating systems, and come in various thicknesses for different insulation levels.
Thermal Bridging Boards
Options like Celotex TB4000 are designed to address thermal bridging, improving energy efficiency in the window reveals and floor edges.
Specialty Insulation Boards
- For Roofs: Products like Kingspan Thermapitch TP10 are tailored for pitched roofs, providing high thermal performance.
- For Floors: Kingspan Thermafloor TF70 is ideal for floor insulation, offering moisture resistance and load-bearing capacity.
XPS Insulation: Danosa Danopren TR and Warmline XPS, made from extruded polystyrene, provide excellent moisture resistance and are suitable for basements and areas prone to dampness.
Cavity Wall Insulation
Boards such as Celotex CW4000 are designed for cavity wall applications, helping to reduce heat loss through walls.
Eco-Friendly Options
Products like Greenguard GG300 and Eco-versal prioritise environmental sustainability without compromising insulation quality.
Specialized Applications
- Rainscreen Boards: Kingspan Kooltherm K15 is an example of insulation designed for rainscreen cladding systems.
Flat Roof Boards: Kingspan Thermaroof series offers solutions specifically for flat roofs.
Choosing the Right Foam Board Insulation
Selecting the correct insulation board depends on several factors:
- Thermal Requirements: Higher R-values mean better insulation properties, which is crucial for minimizing heat loss.
- Space and Depth Availability: Some boards are thicker yet offer higher insulation, such as Celotex XR4000, which is suitable for areas where space is not an issue.
- Moisture Exposure: In damp areas, opt for moisture-resistant boards like XPS or specific PIR boards designed for damp conditions.
- Fire Performance: Consider the fire resistance of the insulation if installing in sensitive areas like escape routes or kitchens.
Our range at Build4Less ensures that you'll find the perfect insulation board solution for your project, whether it's a simple renovation or a complex new build.
