Insulation4less.co.uk offers a comprehensive range of underfloor insulation products, catering to a variety of needs for thermal efficiency and comfort in residential and commercial buildings. Our underfloor insulation solutions are designed to reduce heat loss, improve energy efficiency, and enhance the comfort of your space.
PIR Insulation Boards
Celotex and Recticel brands lead our offering with their General Purpose PIR (Polyisocyanurate) Insulation Boards. Available in dimensions of 2.4m x 1.2m and varying in thicknesses from 12mm to 200mm, these boards provide a high-performance thermal solution for a range of flooring applications. The PIR boards are suited for both new builds and refurbishment projects where effective thermal insulation is crucial. They are also a popular choice for their ease of installation and structural strength.
XPS Insulation
For applications requiring enhanced moisture resistance and durability, our selection includes Danosa Danopren TR XPS Insulation and BASF Styrodur XPS. These Extruded Polystyrene (XPS) products offer robust insulation performance, especially in areas susceptible to moisture, such as basements and areas with high ground water levels.
EPS Insulation
EPS 70 is another key product within our underfloor insulation range. Expanded Polystyrene (EPS) is lightweight, versatile, and cost-effective, making it suitable for a variety of floor insulation applications where a balance between performance and budget is required.
Specialty Insulation Boards
Our catalogue also includes specialized solutions like Kingspan Thermafloor TF70 and Kingspan Kooltherm K103 Floorboards, which provide high thermal efficiency in a slimmer profile. These products are ideal when space is at a premium and are renowned for their exceptional compressive strength.
EcoTherm Eco-versal and Greenguard products also form part of our high-performance underfloor insulation, offering eco-friendly options with excellent thermal properties.
Laminate Insulation Boards
For hybrid insulation and structural applications, we have PIR-Plywood Laminate Insulation Boards. These are composite products that offer the benefits of insulation coupled with the convenience of a pre-laminated plywood top, streamlining the installation process for underfloor systems.
Considerations for Selection
When choosing the right underfloor insulation, consider the following:
- Thermal Performance: Check the R-value, which indicates the material's resistance to heat flow.
- Compressive Strength: Important for floor applications to withstand load-bearing requirements.
- Moisture Resistance: Essential in damp environments or on ground floors.
- Space Constraints: Thinner, high-performance insulation might be necessary for limited spaces.
- Sustainability: Eco-friendly options might be preferable for those seeking green building standards.
Underfloor insulation is a key component of a building's thermal envelope. Whether you're installing over a concrete slab, suspending floors, or retrofitting, our range of underfloor insulation products at Insulation4less.co.uk provides the quality, variety, and performance needed to meet the demands of your project.
