Creating an energy efficient and comfortable space starts with the right insulation. The 140mm insulation category at Insulation4less features a wide range of top-quality insulation materials from some of the most reputable vendors in the industry, providing solutions for various parts of a building structure. Navigating through the extensive product offerings, it's essential to understand the different types, their applications, and practical uses to select the most suitable insulation for your specific project.

 

General Purpose PIR Insulation Boards

Products such as Celotex GA4000 and IKO Enertherm ALU are versatile Polyisocyanurate (PIR) insulation boards which are applicable in multiple areas including walls, floors, and roofs. With remarkable thermal performance, these PIR boards are renowned for their ability to retain heat and enhance energy efficiency, providing a solution that meets strict building regulations. Opt for these insulations for a multi-purpose, high-performance option suitable for numerous applications.

 

Floor Insulation Solutions

In our selection, the Kingspan Thermafloor TF70 floor boards stand out for ensuring thermal integrity for ground floors. Floor insulation is pivotal to prevent heat loss and to maintain a stable temperature within a living or working space. These specialised boards aim to offer enhanced thermal resistance in floor spaces, ensuring a warm and comfortable environment, especially during colder months.

 

Flat Roof Insulation Boards

Including options like Kingspan Thermaroof TR27 and TR26, this sub-category provides products that are explicitly engineered for insulating flat roofs. Flat roof insulation is vital to manage the internal temperature of a building effectively and to prevent unwanted heat transfer between the exterior and interior. Choose these materials to ensure your flat roof constructions are adequately insulated, thus securing energy efficiency and durability.

 

Enhanced EPS Insulation

Enhanced Expanded Polystyrene (EPS) insulation, such as those offered by Jablite, offers a lightweight, moisture-resistant, and thermally efficient solution. Particularly applicable in wall insulations, including cavity walls, and underfloor heating systems, EPS insulation provides a blend of practicality and thermal performance. These materials are also frequently chosen for their ease of handling and installation.

 

Hybrid Reflective Insulation

For a high-performing, multi-foil solution, Actis Hybris panels provide a distinctive insulation choice. With a unique honeycomb structure, these panels offer excellent thermal performance and are often used in wall and roof applications. They provide a robust, yet light and flexible insulation solution that adapts to varied building requirements, notably in spaces where thickness and space are factors to consider.

 

Rock Mineral Wool Insulation

Knauf Rocksilk Flexible Slab is a type of rock mineral wool insulation, offering superb fire resistance, acoustic properties, and thermal performance. Particularly useful in walls, partitions, and floors, rock mineral wool is chosen for applications where fire safety and soundproofing are paramount, alongside thermal insulation.

 

 

Selecting The Right Product

 

Determine the Application Area: Before diving into product specifics, identify the primary area of application. Is it for walls, floors, roofs, or a combination? Some products, like general-purpose PIR insulation boards, are versatile and can be used in multiple areas, while others are specialized for specific applications.

Consider Thermal Performance: The primary purpose of insulation is to provide thermal resistance. Look at the R-value or U-value of the product. The higher the R-value, the better the material insulates. Products like Celotex GA4000 and IKO Enertherm ALU are known for their superior thermal performance.

Moisture Resistance: In areas prone to moisture, such as basements or ground floors, it's essential to choose insulation that resists moisture. Enhanced EPS insulation is a good choice for such applications.
