Welcome to the comprehensive overview of the 25mm Insulation Board category at Insulation4less, where we explore the versatile and essential world of insulation solutions from various eminent vendors such as Celotex, Recticel, Kingspan, Mannok, EcoTherm, Unilin, Ballytherm, and IKO PIR. These boards, all measuring a standard thickness of 25mm, are designed to serve myriad purposes across different areas of construction, ensuring optimal thermal performance, energy efficiency, and comfort within a building envelope.

General Purpose PIR Insulation Boards

Ceolotex and Recticel Boards

These brands offer reliable and versatile boards like the Celotex GA4000 and Recticel Eurothane GP, suitable for a range of applications, including roof, wall, and floor insulation. Optimal for both new build and refurbishment projects, these general-purpose boards are known for their excellent thermal performance and ease of installation.

EcoTherm Eco-versal Boards

Similarly, EcoTherm Eco-versal insulation boards are suitable for multiple applications, offering a universal solution for thermal insulation needs in varied building applications. These boards are recognized for their excellent compressive strength and long-term durability.

Boards By Application

Floor Insulation

Kingspan Thermafloor TF70 Boards provide a specialised solution for floor insulation, offering enhanced thermal resistance and ensuring minimal heat loss through floors, whether in domestic or commercial spaces.

Roof Insulation

Here we see offerings from Kingspan, such as Thermapitch TP10 and Thermaroof TR27 boards, which are engineered for pitched and flat roof insulation, respectively. They provide premium thermal performance, while also considering aspects like water and vapour resistance, ensuring longevity and stability of roofing systems.

Wall Insulation

Kingspan Thermawall TW55 boards are designed to cater to the specific requirements of steel and timber frame wall applications, delivering optimal thermal resistance, structural integrity, and moisture management.

Property Insulation Boards

IKO Enertherm ALU

Known for its unique aluminium-laminated surfaces, IKO Enertherm ALU not only provides excellent thermal insulation but also reflects radiant heat, creating a more stable and comfortable internal environment.

Unilin Thin-R

With a focus on achieving superior insulating properties in a slim profile, Unilin Thin-R boards are suitable for scenarios where space is a critical factor, ensuring you don't compromise on thermal efficiency in tight spaces.

Ballytherm

While specific details about Ballytherm boards require inquiry, they find their place in applications demanding reliable thermal performance and often cater to both general-purpose and specific insulation needs.

Guidance on Selection

Choosing the right insulation board involves considering factors such as the application area, desired thermal performance, compressive strength, and any specific attributes related to moisture, fire resistance, or reflectivity.

  • For diverse, non-specific applications, general-purpose boards like Celotex GA4000 or Recticel Eurothane GP often stand out as fitting choices.

     

  • When dealing with specialised insulation areas like roofs, walls, or floors, opting for products designed for those applications, such as Kingspan’s Thermafloor, Thermawall, or Thermapitch, will ensure better performance and suitability.

     

  • For projects where reflective insulation or space-saving is paramount, boards like IKO Enertherm ALU and Unilin Thin-R respectively offer tailored solutions.
