Indispensable to an array of construction projects, Foil Backed Insulation Boards serve to enhance thermal efficiency, ensuring that structures are adeptly shielded from the often-harsh embrace of external temperatures. In the diverse assortment available at Insulation4Less, you’ll discover an array of options, each meticulously designed to cater to various application needs within the domains of roofing, flooring, and wall installations, and more.

Pioneering Performance with PIR Insulation Boards

Celotex and Recticel: Renowned for their steadfast performance and resilient thermal capabilities, PIR boards from brands like Celotex and Recticel ensure multi-faceted utility across numerous structural elements, including walls, floors, and roofs. Their varied thickness, as observed in offerings like the Celotex GA4000 and Recticel Eurothane GP, provides adaptable solutions, thereby addressing varied thermal requirements and building specifications.

Luxuriating in the Robustness of Phenolic Foam Insulation

Kingspan: A name often synonymous with formidable quality in insulation, they presents a range that predominantly utilises phenolic foam, notorious for its low thermal conductivity and fire-resistant properties. Products like Kingspan Thermawall TW50 and Kingspan Kooltherm K112 offer solutions tailored for distinct applications including cavity wall insulation and framing board insulation, respectively, each ensuring a robust defence against thermal bridging and heat loss.

Exemplifying Versatility with Multi-Purpose Insulation Boards

EcoTherm: EcoTherm Eco-versal Insulation Boards pronounce themselves as a quintessential choice for a wide range of applications, furnishing both builders and DIY enthusiasts with a product that vows steadfast thermal performance across varied building elements, owing to its universality in application.

Steadfast & Resilient Insulation with Specific Purposed Boards

Mannok and Unilin: With Mannok offering a generalised utility, and Unilin putting forth specialised PIR boards, both brands curate products that extend resilient and steadfast thermal performance. Ensuring that the structures are not only thermally well-guarded but also, that they adhere to regulatory compliance.

Guiding Your Choice in Foil Backed Insulation Boards

Deliberating Thickness and R-Values

When selecting the appropriate insulation board, consider the thickness and the resultant R-value, ensuring that your choice adheres to the building’s thermal requirements and compliance standards.

Purpose-Oriented Selection

From roofs (like with Kingspan Thermapitch TP10) to floors (exemplified by Kingspan Thermafloor TF70) and walls (such as Kingspan Thermawall TW50), discern the specific utility of each board, ensuring it aligns with your project’s demands.
