GreenGuard GG25-LG XPS Insulation Board
Low GWP formula Type IV XPS, min comp strength of 25 psi & 5 R-value/inchAt Kingspan Insulation, we are your full spectrum insulation solutions provider, dedicated to empowering your projects with the highest quality of innovative products.
We take pride in delivering a diverse portfolio of products that seamlessly combine cutting-edge technology and tested performance, which help to reduce buildings’ operational carbon. From ultra-thin vacuum insulation panels that optimise space without compromising thermal efficiency, to rigid board insulation and more traditional mineral fibre batts.
As part of our Planet Passionate initiative, we aim to make significant advances in the sustainability of our business operations and our products. We have now taken a step forward in driving down the embodied carbon of our insulation materials, by harnessing the benefits of biological processes. Our new insulation products put bio-based raw materials, such as hemp, at their core and combine lower embodied carbon, than our historical products, with tested thermal properties.
Our insulation boards and building services insulation products deliver market leading performance across a range of areas, allowing specifiers and installers to meet energy performance and sustainability targets even in challenging spaces.
At the core of our commitment lies a passion for brilliance and customer excellence. Our team of experts collaborates closely with architects, engineers, builders, and homeowners to understand their specific challenges and deliver tailored solutions that exceed expectations.
With an aged thermal conductivity of between 0.019 - 0.022 W/mK, it offers the thinnest solution of any commonly available insulation to achieve desired U-values for roof, wall and floor applications.


Offering a thermal conductivity as low as 0.007 W/m.K and a compressive strength ≥ 150 kPa it can provide a slim solution for problem areas in roof and floor applications.
With an R–value of 5.0 per inch of thickness and a compressive strength that typically exceeds (172)kPa /(25psi) it is suitable for heavy duty floor and roof applications and commercial, industrial or cold store flooring.
