Introducing Kingspan GreenGuard GG300 (Formerly known as Kingspan Styrozone), your premier choice for rigid extruded polystyrene (XPS) insulation. With its remarkable compressive strength, XPS is the preferred solution for a range of specialised applications, including inverted roofs, basements, car park decks, and heavy-duty commercial, industrial, and cold store flooring.
Designed to excel in these applications, GreenGuard GG300 boasts impressively low thermal conductivities, as low as 0.034 W/m·K. This insulation material is the top pick for ensuring superior thermal performance in inverted roofs, basements, car park decks, and the rigorous demands of heavy-duty commercial, industrial, and cold store flooring.

What is XPS insulation?
XPS insulation, short for extruded polystyrene insulation, is crafted using an extrusion technique, resulting in a closed-cell rigid insulation material. This inherent closed-cell structure imparts essential compressive strength, rendering it an ideal choice for specialized applications like heavy-duty flooring, car park decks, and inverted roofs.
What is the U-value of Kingspan insulation?
U-value is the inverse of the sum of the thermal resistances of the layers that make up an entire building element – for example, a roof, wall or floor. The lower the U-value, the better insulated the building element. It also includes adjustments for any fixings or air gaps. Therefore, our insulation doesn't have a U-value on its own.
Our technical team can complete a U-value calculation for your project if you have a few specific details you can share about it. Just follow the link at the bottom of the page.

Help with my new garage roof!
Trade Warehouse could not have been more helpful. They very patiently guided a roofing newbie through all of the stuff I would need to do the job and provided helpful tips along the way. It's rare to find a company offering such a fantastic level of customer service as standard. I would highly recommend them and will certainly use them again.

My contractor (Charlie Keep) recommended you to me so I could order the materials online for delivery direct to my home. These were for a project to construct a Garden Storage Area. The materials were perfect and the whole process was simple and slick with materials delivered on time and very well packaged. Charlie has since completed the project & I am very happy with the outcome.

Right product, right price, right delivery.
Right product, right price, right delivery. Sure, it was only one length of cast iron guttering but they took the order seriously, packed it well and kept me updated on delivery. And when I opened the very good packaging I found it was exactly what I had wanted. How can you do better!!
