Kingspan Insulation Board 6
Kingspan Group, headquartered in Ireland, is a well-known name across the UK construction sector. They make rigid insulation boards in Herefordshire that are distributed nationwide via specialist suppliers like us (Insulation Wholesale).
In our comprehensive catalogue, you’ll find Kingspan solutions that span everything from residential renovations to high-spec projects.
Builders, architects, and savvy homeowners trust Kingspan for their proven thermal efficiency technology, compliance with UK standards, and highly available supplies.
Key advantages of Kingspan insulation boards
Thermal efficiency + compact thickness
Across the UK, regulations demand high performance, and for builders looking to achieve minimal build-up, Kingspan boards like Kooltherm offer ideal options, with a low thermal conductivity of approximately 0.019 W/m·K, while being exceptionally thin.
If you are, for instance, trying to achieve Part L compliance without increasing wall or roof thickness, this Kingspan board is perfect.
Regulatory assurance and thermal certification
Many Kingspan products meet stringent fire and structural standards, such as NFPA 385 for Kooltherm. Products like OPTIM-R hold UK Technical Assessment (UKTA) and UK Declarations of Performance (DoP) certificates, offering you clarity and peace of mind.
Moisture control meets UK construction demands
In the UK’s often damp weather, Kingspan’s GreenGuard Series XPS boards present an ideal choice for resisting water absorption, while delivering an R-value of approximately 5.0 per inch.
This makes them the go-to option for basement walls and flat roofs, which are common features in UK architecture.
Reliable supply lines and delivery conditions
For local contracts, we offer insulated Kingspan sheets with accessible lead times (usually 2 to 5 working days) and comprehensive delivery practices and policies that cater to England and other regions (subject to accessibility).
A focus on sustainability
Kingspan has a programme called ‘Planet Passionate,’ which shows the company’s commitment to carbon reduction, recycling initiatives, and eco-conscious production.
Some of the progress shown on their website indicated they:
- Harvested 63.2 million litres of rainwater in 2024 and hope to hit a target of 100m annually by 2030.
- Achieved 30% on-site renewable energy generation in 2024.
- Recycled 1.1 billion PET bottles into its manufacturing processes.
- Reduced Scope 1 and 2 GHB emissions by 61% since 2020 (including acquisitions)
Kingspan insulation board product ranges
These are the main Kingspan insulation boards we offer:
- Kooltherm – This is a phenolic rigid board with high R-values per inch and an NFPA 385-compliant fire performance. It is ideal for walls and ceilings in both renovations and new-build scenarios. We offer K103, K106, K107, K108, K110, K112, K118, K15, and K5.
- GreenGuard – We stock the XPS series, including GG300, GG500, and GG700. This closed-cell insulation delivers an R-value of about 5.0 per inch and excellent moisture resistance. Excellent for foundations, below-grade walls, and external wall insulation.
- OPTIM-R – This innovative product leverages next-gen vacuum insulation, offering an exceptional level of thermal efficiency (around 0.007W/m·K) at astonishingly thin proportions. It is perfect for retrofitting buildings, limited-depth installations, and high-performance builds.
- Therma Series (TP10, TF70, TW55, TW50) – This is Kingspan’s high-performance line. It is slightly more fleshed out than the Kooltherm line and is best applied in fabric applications, including floors, walls, and roofs.
- PV (PIR) Flat Roof Series (Thermaroof TR24, TR26, TR27) – PIR boards are perfect for flat roofs, including torch-applied, fully adhered, or mechanically fixed membranes.
- Specialist Tapers (Thermataper TT44, TT46, TT47) – These are pre-cut tapered boards used to form positive falls on flat roofs. This helps with drainage and compliance with UK roofing regulations.

FAQ
What is Kingspan Insulation?
Kingspan Insulation is the overall brand name of multiple sub-brand names produced by the Kingspan Group. It is designed for energy efficiency and long-term performance, covering multiple applications, from commercial roofs to residential walls.
How to install Kingspan insulation between rafters?
The most effective method, especially in conversions, is to put in one layer of Kingspan between the rafters and a second layer, like insulated plasterboard, underneath. This is the ‘between and under’ method and is effective at minimizing thermal bridging and keeping roof spaces warm.
You will need to be precise when cutting, account for ventilation and airflow, seal gaps, and finish (with plasterboard, skim finish, etc.)
How to install Kingspan wall insulation?
Take the example of Kooltherm K118 insulated plasterboard. First, ensure the surfaces are cleaned, left to dry, and checked for flatness and structural soundness. Install panels with mechanical fixings instead of adhesives, especially on ceilings.
Before installation, conduct a survey to assess dampness rates, defects, and ventilation. Edges and corners can be tricky and require planning ahead to avoid inefficiencies and condensation problems.
How much is Kingspan insulation?
Prices vary based on product type, thickness, and quantity. Quick estimates on Insulation Wholesale show you should expect to pay about £35 to £45/m² for top-tier phenolic performance, £20 to £25/m² for efficient PIR and XPS insulation, and as low as £8 to £9/m² for thinner PIR options if you are on a tight budget.
These prices exclude VAT and delivery, which you should keep in mind when buying. We often do free deliveries for orders above £500.
Can you use Kingspan for loft insulation?
Yes, some of the products, such as Kingspan Kooltherm and Therma boards, are designed for pitched roof and loft insulation uses. They have excellent thermal properties and perform well in confined loft spaces.
