Kingspan Insulation Board

(98 Products)

Kingspan insulation boards are crafted to boast some of the industry's lowest thermal conductivity values, owing to their innovative material selection and manufacturing processes. By prioritising low thermal conductivity in their insulation boards, Kingspan ensures that their solutions effectively combat heat transfer. This not only helps maintain comfortable indoor temperatures but also leads to significant energy savings in heating and cooling, making Kingspan insulation a vital component in cost-effective and energy-efficient building solutions.

What Are Kingspan Insulation Boards?

Kingspan, a leader in the insulation industry, has made significant strides in advancing thermal technology and promoting sustainable building practices. The company's commitment to these areas is vividly demonstrated through its range of high-performance insulation boards

Kingspan leverages state-of-the-art material sciences to develop its range of insulation products. These materials, including phenolic foam, polyisocyanurate (PIR), and extruded polystyrene (XPS), are selected for their outstanding insulative properties characterised by very low thermal conductivity. This ensures optimal performance in a variety of building applications.

Kingspan Insulation Board Range

  • Kooltherm Series: This series features phenolic foam, renowned for its exceptionally low thermal conductivity, which ranges from 0.018 W/mK to 0.023 W/mK depending on the product. This variance allows for optimal customisation based on specific insulation needs and environmental conditions.
  • Therma Series: Comprising PIR foam, the Therma series offers a robust combination of thermal resistance, moisture resistance, and durability with conductivity values typically between 0.022 and 0.027 W/mK.
  • Greenguard Series: Utilising XPS, these boards are suited for environments prone to moisture and mechanical loads, offering thermal conductivity figures typically from 0.028 to 0.036 W/mK.

Kingspan Insulation Boards Features and Benefits

  • High Thermal Performance: Low thermal conductivity values contribute to significant energy cost savings.
  • Moisture Resistance: Provides excellent resistance to moisture ingress, maintaining its insulative properties in diverse conditions.
  • Fire Performance: Compliant with international fire safety standards, ensuring enhanced protection for buildings.
  • Eco-Friendly: Manufactured with a focus on sustainability, with options for recycled content and low global warming potential (GWP) materials.
  • Durability: Resilient against decay, providing long-lasting insulation performance.

Kingspan Insulation Board Applications

  • Kooltherm Series: Premium performance rigid thermoset phenolic insulation boards suitable for roofs, walls, and floors.
  • Therma Series: High-performance rigid thermoset polyisocyanurate (PIR) insulation boards designed for a range of applications including pitched roofs and cavity walls.
  • Greenguard: Extruded polystyrene (XPS) insulation designed for heavy-duty applications such as load-bearing floors or below-ground walls.

  • Cutting: Boards can be easily cut to size with standard tools.
  • Fixing: Depending on the application, boards can be mechanically fixed or adhered using appropriate adhesives.
  • Sealing: Use appropriate sealing materials to ensure airtight and moisture-resistant installations.

Kingspan Insulation Boards Technical Specifications

  • Thermal Conductivity: Ranges from 0.018 W/mK to 0.036 W/mK depending on the product line.
  • Sizes: Available in a variety of thicknesses and dimensions to meet specific needs.
  • Compliance: Meets or exceeds industry standards such as ASTM, ISO, and EN.

Frequently Asked Kingspan Insulation Board Questions

Are Kingspan Insulation Boards Fireproof?

Before buying any type of insulation, we recommend you check the Euroclass rating before committing to purchase. Every single insulation board has a Euroclass rating. Euroclass ratings will tell you how flammable the board is. The scale covers a wide range of options, from A1 (non-combustible) all the way to F (combustible).

The Kingspan Kooltherm range is made from phenolic insulation which benefits thermal conductivity. When phenolic insulation is exposed to heat, a process called pyrolysis (thermal decomposition) begins. A black mark appears on the part of the board that is exposed to heat and hot combustible gases become airborne. Despite this, some of the Kingspan Kooltherm boards can achieve a Euroclass rating of B, which is the best performance that a combustible material can achieve.

The Kingspan Therma range is made from PIR insulation. Like boards in the Kooltherm range, some Kingspan Therma boards offer better fire-resistant qualities than others. Kingspan cavity wall insulation, floor insulation, and loft insulation all have different properties. 

Kingspan notes that all its Therma boards have ‘properties which can limit their contribution to fire development’ and that ‘the products will self-extinguish when the flame source is removed.’

A poor Euroclass rating should not deter you. You should focus on the overall value of the build-up of materials that you use. You can install other materials alongside Kingspan insulation boards to improve the overall fire rating. 

Are Kingspan Insulation Boards Waterproof?

Phenolic Kingspan insulation boards only absorb around 2% of moisture. They are designed for both residential and commercial use. When you choose boards from the Kooltherm range, you can expect excellent thermal protection and water resistance.

Like Kingspan phenolic boards, Kingspan PIR Therma panels have a closed-cell structure and are resistant to moisture. 

Can You Paint Kingspan Insulation Boards?

There are lots of benefits to choosing rigid boards instead of rolls or batts. One of them is that you can apply paint directly to the board.

You can only paint foil-faced insulation if you prepare the board, however. Foil facings are nonporous, which means that they will not hold the paint. If you pre-treat the facing with galvanised metal etching primer, you can expect a better result.

Always consult with a professional before painting a rigid insulation board. The painting process might involve dangerous chemicals that are better left to the professionals.
