What is EcoTherm Insulation?

EcoTherm is one of the leading manufacturers of premium quality PIR insulation boards. It manufactures a range of boards that are designed for specific purposes; EcoTherm Eco-Versal, Eco-Torch, and Eco-Cavity boards are tailor-made for different insulation needs.

No matter which EcoTherm product you choose, you can expect a fibre-free rigid polyisocyanurate PIR board with a low lambda value. Most EcoTherm boards have a lambda value of 0.022 W/mK, meaning that they’re highly thermally efficient.

EcoTherm Insulation Benefits

  • Efficient Thermal Insulation: Utilises polyisocyanurate (PIR) for high thermal efficiency.
  • Durable Construction: Offers compressive strength with a fibre-free rigid PIR core.
  • Low Moisture Absorption Capacity: Essential for durability and consistent thermal properties. 
  • New Build Applications: Suitable for new construction projects.
  • Upgrading Existing Builds: Ideal for upgrading the thermal performance of existing structures.
  • Tailor-Made Solutions: Options include Eco-Versal, Eco-Cavity, and Eco-Torch.

EcoTherm Insulation Applications

Ecotherm's insulation boards are tailored to different applications, allowing for a versatile approach to insulating various parts of a building.

EcoTherm can be utilised as: 

Here's how different products work in unique applications:

Eco-Versal (2400mm x 1200mm): This general-purpose insulation board is adaptable and can be used in various applications including floors, walls, and roofs. Its size and characteristics make it suitable for a wide range of construction scenarios, from new builds to retrofit projects.

Eco-Cavity (450mm x 1200mm): Specifically designed for cavity wall insulation, Eco-Cavity provides a targeted solution for insulating the gaps between wall layers. Its size and construction are optimized to fit within standard wall cavities, enhancing thermal efficiency without adding bulk.

Eco-Torch (1200mm x 600mm): Tailored for roofing applications, Eco-Torch offers a specialized approach to insulating flat roofs. Its construction allows for easy installation and ensures excellent thermal performance, making it a preferred choice for both residential and commercial roofing projects. 

EcoTherm Insulation Thickness

We stock EcoTherm Eco-Versal, Eco-Cavity and Eco-Torch products. Our customers can purchase these products in a range of thicknesses between 25mms and 150mm. Different thicknesses are better for different purposes. The thicker the insulation, the lower the thermal value of the buildup.

Follow this EcoTherm thickness guide for EcoTherm’s Eco-Versal products for general applications.

●     25mm - 40mm boards can overcome localised thermal bridging

●     50mm - 100mm boards are general purpose and can be used as floor, wall, or roof insulation

●     110mm - 150mm boards are ideal for cut-to-fit applications between rafters or joists, floors, and flat roofs

EcoTherm insulation data sheets contain further information about each product. You can find the data sheet for each product listed under ‘Technical Downloads’ on each product page.

EcoTherm Installation Essentials

  • Avoid installing fixings within a 50mm perimeter of the board when using mechanical fixing methods.
  • All flat roofs require a vapour control layer. Follow the guidelines outlined in BS 6229:2003.
  • To ensure a secure and tight fit, stagger the placement of the boards and tape the joints as specified.
  • Determine the appropriate number of fixings required for your project by referring to BS 6399-2:1997 or Euro Code 1:EN1991-1-4.

For a thorough step-by-step installation guide and other tips and tricks, please refer to our Celotex Installation Guide. While this guide specifies Celotex solely, it's important to note that Ecotherm and Celotex are essentially the same product and will give the same U-values for a given thickness.

Frequently Asked EcoTherm Insulation Board Questions

Is EcoTherm Insulation Sustainable? 

EcoTherm is devoted to being eco-friendly and curbing energy consumption. Their products make for one of the best solutions in mitigating heat loss from buildings and promote a 'fabric first' approach to construction.

Ecotherm insulation boards are constructed with rigid polyisocyanurate foam (PIR). This highly efficient insulating material can help to minimise the energy costs and greenhouse gas emissions that come with cooling and heating buildings. 

Despite its impressive insulation properties, PIR is not the most sustainable option due to the fact that it is produced from non-renewable fossil fuels and is difficult to recycle or biodegrade.

That being said, EcoTherm insulation boards are designed to last for the lifetime of a building, which can help reduce the need for future energy-intensive renovations or replacements. 

Moreover, EcoTherm insulation boards can help improve the energy efficiency of buildings, which can contribute to a reduction in greenhouse gas emissions over the long term.

Overall, while EcoTherm insulation boards may not be considered sustainable in the strictest sense, they can still play an important role in improving the energy efficiency of buildings and reducing their environmental impact.

Are EcoTherm Insulation Boards Combustible?

The Euroclass scale measures the combustibility of construction materials. Classifications are written in letters and numbers. The best grade is A1, which means that the material is non-combustible. The lowest rating that a material can be awarded is F. Materials that are graded F are combustible.

Materials undergo up to five different tests to gain a fire performance classification. There are additional tests for smoke production. 

Products that achieve an S1 classification produce little or no smoke, whereas products that gain an S3 grade will produce substantial smoke.

EcoTherm Eco-Versal, Eco-Torch, and Eco-Cavity insulation boards have a Euroclass rating of F. We recommend placing additional layers of fireproofing material on top of EcoTherm roof insulation to improve the fire-retardant properties of the buildup. 

You can put reinforcement layers, carrier membranes, and waterproof materials on the top of EcoTherm boards. You should always consult an expert when deciding on products intended to provide fire protection.

Is EcoTherm Insulation Water Resistant?

EcoTherm roof insulation is not water-resistant. We recommend using additional materials to protect EcoTherm cavity wall insulation, roof insulation, and floor insulation from moisture.

People who want to use EcoTherm products to insulate their floor should use a Damp Proof Membrane (DPM) to prevent water damage. 

Products that are laid against a concrete slab should be overlaid with a protective membrane. The membrane should have a minimum of 500 gauge.
