Frequently Asked Questions

Specifically engineered for structural ceiling (soffit insulation), Kooltherm K110 PLUS is a high-performance and impact-resistant insulation board that stands out for its low thermal conductivity of 0.019 W/mK. It is highly durable, moisture-resistant, and offers excellent fire protection. 

When installed correctly, Kingspan Kooltherm K110 PLUS will last indefinitely. 

Euroclass A1 means the material is considered entirely non-combustible by European standards. It is the highest possible classification. 

With an incredibly low thermal conductivity of 0.019 W/mK, Kooltherm K110 PLUS effectively reduces heat loss through structural ceilings, meaning your heating system doesn’t have to work as hard to maintain the temperature inside your property. This results in less harmful greenhouse gases and more energy cost savings.
