Thermal Insulation
Create energy-efficient homes and buildings with thermal insulation
Thermal insulation is a core component of a building’s construction and can be found in the roof, floor, ceiling and wall elements. Mineral wool thermal insulation (also known as glass wool or stone wool) is thermal insulation that comes in many forms, including rolls, batts, pipe sections and slabs.
Mineral wool thermal insulation benefits at a glance:
- Thermal efficiency
- Energy efficiency
- Able to meet U-value requirements on a variety of projects
- Enhance indoor comfort
The benefits of thermal insulation
Depending on your needs, mineral wool can help reduce heat loss in cavity walls, lofts, partitions, ducts and pipes. Let’s look at the core elements.
Thermal insulation can help to reduce heat loss in the winter and heat gain in the summer, which can lead to less energy being needed to sustain the desired temperature. Mineral wool insulation does this by slowing heat loss transfer.
Using thermal insulation helps designers, builders and contractors to meet thermal performance or U‑value requirements in building regulation or certification systems. To help you calculate yours, you can use the Isover U-Value calculator here.
Using thermal insulation can help you achieve a more consistent temperature . Isover UK products have met the standard to be accredited to Eurofins Indoor Air Comfort® Gold Certification - the highest accreditation for indoor air quality.
