100mm Insulation
100mm insulation is material such as mineral wool, fibreglass and foam that is 100 millimetres (4 inches) thick. It is commonly used in buildings to reduce heat transfer between the interior and exterior of the structure. This is not limited to walls, floors, roofs, pipes and other equipment to prevent heat loss or gain. With that said, this 100mm thick insulation can also provide sound insulation in noisy environments, including near airports or busy roads, reducing the amount of noise entering a building.
With high thermal resistance, this 100mm insulation will help keep indoor spaces at a comfortable temperature regardless of the outdoor weather conditions. This can help contribute to energy efficiency as heating and cooling systems do not need to work as hard to maintain the desired temperature. So, don't wait to contact our excellent customer service team for advice and a no-obligation free quote. We'll provide fast UK delivery to ensure you can insulate your property promptly.
