While fibreglass isn’t quite as expensive as other materials, it offers fewer insulation properties. While rubber is a fantastic insulator, it’s more expensive. You should weigh these options carefully before making a final decision; some are able to pay more up front to reduce maintenance and repair costs in the future.
