Choosing the right insulation

Insulation’s ability to resist heat loss is measured with R-value. The higher the number, the more insulating it will be. But that doesn’t mean you need to go for the highest R-value when choosing steel garage doors. The right value for you and your business will depend on where you’re located, what the door is used for, and what building it will be fitted in. If you need any advice, our experts are happy to help.
