What is the Clear Opening Width and how do I work it out?
The clear opening width is the size of the gap any persons/objects can pass through freely when the door is opened to its full potential (most doors will usually only open to a 90-degree angle).
What is a U-Value and why does it matter for steel doors?
A u-value measures how efficiently a building element reduces heat loss.
