Roller doors ("Sheet Doors"-USA) are usually constructed of corrugated steel. They evolved from cover window and door coverings. Other materials can be used (e.g.; transparent corrugated fibreglass) where strong impact resistance is not required. Corrugations give the door strength against impacts. A typical single car garage roller door has a preloaded spring inside the rolling mechanism. The spring reduces the effort required to open the door. Larger roller doors in commercial premises are not sprung (except USA) and use a manual pulley and chain system or a geared motor to raise and lower (roll up and roll down) the door. Roller doors cannot be effectively insulated.
I believe when making appointment for installment all charges should be discussed. In my case we payed in advance for installment of 2 garage door openers, however at time of installment we had to pay an additional 100.00 for 2 doors as there was no existing garage door openers previously...These are questions that should be asked at initial stage and not surprise customer at installment with additional fees.

Had a quick response to my call. thought I might have to wait a couple of days to coordinate their schedule and mine. To my surprise I received service in one and one half hours.
