Why are manual insulated garage doors not available in a laminated woodgrain finish?
Due to the manufacturing process the lath that contains the locking bar is not able to be laminated.
Can they be upgraded to automation at a later date?
Our range of Gliderol single skin roller doors can be upgraded to automatic operation at a later date with the addition of the RW-1 Retrofit garage door operator. It is not possible to convert an insulated roller shutter garage door to operate by remote control at a later date.
How is the spring tension set?
To aid in operating the door by hand a roller door will have a torsion spring mounted within the barrel of the roll. Setting the tension will be detailed in the installation instructions supplied at the time of delivery or can be downloaded here.
If the door wants to rise or fall of its own accord or is very difficult to operate the likely cause is incorrect spring tension. In these instances always refer to the relevant manufacturer`s instructions for advice on how to make adjustments.
