Insulated garage doors will obviously give you a warmer garage if they are installed and specified correctly in the first place.
By their very nature insulated doors are always twin walled in construction and therefore also offer higher levels of panel strength whether in steel or aluminium. It is quite often the strength of the door panels which is more important and the insulation is a bonus. Panel strength also equates to higher security against attempted forced entry.
The highest levels of insulation come from the sectional type garage doors and the insulated roller doors generally do not have a specified ‘U’ value for insulation levels as they have too many areas where draughts and gaps are present. The best way to make sure an insulated roller door at least gives you a good level of insulation is to order the widest guides and a full hood cover to reduce the levels of air entering the garage. Some sectional garage door maufacturers now offer an upgrade on the standard frame mechanism to give even better levels of insulation for garages where it is important, i.e. rooms above, integral garage with rooms to the sides and back or where a lot of people nowadays are using the garage for a workshop, gym, office, playroom or other purpose.
Hormann offer the EPU40 and LPU40 as their insulated sectional door models and the EPU40 is 20mm thick whilst the LPU40 is 42mm thick. The EPU40 is practically as strong as the LPU40 with the same double skinned steel panels but just has 22mm less insulation foam inside the panel (EPU40 also has a smaller range of styles available). Carteck have recently introduced a range of stylish insulated side hinged garage doors, all made to measure with high quality hinges, locking and weatherseals and we think these offere excellent value for money for the specification. They are delivered with everything factory fitted including a fixing steel sub frame and fpr long term stability are head and shoulders above other types of side hinged doors.
