Insulated garage doors will obviously give you a warmer garage internally if they are installed and specified correctly in the first place…
By their very nature insulated garage doors are always twin walled in construction, with a foam core and therefore also offer far higher levels of door panel strength, whether in steel or aluminium. It is quite often this strength of the door panels which is more important and the insulation is just a bonus. Panel strength equates to higher security against attempted forced entry as well as the ability to add higher specification locking systems with the increased depth and strength in the door panels.
The highest levels of insulation come from the sectional and side hinged 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.
Some sectional garage door manufacturers 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. U values as low as 0.91 W/(m²·K) are possible.
Hormann offer their LPU42 and LPU67 as their insulated sectional door models. Carteck have their GSW40 insulated sectional doors. Carteck have also developed a range of stylish insulated side hinged garage doors over many years now, all made to measure with high quality hinges, locking and weatherseals and we think these offer excellent value for money for the specification. They are ideal for any single garage which is being used as another room to your home and requires additional weather sealing and insulation.
Insulated, double skinned garage doors are growing faster and faster in popularity for the modern UK home, often helping save money on energy bills but also providing peace of mind through enhanced security and greater longevity because of the overall integrity of the door.
