Providing separation between the outside elements and the internal environment, the building envelope’s impact on energy efficiency is critical. The doors you choose for loading docks and bays not only contribute to the overall integrity of the building envelope and the energy efficiency of the structure. The right commercial garage doors can also increase the comfort and productivity of your employees. By preventing thermal transfer from the exterior to the interior, insulated overhead doors decrease energy consumption. The solid construction also reduces noise, further contributing to a more comfortable working environment in the building.
