  • What is the difference between rebated and surface mounted seals?
    Rebated seals are hidden in rebates, making them ideal for doors which can be modified which also want to look as unaltered as possible.Surface mounted seals are easier to install and simply fix onto the exterior part of the door. Oftentimes they are more expensive, however, although are appealing due to the quick install time, which could also save you money.
