Construction of Internal Door Frames

Before understanding the installation of internal door frames, it’s essential to know their structure and construction. Internal door frames are usually rectangular-shaped channels that form the frame of the door and the doorway. They are either made of wood, metal, or plastic. Wooden frames are popular in traditional homes as they provide a more natural look, whereas metal frames are more popular in modern homes as they provide a sleek and contemporary look. The frame consists of two side jambs and a head jamb, which form the top of the doorway, and a threshold or sill is attached to the bottom.


Installation of Internal Door Frames

The installation of internal door frames can be a daunting task, but with the right tools and instructions, it’s possible to do it yourself. The first step in installing a door frame is to measure the opening to ensure you get the correct type and size of the frame. Once you’ve bought the right size, the next step is to prepare the opening. This includes stripping the old frame and any debris and checking if the opening is level and square. The next step is to install the threshold and then attach the side jambs to the threshold using screws and ensure they are leveled. The head jamb is then installed, joining the two side jambs, and also needs to be leveled. Finally, the doorstop is installed to provide a channel for the door to close against.


Maintaining Internal Door Frames

Internal door frames require maintenance to ensure they remain in good condition and provide proper support to the doors attached. Maintenance includes the regular cleaning of the frames to avoid the buildup of dirt and debris. Moisture and dampness can also affect wooden door frames, causing them to rot, and it’s essential to check for any signs of rotting or decay regularly. Metal and plastic door frames are less susceptible to decay and rot but can get dented or scratched. It’s essential to repair any damages promptly to avoid further damage to the frames or doors attached.

Different types of doors require different types of frames, and it’s essential to choose the frame that is best suited for the door type. The material used in the frame can also affect its functionality and aesthetics. Wooden frames provide a natural look, but they are susceptible to rot and decay. Metal frames provide a sleek and contemporary look, but they can get dented or scratched. Plastic frames are less popular but are more durable and require less maintenance.
