Doorframe Draught Insulation

thingiverse

An effective way to minimize heat loss due to drafts around a doorframe involves utilizing a specialized component. This component boasts a flat edge, which should be positioned against the door frame. The curved edge will come into contact with the door and flex, ensuring it remains tight without hindering door opening. To secure the component in place, you can employ a fixing method that suits your needs best. I opted for epoxy glue, which has proven effective without creating any mess. The component is designed to be 100mm tall, although this height can be adjusted to accommodate varying printer heights. Multiple components can be printed and stacked to achieve the desired full doorframe height. Simply layer them on top of each other. This design was specifically intended for interior doors, but it should work effectively with gaps ranging from 4 to 7mm. The component assumes a doorframe thickness of 35mm. To modify these parameters as needed, you can easily edit the Fusion 360 file included in this project. I printed this component using PLA and observed a significant reduction in heat loss. It has proven to be more effective than the insulation foam I previously used.
