Weatherize Homes With Our Door Sweeps

Door Sweep

Door sweeps are the small pieces of rubber or vinyl at the bottom of a door that effectively cover the gap where the door meets the bottom of the frame. This area is almost always built with a gap to allow the door to open and close smoothly. Contrary to its name, the door sweep doesn’t “sweep” anything. It acts as a buffer between the small gap and a home.

 

Not only that but it saves you money on energy as well. By acting as a layer of insulation and a seal between the air on the other side of the door and the inside controlled temperature air, it is effective at preventing  heat transfer or heat loss through air movement. Of course, it is even more effective when combined with a screen or storm door, because then less air is allowed to even come to the door in the first place.

 

It may also prevent heat loss if it is made of a good insulation material. Heat loss happens when heat is transferred between two materials when there is a difference in surface temperature. If the cold outside air touches the door sweep, and the door sweep is warmer than the air, the heat from the door sweep will be lost. If the door sweep is cooled and the material becomes colder, heat will be lost because the house is warmer. Rubber is a fairly good insulator for this purpose, which is why it is the material most often used in door sweeps.

 

The “brush” type of sweep is good for reducing air flow, but will readily transfer heat if temperatures are different – which is why a lot of modern outer facing doors are no longer sold with this type of sweep. If a door sweep gets worn and falls off you may ask yourself if you need to actually replace it for the customer. Do a simple test. If you feel air entering through the bottom of the door, then absolutely – your customer needs a door sweep. If not, and you cannot see the light from outside within the customers home, they may not need one. Though it certainly will never hurt to add one!
