Factors To Look For In Energy-efficient Folding Doors
The doors in your house do not only serve as plain entrance and exit points. They also play an important role in keeping all of you who live and enter your house secure. However, there are folding doors now which are installed with energy-saving features.
To choose a door with the best energy-saving features, consider the following factors:
1. U-factor This refers to the rate of heat that gets out of a building. The lower it is, the better.
2. R-factor This is the measurement of the level of insulation that the door will provide for the building at which it is installed. Unlike how you should look at the figures for the U-factor, you should choose a door that will give you a higher R-factor for this stands for better insulating capabilities.
3. VT or Visible Transmittance This is the measure of the visible light that is allowed to pass through the door. If you want more lighting, you should pick a door with a higher VT. If you want a dimmer room, choose a door with a lower VT.
4. SHGC or Solar Heat Gain Co-efficient This measures the ability of the door to block the heat coming from the sun. You should look for a door that has a lower SHGC because this means that it is better at blocking heat which will not add to your problem of ventilation.
5. Air leakage A better door would have a lower air leakage factor.
6. Condensation resistance This refers to how folding doors are able to cope with condensation formation underneath the surface of the door.
