Count On Custom Exteriors To Help You Choose, Finance & Install Your Brand New Exterior Door.

In order to improve the energy performance of your home, it may be wise to consider a new exterior door. If maximum energy performance is your main goal, a thick, solid door can provide five times the insulating power of a glass door. Depending on the type of door you are looking to install, fiberglass may be the most energy efficient material for your door replacement.

The Science Behind Doors & Energy Efficiency

There are a few factors to consider when choosing a new exterior door:

  • R-Value - the capacity of a material to insulate. The higher the R-value, the better the insulation and the more energy you will save.

  • U-Value - also referred to as U-factor, it measures a door's resistance to heat loss and usually ranges from 0.20 to 1.20. The lower the number, the better the door is at keeping heat in.

  • Thermal Break - the material between the door and frame that is meant to reduce or prevent the flow of thermal energy between conductive materials.

  • Low-Emissivity Coatings - the ability of a material to radiate energy is called its emissivity. This coating is added to glass to lower the ultraviolet and infrared light that can pass through.

  • Low-Conductivity Gases - heat transfer occurs at a lower rate across materials of low thermal conductivity than across materials of high thermal conductivity. These gases are added between panes of glass to prevent heat transfer.

Financing Your New Door

Old doors can be very drafty - allowing a lot of flow of thermal energy. That’s why PACE programs make it so easy to finance the installation of a more energy efficient replacement door.

CaliforniaFIRST

In order to finance a door through CaliforniaFIRST it must first be a replacement for an existing door. From there, the biggest consideration to make is the replacement’s U-factor. For opaque doors the U-factor must be below 0.21, for less than ½-Lite doors the U-factor must be below 0.27 and the SHGC below 0.30 and for greater than ½-Lote doors the U-factor must be below 0.32 and the SHGC less than 0.30.

HERO

In order to finance a door through HERO it must first be a replacement for an existing door and NFRC Certified. From there, the biggest consideration to make is the replacement’s U-factor. For opaque doors the U-factor must be below 0.17, for less than ½-Lite doors the U-factor must be below 0.25 and the SHGC below 0.25 and for greater than ½-Lite doors the U-factor must be below 0.30 and the SHGC less than 0.25. In addition, HERO requires that your product meet Title 24 requirements and be installed based on the manufacturer’s instructions.
