You can have an entry door that brings in natural light and still keeps your home comfortable. The key is choosing the right glass and materials, then making sure the door is installed level, square, and sealed. A beautiful door that leaks air will cost you in comfort and in energy bills.
At Progressive Insulation & Windows, we have helped homeowners protect the comfort and efficiency of their homes since 1978. Here is what Canoga Park homeowners should consider when selecting a new entry door.
Why Does an Entry Door Affect Energy Efficiency?
An entry door is a large opening in your home’s exterior, and it is used every day. Gaps around the frame, worn seals, and a poor fit can let conditioned air escape and outside air in. Because air leaks are a leading cause of high heating and cooling bills, even a single drafty door can make a noticeable difference.
Glass also plays a role. Sun exposure can heat up an entryway, especially during the warm summer months common in the San Fernando Valley.
How Do You Add Light Without Adding Heat?
Many homeowners want a door with decorative glass, sidelites, or a transom window above the door. These features can brighten a dark entry, and they can be done in an energy-conscious way. Consider these points:
- Ask about Low E glass options, which are designed to reduce how much solar heat passes through glass
- Consider the amount and placement of glass, since more glass means more exposure to the sun
- Look at the direction your entry faces, because west-facing doors take in the most afternoon heat
- Choose glass styles that provide light and privacy at the same time
You can browse the styles we offer, from entry doors to French and sliding doors, on our doors page.
Does the Door Material Matter?
Yes. Materials differ in how they handle heat, durability, and upkeep. Just as frame materials with low thermal conductivity help windows perform better, a door’s construction affects how well it insulates. When you meet with a door specialist, ask how the door is built, how it performs in direct sun, and how much maintenance it will need over time.
Why Does Installation Matter So Much?
Even the best door can underperform if it is installed poorly. Homes shift and settle over time, and this is especially true in earthquake-prone California. Unless the door is going into new construction, the opening is rarely perfectly square.
A skilled installer accounts for this. The door should sit level, open and close freely, and be sealed tightly around the frame so drafts cannot find a path inside. Skipping that step is one of the most common reasons new doors fail to deliver the comfort homeowners expect. You can read more about our installation process on our website.
Why Do Homeowners Choose Professional Installation?
Replacing a door is a popular DIY project, but a less experienced installer may miss the small details that affect performance. With Progressive, you get trained installers and a one-call warranty on the doors we install. If there is a defect, you call us instead of chasing down the manufacturer.
We are also a licensed and insured contractor, with specialty licenses in window glazing (C-17) and insulation (C-2). Both reflect our focus on sealing and installation quality.
What Should You Ask Before You Buy?
A few questions can help you compare your options:
- How does the glass reduce heat gain?
- What type of seals and weatherstripping are included?
- Will the installer check that the opening is level and square?
- How will gaps around the frame be sealed?
- What does the warranty cover?
Consider the Whole Picture
If you are upgrading your entry door, it may be a good time to look at your windows and insulation too. Replacing several elements together can help your home perform as a complete system, and we can also help you find rebates through Energy Upgrade California and the HERO program.
