Patio Doors Frequently Asked Questions

What should I look for when buying a sliding glass door?

When searching for a new sliding glass door, it’s important to consider your desired level of security. Consider buying curtains, installing an alarm system, and ensuring the sliding door will lock securely.

You should also ensure your new sliding glass patio door will be durable, as it will come up against the outside elements throughout all four seasons.

Look for sliding glass door options with thick glass, and consider using vinyl on your door frame to keep it from chipping. Lastly, if you’re looking for ways to save money on your energy bill, choose an energy-efficient sliding glass door. Make sure your new door will have tight seals to avoid costly air leaks.

What’s the most energy-efficient patio door?

It’s important to consider your patio door’s energy efficiency, as it could save you money on your utility bill in the long term.

Zen Windows provides patio doors that operate at optimal efficiency, using argon-infused glass, high-density foam insulation, and triple-fin weatherstripping to help reduce energy costs and keep your home comfortable.

How can I make my patio door more energy-efficient?

The most important first step in ensuring maximum energy efficiency for your patio door is having it properly installed. You may not need a professional, but it’s not worth risking DIY installation if you don’t have the necessary expertise.

Zen Windows offers expert installation services at an affordable price while ensuring you get the energy-efficient doors you want.

Weatherstripping is another important consideration. Older doors were often installed without weatherstripping, but most modern patio doors can accommodate energy-saving weatherstripping installation.

Double-paned glass is more efficient than single-paned, so have your patio doors equipped with double-paned glass to maximize efficiency.

What areas of Pennsylvania do you serve?

Zen Windows Pennsylvania proudly serves Lancaster and Pittsburgh, PA, and the surrounding areas, including Harrisburg, York, New Cumberland, Chambersburg, Hanover, Bethel Park, Cranbury Township, Mount Lebanon, Penn Hills, and Wexford.
