Installation & FAQ

Why Should I Consider A Fiberglass Door?

Unlike wooden doors, fiberglass door installation can often be faster. It can also provide an immediate upgrade to your home’s aesthetics and energy efficiency. The lightweight and sturdy nature of fiberglass doors ensures they sit perfectly within the frame for a snug fit, minimizing air leaks and maximizing performance.

While fiberglass doors are easier to handle than their heavier counterparts, it’s recommended you get professional installation to ensure they are hung correctly, which is vital for their longevity and insulation capabilities. Allegheny Millwork & Lumber’s professionals have the expertise to address unexpected challenges.

What Types of Fiberglass Doors Are There?

There are numerous types of fiberglass doors — you can find wood grain textures that mimic the richness of mahogany or oak, or find smooth, contemporary finishes for a more modern look. Beyond the aesthetics, there are doors with glass inserts, panels, or doors tailored specifically for side entrances or patios. Fiberglass doors feature an array of finishes and hardware options that compliment your home’s unique style.

How To Insulate Fiberglass Doors

Insulation is one of the standout qualities of fiberglass doors. They are designed with a core of foam insulation, which excels at keeping warmth in during colder months, and keeping the heat at bay during the summer. This ensures a comfortable indoor environment and contributes to reduced energy bills.

Energy Efficiency for Fiberglass Doors

Fiberglass doors are excellent with energy efficiency. Thanks to their superior insulating properties, they act as barriers against external temperature fluctuations — perfect for those Pennsylvania spring and fall months that warm up during the day and get chilly in the evening! The result is your HVAC system will work less, and energy savings will be realized. Over time, this can offset the initial cost of the door. Think of your door as an investment!

What Fiberglass Door Materials Are Best for My Pittsburgh Home?

While all fiberglass doors have durability and insulation, the type can vary. There are two main types:

Sprayed-on: Typically has a smoother finish and is often more affordable.

Compression-molded: Replicates the texture of real wood more closely for an authentic look.

Security Features Of Fiberglass Doors

While the beauty and insulation of fiberglass door steal the spotlight, the security features are commendable. They are built to resist forced entry, with reinforced lock areas and solid cores. Many models also come with multi-point locking systems for enhanced security. You can pair them with shatterproof glass options to become a formidable barrier and have peace of mind.

For scratches and scuffs, a light sanding followed by a touch of matching paint can bring back the door’s original charm.
