What Are New Construction Doors?

New construction doors are specifically designed and built for new homes or buildings. Unlike replacement doors, which are made to fit into pre-existing frames and openings, new construction doors are installed as part of the initial building process. Installing doors for new construction happens when the walls are still open, so that the door frame and any necessary structural support can be integrated directly into the home’s framework. At MILGARD, we focus on new construction patio doors that transform your indoor-outdoor space into an oasis.







New construction doors are part of the original building process, so there's more opportunity for customization. Homeowners and builders can specify dimensions, materials, styles, and finishes that perfectly match the architectural style and functional needs of their home. For example, they can choose frosted glass for privacy or low-emissivity (low-E) glass for improved energy efficiency. The ability to tailor every aspect ensures that the door not only fits the exact opening but also complements the home's design.

Energy Efficiency

New construction doors are designed to be highly energy efficient. They typically come with better sealing technology, insulated frames, and advanced glass options, like double or triple glazing, that minimize heat transfer. These modern weatherproofing features enhance sealing and insulation, reducing energy consumption and lowering utility bills.

Durability and Security

The materials available for new construction doors have also improved over the years. They’re built with robust materials that can withstand harsh weather conditions, preventing common issues like warping, shrinking, or rotting over time. They also have advanced locking mechanisms and reinforced frames that enhance security. With professional installation, they provide a stronger, more secure fit than older doors.

New Construction Patio Doors: Things to Consider

Both new construction windows and doors must be planned out during the building process so they can be installed as the home is built. Here’s what you’ll need to consider as you plan.


Space and Placement

Generally, patio doors are available in in-swing, out-swing, or sliding operation. Consider the size of your space, both indoors and outdoors, and the layout of your home. Swing doors are ideal for spacious areas while sliding or pocket doors can maximize limited space. Bifold, pocket, and stacking doors are also popular options for areas where you entertain because they have a large opening that allows for a flow of people. 

Sunlight and Energy Efficiency

It’s important to consider how light enters your home. If your doors get a lot of light during the hottest parts of the day, consider tinted glass, Low-E coatings, or obscure glass to filter the UV rays. If you want to boost the sunlight, opt for a wide opening and clear glass. No matter what you choose, always go with new construction doors with proper seals and energy-rated glass to keep your home comfortable while using less energy. 

Architectural Style

Both doors and windows in building construction can be seamlessly integrated with your home’s design. Traditional homes benefit from vinyl doors in classic colors, while modern styles might be minimalist, with clean lines and sleek materials. Consider the visual impact of your doors and how they'll tie into both the exterior and interior of your home.

Vinyl Construction Doors

Vinyl new construction doors are known for their cost-effectiveness, low maintenance, and excellent insulation properties. They’re made from durable PVC (polyvinyl chloride), which provides outstanding resistance to moisture and decay, making them ideal for climates prone to heavy rain and humidity. Vinyl is also an excellent insulator and requires minimal maintenance because it doesn’t need to be painted or stained.

Fiberglass windows

Fiberglass Construction Doors

Fiberglass new construction doors offer versatility and durability and are a great choice for nearly any climate. They’re constructed to withstand severe weather conditions without warping, denting, or rusting. Fiberglass is also excellent for thermal insulation, improving a home’s energy efficiency. Like vinyl, fiberglass doors are low-maintenance because they don’t rot, corrode, or require repainting.


Aluminum Construction Doors

Aluminum new construction doors are strong, sleek, and cost-effective, making them a popular option for homeowners. They’re lightweight yet strong, offering a sleek, contemporary look with slim frames and large glass panes that maximize natural light and views.
