Multi-slide patio doors

Multi-slide patio doors feature multiple sliding panels available in uni-directional or bi-parting configurations and customizable widths. Also called scenic or panoramic doors, multi-slide patio doors maximize fresh air, sunlight and views.

Swinging patio doors

Swinging patio doors are available as French doors (a pair) or as a single hinged panel. We can install a single or double swinging patio door to swing in or outward.

French patio doors

French patio doors include two swinging doors with glass panels allowing plenty of natural light. We can install French doors to swing inwards or outwards. French patio doors add elegance and open wide for convenient movement to and from your outdoor space. 

Bifold patio doors

Folding patio doors (bi-fold doors) are slim and practical, folding away to the side like an accordion and creating an opening as wide as you desire. These doors provide safe and convenient access for deliveries, wheelchairs and other mobility aids.

Are patio doors energy efficient?

Modern patio doors are much more energy-efficient than older models. Advancements in door materials and insulating glass have greatly increased the efficiency of all styles of patio doors. Choosing an experienced patio door installer ensures your new patio door is air and water-tight for the good of your energy bill and your home’s integrity.

Do I need a building permit to install or replace a patio door?

In general, if you are replacing a door or window without changing the structure of your home, you probably won’t need a permit. If you’re changing a window to a doorway or creating a new door opening, you probably will. Homeowners should check with their local jurisdiction before starting DIY home improvement projects. Infinity Exteriors has decades of experience installing and replacing patio doors across southeast Wisconsin. We’re happy to address any questions or concerns you have about permits for your Infinity Exteriors patio door installation.

Are patio doors standard sizes?

Yes and no. There are standard patio doors, usually with a height of 80 inches (6 feet, 8 inches). Infinity Exteriors works with industry-leading patio door manufacturers who offer a variety of standard sizes as well as custom-built swinging and sliding patio doors. No matter the dimensions or shape of the patio door you have in mind, Infinity Exteriors will help you find the ideal door for your home.

Can sliding patio doors be reversed?

Sliding patio doors typically have one panel locked in place while the other slides. It's sometimes possible to reverse the fixed and sliding panels depending on the brand of door and type of frame. Contact our patio door installers to find out if your existing patio door is reversible. When Infinity Exteriors installs a new patio door you can choose which direction you want it to slide or swing open.
