Aluminum

The most common window frame and material used on Houston homes for decades has been Aluminum and Aluminum Frame Windows. While new materials such as vinyl and fiberglass have some efficiency benefits, aluminum windows and aluminum frame windows continue to be the desired option for new custom homes as well as for replacement windows and doors.

Vinyl

Starting with the vinyl formulations, every manufacturer uses a different 'recipe' that includes components that affect the longevity, heat resistance and strength of the vinyl.

Fiberglass

The gulf coast climate is one of the toughest around! Intense heat during the summers, humidity, ultraviolet rays, salt air near the coast and the potential for hurricane force winds - our climate tests the best windows! These are the challenges faced by Milgard's engineers to create the most durable frame material possible for windows and doors.

Sliding Patio Doors

Sliding Patio Doors can have slim frame profiles to allow the maximum natural light into your home, or they can have wider French frame rails to create the look of a French door while maintaining the compact space requirements of a sliding door.

French

French Doors has an elegance and style all their own and can dramatically change the look of your home. Whether you are replacing an existing door or changing a sliding door to a French Door system, let Custom Window craft a solution to meet your budget in Vinyl, Fiberglass or a Fiberglass Clad Wood French Door system from Milgard.

It's about 35° outside now. I used to have to have to wear a heavy fleece pullover to keep warm while sitting and working at the dining room table. Now, I'm comfortable in a long sleeve shirt. What a difference these windows make! We just received our electric bill for May. Compared to the same period last year, our average daily usage (kWh) is... Full review ›

We are really really enjoying our windows. They are wonderful and really make a difference with these powerful winds we have had in the last week. And then we had sideways rain and thunderstorms the other night and I slept thru it. I didn't even know it had rained until I went outside. They are fantastic! Thank you again. Full review ›

Unfortunately, I had a horizontal sliding window fabricated backwards from specification. I realized this after installing it. The window opened crooked since the tracks were on the wrong side (upside down). Full review ›

The Custom Windows team did a first class job from measuring, explaining the options, giving us samples to decide with, and most importantly, references from other satisfied customers.
