How is the best way to start a window replacement project in Los Angles County

We always ask homeowners in Orange County CA why do you think you need new replacement windows? After thinking about it for a minute, we usually get answers like the seals are broken, they are drafty, they are warping and leaking, and they’re cheap old windows that have lost all energy efficiency. The answer to this question is usually they are old, worn out, and need to be replaced.

There are three main reasons homeowners want new replacement windows in Orange County. Better energy-efficient windows, they want windows that will keep their home quiet from all the outside noise, and especially in San Diego County, they want the beautiful look of elegant replacement windows.

Los Angeles County homes are famous for big picture windows, patio doors, and french doors. Los Angeles County homeowners love more light and the open flow that large windows and doors provide. Dual-pane glass can be very heavy depending on the size of your window. The larger the window the heavier the glass. The glass and the frame that supports it must expand and contract equally, if they don’t they pull away from each other.

If the glass expands at a 4.6 and a vinyl frame expands at a 30.0 when the frames and glass heat up the frames heat up and expand 652% more than the glass, the frames pull away from the glass and your seals fail.

Ultrex Fiberglass Frames are as Strong As Steel!

When the sun beats down on a window, the window and the frame expand with the heat and contract with the cold. Our Ultrex fiberglass frames expand and contract at a 4.0 while the glass expands and contracts at a 4.6. The two materials expand and contract together equally. When the 4.6 glass heats up it expands against the Ultrex 4.0 unmovable frame and the glass stops there, it cannot expand against the Ultrex frame so your seals do not fail.

Los Angeles County went through the same phase of construction windows as the rest of California. In the 50s wood was the material used for window frames. Wood windows are beautiful and everyone loves the classic look of wooden windows but the weather is hard on wood windows the repainting, maintenance, and upkeep are costly and time-consuming. Homeowners wanted a more maintenance-free window.

The 60s and 70s brought Aluminum frames, aluminum was used because it was stronger than wood plus you never had to repaint and the maintenance was a lot less time-consuming, but no one really liked the look of an aluminum window they were used more for track housing it was an easy product for builders to use but not the most energy-efficient, (remember aluminum transfers heat and cold).

In the 80s Los Angeles County sold more vinyl windows than the rest of the country. Vinyl was the new material for window frames it was not as strong or kept its true shape as aluminum but it was cheap and easy to mold. However vinyl frames always look bulky, they must be manufactured wider and thicker in order to support the heavy dual-pane glass. Remember vinyl flex’s and moves a lot. The glass inside the frame expands and contracts at a 4.6. while the vinyl frames expand and contract at a 30.0. As you can see the vinyl expands 652% more than the glass, the frames pull away from glass, and the seals break and fail.

Ultrex Pultruded Fiberglass

Los Angeles County Homeowners figured out pretty fast that vinyl windows were cheap, they frames crack, peel, chip, and under the Los Angles summer sun they deteriorate badly. Vinyl frames just didn’t hold up to Los Angles and California’s high temperatures. In the late 90s, Infinity from Marvin started producing the first Ultrex Pultruded Fiberglass window frames and Los Angeles County loved it. Ultrex Fiberglass is the perfect material for Los Angeles County, it stays to its true fit through the horrible 120 degree days and the cool 25 degree nights. It will not chip, crack, peel and the color will never fade, (Even in Black) Infinity from Marvin ads that extra Acrylic finish to both the inside and outside window frames to keep your finish looking beautiful for decades to come

Combination Frames made from more than one material

In the first part of 2000, some other window manufacturers developed other types of combination material frames made from vinyl and other different materials. The purpose of this was to add other stronger materials to the vinyl during the manufacturing process in order to try to make the vinyl frame stronger. First, they were trying to keep the vinyl frame from expanding and contracting more than the glass that it surrounded. But also to they were attempting to keep the vinyl from cracking, peeling, chipping, and fading.

Some of the manufactures had minimal success with this type of combination window frame. Renewal by Andersen Fibrex material is one company that had some success with this. However, they have the same challenge that other manufactures had. The glass inside the frame expands and contracts at a 4.6. the Fibrex material frames and other combination frames expand and contract at a 16.0. As you can see the combo material frames expands 347% more than the glass, the frames still pull away from glass, and the seals break and fail. Also, combination frames do not have the same protection as Ultrex Pultruded Fiberglass Frames so they still can have the problem
