San Diego 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).
The 80s San Diego County 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 like 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.
San Diego along with So CAL Homeowners figured out pretty fast that vinyl windows lower quality caused the frames to crack, peel, chip, and deteriorate in the summer and winter sun. Vinyl frames just didn’t hold up to San Diego County and California’s high temperatures.
In the late 90s, Infinity from Marvin started producing the first ULTREX® Pultruded window frames and San Diego County loved it. ULTREX® is the perfect material for San Diego 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 Frames so they still can have the problem with cracking, peeling, fading, and chipping.
