 Re: Core of the window

Author: Fenestration Expert (---.dyn.optonline.net)

Since when you ask? Foam coring has been used to support weaker structures since the 1950's because it's inexpensive to use and easy to apply to all shapes. The "Tin Men" used the foam backing on paper thin aluminum siding to keep it from denting as easily claiming it was for insulation purposes but if you have ever seen a piece of it... it was void at every course for installation ease (defeating it's claimed purpose). Other uses have been shower basins, soles of shoes and as a packing material to ship fragile items due to it's rigitity. Common sense states that steel and aluminum do conduct but can't when concealed in non-conductive casings (i.e. the wiring in your house wrapped in vinyl) and is much stronger than wood or vinyl. As stated before... if your concern is energy usage reduction, remember a window is 80% glass, and glass is responsible for 60-80% of your heating and cooling bills... not the frames.
