Original single-pane windows being shown here in this S.W. West Hills area home are Aluminum. We probably had 4 or 5 early morning pre-contract meetings here with our client discussing product specifications and options before the exact replacement product was chosen.

Most folks are replacing old original aluminum windows with Vinyl. Our client, who was a retired structural engineer and who originally had this house built could not warm up to the notion of losing so much daylight with the thicker frames & sash common to Vinyl windows.

Wood windows presented the same limitation, along with the added liability of sitting up on a hill with zero protection from the elements. Wood-windows and the lack of eves or awnings is not a good combination. Such are the potential downsides of these contemporary designed structures.

So between our client and his original architect, the decision was made to stay with Aluminum-Frames. Albeit thermally-broken aluminum frames. One of the largest hurdles was finding a window manufacturer who could build these three 15 foot tall front facing windows.

As you can see from the 1st photo, the original windows had a horizontal mull-post 2 feet up from the bottom. Due in large part to the current size-limitations of glass manufactures, it was deemed that a second horizontal mull-post would be required. No one wanted to manufacture a 13 foot tall insulated glass unit.

If you are able to look closely at photo #4, you may be able to make out that additional mull-post near the top of the new windows we are being shown installing there. This mull-post was placed to coincide with the wood-railing that went around the loft balcony above the living room, so the mull posts existence, as viewed from the interior, was aesthetically minimalized. As you can see by the photo above, we had MARLIN Windows build these three 15 foot tall windows. See www.marlinwindows.com

All the rest of the windows in the house were specified to be Milgard Aluminum Windows. Both brands sported Low-E Insulated glass and Thermally Broken Frames. To read more on Thermally Broken Frames, go to; http://wiki.Answers.com/Q/Wikipedia_what_

Logistics on the front of the house were challenging installing those 15 foot tall window assemblies, but the back of the house also posed a considerable need for implementing careful and safe practices to reach the dining room window openings. Here we are shown employing the use of our pump-jacks.
