low-emissivity or low-e glass is very common in multi-pane windows.
Often it is a silver oxide coating. By design it reflects infrared and
longer wavelengths.

I had a similar problem, though the distance was much less: ~25 ft (5 
feet between buildings, AP in my window sill, client 20 feet beyond a 
window opposite mine with LOS more or less to AP). The interesting bit 
was that when our windows were open, the signal was strong and fine.

After moving the AP outside and mounting a homebuilt 5dBi omni the 
client finally got a reliable signal. I've heard that dual-pane windows 
are coated with something that wi-fi doesn't like. Try having your 
neighbor open his/her window and see if the signal becomes reliable. If 
so, your neighbor will likely need a directional antenna of his/her 
own, or a warm sweater.

Hope this helps,
