My GC really likes Thermatru if you are going fiberglass. I looked at them but I haven't firmed up French door orders yet. I doubt you will get double the quality but the Andersen door may be better to some extent. Have you seen and felt both in person?

I had the same issue, and did the thermatru. They look fine.

TT is a good door but the Andersen for a French Door is much better (yes dbl in my opinion) especially for a deck or patio without much of a cover.

We're going to do the exact same thing. We had three sets of Anderson french doors in the rear of the house. We decided to change two of them to Therma Tru to trim our budget.

Did them come in yet Dreamer? What do you think?

I've seen both (I own a Therma Tru entry door, but not the Andersen), but its hard to say without comparing them side by side.

The Andersen Frenchwood is actually 3 times as expensive as the thermatru for a 5ft French door.

No we haven't started construction yet but they are in the contract. We just couldn't afford to have all three sets be Andersen. So we opted for a set of Andersen exiting the great room because it will also have many other Andersen 400 windows around them. The other two french door sets are separated from the first and from each other. So we're certainly hoping that will help to make them more indistinguishable.

Are they a true french door system or entrance doors hung as a double door ? What type of sill (a patio door will have a much higher sill not an entrance door sill this making it a tighter seal)?

Make sure you check the price difference after adding the multi point system--it's a HUGE upcharge. We planned for TT with multi point lock, but it cost less to get a Neuma with the multi point than the TT with multi point.

Excellent point. Didn't realize that the French wood 400 by Andersen already included the multipoint AND hardware, and the Thermatru did not. Now the price difference is "only" $1000. I may go with Anderesen.

Frenchwood is all wood.... should I be concerned about the elements (snow) as this door will not be protected. It doesn't say "fiberglass clad", but mentions coatings and "will never flake, peel, etc".

It is a (if memory serves me) a factory applied finish (a heavy type paint) that should not really ever need to be re painted. I forget did you ever look into Integrity by Marvin?
