Problems With Marvin Patio Door

Marvin installed a sliding glass door in our home this fall. This week we had our first subzero temps with gusting wind. We noticed a lot of cold air around the door that slides. It leaks all around the floor and on the side  for several inches. I did the match test (hold a lit match up) and it blew it out! Is this normal? I thought a Marvin brand would be better than that.
The installer is coming back out to look at it, and I just wanted an idea of what to expect.


If you’re getting a draft that puts out a match…well, that’s a whopper of a draft. A well-installed patio door should not have that problem. Luckily, I think your problem can be solved with a simple bead of caulk and better insulation.

When the installer comes back out, have him to do two things. First, he should caulk all around the outside of the door. Second – and this is very important – have him remove the inside trim around the door and fill that space with a
minimum-expanding foam insulation. All of my installers use it. This insulation dries quickly and is very effective. Then they can replace the trim and you should be in good shape.

Here’s a great insulating foam sealant from Dow Chemical to try:

Let me know if this works for you.

    Hello there. I simply just wanted to show you that certain parts of your web site are hard to read for me, for the reason that I’m color blind. I’m troubled by deuteranopia, however you will find a lot more types of colour blindness which will also get problems. I can recognize the biggest section of the site Alright, and the locations I have difficulty with I’m able to read using a specific web browser. However, it would be cool if you would keep in mind us color-blind men and women when doing your next website revamp. Thanks a lot.
