I am not sure If Ii am posting right or now... I normally don't do this, but I have been doing some research myself on melting siding and I came across your posts... We had just recently finished a second story addition to our home and had the whole house resided with Certain Teed vinyl Carolina Bead siding... It is the exact color and style as Joes. My garage side of my house has totally melted and looks exactly like your photos... I have all over the place with Certain Teed and have not gotten much accomplished... I did not belive that my neighbors one little up stairs window could have done so much damage, but then when I was out there today I saw that crazy X with the almost laser looking center... In deed the siding was hot to touch... this is sooo nuts... Joe what have you done???? If the window is replaced do you think it would solve the problem? I am going to call the manufactor of the window on Monday and see what they say as I find it hard to believe that this is going to have to be my problem... Either the window must have a problem or the siding must be of poor quality... Needless to say that is kind of what Certain Teed referred to us in not so many words... They offered to replace that side of the house, but now that I see that there really is a problem with the window I think that may be useless... any way instead of rambeling I am just wondering if you have figured anything out with your home. thanks...
