  1. Insulation
    I live in middle Tennesse, hot and humid summers, somewhat cold and wet winters. I have a Tuff shed (16'x12') I want to convert to a conditioned space. I already have the walls insulated, but the roof poses some uncertainties. It doesn't have a ridge or soffit vents, although I could drill some...
  2. Insulation
    I have a 2 story house built in 1974 which in the summer one of the exterior walls that gets full sun in afternoon will get extremely hot inside and out. In The evening the outside of the wall (stucco) will get so hot, you can only hold your hand on it for about 10 seconds. The outside wall will...

    I moved a kneewall in a home office and had a crew finish the ceiling for me. So I have a knee wall facing an unheated area I will use for storage. This storage area is where the roof angles down to the soffit vents and creates a triangular shaped space. When the office was smaller, I sealed the...

    I already purchased some radiant barrier products and it's really help in reducing the heat gain into my house and now I am planning to install more. So I surf the internet to find more information about it and found some technical data sheet. I don't really understand why radiant barrier must...

    I live in Tampa, Florida, on a lake with little shade. It's very hot and miserably humid! I recently had my roof replaced and the roofer sealed the existing ridge vent and installed 3 box vents. The roofer didn't tell me that he planned to change the venting system. In defending the change...

    First, thanks to everyone giving advice on here. Getting the knowledge before starting a project is so empowering to a new homeowner like me. My South Louisiana home- built circa 1968- was unbearably hot during the summer months. It is about 1850 sq. ft., all one level, and completely...

    I just read that for a radiant barrier to be effective, 80% of the surface area must be covered. My house is in climate zone 5A. I have an original finished attic room that I am just beginning to insulate properly. The house was built in 1950. For the past six decades this house has leaked...

    I'm in Santa Monica California and have a walled outdoor patio area adjacent to my house that I'm going to put a patio cover over. It will have open sides with curtains to retain warmth from a ventless fireplace. It gets chilly here at night even in the summer so I'd like to help the situation...

    I have a 12 year old two story house in Atlanta that sits on an unshaded hill facing West. I get full sun most of the day and the second story is very hot. I'm trying to decide between installing a radiant barrier (e.g., Radiant Guard) vs. eShield. My attic is already well insulated, so...
  12. Building & Construction
    We're finishing our attic space and want to insulate it really well. I want to use a radiant barrier like Reflectix but am concerned about using it with faced insulation. If I have kraft-faced insulation and then put the radiant barrier on top of it will there be an issue with moisture? Also...
