Insulating a small roof space.

I m interested in this too op as our new old house has three attic spaces one in the original 1850s part has an easily accessible loft hatch whilst the 1920s extension has two tiny hatches of only 18 x 10 that only the teensiest of people could get through i know people used to be smaller but really. You need to insulate the attic even if you can t easily access it because it s a huge risk for air leaks and potential heat loss. It creates a breeding ground for mold and mildew and ruins the air trapping pockets that block heat flow. These gaps create pathways for warm interior air to leak into the attic wasting energy and causing attic condensation or even ice dams in cold climates.

If you ve ever wondered why your attic has insulation it s because it acts as a barrier against temperature extremes. Even small holes can let a lot of air escape. Most codes require a specified minimum amount of headroom and it s tough to meet this requirement when insulating a finished attic especially since most. Currently the two smaller attics have zero insulation so anything would be an.

Box out light fixtures. You need to make sure that ductwork is properly sealed to prevent moisture build up in the attic. And having insulation in your attic keeps the area at a consistent temperature. To meet all three goals insulating your finished attic ventilating the roof and maximizing headroom use a combination of dense batt insulation rigid foam sheeting and air chutes.

Having insulation in your attic can help you save up to 20 in heating and cooling costs. Before fitting any insulation to the sides of a pitched roof space any repairs to the roof should be completed once the insulation is in place it will be harder to spot any leaks inside the roof and any leaks will soak the insulation itself. Water is insulation s enemy. Insulate and air seal any knee walls vertical walls with attic space directly behind them in your home as well.

Look for water stains on the roof sheathing or damp or moldy spots on attic joists and existing insulation as a clue to where leaks might be. Insulating a roof is perhaps the easiest of all the energy saving home improvements. Before insulating seal any air leaks and make roof and other necessary repairs.
