The final method of installing a radiant barrier in an attic is to lay it over the top of the insulation on the attic floor. While this method can be more effective in the winter [ 12 ] there are a few potential concerns with this application, which the US Department of Energy [ 11 ] and the Reflective Insulation Manufacturers Association ...
Insulation is a barrier material to resist/reduce substance (water, vapor, etc. ) /energy (sound, heat, electric, etc.) to transfer from one side to another. Heat/ Thermal Insulation is a barrier material to resist / block / reflect the heat energy (either one or more of the Conduction, Convection or Radiation) to transfer from one side to another.
Now, insulation is divided into two main categories: bulk insulation and reflective insulation. Buildings typically use a combination. Insulation is an important economic and environmental investment for buildings. By installing insulation, buildings use less energy for heating and cooling and occupants experience less thermal variability.
Warm air rises, so ceiling insulation is designed to have a higher r-value and the insulation is often installed between the ceiling joists or rafters. A properly insulated and ventilated roof is called a cold roof. A warm roof is a roof that is not ventilated, [9] where the insulation is placed in line with the roof pitch. [10]
Providing ventilation under the roofing material that carries escaping building heat elsewhere and assures a cold roof surface. Attic/roof temperatures can be controlled by installing sufficient insulation and providing natural or mechanical ventilation to produce a "cold roof" to keep the roof temperature below 30 °F (−1 °C).

A loft conversion or an attic conversion is the process of transforming an empty attic space or loft into a functional room, typically used as a bedroom, office space, a gym, or storage space. Loft conversions are one of the most popular forms of home improvement in the United Kingdom as a result of their numerous perceived benefits.
