You may choose to install a radiant barrier either between the roof sheathing and the attic floor insulation or in the cavity building envelopes such as walls, door opening or pipes. The cost of installing radiant barriers is lowest in new building or building under construction as compared to old buildings. The effectiveness of a radiant barrier depends on proper installation. When installing a radiant barrier you will need a staple gun, utility knife, tape, mask and a light. Before you commence consider unrolling the radiant barrier on the ground and cutting it into shorter lengths. The smaller pieces are easier to manage than the whole roll.

The radiant barrier installation process is guided by two very important factors. These are the area's climatic condition and the presence or absence of ductwork in the attic. In warm climates the radiant barrier can either be installed close to the heat source or laid across the insulation stretch. The latter is usually quick and easy as compared to the former. In cold climates the radiant barrier foil should be put on top of the insulation. The radiant barrier foil helps in reflecting ...
... the radiant heat back into the house as well as reducing the internal convection within the existing insulation of the house. Always ensure that all sources of moisture such as the bathroom exhaust fan from the inside of the house are covered.

Installing a Radiant Barrier on top of the attic floor insulation increases the rate of dust and moisture accumulation on the on the radiant barrier. To minimize dust accumulation on the reflective faces, a rolled-foil radiant barrier is allowed to drape between the roof rafters. A radiant barrier installed on the cold side of the insulation will acts as a vapor barrier thus reducing the chances of condensation occurring. When installing a foil type of radiant barrier ensure an air space is left between the material attachment and the bottom of the roof. The air space creates an air channel for the soffit and the ridge ventilation systems to function effectively. In addition the air space acts as a second reflector as a result of the two shiny sides.

If you are not in a position to install the radiant barriers properly, it is highly advisable that you seek the services of a professional for great and long-lasting results.
