It is easily cut and placed and reflects heat rather than absorbing it.
Fitting roof insulation foil.
Ensure overlaps are fully taped and sealed using thermaseal foil joining tape.
When installing foil insulation you must use a quality stapler.
Also when you overlap the joints be sure to keep it to a 50 mm lap.
Foil insulation works slightly differently however.
Whilst there will be some resistance to conduction thanks to the air gaps between the layers of foil most of the performance of the material lies in its ability to reflect radiative heat back into the room.
Conservaheat ultra high performing conservatory insulation system is manufactured from true aluminium foil which provides a radiant barrier that reflects 98 of radiant energy to maximise heat reflection and heat retention.
Usually reflective foil is about 25mm thick and gives a very good u value for its relative thickness.
Remember to apply a decent amount of tension when stapling and to do it at 50 to 100 mm intervals.
Reflective foil insulation installation on a roof is usually done in the ceiling attics or other spaces that separate the roof from the ceiling.
Reflective foil insulation is made from layers of aluminium foil surrounding a wadding or layer of wool material.
After you are done cut to adjust the length and get ready to work the next layer.
Due to the varying nature of the construction of buildings each property may require a slightly different approach when installing insulation on the roof.
