The materials used to insulate under the roof include batts of mineral or glass wool insulation held in place by battens of wood attached to and across the rafters alternatively polystyrene.
Fitting roof insulation foil.
The process is more tricky than installing foil insulation during the construction of a property but can be undertaken if need be.
We would recommend going for one with plenty of layers and some heft to it as the thinner ones will not.
It is easily cut and placed and reflects heat rather than absorbing it.
Usually reflective foil is about 25mm thick and gives a very good u value for its relative thickness.
Reflective foil insulation installation on a roof is usually done in the ceiling attics or other spaces that separate the roof from the ceiling.
Superquilt can be easily cut using multifoil scissors or a cutting knife both available in our multifoil fitting kit.
How to install foil insulation on roof.
Reflective foil insulation is made from layers of aluminium foil surrounding a wadding or layer of wool material.
It is always recommended to fit a film to clear glass conservatory roofs.
Most people consider the foil looks appealing from the outside.
Foil insulation is worth considering if you have restricted space in your loft or roof space that means regular insulation is not viable.
Ensure all superquilt insulation joints are overlapped by min 50mm.
Ensure overlaps are fully taped and sealed using thermaseal foil joining tape.
If you choose the former we recommend you start out from the bottom and work your way up by ensuring the insulation overlaps at each junction it meets.
Importantly it allows full reflection of radiant energy without any barrier.
Foil insulation is a radiant barrier and it works by.
You will have to ensure there are good air gaps either side of the foil to get the best performance.
Foil insulation underlayment is recommended under a metal roof and in most cases the shiny side should be facing up but there s a catch.
