Is bubble wrap foil insulation any good?
Foil-faced bubble wrap is a radiant barrier. It’s not insulation. A radiant barrier reduces heat transfer by radiation and has two excellent applications in homes. Insulation reduces heat transfer by conduction through solid materials.
What is the best material to insulate a loft?
Firm boards of either synthetic or natural materials, this is the best solution for insulating the underside of your roof. The boards provide highly effective insulation for your loft space and can also be decorated over.
Does foil insulation keep cold out?

Does aluminum foil insulate cold?
It doesn’t only keep the food warmer for longer, but also keep things cold. It acts as a barrier to oxygen and air which can transfer heat to cold or frozen food. The bottom line is it helps by maintaining the temperature of the food, be it warm or cold.
Does foil backed insulation need an air gap?
Do you need a 25mm air gap under the membrane? Although this is often considered standard practice, it is not a requirement; the important thing is that the drape in the breather membrane (which allows any water getting through the tiles to channel down to the gutter) should not be pushed out.
Which way round does foil backed insulation go?
The foil insulation goes on top of the moisture barrier, followed by the roof covering. If you use bubble foil or rigid foam insulation, it also goes on top of the moisture barrier. Remember that there has to be an air space between the foil and the roofing.

Warm loft. An alternative way to insulate your loft is to fit the insulation between and over the rafters – these are the sloping timbers that make up the roof itself. You can use rigid insulation boards, carefully cut to size, or you can have foam insulation sprayed between the rafters.
Does foil insulation keep heat in?
Reflective insulation or an aluminum foil radiant barrier blocks 95 percent of the heat radiated down by the roof so it can’t reach the insulation.
How do I keep my attic warm?
How Can I Keep My Attic Warm In The Winter?
- Block windows. Just like you’d use heavy drapes to block the cold in your living room, it’s necessary to cover areas where leaks promote temperature shifts.
- Insulate the space.
- Extend your ductwork.
Why should we not use aluminium foil?
It causes cardiovascular problems: Excess use of aluminium foil for cooking or wrapping food leads to cardiac hypertrophy. It even leads to the decline of red blood cells in the body which impacts our entire body functioning. Thus, causing anaemia in the body. It ultimately also leads to the problem of liver failure.
Which side of foil should heat be on?
