Loft insulation

[solarsecurity]

Hi,

Ihave a loft which is loosely insulated to a depth of approx 10cm. Is this deep enough or should I fit some more?

B&Q have some really cheap stuff so thought I may add some more to help in the winter

Another 2 layers is the standard upgrade. Lay them at right angles to each other.

Lay them at right angles to each other.

I'll remember that when I do it. Thanks!

That's just an arbitrary Gov figure.

Insulation benefits decrease significantly once you put down 200 mm. If it's really cheap however and you have the space, put down all you want whilst leaving ventilation into the loft open.

If you're a British gas customer, give them a ring.

They will install some for free.

I think you have to meet a criterea, but they will explain all that to you.
