Am I using foil the wrong way round?

I once saw a person sunbathing with silver foil reflecting ( pompa ?) the sun to get under her chin brown. Ooo er mrs !!!

under the chin wrinkles... oh yes!

<eyeroll>

pompa you are such a mine of information. Thank you for reminding me of the basic science. Every time I come on to GN I learn something ?

Nana3. Yes silver foil would reflect radiation (the Sun) very well.. This is why we can get sunburn from snow.

Jud... Sorry if I'm teaching my granny to suck eggs.

No seriously pompa I was grateful for the info. Needed to be reminded about egg sucking.

I have just seen an advert for the stuff and on the top right hand side it says use dull side inside.

I always do shiny side in because it will reflect the heat otherwise, or so I was told years ago?

Whichever way works for you I suppose

Perhaps if the oven has an element glowing red or white hot like a grill it might reflect it, but most heat in an oven is convected through heating the air in it, not radiant, so I am not sure that reflecting it is all that relevant.

In a grillpan, under the meat being grilled, reflecting the heat back up from the shinier surface onto the underside of would make sense - but does it really do that?

Irrespective of the foil dilemma, I'm loving that The Galloping Gourmet, Graham Kerr, just got a mention. I loved him. Re the foil, I kind of understand the logic of shiny side in, but I'm going to be reckless and carry on using shiny side out. Hard to change the habits of a lifetime.

Okay, now that the foil is sorted, please can anyone (*Pompa*?) tell me which way blackout curtain lining should go? Suede-y side to the curtain or smooth side to the curtain?

just looked at my curtains , they have the hem turned up onto the suede side so that is the side turned to the curtain ............ otherwise it would look untidy from the outside and we don't want neighbours sniffing , do we ?

Mine are suedey side outwards as well, partly because of the way they're hemmed but also because the 'other' side is a pale greyish colour which doesn't go with anything. The suedey side is beige.

Sorry. not a Scooby Doo, we don't have any black put curtains.

The only blackout ones we have are from JL and in the small bedroom (not expensive ones, they are for a child's bedroom).
The suede side is outwards facing the window, hem to hem on the inside.

Great, I think I understand. Mind you, My brain goes all fluffy every time I try to make curtains so will need to keep coming back to re-read this!

If you count the nicer suede side as the 'right side' then that faces the window on these JL curtains. The 'right side' of the curtain fabric is obviously facing the room. The hems face each other in between curtain and lining - two 'wrong sides' together, hems facing with the lining a bit shorter than the curtain.
If that makes sense!
