The idea material to block radiation is a metal surface like foil. Our block out honeycomb blinds have a metal lining. My explanation of an insulating layer of air was simplified. It is one thing for the air to be trapped against the pane but heat is still conducted directly through the material. The layer of air next to the curtain facing into the room is also cooled and the same thing happens. Insulation requires multiple layers or pockets of air to maximise the effect. Hence the suggestion for thick heavy curtains (or in our case, honeycomb blinds). The best way to imagine it is when you go out in the cold. Multiple thin layers of clothing is better than one thick wooly jumper pulled over a T-shirt.

Re: Glass windows & doors - question re heat loss 23Feb 14, 2012 1:59 pm Hi Ceebs, I agree with Ed. His suggestions are reasonable and practical. I guess what i can add on to some of our friends suggestions, if your problem is heat from sun then use awnings especially on your east and west facing window atleast to block the rays of the sun. With this you can open your windows without having the rays of the sun coming inside your home plus you can get fresh air from the outside. Blinds are better to use in warm weather than curtains and i think if you use too thick draperies it would cause more heat inside the house. I think air circulation is the basic idea in having a cool indoors. Anderzzz here! What do you need them to withstand? If it's normal wear and tear, then either will do, if you want resistance to ingress then laminated would be the favourite, but only… 1 12379 I don't know them all, the first 2 top of your list are best known.
