Thermal Window Coverings

[Bug_out_Bag]

Last year I made some thermal curtains for a small window in a spare room created from a couple of brightly coloured, baby's fleece blankets with two layers of emergency, (Mylar), space blanket as lining. They were knocked up in a hurry but they proved to be highly effective if not that elegant. I'm now just about to start making thermal linings for some black out roller blinds in several rooms and have been looking around the web for some ideas and found this interesting company tha t makes thermal Roman blinds which consist of:

"...five layers ...

1. Room side fabric – 100% polyester with blackout surface
2. 12mic Aluminised Mylar (space blanket)
3. 7mm Thinsulate (‘Clo’ value of circa 1.1)
4. 12mic Aluminised Mylar
5. 110g cotton sateen lining fabric

The inner layers incorporate a 7mm Thinsulate core (a highly insulating thermal fleece, normally used for clothing), with two layers of aluminium faced Mylar (‘space blanket’ material as developed by NASA) either side of the core."

Thinsulate is about a fiver a meter and so I'm going to order some and copy their idea. I could of course buy them ready made at around £150 per square meter from these peeps:

but I think I prefer to make them and buy a few more rounds, tins and things!

Has anyone else had a go at making something like these?
