Thermal curtains

Does anyone please know where I could purchase readymade thermally-lined curtains in different sizes, or get them by post in Ireland or from UK (tried the Intenet but it didn't help). The only place I have found them is in the curtain shop in Henry St in Dublin, but they are available only in sizes for french windows (ceiling to floor size) or for very large windows. I wish to use them on small north-facing (cold) windows. I have hung one on a north-facing french window and glass door and I find it very effective as an insulator.

we went to place out in carrickmines retail park. upstairs they had selection of curtain lining some of which was highly recommended from insulation perspective. i think they also have a make up service and price wise they were good.
cant remember the name but only a couple of outlets there

Thanks Jo9 -- Bricriu

I came across a guy who does thermal blinds while doing a house down in Dalkey. Guys name was Sean and the company was Setanta building Products.

I brought home a sample and they look good.

Argos sells a thermal roll down blind if that would suit you.
