Best for keeping in heat? lined curtains or blinds

[swiftkick]

We are moving into our new house- DS's room is North facing and our house is 100 years old so I want to make his room as cosy as possible. I think lined curtains are the best option but OH thinks blinds are best for keeping heat in...? Oh wise women of Mumsnet who is right?

I've got both! Lined and interlined curtains and a lined and interlined blind. Makes a huge difference!

I would also say both. And make sure you have curtain rails, not silly farty poles (this house is plagued with them) - poles stand away from the window and so all the heat escapes. That is what pelmets would prevent but the mere mention of those is a mumsnet crime.

We have thermal blackout blinds in the recesses of the windows in all the bedrooms/bathroom and then lined thermal curtains in the bedrooms and lined roman blinds in the bathroom. Does make a difference.

Both. But if you were to opt for just one I would go for the curtains. Long term if you are up for it we put under floor insulation in our very cold house and it helps a lot. It also stopped the spiders getting g in!
