Hello, does anyone know what is good to use on sash windows? Its frezzing near my windows and the weathers not even that cold yet! i have looked on internet and i dont have money to call in someone to pull out window just looking for a cheap/ reasonable alternative. My DIY knowledge not very good, if someone can give me a name / seal/ strip to get from DIY store would be great preferable not foam strip as i used these last year and all look manky now and fallen apart. MAny Many thanks
