Sneakerphile..... best thing to do is measure what ur roof is made of and see what gap you have...as building regs have really changed alot over the years. Once you know how deep ur insulation can be check out some insulation websites like sheffieldinsulation.co.uk ( just google it if its wrong ), they have so many different types and also it comes premounted on boards depending on sizes etc.. they are a good place to get ur head round it all.
