good start on insulation,
This review is from: Loft Conversion Manual (Hardcover)
I looked at several books on loft conversions and this one is one of the best books. It is the only one that really starts to deal with insulation. But it is unfortunately not complete and I would have liked more `good practice' on the subject. If you ask your builder to do exactly the same as in the pictures on page 197-201 and make sure he does it, you're OK - ish (read also the other pages!). A good place to look for good practice is on the planning portal of the government and look for the `accredited construction details'. There is a Scottish version too.
Don't trust your builder, even if he is (or pretends to be) a `specialist'. Ask lots of questions and keep asking and make sure you keep a close eye on the construction. In the vast majority of cases you need 2 layers of insulation: a lot of builders and architects get it wrong. I would certainly recommend this book over the other ones.
