A few tips before you start
Almost all insulation is lightweight and easy to handle. Few tools are needed, but care should be taken when you're working with mineral fibre-type insulation. Small insulation particles can cause skin irritation and itching. It's a good idea to wear gloves. And a shower at the end of the day will wash away particles left on the skin.
When you're ready to start in the attic area, pull on a pair of running shoes and watch your step. Walk only on the ceiling joists. Most ceiling surfaces under the joists are plastered; too much weight will puncture the ceiling. Boards laid across the joists will give you a sturdy working platform.
To cut batt or rigid insulation use a sharp penknife or blade. Lay the insulation on a flat surface and cut to make the flanges as shown in the diagram below. Any accidental cuts in the vapour barrier should be taped before the insulation is finally applied.
A heavy-duty staple gun is essential for applying batt insulation. You should be able to rent one from your insulation supplier or hardware store.
Measure your walls and floor and attic area carefully. Once you've decided on the R value you need, talk over your requirements with the dealer. He'll help you figure out the right number of bags or bundles of insulation. It's bulky, so have it delivered. Store it in a dry place until you're ready to start to work.
