Loft insulation

Nonnadiluca

We have a 1960's detached bungalow and need to improve the insulation in the loft.
Q1, what's the best type to go for, I would like to be as eco friendly as possible but cost is a factor?
Q2, we have downlighters in the kitchen and bathroom; is it safe to cover electrical gubbins with insulation?
Q3, is it worth having insulated boards fitted?
Advice appreciated, thanks.

A1 - Fibreglass is both cheap and readily available. Some will say use sheeps wool, but it is likely to be a food source for small moths.

A2 - Intumescent covers will stop the spread of fire through the holes. Fit LED lamps and you'll reduce the amount of heat generated.

A3 - Just insulate the loft, and you'll not need any additional boards.

A4 - Take the opportunity to board out the loft space. Use stilts and dummy joists to lift the boards above the insulation.

During the summer, Wickes have offers of 3 for 2 on insulation and on boards, so it might be worth waiting until then. Look for bargains. If you do board the loft, make sure there's a ventilation gap under the boards. A bit expensive but I used the loftzone floor kit.
