Energy efficiency

There have been considerable advances in producing more energy efficient consumer goods in recent decades. However, savings in energy can be overshadowed by the sheer number of goods now reckoned to be ‘necessary’ for comfortable lifestyles. Look carefully at the labels when you need to replace a household appliance.

Loft insulation in narrow spaces

George,There is a website dedicated to tri-iso super 9. It is at www.tri-isosuper9.co.uk. They advise that 25mm of thier product provides the same thermal insulation as 200mm of rock wool, the standard insulation material. The guidelines are for 250mm of insulation, but actually the difference between 200mm and 250mm in terms of heat retained is very small. As most lofts have at least some insulation I would suggest that a roll of 25mm deep tri iso super 9 would comfortably meet the recommended insulation depths. I haven't done a price comparison, though I suspect your traditional rock wool will be cheaper.
