Why insulate the attic floor?

Heat rises – to prevent unnecessary heat loss, one of the most financially rewarding energy efficient measures a home owner can take is to insulate their attic. If modern guidelines are followed a 150mm layer of insulation should be placed between the timber joists running across the attic floor and another 150mm should be placed above this in a crossed format. e.g. If the layers between the joists are layed east-west the crossed 2nd layer would be layed north-south. Any more than this total 300mm insulation depth would be almost overkill as the effectiveness of additional insulation would be minimal and not likely to be cost effective.
There are those out there who would like to insulate their attic space, especially after a winter of freezing pipes and water damage. There is a worry though that the information they are getting is not sufficient. Insulation stops a transfer of temperature from one space to another. When we insulate we normally want to prevent heat from passing into the attic or out through our walls.

Therefore, to insulate the eves or ceiling of the attic is an exercise without much need or merit. The only time a person would normally do this type of work is if:- they have already fully insulated the attic floor to prevent heat rising into the attic space they have fully insulated all pipework and tanks in the attic which may now experience lower temperatures in winter due to less heat transfer from the rooms below. or they are about to convert the attic into rooms and need to insulate against heat loss through the roof they have received advice from an industry professional stating that it would be advisable to do so for example if it was the only option available to to the design of the house
