roof insulation loft type | reduce heat lost

About 20 per cent of the heat lost from the average house goes through the roof. So while you are considering your roof you should ponder on how well your loft is insulated. To minimize heat loss, a thickness of 100mm or even 125 mm of insulation called roof insulation loft type in centrally heated homes is today more desirable than the mere 25 mm that was recommended previously. If you insulate your loft or top up the insulation already there you should recover your outlay, by way of reduced fuel bills, in about a couple of years. Although it is an unpleasant task carried out in cramped conditions, doing it yourself will guarantee that the work has not been skimped. Roof insulation loft type is available either in the form of a blanket that is rolled out between the joists or a loose fill material, that you pour from a sack. Both types are equally effective, but in an odd shaped loft with lots of nooks and crannies, it can be quicker and easier to pour out a loose material than to fit blanket. lf you are starting from scratch use whichever you wish. When topping up, it is better to use the type you already have. Take care not to place any load (even a foot) on the ceiling while you are in the loft, or it might break through. It is a good idea to take a plank with you and stand on that. Opinions vary about the clothes you should wear. Some people believe that if you wear as little as possible, you can take a shower afterwards and quickly wash away all the scratchy fibres. Others say you should protect yourself with long sleeved shirts buttoned at the collar, trousers tuckedĀ into socks and sleeves into gloves.

Roll out the blanket, making sure it is well tucked down at the eaves so that wind cannot blow underneath it. If you use loose fill, simply pour it into place. It is, however, surprisingly easy to misjudge the depth to which you have filled a gap, so make a gauge from a length of wood with a notch cut out of each end of the lower edge to form a T with a short stubby descender. The depth of this descender should equal the distance from the top of the joists to the required top of the insulation. Rest the cross piece of the T on top of the joists, and drag it along to spread the granules to the correct depth. A well roof insulation loft type is cold, so make sure the water pipes and tanks are well protected, either with lagging or, if the pipes are low enough, by laying the blanket over them and draping it on top of the tank. Leave the space under the tank clear, however, so that warmth can penetrate up to it from the rooms below, as a further aid to stop it from freezing. One problem with attic insulation is that it can make the loft so cold that condensation develops and soaks the insulation, rendering it ineffective. Most lofts have sufficient ventilation to stop this from happening. lf not, lay polythene under the insulation as a vapour barrier, or install ventilating grilles.
