roof insulation types for any homes

Various materials are available for roof insulation. Talk to an ironmonger who stocks a good range, and ask his advice about how much will be needed for your home. Take along rough measurements of your loft-you can measure the ground floor from front to back and side to side as a guide. Arrange to have the packs of insulation on a sale or return basis it is far better to have too many packs and have to return one than to take too few, and have to finish the job another day. Insulating the loft is a job which most people can accomplish quite easily, but it is not a comfortable job, and may involve crouching and bending to reach the furthermost points of the sloping roof. Use a short length of board to balance between the joists, so that you have somewhere to kneel. Never tread in the space between the joists.

Wear your oldest clothes, most lofts are extremely dusty. If you are allergic to dust, wear an improvised smog mask, made from gauze, or a handkerchief. Some form of lighting is necessary if you have no light in the loft, borrow f buy a electric lamp holder on a long flex, which can be plugged in to a light-socket outside the loft. If the entrance to your loft is small, be sure to choose a form of insulation which you will be able to get into your loft. For loft insulation you have the following materials to choose from: Loosefill Granules or pellets of vermiculite, loose mineral wool or glass wool. Loosefill is fairly easy to put down you buy it in bags and pour the granules or pack the loose material into the space between the joists of the loft to a depth of two inches. That’s not as difficult to judge as it may sound, as you use a specially shaped piece of cardboard or wood to level off to the correct depth.

wool blanket roof insulationFibreglass or mineral wool blanket
This is an excellent insulation material, especially if the house is not your own property, as you can simply roll it up and take it with you when you move. The blanket is usually 1-inch thick, though it is also available in 2- to 4-inch thicknesses, giving of course, even better thermal insulation. To lay insulating blanket you unroll it between the joists, tucking any extra width up each side of the joists. It’s a good idea, if you are intending to buy insulating blanket, to first have a look at your loft and measure the distance between the joists. If the joists are set at irregular widths, as may be the case with some older houses, you would be better advised to use one of the loosefills. It is essential that you wear old gloves when you lay fibreglass, otherwise minute fragments of glass may penetrate the skin and produce a most uncomfortable effect.


aluminium foil roof insulationAluminium foil
This involves putting down a layer of thin crumpled foil between all the joists, and then tacking a second layer of reinforced foil over the top of the joists, sealing all the spaces. This method may take longer, and if you will be going up into the loft occasionally and stepping across the joists, it may prove too fragile. If you use the loft as an extra room and have close-boarded the Hoor, you can still insulate the roof. Use either insulating boards, nailed to the rafters and then painted, or reinforced aluminium foil, also tacked to the rafters. There is another method of roof insulation by the use of expanded polystyrene, applied in liquid form. But this is not something you can do yourself.

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 tucked 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.
