Insulating the Loft and Attic

Floor insulation
When converting a loft to a storage or living area, it is not essential to insulate the floor. In fact in some cases it might be a disadvantage. But if you are using the space for storage only, insulating the floor will certainly save on heating bills below, even if the walls or rafters are insulated as well. So before you plank or floor the joists, give some serious thought to the insulation of the floor. The most popular methods for floor insulation are the laying of polystyrene granules or fibreglass blanket in between the joists. You might like to consider a third alternative-installing a false ceiling below.

This creates a layer of still air, which is the best insulation of all. A false ceiling, although it entails more work, is particularly attractive if you have high ceilings as it will lower the height of the room. A false ceiling can be constructed quite simply with aluminium angle strip and insulating boards. In any case, if the roof insulation is to be at all efficient, part of the floor will have to be insulated. This is at the edges where the joists and the rafters meet at the wall plate. Cold air entering up through the cavity wall or blowing in through the eaves can ruin an otherwise perfect job. In this area it is best to lay several layers of glass fibre blankets, covered if possible with sheet polythene or aluminium foil, to stop the draught and seal off the cold zone.

Wall insulation

Whether you intend using the loft for storage or living, you will have to insulate and weatherproof the walls (the spaces between rafters). It must be noted that in all probability you will have to do some restructuring of roof timbers, and strengthen the joists, and it would be pointless to insulate the walls before this has been done. Wall insulation has been included here for convenience. The rafters of most modern houses are covered with roofing felt before the roof tiles are laid.

The felt not only prevents rain and snow from getting into the loft, but also provides better insulation by preventing draughts. If, however, your rafters are not covered, and the tiles or slates are visible from inside your loft, then this is your first job. It is obviously impractical for a home handyman to remove all his roof tiles in order to cover the rafters with felt; anyway this is not necessary. The felt – membrane can be placed in position from the inside. The felt is held in position with tacks or drawing pins, and if a little plastic compound is applied to the side that is secured to the rafter, the seal should be perfect. Always start at the top and work down. Apart from the convenience of pinning the felt at the top and allowing it to hang down while you continue fixing, any overlap will mean that if rain should enter through a loose tile then it will run down the felt and not be funnelled into the loft space.

There are many methods of completing the insulation of the walls. One is to completely line the rafters with a good lightweight building board such as fibreboard or, even better, a plasterboard with an aluminium foil facing. The foil side should face outwards, to deflect back heat in the summer and the cold in the winter. Insulating blanket can also be used. This is attached with battening and, if you decide to board the walls later, the boarding can be nailed to the battening, providing a double layer of ‘space’ sandwiching the blanket and giving excellent insulation. Between the rafter spaces, insulating material such as fibreglass blanket, solid blocks of mineral wool or cork 50mm thick, or flame retarded foam polystyrene can be fitted. With this method, some means of holding the insulation material in place must be devised. It is ideal if you are going to board the rafters over, and do both jobs together.

Kitchen and Bathroom Refurbishment London

The first thing you’ll need to know is exactly how much money you can spare to refurbish your kitchen and bathroom. Once you have a good idea of your resources and how much everything will cost you should look at the kitchen as it is, and decide what initial jobs are essential. For instance, the plumbing may need replacing. Even if the pipes are quite sound, you might want to have the sink somewhere else and so the plumbing will have to be altered.

Remember, the position of the sink should relate to where other fittings are placed, so that the complete kitchen layout will facilitate an efficient flow of work. Next, have a look at the wiring. In an old house this may need replacing altogether. Even if this proves to be unnecessary, you will almost certainly need to install new power points. One of the drawbacks of old houses is that the number of power points provided often only one to each room-is not enough to take the number of electrical gadgets that are commonly used in the modern home.

Don’t install power points at skirting board level. In a kitchen, power points in this position will cause you to do a lot of tiring bending down. Also, when all the fittings are in place, the points will be difficult to reach at all. Shoulder height is about the right position for power points. If your kitchen suffers from damp, this will have to be seen to before any electrical points are installed. Once all the necessary alterations have been done to the plumbing and wiring, you can go on to plan the kitchen conversion according to the considerations outlined below.

Planning the renovation

When planning the redesigning of your kitchen or bathroom, the first thing you’ll need to do is to use kitchen and bathroom design software or make a scale drawing of the floor area of the kitchen. A scale of 1: 10 or 1: 15, depending on the size of the room, should be about right. With the drawn up floor plan, you’ll find it easier to design the layout and positioning of the furniture and fittings. The final kitchen layout should not only result in an efficient work flow being achieved, but should also make the best possible use of the size and shape of the room. The size and shape of the kitchen will go a long way toward determining the type of furniture and fittings that you choose.

How much cupboard and drawer space you can afford,as well as the total area of work surfaces, will be governed to a large extent by the room’s size and shape. Remember that the height of the room, including such things as angled walls, should be taken into account as well as the floor area. If your kitchen or bathroom is on the small side, or is an awkward shape, you’ll have to compromise a little. Some items, while being desirable in themselves, may have to be dispensed with for.

London tradesmen

You could get a London Building Company to carry out the refurbishment or you could employ the tradesmen separately. However, it is a lot easier to deal with London Builders than with the electrician, plumber, decorator, kitchen fitter and bathroom installers.

London Olympics builders

A gagging order preventing businesses which helped build London’s Olympics venues from promoting their involvement in the 2012 games has been lifted after the government paid the British Olympic Association £2m.

The BOA estimates that thousands of companies, which had been frustrated by bans on associating their names with the summer Games, will now benefit from the “stardust” of an event rated one of the most successful in Olympics history.

Loft Conversions in London

Loft Conversion

The space in a loft or attic can be typically 30% of the total floor area of your home. In almost all cases it is wasted space that can be turned into living space. If the attic is used for storage there is no need to lose all of this storage space as some attic space can be retained. Loft conversion or roof conversion is often cheaper than extending your home outwards and potentially increase the value of your property by 10% to 20%. In addition you often do not need planning permission for a loft conversion or basement conversion. It may be possible to complete the work without removing the existing roof covering or making any major structural alterations.
