Staying warm in wintertime is as much about fighting draughts as heating your home. As much as 50 per cent of heat can be lost through windows, doors, walls and the roof of your home. Many forms of insulation and draught-proofing are inexpensive and easy to install yourself, involving little in the way of time and money for a good result.
Check windows – Gaps between the window frame and surrounding masonry should be filled with sealant both outside and indoors. Windows that are opened should have sealing strips around the edges. For windows that will remain shut, plastic film can be attached to the window frame as a very effective double glazing.
Insulate your loft – See this week’s ‘How to’ for more advice. Cold water tanks – often located in the attic or loft – can be insulated with roll insulation or polystyrene board.
Lag pipes – Hot water pipes running through unheated areas should be lagged. Split foam covering which can be cut to size is easy to use and readily available from DIY stores.
External doors – Fit draught excluders to the sides of the door and the threshold, if necessary. A letter box flap and keyhole cover will help keep draughts down.
Internal doors – Don’t forget that draught excluders or foam strips on internal doors will help keep your home insulated.
Check floorboards – Unless insulated, floorboards can be a major source of draughts in the home. Although it is possible to insulate between the joists beneath the floorboards, this is a major job best tackled when replacing the floor. A simpler option for carpeted homes is to lay sheets of hardboard over the floorboards and run beading around the edge of the skirting board.
Insulate hot water cylinders – Special insulation ‘jackets’ are available for hot water cylinders. Take care not to cover the thermostat or electrical cables. If your cylinder is in an airing cupboard, leaving a pipe unlagged should provide more than adequate heat.
Stop draughts from overflow pipes – In severe weather, overflow pipes can be a source of strong drafts. A simple way of combating this is to cut off the neck of a balloon to make a thin rubber cylinder and stretch this over the end of the pipe. This will allow water to flow through but will close again afterwards, keeping the wind out. Alternatively, fit a pipe flap – available from DIY stores – to the end.
Line radiators – As much as 25 per cent of heat from a radiator on an outside wall can be lost through the wall behind it. Fitting a foil-faced radiator lining to the wall behind the radiator will improve things.
Consider condensation – Remember it’s important to maintain good ventilation in your home, whatever the weather. In centrally heated, draught-proofed homes, rooms can quickly become uncomfortable and stuffy. Condensation can easily build up, causing damp. Make sure that vents and grills are working properly and are adequate for your home’s needs.
