Thereafter, the movement of people around the house, moving in and out, and naturally opening and closing windows and doors will deal with other ventilation needs.

The bottom edges of front doors can be real hotspots (or should that be cold spots?) for draughts. For this reason, fitting brush strips or hinged flap draught excluders to this section of the door is highly recommended.

Believe it or not, your problem will not be unique — every possible draught has been considered and appropriate products produced. Where to Buy Draught Proofing Supplies I like this product, it works well, and is properly made. However, more detailed instructions should be supplied.

Home ventilation in the form of extractor fans and cooker hoods will ensure that condensation is properly dealt with, at source. Controlled ventilation will reduce condensation, maintain a healthy atmosphere and prevent damp and mould growth by letting in air where it is needed. Draughts, however, let in too much air in the wrong place at the wrong time, making draught proofing the cheapest and most effective way to save energy, and money, especially in older buildings How to Draught Proof Your Home 1. Draught Proofing DoorsBrush strips usually come in the form of a thin metal bar, with the brush fixed to the bottom. These bars can be cut to length and are normally screwed into place. Some are designed to slide onto the bottom of the door before being fastened with screws. You need to ensure that the bristles on the strip reach the floor. His interest in renewable energy and sustainability was first inspired by visits to the Royal Festival Hall heat pump and the Edmonton heat-from-waste projects. In 1979 this initial burst of enthusiasm lead to him trying (and failing) to build a biogas digester to convert pig manure into fuel, at a Kent oast-house, his first conversion project.
