Ventilation is one of the least expensive and most energyefficient ways to cool a building and the people inside it.
Ventilation works best when an appropriate number and combination of vents are used to avoid heat buildup in your home. Air movement is the most important way to expel heat. Evaporation of perspiration is an effective way to cool people. It requires air movement and moderate to low humidity.
Air movement cools your home by carrying heat out of the house as warm air and replacing it with cooler external air. Moving air can also carry heat from cooling systems such as air conditioning ducts to reduce its heat lead and possibly reduce energy consumption.
Well-ventilated and insulated roof spaces form a buffer between your home and the hot outside air. It might also help reduce your use of air conditioning.
Ways to prevent or reduce heat
- Install ventilators on roof space attics, living area and sub floor area
- Use light coloured roofs to reflect heat
- Install ceiling insulation such as Bradford Gold Battsntrade; (insert link to page) to decrease heat transferring from outside to your home
- Keep doors closed when cooling a central room, especially doors of rooms that arennrsquo;t used so the room will cool quicker
- Limit the amount of sunlight coming directly into your home during the hottest hours of the day by keeping your shutters, curtains or blinds closed
- Install screens on windows and doors so they can be left open to allow air circulation, whilst preventing insects
- Avoid using heat generating appliances such as stoves, microwave ovens and vacuums during the hottest hours of the day
- Enjoy the summer nights by cooking outdoor BBQnrsquo;s instead of cooking inside
- Paint external walls a lighter colour to reflect heat or even a quick early evening hose down of hot bricks and tiles will slow transfer through your walls and roof
- In absence of an air conditioner, placing a large bowl of ice in front of a fan giving you instant cold air!
Ventilation to control heat
Adding Bradford Ventilation vents to the roof is an inexpensive and simple way to let that hot air escape, and help your insulation and air conditioning work more effectively. Insulation does a great job of slowing down the transfer of heat between the roof space and living space in your home.
But on hot days heat can still build up over time. When you consider that the heat inside your roof can reach up to 70 C, you can understand the tough job that insulation has to do. If you also have ducted air-conditioning running through your roof space, it is also having to fight against this hot air whilst trying to deliver cooler air into your living areas.
In order for the vent to work properly, fresh, cooler air needs to be able to enter the roof space. Bradford Ventilation also manufactures a range of under eave vents for this purpose, as well as internal closeable ceiling grilles to help release the hot, trapped air from within your house as well.
