Weather sealing your home
Even if your home is well-insulated, heated or cooled air can leak in and out through gaps and cracks. Air leakage accounts for 15–25 per cent of winter heat loss in buildings. Sealing your home against air leaks is one of the simplest upgrades you can undertake to increase your comfort while reducing energy bills and greenhouse gas emissions.
Weather sealing your home is an easy and cheap way of reducing your energy bills. It can save you up to 25 per cent on your heating and cooling bills and is easy and affordable to implement—even for renters.
When to act?
Many Australians will only think to seal their homes before winter sets in, but air leaks are year-round issues. In winter, air leaks allow hot air to escape and unwanted external cold air to enter and in summer, the reverse occurs. Sealing your home will minimise the need to heat and cool your home from the extremes of the Australian summer and winter, which will reduce your contribution to global warming. In Australia, households produce around 20 per cent of Australia’s total annual greenhouse gas emissions, of which heating and air-conditioning account for around 27 per cent. Draughts can account for up to 25 per cent of heat loss from a home. Weather-sealing can be very effective and many draught sealing measures are inexpensive and easily done yourself.
Putting it to practice
The first step to passive design and sealing your home is to seal the gaps and cracks. They’re often found around doors and windows. For a quick, easy option for filling gaps around door architraves and along skirting boards, pick up some gap filler and a caulking gun from your local hardware store.
The next step is installing weather seals (or draught stoppers). There are a number of different products on the market including flexible strips that attach permanently to the bottom of your door. Fitting a weather seal to your window or door may also help eliminate or minimise problems such as light, sound, dust, draughts, wind, rain, insects and rodents. It seals the gap and acts as a barrier to anything trying to creep through, blocking out the heat or cold and other pests.
Available in a range of colours and materials to suit any kind of door and floor surface, an internal door seal will dramatically improve the functionality of your door by minimising the amount of light, sounds and draughts from other areas of your home.
To further protect your home from heavy rainfall and strong winds, Window Perimeter Seals are easy to install and come in a variety of sizes.
Filling Internal gaps
Increase the energy efficiency in your home by installing easy-to-use gap fillers. They have been developed to easily manoeuvre around corners and come in a range of sizes to suit your needs. Gap Fillers offer even further protection as they are moisture resistant and highly durable.
Install a Weather Seals to suit your front or back entry door and minimise the effects of external elements such as wind, rain, light and sound on your home and its contents while improving the energy efficiency in your home.
Where to start
When fitting a weather seal to your home, the best places to start are:
- In your roof area and underneath your home, check that all openings for pipes, ductwork, and chimneys are well sealed.
- Look for gaps where pipes and wires pass through floors and walls and check for air leaks along the edge of the flooring and around door frames.
- Seal gaps between floorboards.
- Outside, look for any cracks and holes in the mortar and foundations.
- Inspect windows and doors for air leaks.
- Check around exhaust fans, ceiling mounted ducts, wall vents or vented skylights.
- Seal off unused fireplaces.
