The Best Way to Tackle Thermal Gains and Keep Heat Out of Your Home.
To tackle thermal gains and keep heat out of your home, you can try the following methods:
A practical heat-control plan combines measures that limit heat before it reaches the building with features that help release warm air. External shade, insulation, glazing and ventilation each address a different part of the problem.
- Insulate your home: Proper insulation can prevent heat from entering your home, reducing the need for air conditioning. Consider adding insulation to your walls, roof, and floors.
- Install exterior shading: Exterior shading, such as awnings, canopies, or opening and closing louvre roof systems, can block direct sunlight from entering your home, reducing the amount of heat absorbed by your windows.
- Use window coverings: Window coverings such as blinds, shades, or curtains can help to reduce the amount of heat entering your home. Consider using reflective or insulated window coverings for the best results.
- Install double-paned windows: Double-paned windows can provide an extra layer of insulation, reducing the amount of heat entering your home.
- Seal your home: Check for air leaks around your doors, windows, and other openings, and use caulk or weatherstripping to seal them.
- Use ventilation: Proper ventilation can help to keep your home cool by exchanging hot air with cooler air. Consider using fans or opening windows to promote air flow.
Why External Shade Matters for Thermal Gain
Australian passive-design guidance recommends stopping unwanted summer sun before it reaches windows and walls. An adjustable louvre roof can shade an outdoor area and nearby glazing during hotter conditions while still allowing light and airflow when the blades are opened.
Unlike permanent overhead cover, an open-close louvre roof can be adjusted as the sun’s height and direction change. That flexibility helps you balance shade with daylight rather than blocking useful winter sun throughout the year.
Coordinate Your Cooling Measures
An outdoor louvre roof works best as one part of a broader heat-management plan. Pair exterior shade with suitable insulation, sealed gaps and well-timed ventilation, and use internal blinds or curtains as an additional layer rather than the first line of defence.
A patio roof that opens and closes can also release warm air from the covered outdoor area. Adjust the blades as conditions change, so the space can respond to heat, shade and airflow throughout the year.
By combining these methods, you can effectively reduce the amount of heat entering your home, helping to keep it cool and comfortable, and reducing your energy usage and costs.
For the right result, consider your home’s orientation, window position and local conditions when planning external shade.
