Modern heating, insulation and glazing make houses cosy in winter. But those same features can trap heat in the summer, making it unbearable. And overheating isn’t just about discomfort — it affects health, sleep, energy bills and long-term wear on home furnishings too.
If you’re struggling to cool your home without blocking light, these tips can help you ensure your home is flooded with light but without the heat that can come with it in the warmer seasons.
Window Film
Large windows let in daylight and warmth, and for the most part, this is perfect and exactly what you want. But when temperatures rise, this heat can become unbearable. Window tinting is the answer to this problem.
The film doesn’t darken a room like blinds can, and once it’s applied, you can still enjoy the natural light flooding the room, but you can also relax knowing that UV rays are being blocked and your home feels more comfortable.
Add External Shade
Shutters, overhangs, awnings or exterior blinds block high-angle summer sun before it hits the glass — this is far more effective than relying on indoor curtains to shield your home.
Even simple awnings or a strategically placed pergola can cut heat inside dramatically while still letting light seep in. Your home stays bright while the heat is blocked from entering, and you get shade from your external fittings.
Ventilate Smart
Heat gets trapped in airtight, well-insulated homes. And while this is perfect for winter, it’s not ideal in summer. Simply opening windows when it’s cooler at night, or early morning/late evenings helps cooler air flow into your home. Close them before temperatures rise to block the warmer air coming in, and open doors or windows at different points to benefit from cross flow through the home. This will help flush out warm air and provide instant cooling. If you place a fan by an open window, angle it to push cooler air coming in into the property to distribute it more thoroughly.
Decorate for Cooler Rooms
Light colours in rooms that attract heat can be your best friend here. Let’s say you have floor-to-ceiling glass windows and doors in a south-facing home. This will be a natural sun trap. Light wall colours here can be the perfect way to reflect light and avoid heat being absorbed. The same goes for furnishings, too — dark rugs will attract and trap heat, as will heavy curtains. Choose lighter, breathable materials that help the house shed heat and not retain it.
Don’t forget the placement of furniture too— place seating in spaces that aren’t in direct sunlight or can be moved to a more cooler space, i.e. a dining table against a window that has blinds to shut out heat or in a corner the sun doesn’t reach.
Light is what makes the home feel good, but when the light brings heat with it, it can turn a cosy spot into an uncomfortable fast really fast. Shading, glazing, smart ventilation and furnishing choices are all easy ways to combat heat and help you stay cool at home.
