Using shutters to keep your house cool

21 Dec 2015
Exterior shutters are also ideal for creating an outdoor entertainment space that is comfortable during the day and evening.

When the summer temperatures peak often we become hot and uncomfortable in our own homes. What makes it more frustrating is the fact that keeping our homes cool in summer without the benefit of a costly energy-hungry air conditioner is not a simple open and shut case. 

Karina Palmer, interior designer and marketing director of American shutters, says windows and doors are responsible for a lot of the heat loss and heat gain that takes place in a home, and knowing how to effectively use and treat these is critical for optimum indoor conditions. 

She says if your home is properly insulated, then keeping your windows and doors closed during the heat of the day, and opening them up as the summer temperatures drop in the evening and early morning is good advice. However, she says if your home is not insulated then closing your doors and windows could be counterproductive, creating a greenhouse effect. 

Shutters can also be used to block out unwanted sunlight and heat.

Certain window treatments act as effective thermal insulators, restricting the amount of heat gain and keeping the interior cool. 

Karina says interior wood blinds, when completely closed and lowered, can reduce heat gain by around 45%. They are also effective at blocking or directing the light into a room, she says. 

Shutters are brilliant thermal insulators as their adjustable louvres allow ventilation and light control while limiting the heat gain through windows and doors. 

According to Karina, exterior shutters are top performers when it comes to thermal insulation in summer, providing an effective, attractive barrier between outdoor heat and the window or door glass pane. She says they are also great for added security and do not take up any interior space.

Shutters are an excellent option to get rid of heat buildup from a closed house after a long hot day. Fling open your doors and windows when you get home to cross ventilate, or use fans to expel the hot air if there is no breeze. 

Keep your shutters locked for security and use louvres that are suitably tilted for privacy, and if refuge from those flying bugs that love the light is also essential, fit an insect screen between your shutters and window for ultimate indoor peace. 

Karina says homeowners need to do what they can to stay cool and make the most of the glorious summer weather, because before they know it, they’ll be moaning about the cold and longing for the summer heat again.
