Following on from our previous article: “Top 3 causes of heat your home and how to combat them”, we delve deeper into the first type of heating: Radiation!
To refresh your memory, radiation is the transfer of heat through electromagnetic waves. It is how the sun heats the earth and what causes your food to heat up in the microwave.
As mentioned in the previous article, darker colours absorb the sun’s radiation more effectively than lighter colours. Meaning, that a darker coloured roof will gain around 31% more heat than a light coloured one.
Changing the colour or painting your roof will go a long way to reducing heat and is far easier and cheaper than replacing it.
But you can now go a step further than just painting it a lighter shade, with specially designed, heat reflective paint that will reflect much of the sun’s heat. Click here if you would like to know more details about this special paint.
Driveways, paths and concrete patios all soak up a lot of heat during the day which they release slowly overnight. This all adds to how much heat your home absorbs during the day and how quickly it can cool back down when the sun goes down.
Thankfully all of these can also be painted with the same heat reflective paint that will significantly reduce the heat they soak up and store.
Another heat reflective solution to consider if you’re renovating, re-roofing or building is Sarking. Sarking is a reflective foil insulation that repels the suns radiating heat.
Although, if your roof is dark in colour it will still absorb heat and conduct it through the sarking and then heat up the roof cavity. Click here if you would like to know more details about the insulation foil Sarking.
An additional effective solution to minimize your roof soaking up the sun’s radiating heat may be to shade it from direct sunlight. Stopping direct sunlight reduces heat exposure to the walls and roof, lowering the temperature substantially.
You may think that planting trees may take a long time to provide shade and reduce heat/sunlight exposure but there are fast growing varieties that will show results in as little as three years.
Deciduous trees are a good option, as they will provide shade in summer whilst allowing the sun to shine through during the winter.
When planting any trees, but especially a deciduous tree, you should think about how close you plant them to the house.
Will they be over hanging your roof line?
How often are you willing to get up and clear your gutters?
How tall do you want it to grow? And possibly most importantly will their root systems affect any drainage or foundations in the area you plant them?
Once you’ve found the plant that suits your back yard and will provide the shade you look for in summer, don’t wait another day! Go today and plant it, you’ll be thanking yourself in the years to come!
One of the most common solutions people use for an overheated/hot house is cooling it with an AC. Installing a new AC on its own may cool your house to a comfortable 23 degrees but it will eat into your wallet and damage the environment at the same time. So why not look for sustainable, effective and long lasting solutions?
Why not combine your new AC unit with the above mentioned solutions that are not only environmentally sustainable, but will significantly reduce your need for your cooling system and be lighter on the hip pocket?
With so many different homes in as many different locations and environments there is no one simple solution to stop your home getting hot through summer. But by understanding how heat enters your home you can start today to plan what will work best for your home.
Each step you take will not only move you closer to having a comfortable house to live and sleep in, but also to avoid any big surprises on your electricity bill!.
Do you still have any doubts about the steps you have to take to reduce the consequences of the sun’s heat radiating into your home?
