The exterior walls of your house will have to endure all sorts of weather conditions. The exterior walls should stand strong against heat, rain, cold, dust, storms, wind and even snow. To ensure safety and have increased durability, the exterior walls need to be made from sturdy material like brick, or concrete blocks or stone. These materials are eco-friendly, highly durable and low maintenance. You can get the exterior walls of your house coated with weather proof paints and sprays and have a robust exterior in all weathers. You could also use a stone veneer on your concrete walls for the aesthetic effect and yet keep it durable.
