How Metal Roofing Insulation Can Significantly Lower Your Energy Costs?
Metal roofing insulation is achieved by many different ways. While some are better than others, you will save money on energy costs regardless of which metal roofing insulation system you use. One of the better styles of metal roofing insulation is to use Low-E Reflective Insulation.
Why is this a better system?
Primarily because the Low-E reflective method of insulation saves more energy expenses. The insulation material has a lower R value, but that isn’t by itself a major advantage. What matters more is that over 95% of the radiant heat is reflected away from your building by this insulation material.
The nicer part is that any heat from within your building is similarly reflected back inside, saving you heating or cooling expenses. Low-E keeps your home warmer in winter and cooler in summer. Quite a few householders have claimed a lowering of energy bills by 20% to 30% after using this metal roofing insulation system.
The reflective insulation material has a thin layer of polythene that is sheeted between two layers of 99% aluminum. The insulating material has a Class A fire rating, which adds further protection to the building. By reflecting away heat, this adds to your building’s R value as well. This helps save on energy consumption to cool or warm up a room.
Most metal roofing insulation is made up of fiberglass. This acts to store heat, soaking up heat from within the building and then releasing it back when the temperature drops. Think of it like a battery that stores power only to gradually radiate it back into the room.
Insulation material of all kinds reduces the circulation of hot air within any room. But this lack of free movement of air itself creates a problem when the saturation point is reached. This is when your radiation system breaks down and releases stored heat back into the room.
To make up for this extra heat, your air conditioning systems consume more power to work harder. But by adding Low-E Reflective metal roofing insulation, you’ll be able to prevent the heat from reaching the fiberglass layer itself. That heat will get reflected back into the room, or kept outside it. That way, the fiberglass material doesn’t get heated, and so the amount of heat radiated back into the building is less.
Insulated metal roofing attacks the problem at the most effective level. The roof is one of the areas of your building most prone to radiate back heat or lose it through the extensive surface area. By insulation your roof well, you can enjoy a much cooler home. Lesser use of air conditioning saves you money on energy bills.
You can install metal roofing insulation in different ways. In one method, the insulating material is laid under plywood or ASB substrate. In another, the Low-E material is draped between rafters, and below a metal roofing that is laid above it. The third method is to apply tab insulation once the roofing construction is finished.
Metal roofing insulation can be a complex and controversial topic unless you do your research well and correctly identify systems that will reduce heat transfer in and out of your home and save you money on heating and cooling energy consumption.
