Metal roofing is popular in warm climates and you’ll find that without proper ventilation and insulation, the heat can make your home feel uncomfortable during the long summers here in Athens-Clarke County. However, there are different ways of insulating your home from radiant heat while also making you and your inhabitants comfortable throughout the whole day and night. This is best addressed during the installation of your new roof but can be installed after the fact as well.
Heat insulation has a multitude of different benefits in many situations and conditions. Not only does it make reduce the need for energy consumption, but it also provides more comfort for better living standards. Heal insulation also reduces the requirements for HVAC which stands for Heating, ventilation, and air conditioning since your home will be cooler once you have roof insulation installed.
Roof insulation against radiant heat and retaining heat
As the name suggests, roof insulation is a great way of removing excess heat while also creating a barrier against heat that might penetrate the interior of the house. The most commonly used roof insulation is in the form of the roof insulation foil which has been known to reduce heat build-up during summertime at 97% while also retaining heat inside the house during much more colder seasons.
So what are some of the benefits of roof insulation against warm and cold climates?
- Roof insulation can retain heat during winter by creating a warmer atmosphere inside.
- If properly installed, the amount of electricity that’s being expended to keep homes warm and hot is severely reduced which means less energy expenditure.
- Once roof insulation is installed in larger buildings, the number of HVAC equipment can be reduced which can help save money and space.
- One of the main reasons why mold, rot, and mildew form inside dank homes is because of the build-up of moisture and heat. By maintaining good roof insulation, humidity and moisture are reduced to levels that will stop fungi from growing.
Types of roof insulation
There are two different types of roof insulation why are:
- Reflective insulation
- Bulk Insulation Material
- Blown-in cellulose
- Sprayed foam
- Rigid boards
In most cases, business establishments and buildings bond together both their metal framework and bulk insulation to have a more effective insulation system. When it comes to versatility, the reflective insulation material is a better form of controlling and repelling unwanted heat while also controlling humidity and moisture.
Roof Insulation Material
Reflective roofing is comprised of two layers with the outer layer being made out of aluminum foils that will reflect light back outwards and an inner layer which is either made out of foam, bubble sheets, or even fiberglass. This makes reflective roofings perfect for barns roofs. Reflective roofings are ideal for warmer climates since it reflects off 97% of heat while keeping the interior of the house cool and comfortable.
Types of Bulk Roof Insulation
- Blankets – This is one of the simpler forms of insulation since it incorporates the use of blankets which are made out of wool, fiberglass, and cotton that is layered on the roof. This helps trap heat that might escape while also creating a barrier against penetrating heat as well.
- Rigid Foam – Compared blankets, rigid foams have fewer benefits when it comes to absorbing moisture and humidity. This foam is, however, perfect for close to confined spaces.
- Sprayed Foam – Sprayed foams have a more industrial function as it is used for metal walls and roofs so that it would be sealed off from humidity and leaking. What makes sprayed foams versatile is that it can control condensation well. The only downside to sprayed foams is that it is a bit harder to install than the previous two and professional supervision is needed when installing the foam.
Radiant Roof Insulation
During the peak of summer, penetrative heat outside homes tends to be incredibly high. The best way to protect your home from so much heat is to install reflective roof insulation since the refective foils can easily reflect off excess heat that might become a problem for your home. Moreover, if homeowners also install a reflective blanket right below the attic, it will prove as a second barrier which can significantly reduce energy and electricity costs used for cooling.
Insulation and metal roofs
Metal roofing has been around for decades already and is popularly used in commercial buildings and different types of houses. Even though metal roofing is durable while long-lasting, they tend to warp easily under extreme amounts of heat or become too brittle if exposed to lower temperatures, which makes roof insulation perfect against reflecting out heat or retaining a good amount of heat against colder climates.
All-in-all, there are plenty of different types of insulation that you can choose from but each one is very situational on the type of materials that you are using for your roof. Homeowners have to also keep in mind the shape of their roofs, their architecture, and the climate that is most prevalent in their region.
