Proper roof insulation for your home can make the difference between increased energy-efficiency and wasting money.
The way it is installed and the materials used are essential. That’s because different insulation materials have different properties.
However, it seems that many people don’t fully understand how insulation works – the facts and the theoretical principles involved.
In the following lines, we’ll shed light on some of the basic facts about roof insulation that will help you understand the process a lot better.
Knowing these aspects will help you make more informed decisions when it comes to insulating your home.
How Insulation Works
The principle of insulation is closely connected to heat flow, which includes three basic mechanisms:
- Conduction. Conduction is how heat moves through materials. Think about when you’re pouring hot tea in a cup and it gets hot as well.
- Convection. Convection is linked to different air densities and their function. Warm air is less dense, so it rises, while cooler air sinks.
- Radiation. Radiation refers to heat travelling in a straight line and warming up any solid material that absorbs energy.
Most common insulation materials work by slowing conductive and convective heat flow (to a lesser extent).
This means that significantly less heat will be lost in the cold season. Also, warm air will be reflected in the summer, thus reducing radiant heat gain (in the case of radiant barriers and reflective insulation systems).
Different Types of Insulation Materials Explained
Before looking into the different materials, you’ll have to establish a few aspects. For example, what are the parts of your home that you want to insulate?
This is important because some materials perform better than others, especially in the case of roof insulation.
For example, mineral wool can be used for insulating unfinished walls, including foundation walls. However, protective gear must be worn when installing it.
Polystyrene is another option. It can be used on unfinished walls, ceilings and even on unvented low-slope roofs. Still, it does pose certain environmental concerns.
If you’re looking for another insulation alternative that can be used all over your house, you should try multi-foil insulation.
Its properties will make your home more energy efficient, thus helping you save on heating and cooling costs.
It’s also convenient for self-builders because it’s very light, thin and easy to install.
Why Is Roof Insulation Important for Your Home
Physics teaches us that heat rises. This means that an un-insulated roof will cause as much as 25% of indoor heat to be lost.
Over time, this can amount to significant energy costs, costs that you could have avoided. Insulating your roof using high-quality materials is a simple and effective way to reduce heat loss, lower your heating bills, and increase comfort.
Using SuperFOIL SF40 gets you multiple benefits, thanks to its properties:
- It’s thin;
- Has a high R-value;
- Uses 37 layers for increased efficiency;
- Achieves nearly 70% higher performance than standard multi-foil.
