What Is The Recommended Insulation Thickness

What Is The Recommended Insulation Thickness?

Insulation itself and rules and regulations have changed considerably throughout the past few decades. The demand for insulation is on the rise due to global weather changes. Today, I am going to discuss Insulation Thickness and its importance. The governments suggest every house owner have insulation for attic and walls for global energy saving. Yes, insulation in your home can help the world to save energy. Also, it helps the world lower greenhouse-gas emissions.

Insulation Thickness: The recommended Insulation Thickness for attic has increased over the past few years. But why? It’s dead simple. The thicker the insulation, the more energy you can save. Well, don’t get me wrong here though. I didn’t mean to use 2-3 layers of insulation for better energy saving. I am referring to the thickness of the products. Why do governments change recommended Insulation Thickness anyway? Reducing overall energy consumption in the country is crucial for every government. How much money do governments spend for gas and electricity? They want to save money by reducing overall energy consumption.

There’s a high demand for gas and electricity in today’s world. The heating air conditioning system in your house uses more energy than any other systems.

Insulation Thickness

During the winter, you keep the heaters on for the whole day, and the ACs work hard during the summer. But insulation is our best friend when it comes to maintaining the right temperature in our homes.

Insulation Thickness change over the past few decades: In 1965, the recommended thickness was 25mm. In 1975, 60mm. In 1985, 100mm. In 1990, 150m


m – a significant increase. In 1995, 200mm. In 2002, 250mm. In 2003, 270mm. Insulation manufacturers and installers know all these regulations, and the manufacturers aren’t allowed to produce insulation that is thinner than the recommended thickness.

How can I increase insulation thickness?: If your house is from the 70s, 80s, and 90s; then you may have insulation that is thinner than the recommended thickness today. Anyway, adding additional insulation is not that expensive. But if your old insulation contains traces of asbestos in it, then it is advisable you get rid of all and replace with new insulation. Hire a professional for an inspection. It is safe to assume that your insulation contains asbestos in it if your house is not from the 90s. It’s a big headache, I know.

Insulation Thickness limitations: As I said above, you can’t make it thick as much as you want. I mean, when you add layers of insulation on top of each other; it won’t save you massive amounts of energy. For example, if Insulation Thickness you currently have is 150mm, then making it 270mm would not double the amount of energy-saving.

Installing attic/wall insulation and removal: OK, now you know the importance of it. Bulk insulation and reflective insulation are the two main types available today. Installing bulk insulation is much difficult when compared to installing reflective insulation. Removal and disposing of insulation that contains asbestos is a nightmare. Attempting to do it yourself can lead to you getting asbestos-related health problems. Also, you should know the rules and regulations on disposing of any materials that contain traces of asbestos.
