Ceiling Insulation – A Complete Guide

Your ceiling is the most important area to have insulated. Here’s everything you need to know.

There are three major areas of your home which should be insulated: ceilings, walls, and floors.  These areas all play a significant role in keeping your home warm, dry and energy efficient. Because heat rises, ceilings are obviously considered the most important area to ensure insulation is up to standard.

Why is ceiling insulation so important?

Over one third of a home’s heat can be lost through an uninsulated ceiling, around 40%. This is a significant amount of heat loss which can easily be prevented through effective insulation. If you are working on improving your home’s insulation or adding insulation for the first time, the ceiling is the most efficient place to start. The results of properly installed ceiling insulation are twofold. Firstly, it creates a barrier to prevent heat from rising out of your home when it is cold outside. Secondly, it also blocks heat from the sun entering your home during in the warmer months. This means your home can stay closer to the temperature you need, saving you money on expensive heating and cooling.

What type of insulation should I use?

There are several types of insulation that you can use in your ceiling. The two most popular are glasswool and polyester. Both materials share characteristics including being energy efficient, non-toxic, vermin resistant and non-allergenic. These are great choices for your ceiling as they are both self-supporting with premium longevity.

Fibreglass insulation is the most popular choice for insulation in New Zealand due to the relatively low cost. Our choice of glasswool insulation is Earthwool due to its superior quality and sustainability. In short, it is non-combustible, recyclable and bio-soluble.

Polyester insulation is the preferred choice for those who want superior noise-cancelling and noise absorption. Polyester has many of the same benefits of fibreglass, but it is thicker and does not contain any breathable fibres.

How do I know how effective my ceiling insulation will be?

The effectiveness of insulation products is measured by an R-value. There are different minimum R-value requirements depending on where you are in the country. In the central plateau, the minimum R-value required for insulation is R 3.3. Ensure that your insulation meets the minimum requirements before installation. At Bay Energy, we use products from Mammoth and Knauf Insulation which have several ceiling blanket insulation options higher than the recommended R-value.

How do I find out if my ceiling insulation is up to standard?

If you are unsure whether your home has adequate ceiling insulation – it is important to talk to the experts. Insulation is an investment in the health and energy efficiency of your home, so expert guidance can help you to make the right decisions.
