Floor Insulation

Welcome to our exploration of the innovative usage of blown insulation for insulating the underfloors and midfloors of New Zealand homes.


Can you use blown insulation to insulate your floors?

Blown insulation can be used in a wide variety of floor applications, offering a flexible, efficient solution for both new builds and retrofits. Here are some of the key applications:

Underfloor Insulation:

One of the primary applications of blown insulation is in the underfloor space of houses. By placing a retainer product known as a Blown-In Blanket (BIB) on the underside of the floor joists and blowing insulation between the joists, you can achieve comprehensive and uniform coverage that significantly reduces heat loss.

Midfloor Insulation:

Blown insulation can be used to insulate the midfloors of multistorey homes. This can significantly reduce heat transfer between levels, making your home more energy-efficient. The insulation can be installed using specialised blowing equipment, without the need to remove any existing linings.

New Build Insulation:

In new constructions, blown insulation can be used to insulate floors during the construction process. A BIB product can be used in the midfloors of a new build house, providing excellent thermal performance from the outset.

Why use blown insulation to insulate your floors?

Utilising blown insulation for your floors can significantly enhance your home’s comfort level and energy efficiency, offering unparalleled advantages over traditional polyester-type products.

Firstly, blown insulation provides a higher R-Value – a measure of thermal resistance – than traditional products. This means that blown insulation better resists heat flow, keeping your home warm in the winter and cool in the summer. Given New Zealand’s diverse climate, a higher R-Value can significantly contribute to a home’s comfort and energy efficiency.

In addition, there are now new insulation systems such as Warmafloor Insulation, specifically designed for underfloor insulation, using a retainer product known as a Blown-In Blanket (BIB). This system involves placing the BIB on the underside of the floor joists and then blowing insulation in between the joists. This ensures complete and uniform coverage, something that can be hard to achieve with traditional insulation materials.

When it comes to midfloors, blown insulation presents a game-changing solution. It can be installed using specialised blowing equipment, without the need to remove any existing linings, making it an ideal retrofit insulation solution. In new builds, a similar BIB product can be used to retain the insulation before the internal linings are installed. 

The primary benefits of blown insulation – such as comprehensive coverage, high R-values, adaptability, and quick installation – extend to underfloor and midfloor insulation just as they do for walls and roofs. This translates into improved thermal comfort, enhanced energy efficiency, and potentially considerable savings on heating and cooling bills.

Whether you’re retrofitting an older house or planning a new build, considering the use of blown insulation can make a significant difference in your home’s overall thermal performance and comfort.
