Kia ora! Filmore Foam, here! The R-values required for housing and small building insulation have officially changed as of today – does your new home design stack up?

The new R-value insulation regulations in New Zealand have changed as of today, and homeowners, architects and builders need to take action to ensure that their new home designs meet the new standards.

One of the most effective ways to improve insulation and achieve compliance with the new regulations is through the use of spray foam insulation.

Spray foam insulation is a versatile product that can be used to insulate a wide range of spaces, including roof spaces, walls, and floors. The product is applied as a liquid, which then expands to fill all the gaps and voids in the space, creating an airtight seal that reduces heat loss and improves energy efficiency, excluding cavity filling to existing houses.

Spray foam insulation has several advantages over other insulation materials, especially in the context of the new R-value regulations. Firstly, spray foam insulation has a high R-value per inch, meaning that it provides better insulation performance than other materials of the same thickness. This means that homeowners can achieve compliance with the new regulations without having to add extra layers of insulation, which can be time-consuming and costly.

Another advantage of spray foam insulation is that it creates an airtight seal that reduces air leakage, which can account for up to 25% of a home’s heat loss. The airtight seal created by spray foam insulation also reduces the risk of moisture intrusion, which can lead to mold and mildew growth and compromise indoor air quality.

Spray foam insulation is also a long-lasting product that requires minimal maintenance. Once applied, it can last for the life of the home, providing continuous insulation performance without the need for replacement or additional maintenance.

Overall, spray foam insulation is an excellent product for homeowners who want to achieve compliance with the new R-value regulations in New Zealand. It is a high-performance insulation material that provides superior insulation performance and creates an airtight seal that reduces heat loss and improves energy efficiency.

While spray foam insulation can be more expensive than other insulation materials, the long-term benefits in terms of energy savings and increased comfort are well worth the investment.

Additionally, the government has introduced several measures to help homeowners with the costs of insulation upgrades, including a subsidy scheme for low-income households and a loan program to help finance insulation upgrades.

To ensure compliance with the new regulations, homeowners should seek out a reputable insulation contractor like NZFoam, who specialize in spray foam insulation. We are able to provide a comprehensive assessment of the building design’s insulation needs and recommend the best approach for the job.

NZFoam is able to assist with insulation plans for new builds, and some retrofitting to existing homes. In existing homes, it is often possible to spray in to underfloors and existing roof spaces (with pitches above 25 degrees). Retrofitting existing walls or skillion roofs will require a removal of the plasterboard – so you need to be prepared for a major renovation in this instance.

In summary, these R-value changes in New Zealand represent an important step towards improving energy efficiency and reducing greenhouse gas emissions. Spray foam insulation is an excellent product that can help homeowners achieve compliance with the new regulations while providing long-term benefits for their homes in terms of energy savings and increased comfort.

With the help of a reputable insulation contractor like NZ Foam, building professionals can take action to improve the insulation of their builds and do their part to protect the environment.
