We had a chat to Paul Vujcich, Managing Director for InsulPro, who has been working
with insulation for the past 15 years. Read what he has to say below.

What are the most important factors to take into account when choosing insulation?
Insulation is a key factor in creating a better living environment in your home. The important factors are focused on ensuring that the insulation solution results in a warmer and healthier home for you and your family.
Choosing a sustainable product will enable you to make a positive contribution to
protecting the environment. At InsulPro we produce our insulation from recycled polyester, PET, this is the same material that plastic bottles are made from. We buy fibres that are extruded from chipped up bottles and manufacture these into ceiling and floor insulation for your home. Plus our products are fully recyclable so any offcuts left over from an installation can be re-used in our manufacturing process – so in a nutshell our products are 100% recyclable.
To ensure a healthy home environment we recommend that you choose a product that
is safe and comfortable to touch and feel, and free from such things as insecticides and glues. At InsulPro our insulation solutions, NOVAtherm Ceiling and Wall Insulation and NOVAfloor Underfloor Insulation, are made from 100% polyester which is bonded together using heat not glue.
Imagine the soft touch of your polyester duvet inner; well our insulation product is made of the same material. So you won’t be left with an irritating feel on your skin when you handle it, making it safe and easy to install. Also polyester is a not a protein so we don’t have to treat it with insecticide to stop it being eaten.
Insulation is an investment in creating a healthy home for future years; therefore you should consider how quickly it will or will not deteriorate over its lifetime and how long it will last before you need to replace it. Insulpro products will perform for 50 years; so from the day it is installed correctly and adequately protected, we will guarantee that in 50 years time it will still be performing!
The Building Code in New Zealand requires that insulation meets certain criteria which cover durability, internal moisture, hazardous building materials and energy efficiency. You need to ensure the insulation you choose meets building code requirements. Products that have been BRANZ appraised provide you with assurance that the insulation product has been tested to meet New Zealand conditions which includes the Building Code. Our NOVAtherm and NOVAfloor insulation products both have BRANZ appraisals.
Another vital consideration is the quality of installation for insulation as any gaps in the insulation will dramatically affect its performance. We would recommend that if you are installing NOVAtherm and NOVAfloor insulation products that you use one of the InsulPro approved installers to ensure you create a better environment in your home.
Underfloor insulation is exposed to moisture. It is important that the insulation you choose does not absorb moisture as this will affect the life of the product and expose your home to potential moisture damage.
How can people determine what the best type of insulation is for their homes?
Insulation is commonly made from polyester fibres, wool, fibreglass macerated paper or polystyrene. The best type of insulation should be safe, healthy, easy to install and durable.
If your house was built before 2000 you are eligible for up to $1,300 (or 33%) subsidy toward the cost of ceiling and underfloor insulation under the Energywise Warm up New Zealand:Heat Smart programme. It runs over 4 years from June 2009. If you have a Community Services Card you can get 60% funding towards the cost of insulation.
The Energywise programme includes a list of approved products so if you are taking part in this scheme make sure you select a product that is on the list. For further information visit the EECA Energywise website http://www.energywise.govt.nz
What are the main benefits of installing it?
Insulation creates a healthier, more comfortable home environment.
In winter a cold, damp building can promote mould and mildew, which can lead to asthma, recurring colds and flu. Insulation keeps a home’s interior warm and dry in winter, creating a better environment in your home.
While keeping the cold out in winter, insulation keeps the heat out in summer for a more comfortable temperature indoors. This is an increasingly important consideration as more homes are installing heat pumps and air conditioning units.
Insulation has a vast return on investment which includes such things as providing a healthier home, reducing the strain on the country’s health system and assisting with the resale value of your home as buyers look for warmer homes. It can also save significant money in energy in an environment where the cost of power continues to increase.
Effective insulation in the ceiling can cut heat loss from a building by over 40%.
Insulation in exterior walls can cut overall heat loss by roughly one quarter, and by using insulation in internal walls around living spaces the amount of energy required to heat them will be reduced too. Insulating under floor boards can dramatically improve heat retention even further, as well as cutting out uncomfortable draughts.
Superior insulation will absorb noise to create a quieter living environment, reducing
surrounding noise pollution from the likes of neighbours and traffic.
There are minimum requirements for insulation in the building code. Should homeowners give serious consideration to exceeding those? What are the benefits of doing so?
Yes, we would definitely recommend a homeowner exceeds the Building Code requirements as the home will be more energy efficient, warmer, healthier and will create a more rewarding and comfortable living environment.
And will savings on heating make this an efficient decision in the long term?
The price of electricity continues to increase. In fact a number of power companies are increasing their prices on the 1st of April, after only increasing them in October with the introduction of the Government’s Emissions Trading Scheme. Exceeding the Building Code requirements will mean that your insulation will work harder for you, making you less reliant on using electricity to create a warmer home in winter and a cooler home in summer.
But it is not just about the dollar savings, it is about creating a healthier home for your family and removing the cold damp air in winter time which reduces the incidence to colds, asthma and flu. While in summer time you will have a cooler home.
