WHY INSULATE YOUR HOME?
Benefits of Home Insulation
Increased Comfort
Insulation ensures your home stays cool in the summer and warm in the winter, reducing the need to overwork your heating or cooling systems. It creates an ideal environment for efficient, year-round comfort with less effort.
Reduced Energy Costs
Without proper insulation and sealing, your home may be wasting up to 15% more energy on heating and cooling. It also means extra wear and tear on your heating system and air conditioner. Proper insulation is key to preventing energy waste and keeping both your home and your energy costs comfortable.
Quieter Living Space
Whether you have a snorer, noisy neighbours, or live on a busy street, insulation can help. While it may not block all noise, it significantly absorbs sound, making your home a more peaceful retreat.
Positive Environmental Impact
By saving energy, you’re not only improving your home but also benefiting the environment. Upgrading your insulation is a powerful way to boost your home’s energy efficiency and reduce its carbon footprint.
Higher Resale Value
Thinking of selling your home? Highlighting high-quality insulation as a feature can be a strong selling point, showing potential buyers they’ll save on energy costs in the long run.
Is insulation really worth it?
Let’s take the argument out of the conversation and talk about some simple figures and facts.
A few stats:
- Insulating your home can cut 30% of the energy needed to heat it. Some sources mention 50%. A smart investment? You bet!
- A whopping 500,000 NZ homes are estimated to have inadequate insulation. Stats.govt. data (31 March 2020) estimates there are 1,787,900 households in Aotearoa. That’s roughly one in three homes sheltering a cold family!
- Families living in insulated homes had fewer sick days and doctor visits, according to the Wellington School of Medicine.
- The WHO recommends inside temperatures of at least 18°C; higher if there are young children around. They also state that indoor temperatures below 16°C increase the risk of respiratory disease.
But it’s not just the cold. It’s also the damp and the mould and the condensation. We haven’t mentioned the summer heat. Uninsulated, a third of your home’s heat is lost through the roof, a third through the floor, and a quarter through the walls.
Many homeowners try to fix these temperature issues with heat pumps or dehumidifiers. What we’re really doing is adding more and more and more heat… to a leaky box. It’s the old bucket with a hole story. The short and the narrow is that you’re putting a plaster on a wooden leg. What you have is a sieve, and plugging is what it needs.
But with what?
How does insulation work?
The answer to this question boils down to how insulation works. Here’s the deal:
All materials allow heat to pass through to some degree. By nature brick, plasterboard, glass, and metal do a poor job at keeping the heat in. It’s common sense to resolve this issue by simply adding an extra layer of material that does an outstanding job where building materials let you down. That extra layer is an ‘insulator’.
How well an insulator performs is measured by R-value. The higher the R-value, the better the insulation. Fibreglass, wool, cardboard, polyester, and polystyrene all have a high R-value and do a great job at insulating. So how much ‘R’ is good enough?
The Building Code describes the minimum R-value you need for your ‘climate zone’. It makes sense that the balmy North can get away with a lower R-value than the South with its freezing winters.
The idea is to insulate like a thermos or a chilly bin: ceiling, wall, and floors.
Insulation Costs
As a rule of thumb, the higher the R-value, the more it will cost. But also the more effective the insulation will be. So how much is enough? The short answer: as much as your wallet allows. The better your home is insulated, the cheaper it will be to heat. Over time, it’ll be worth it.
Which insulation is best in New Zealand?
But how to choose the best insulation for your home? The options are extensive, to say the least.
Different uses require different products. Different materials have different perks and downsides. And then there is the matter of personal preferences or priorities. We know… it’s complicated.
Is it your ceiling or the walls (or both) that need padding? Do you want your choice of insulation to be asthma friendly? Environmentally friendly? Is fire resistance a priority? Or is the budget an all-overriding factor?
In a nutshell, there are four main materials on the market. All four do a good job and all four come in different sizes and thicknesses. All the Total House product brands are fire-resistant, moisture resistant, and reduce allergies. On top of that, they all come with a 50-year manufacturer’s warranty. (No shortcuts if we have a say in the matter.)
