5 reasons why you should insulate your home before winter

Winter is coming! With colder weather just around the corner, it’s time to start thinking about how to keep our homes warm and cosy. One of the biggest factors that help reduce cold air entering your home and keeping the heat in is insulation.

Here are 5 reasons why you should insulate your home before winter.

Good quality insulation will help retain warmth within your home, meaning you won’t need to use your heater as much! Insulation is designed to keep your home cool during the summer, and warm in winter, so that your A/C and heaters won’t need to be used as often. Not only will your energy thank you in winter, but all other seasons too.

Nobody likes those chilly winter drafts. They’re usually caused by holes and gaps that allow cold air to enter your home, meaning you probably have poor insulation. Good quality insulation can help block out those gaps and holes to ensure warm air stays in, and the cold air stays out.

Cold floors make it that much harder to get out of bed during those cold winter mornings! Floor insulation can make a huge difference in making your floors feel warmer and comfortable during winter.

Many homes suffer from freezing pipes in the winter, which is often caused by major air leakage in your crawlspace or basement. This can lead to a pipe burst which can result in expensive repairs. Pipe lagging can help prevent freezing pipes so that it doesn’t burst in the first place.

You’ll want to insulate your home before winter rolls around, as contractors’ schedules’ fill up very quickly in colder months. So, the longer you wait to insulate, the longer you’ll have to put up with a cold home. It’s a good idea to prepare before the winter rush comes along.

Can you install insulation yourself?

So you consider yourself a bit of a handyman? It looks easy right? Just rip off the GIB and throw some batts in the walls and your done – no need to hire an insulation company after all – right?

While a lot of people do attempt to install their own insulation, there’s a few things you should be aware of it you do. It can be tricky business and there’s a few health hazards to be aware off as well.

Choosing the right insulation.

First things first, make sure you choose the right insulation. Are you insulating your roof, your walls or your floors? Are you going to use foam, fibreglass, cellulose, mineral wool or polystyrene insulation? What R rating are you trying to achieve and do you have the equipment necessary to install insulation yourself?

Roof insulation could be different depending on what style roof you have and how much of a cavity there is to deal with. Many New Zealand roofs have large open attics and most people will use a loose fill or fibreglass batts. Installing insulation in your roof is probably the easiest type to do yourself, but it can be a time consuming job and you’ll need to be careful to ensure there’s no gaps in your installation.

Foam is also an option for your roof or walls but it’s a difficult substance to install at the best of times. Foam insulation is essentially is sprayed on wet and it dries into a durable layer of foam. It’s a messy process and can be rather unsightly.

Wall Insulation can also be challenging. If you’re doing this yourself it will probably mean pulling the GIB off the walls and finding the right Batts to put in. It can be a bit of a jigsaw puzzle to try and fit everything in around the frames and joists without leaving gaps, and even if you manage to get it all in place, you’re left with the daunting task of fixing up all your internal walls.

The floors, well that all depends on access under the house. Many people will either leave this one altogether or there’s also an option of fibreglass insulation rolls than can be stapled to the underfloor of your house.

Possible Health Risks when installing insulation.

Many insulation products can be quite hazardous to your health. It’s always important to have the right safety equipment including masks, goggles and a long sleeve shirt.

Some insulation products can contain small particles that can be easily inhaled. They can cause skin and eye issues and possibly lead to respiratory issues down the track.

You’ll also want to be careful about installing insulation around electrical wires and light fittings. If installed incorrectly, it could lead to electrical issues and put you at risk of a fire.

Perhaps you should leave it to the experts?

So in summary, yes, you can install insulation yourself but you need to make sure you know what you’re doing. But really, it’s a far more sensible idea to call an expert.

Can Updating Your Insulation Increase Your Home’s Property Value?

When you’re selling your home, getting the highest offer possible is one of your biggest priorities. Although you can’t control factors like the current mortgage interest rates or the state of the economy, there are a few things you can do to increase the resell value of your home. One of the biggest ways to increase your home’s property value is insulation. If you’ve ever had to rug up with layers to stay warm indoors, you’ll understand why insulation is such a big draw card. Sadly for many of New Zealand’s older homes poor insulation (or no insulation at all) means cold houses.  And unimpressed buyers.

If you’re looking to sell your home for max return, it’s worth noting that insulation does more than just keep your house warm, it helps sell your house.

Here’s a few reasons insulation is worth installing if you’re looking to increase your home’s property value:

An insulated home is usually a well-looked after home

Potential buyers know there’s a good chance a home with good insulation is free of damp, mould or mildew problems.  It’s also a good indication that the owner of the home has looked after the property. Because insulation is integral to your home being healthy (Homes that are poorly insulated, damp, or cold can cause health issues like respiratory problems or diseases like rheumatic fever) and liveable, buyers are more likely to purchase a home that is ready to live in from the get go.

It’s less work for the buyer

While you’re looking for top dollar for your home, often buyers are stretched when it comes to meeting the purchase price. If further costs are involved, like installing insulation, they might be less likely to purchase. Much like the point above, a buyer is more likely to be interested in a home that is ready to live in and isn’t going to incur further costs or work. Installing good insulation before you go to market makes your home more appealing against the competition.

An insulated home is a more energy-efficient home

While insulation might not raise your home value in a visible way, like fresh landscaping or a new kitchen does, an insulated home pays a small return on the investment by lowering  heating and cooling bills. A fully insulated house needs about half the heating of an uninsulated house. Efficiencies in your home also mean there is less waste of valuable resources as reliance on natural resources is minimised.

As well as being a sure fire way to increase your home’s property value as well as helping your house to become more comfortable and liveable. With all the benefits of an insulated house, it has been recognized by the New Zealand government that insulation is compulsory for a comfortable  and As of July 1, 2019, rental houses New Zealand wide are required to be insulated.

Insulate your home

Your home insulation is one of the most important features to consider when you’re trying to save energy. A fully insulated house needs about half the heating of an uninsulated house – that’s huge! Many New Zealand homes have poor insulation or no insulation at all which means higher reliance on heaters and fans in a bid to warm or cool down the house during different seasons. Wall insulation. on the other hand, can help save up to 35% of your homes heat.  It’s also important to inspect and upgrade insulation as Old insulation doesn’t have the same insulative properties as newer insulation. Efficiencies in your home also mean there is less waste of valuable resources as reliance on natural resources is minimised.

Put your house to bed

At the end of the day, you’re not the only one who needs a break. Your home needs to unwind and unplug. Having unneeded appliances and electronics running constantly will drive your overall energy costs through the roof – save on this by simply unplugging and switching them off.

Seal All Windows

Go the extra mile by sealing the air leaks in and around the windows in your home. If your windows are drafty, consider adding weatherstripping around the frames. Add a bead of silicone caulk over any cracks in your drywall or apply a sheet of shrink film to your windows. Sealing gaps and cracks is an easy and inexpensive way to lower energy costs.

Replace Incandescent Bulbs

Halogen bulbs, compact fluorescent lamps (CFLs) and light-emitting diode (LED) bulbs offer longer lasting light and are more energy-efficient than your old incandescent bulbs. Since the average home uses 40 bulbs, switching over to greener bulbs is a great way to save on your electrical bill. Sure, the upfront cost is a bit more, but you will save more money in the long run because they last longer and use less energy.

Dimmers are also a great way reduce energy costs as you’re able to control the wattage that the lightbulbs use. great way to set the ambiance of a room. Another handy tip for having dimmers is that they can also extend the life of your lightbulbs.

5 signs of a poorly insulated home

Does your home have efficient insulation? If your home was insulated years ago and isn’t up to current standards, you may be noticing the signs of a poorly insulated home. It can result in uncomfortable and unhealthy living conditions and should be treated as soon a possible to reduce its harmful effects.

Here’s a few signs of poor insulation to look out for.

Have your energy bills increased over the years? This may be due to poor insulation within your home. If your insulation is old, it may have begun to settle – causing the insulation to be less effective, and making your home unprotected from cold and hot temperatures. This can result in high energy costs from needing to use the heater more often in winter and using air conditioning or fans in the summer.

Insulation provides homes with even temperatures throughout your home. So if you feel like different rooms have different temperatures – like feeling extremely cold in the kitchen, but then too warm in your bedroom – you’re in need of better insulation.

A good test on determining whether your home is insulated efficiently or not is to do the ‘touch test’. Feel your ceilings, walls and floors – they should be warm and dry – however, if they are cold or damp, it means your home doesn’t have enough insulation. The touch test also includes feeling your exterior walls – these walls should feel cold, as it means your insulation is doing its job of keeping warm air inside the home.

Feeling chilly drafts is common in homes with poor insulation. It’s caused by cool air entering through window frames and doorways. Spray foam insulation can be added to these areas to help prevent these cool drafts, to ensure your home feels much warmer in colder weather.

Noticing extra mould, moisture, or condensation around your home? This is generally a sign of bad insulation or ventilation in your home. Condensation is the process of damp air turning into liquid, making your home feel damp, and resulting in mould and moisture around your home. Keeping your home warm with quality insulation can help reduce the risk of mould and moisture.


If you’re noticing any of the 5 signs stated above, it’s important to act on it quickly to prevent any further damage to your home or health from poor insulation.
