Make Your Home Winter Ready : 3 Best Ways to Winterize Your Home in New Zealand

Winter is just around the corner. This is the best time to get your home ready for winter with the temperature going down. Because even if you live in an area in New Zealand where there isn’t much snow, it’s important to make your home more weather-proof. The cool weather can do a lot of damage to your home, and your energy costs are likely to go up if you aren’t ready.

So, is your home prepared for winters?

Make sure your home has good insulation to keep you warm and save you money. It can also keep your home safe and last longer. It can even help keep your loved ones safe from animals that want to stay warm in the cold.

Here are the top key areas you must insulate in your home before winter.

Insulate Your Windows

No doubt,  windows are a big source of heat loss in your home. According to Energy.gov website “windows are responsible for 25%–30% of residential heating and cooling energy use”. . Two-thirds of the energy that is lost comes from heat that is radiated through windows. The rest comes from conduction through the frame and air leaks around the window.

So, what is the solution? Well, the first thing to do is put up curtains or blinds. This will prevent most of the heat from being lost through radiation.

Next, look around the frame for holes. It’s possible to seal these with affordable, self-adhesive foam strips, but they may not last very long. Metal or plastic strips that come with brushes are more expensive, but they are more effective. Also, you can use a thermal sealant to fill in any gaps in the walls.

Door and window insulation will help keep your home warm in winter, more comfortable, and reduce the load on electrical appliances such as air conditioners/heat pumps.


Insulate Your Ceiling

Some areas in New Zealand have excess rain and cold winters, and to stay warm, you need to live in a home that can withstand the cold, the wind, the rain and the snow. It’s one of the best things you can do for your home, but there are some areas that you should pay more attention to.

One of the best things you can do for your home’s energy efficiency is to insulate your ceiling. The money you spend now will pay off for years to come in lower energy bills and a more comfortable home.

An effective insulation system is required to keep the home warm and healthy and maintain the efficiency of heat pumps in winters. The selection of suitable insulating material is critical. It is an investment that pays you back every day with significant energy savings. It’s tough to increase your insulation afterwards without incurring additional costs.

Keep in mind that you must maintain a proper insulating system. Without the required components installed, a malfunctioning system might lead to moisture or water intrusion. Some moisture-absorbing insulating materials might lose up to 50% of their thermal efficiency.

Insulate Your Internal Walls

Likely, your exterior walls have already been insulated, but there’s no way to know for sure that the insulation is good enough. The most important part of wall insulation is making sure there are no gaps. For example, it can be hard to keep layers of batted insulation together because there are pipes, electrical outlets, and windows to work around. As a result, there may be gaps in your wall that need to be sealed and insulated.

Insulating interior walls help keep noise from travelling through your home. When you put insulation in your house, you can cut down on the noise from TVs, washing machines, and other things that make it hard to have a peaceful home.

Interior wall insulation can also help you save money on your energy bills. Insulated walls will keep the heat in and keep the warmth from going out in the winter. It takes a lot of energy for heating or cooling in the average home, so you want to make sure that it’s as efficient as possible.

Moreover, high-quality foam insulation permeability allows moisture to get out of the walls and into the air. In the basement, moisture trapped in the walls can lead to rot, mould and mildew. This is why it is important to have better moisture control in your home, especially in the basement in winters.


Insulation can help you solve both problems – cold house and high energy bills. When you improve your insulation and air seal it properly, you can enjoy a number of benefits, including reduced reliance on heating equipment, lower heating costs, improved air quality in the home, less maintenance on heat pumps, and stable and steady home comfort.
