5 Easy Ways How to Insulate Your House For Winter

Hello friends, winter has arrived. And wondering how to insulate your home for winter, then it’s time to prepare your home for the winter season.

Friends, if you want to avoid cold in winter, then it is important for you to insulate your house. Insulating your home improves occupant comfort and saves money.

How to insulate your house for winter

It’s not always necessary to do a major job of insulating a home. We have told you the easiest and cheapest ways to insulate your house for winter.

Why insulate your house?

A well-insulated house is essential in winter, as in summer. In winter, a poorly insulated house lets the cold inside, thus increasing heating bills. In summer, insulating your house helps protect it from high temperatures, especially during heatwaves.

To maintain a pleasant temperature

Insulating your house helps maintain a stable temperature in the house. Insulation protects the house from cold and low temperatures in winter.

When it is poorly insulated, cold air infiltrates inside through areas of heat loss. They can be located at the roof, windows, walls, floor or even the chimney… Losses can be identified and measured with a thermal camera. Typically, you feel cold air when you are near these areas.

To reduce noise

Insulating your home is also useful for reducing noise pollution. Noises coming from outside, resulting from road, air or rail traffic, are sometimes very disturbing for some residents. When you live in a busy area or on a busy street, getting to sleep despite the noise can be complicated.

From one room to another, the inhabitants of a house can sometimes be disturbed by each other. Insulation limits exterior noise pollution, but can also improve the acoustics inside the house.

To save money

A well-insulated house consumes less energy and saves a lot of money. The more insulated a house is, the less there is a need to turn up the heating.

Heating represents one of the largest sources of expenditure in the budget of French households. The amount saved by insulation depends on several factors, such as the insulation product or the square footage of the house.

Some tips for insulating your house without work

To insulate your house in winter, it is not necessarily necessary to spend a lot of money and undertake major work. Discover some ideas to quickly protect yourself from the cold.

Protect your windows and doors

How to insulate your house for winter

To insulate your house, the first thing to do is to close the shutters when night falls. During the night, outside temperatures drop. Shutters help block cold air. Windows should also be caulked with thick curtains.

Installing thermal curtains is a good solution to maintain a pleasant temperature in the house. In front of the glass surfaces, the thermal curtain prevents temperature loss. Made up of a polyester lining and a multi-layer of wadding, the thermal curtain is ideal for combating cold walls. In terms of decoration, different colors are available to suit all tastes.

To prevent cold air from entering the house, it is also advisable to fill gaps around doors and windows. These areas are generally responsible for air leaks. It is possible to combat the passage of cold air with insulating tape and door sweeps.

In a house, not all rooms are heated to the same temperature. Closing the doors from one room to another is recommended so as not to lose heat in the main rooms.

Install reflective panels behind radiators

When the house is equipped with radiators, it is possible to retain heat in the rooms using reflector panels. Placed behind radiators, they reflect heat into the house. Rooms are warmed up more quickly and retain heat.

It is possible to buy insulating reflector panels in DIY stores. These insulating panels are simple to manufacture. Simply cover a cardboard board with aluminum. This tip allows you to gain a few degrees inside the house.

Install rugs

Carpets do not have the sole function of decorating the house. Although they allow you to add a personal touch to your decoration, they can be used to insulate the house.

Install rugs

Rugs insulate floors from cold drafts. Thermal bridges can sometimes be present between two floors. Certain types of floors, such as wooden floors, are susceptible to air leakage. Mats appear to be a good alternative for blocking cold air without filling the empty spaces between the slats.

Check the insulation of the house

If these tips are not enough to prevent cold air from circulating in the house, the insulation system is probably defective. It is then necessary to check several elements to find areas of heat loss.

The roof

The roof accounts for around a third of heat loss. Bad weather and normal wear damage the roof. It is important to check its overall condition and observe whether there are any missing tiles and whether moss has taken hold.

Cold air often passes through the attic. Checking that cold air is not infiltrating through the attic, whether convertible or not, is recommended. The insulating product may also have been damaged by rodents.

The Windows

Temperature losses can be caused by windows in poor condition. Depending on the region, double or triple glazing must be installed to insulate your house.

If the windows are already lined or tripled and the air is able to infiltrate, the window caulking may be dried out. If this is the case, simply change the seals to gain comfort.

The walls

Poorly insulated walls are easily identifiable. By running your hand over the walls, you can see whether they are insulated or not. If they are cold, it is likely that the insulation in the walls is insufficient or that air leaks are occurring.

If the cold is distributed over all the walls facing the outside, the insulation of the walls must undoubtedly be evaluated.

The roof, the keystone of your insulation

The roof is the element to prioritize when you want to keep the heat inside your house. In fact, poor insulation can cause a 30% increase in your energy bill compared to an unrenovated home.

This is why it is recommended to carry out thermal insulation from the outside. In addition to the roofing elements and insulation, it is recommended to install an under-roof screen.

It will help limit water and dust infiltration into the attic and preserve the technical characteristics of the insulation. Skytech Pro XL, aluminum siding reinforced with glass fabric, is designed to reinforce the insulation of your home.

HPV-certified (high water vapor permeability), it lets moisture out while preventing water from entering from the outside. It is easy to install thanks to a folding adhesive strip.

How can I make my house cold-proof?

To make your home cold-proof, it is important to take steps to prevent cold air from entering and warm air from exiting. Here are some tips to reduce the cold in your home in the winter:

Insulate your home

Check that your home is properly insulated. Insulating the attic and roof, as well as the walls, is essential to reducing the cold in your home in the winter. To ensure you spend a warm winter at home, here are the 3 points to check:

Insulation of the attic and roof is quite simple because, in a house, the roof represents no less than 30% of heat loss. With good insulation on the floor and on the walls of the attic, the heat will no longer have the opportunity to escape.

Fight against heat loss

Pay particular attention to heat loss at the level of openings—doors, windows, and bay windows. If you feel drafts around them, act quickly by making insulation joints with a product specially designed for caulking.

Another important source of heat loss in winter is the floor of the house. Hence the interest in placing a thermal protection layer between the floor and the covering, which will significantly improve insulation.

Keep the heat

Prevent cold air from infiltrating your home by installing a classic draft excluder inside or, even more effectively, a polyester double door sweep. You can also install thick curtains in front of windows and the front door to keep cold air out.


How do you insulate a house against the cold?

To insulate a house against cold, seal drafts, add insulation to walls, roof and floors. Use double-glazed windows and insulating doors. Install thermal curtains and use weatherstripping for movable joints. Proper insulation saves energy and provides a comfortable home environment.

What is the best insulation for a cold house?

For cold climates, the best insulation materials are Fiberglass Insulation, specifically Loose-fill Fiberglass Insulation with an R-Value of 60, and Blown-In Cellulose Insulation with an R-Value of 49 Spray Foam Insulation is also effective, offering a higher R-Value.

What is the most effective way to insulate a house?

The most effective way to insulate a house is to seal up air bypasses first, particularly in the attic. Careful installation increases the insulation’s R-value. If you’re building a new home, using insulated concrete forms is highly efficient. For existing homes, spray foam is a great option.
