How to improve your home's thermal insulation without major renovations

When the cold arrives, keeping the home warm and comfortable becomes a priority. However, many homes lose heat through poorly insulated windows, walls, ceilings and floors. This requires turning up the heating, which sends energy bills soaring. The good news? You don't need expensive renovations to improve thermal insulation. There are simple, affordable and effective solutions you can apply yourself that make a big difference to your home's comfort and your pocket.

Why is improving thermal insulation important?

As we have seen, up to 30% of heat in winter is lost through poorly insulated walls and ceilings, while another significant percentage escapes through windows and doors. This not only affects your comfort but also increases energy consumption and, therefore, your expenses. Good thermal insulation allows you to:

• Maintain a stable temperature at home.
• Reduce the use of heating and air conditioning.
• Save on electricity and gas bills.
• Contribute to sustainability by reducing CO₂ emissions.

Furthermore, improving insulation doesn't just protect against the cold; it also helps keep the house cool during the summer by preventing outside heat from creeping into your home.

Solutions to improve insulation without major renovations

There is no need to undertake major renovations to solve it. With small changes and easy-to-install materials, you can reduce heat loss, save on your bill and enjoy a more comfortable home this winter. Here are the most effective strategies to improve insulation without complications.

1. Reinforce window and door insulation

Windows are one of the main sources of heat loss. To reduce heat loss without changing the frames, you can:

• Install adhesive draught excluders on door and window seals. They are cheap, easy to fit and prevent draughts.
• Use transparent thermal insulating film on the glass. This material creates an additional layer that reduces temperature transfer.
• Hang thick thermal curtains. Besides being decorative, they act as a barrier against cold and heat.

2. Improve interior wall insulation

If you notice the walls are cold, you can take action without needing major works:

• Decorative insulating panels: easily installed and provide thermal comfort.
• Natural cork cladding: an eco-friendly and highly effective material.
• Thermal-backed wallpaper: ideal for adding an aesthetic touch while improving insulation.

3. Insulate the floor without lifting it

The floor can also be responsible for energy loss. Here you have some quick solutions:

• Thick rugs and thermal carpets: help retain heat in winter.
• Vinyl flooring with an insulating layer: easy to install and very practical.

4. Reinforce ceilings and lofts

Heat tends to escape upwards, so it is worth addressing ceilings and lofts:

• Extruded polystyrene panels installed on the interior.
• Special thermal paints for ceilings.
• Reflective insulation rolls in lofts.

5. Sealing cracks and gaps

Before applying any solution, it is important to check doors, windows and walls for leaks. Even simple silicone sealant can prevent draughts and improve thermal efficiency.

Additional benefits of thermal insulation

Improving thermal insulation doesn't just translate into financial savings; it also transforms your home into a more comfortable and efficient space. Good insulation implies the following:

• Keeps the temperature stable, preventing cold from entering in winter and heat from entering in summer.
• Reduces outside noise, creating a quieter and more pleasant environment.
• And let's not forget the positive impact on the planet: consuming less energy means reducing emissions and contributing to a more sustainable future.

Practical tips to maximise savings

To get the most out of these improvements, combine several solutions. For example, if you have timers or smart home systems, use them to adjust heating and appliances for the most efficient times.

In addition, there is a key point you shouldn't overlook: check your electricity and gas plan. Good insulation reduces consumption, although choosing the right plan is just as important for maximising savings. At Endesa, you have options designed to adapt to your lifestyle:

• Fixed price, for those seeking peace of mind and stability in their bill.
• Time-of-use discrimination, ideal if you can concentrate consumption in off-peak hours and take advantage of weekends.

Combining a well-insulated home with the right plan is the perfect formula to reduce your energy spend without sacrificing comfort.
