In a world where sustainability is becoming increasingly important, improving the insulation of your home is one of the best ways to save energy while enhancing your living comfort. Well-insulated homes stay cool in the summer and warm in the winter, without the need for skyrocketing heating or air conditioning costs. Additionally, you contribute to reducing your carbon footprint, which aligns with the growing demand for eco-friendly solutions.
But where do you start? In this article, we’ll discuss simple and practical tips to improve your home’s insulation. Whether you're a DIY enthusiast or prefer to hire a professional, there are plenty of options to make your home more energy-efficient.
1. Start with the basics: roof insulation
Did you know that a large portion of the heat in your home is lost through the roof? This is because heat naturally rises, and if your roof is poorly insulated, it easily escapes outside. Therefore, roof insulation is one of the most effective ways to prevent energy loss.
There are several materials you can use for roof insulation, such as fiberglass, mineral wool, and insulation boards. The choice depends on your budget and the type of roof you have. Insulation can be applied to both the interior and exterior of the roof. If you’re looking for the simplest solution, interior roof insulation is less invasive than exterior insulation.
2. Floor insulation: keep the cold out
While you may not immediately think of it, poor floor insulation can also lead to significant heat loss, especially in older homes with crawl spaces. If your floor isn’t well insulated, cold can seep into your home from the ground, resulting in higher heating costs and cold feet in the winter.
Fortunately, there are various ways to insulate your floor. If you have a crawl space, you can apply insulation material to the underside of the floor. If you don’t have a crawl space, you can use insulating subfloors or special carpets. Adding floor insulation can significantly lower energy costs while improving comfort.
3. Improve wall insulation
In many homes, especially older ones, the wall insulation is not optimal. Poorly insulated walls can easily let heat escape, resulting in high energy bills. There are three types of wall structures to consider: cavity walls, solid walls, and timber-framed walls.
Cavity wall insulation is a popular and relatively easy way to improve your wall insulation. This involves injecting insulation material into the empty space (cavity) between the inner and outer walls. This is a quick procedure and often offers good value for money.
Internal wall insulation can be applied to solid walls by adding an extra insulating layer to the inside of the wall. While this takes up a bit of living space, it’s a good option if cavity wall insulation isn’t possible.
External wall insulation is another option if you want to improve the appearance of your home or if internal insulation isn’t feasible. Here, insulation material is applied to the outside of the house and finished with a protective layer. Although it offers the best insulation value, it is a bigger investment.
4. Double or HR++ Glass: reduce heat loss

Windows are another source of heat loss, especially if you still have single-pane windows. By upgrading to double glazing or HR++ glass, you can significantly improve the insulation of your home. HR++ glass has a special coating and a gas filling between the glass layers, providing excellent insulation value.
Installing well-insulated windows not only keeps the heat inside during winter but also prevents excessive heat in the summer. Moreover, it reduces noise pollution from outside, which is an extra benefit if you live in a busy area.
5. Don’t forget small cracks and gaps
While major improvements like roof and floor insulation can greatly impact your energy consumption, don’t underestimate the smaller measures. Cracks and gaps around doors, windows, and pipes can silently let a lot of heat escape.
An easy solution is to use draught excluders. They are cheap, easy to install, and can prevent significant heat loss. Additionally, you can seal joints and cracks around windows and doors with caulk or foam. Don’t forget to equip the letterbox and keyholes with draught-proofing as well.
6. Insulate the attic floor: save on spaces
you don’t heat
If your attic is not used as a living space, it’s wise to insulate the attic floor instead of the roof. This is often cheaper and easier, and it prevents unnecessary heating of the attic. By keeping the heat below the attic, you increase the comfort in the rest of the house without wasting energy on unused spaces.
7. Radiator foil: A simple but effective solution
Radiator foil is a cheap and easy-to-install tool that prevents heat loss through the walls behind your radiators. This is especially effective for walls bordering outdoor spaces. The foil reflects the heat back into the room, so you need less heating to reach the same temperature.
8. Insulate the pipes
If your house has a central heating system, the pipes carrying hot water can lose a lot of heat if they are not well insulated. This happens mainly in unheated areas like the crawl space, attic, or basement. By applying special pipe insulation, you can minimize heat loss and ensure that hot water retains its warmth by the time it reaches the radiators.
9. Curtains and blinds
While not traditional insulation measures, curtains and blinds can help regulate the temperature in your home. In the summer, good blinds and thick curtains can prevent the sun from overheating the house, while in the winter, heavy, lined curtains help keep the heat in. It’s a simple and effective way to improve insulation without major renovations.
Improving insulation in your home
Improving your home's insulation enhances comfort and saves energy. Key steps include roof, floor, and wall insulation (cavity, internal, or external wall insulation). Double or HR++ glass reduces heat loss through windows. Small measures like draught excluders and caulking are effective for cracks and gaps. Radiator foil and pipe insulation help retain heat, while thick curtains and blinds regulate temperature.
Insulating attic floors is a smart choice for unheated spaces. These measures contribute to a more comfortable, energy-efficient, and eco-friendly home. Do you have any questions? Feel free to contact us!
