How much do windows cost? The price of windows is dependent on multiple factors, such as the shape, size, material (timber, PVC, aluminium), frame, glazing, opening mechanism (fixed, hinged, sliding), and hardware. Quality is also a vital factor, so if you’re getting new windows, go for quality, even if it means more money, because durable and airtight windows reduces heat. Windows cost between NGN50,000 and NGN80,000 depending on the materials used, or even more if they’re panoramic. Remember, don’t let the price be the sole factor. Before making the purchase, consult an architect or an experienced window supplier.

The correct choice of window is very important. Before replacing or purchasing new windows, we recommend you do some proper research into the different types available, their characteristics, and price. Pay attention to whether suppliers provide installation and maintenance services and whether they offer a warranty. Remember - windows are a long-term investment and should last for 10 to 30 years.
High-quality windows can reduce heat loss by up to 30%. The thickness and thermal conductivity of the frame plus the thermal conductivity of the glass determines the total impermeability of the window, i.e. the quality of the insulation that the window provides. Energy efficiency is most impacted by how well the windows are sealed - the best windows are those that are triple glazed. Installing quality windows can reduce heating costs by more than a third!
If your house or apartment is located in an urban area, near a major road or a railway line, without a doubt it’s vital that your windows provide good soundproofing. The effectiveness of the soundproofing is indicated by the Rw value.
Regular maintenance is certainly the key to long-lasting windows. However, what exactly this entails and how often differs from material to material. PVC windows are the easiest to look after - they just need wiping with a damp cloth from time to time. Aluminium windows can be treated in a similar way. Wooden windows are more demanding, especially those that are oiled since they require re-oiling every year. Varnished or painted wooden windows also need sanding down and re-finishing every few years, depending on how exposed they are to the elements.
There’s not just the practical side of things to consider. You should also think about the overall look of the windows - whether they’ll fit in with the aesthetics of your house or the rest of the apartment block. Fortunately, countless colours, shapes, and materials are available today, so it’s easy to find something that will look good.
Good quality windows that are properly looked after can last for over 30 years. Make sure your windows come with at least a 10-year warranty when you’re buying them.
Good quality window frames, locks, hinges, and glass are what prevent a window from being opened by force.
Buying new windows is of course a major investment, so we recommend you first ask around about possible suppliers and get quotes from several different firms.
One indicator of a top quality window is if it comes with a long warranty. A manufacturer or supplier who has confidence in the quality of their product will always offer a multi-year warranty. If used and maintained properly, the windows must remain in excellent condition for the lifetime of the warranty.
One of the most important factors for ensuring your windows last for as long as possible is to make sure they are installed properly and professionally. If not, so-called thermal bridges will soon occur, which will negate all the benefits gained by purchasing good quality windows. That’s why we suggest you go for a firm that has its own specialists for fitting and maintaining the windows when choosing a supplier.
When the windows have been fitted, the supplier should provide you with various documentation - certificates of quality and energy performance, and guarantees for the standard of work and product quality, as well as the windows’ technical specifications.
Among other things, the aesthetics and efficiency of your new windows depend on the material they are made of. Combinations of different materials, as well as the numerous colours, designs, and shapes available, mean that it’s possible to find windows that will fit the aesthetics of any building.
For wooden windows, perhaps more than for any others, the quality of the workmanship and materials is crucial (the timber must be cut at the right time and dried in the right way, etc.). Otherwise, the windows will not meet the required standards and will not do the job they are intended to do. We recommend high-quality windows made from laminated wood, protected using substances that do not affect the natural appearance or properties of the material. Not only do wooden windows look elegant and warm, turning any room into a comfortable place to spend time, they also provide excellent soundproofing and insulation. If they are regularly and properly maintained, they can last for decades, although in this respect they are more demanding than other materials. If the windows are made from poor quality timber, they will soon dry out and crack and become deformed and draughty as the elements take their toll. Certainly, there is always a risk of them being affected by damp, mould, termites and woodworm, and the list could go on. Wooden windows provide poor anti-fire protection, and of course, you cannot ignore the fact that they are about 30% more expensive than aluminium windows, for example.
There is a wide range of windows available to buy that are made from artificial materials and come at a very reasonable price. PVC windows are one example. They provide an adequate level of insulation and soundproofing, and are strong and stable in comparison to those made from other materials. They are weather-resistant, easy to maintain and very long-lasting. Unlike wooden windows, they offer better protection against fire as they don’t catch fire so easily and burn more slowly. As there are countless acrylic paints and wood-imitation designs on the market, it won’t be hard to find exactly what you are looking for. From an environmental point of view, PVC windows are partially acceptable as some parts can be recycled. However, some cannot because they are non-degradable and non-renewable. PVC windows respond to temperature fluctuations, so in summer they can become loose in the heat, while in rainy season they can be difficult to open and close unless they are well-protected. It’s also true that UV radiation affects the durability of PVC windows.
These windows are a great combination of a natural material and durability. The beauty of natural wood, which brings comfort and warmth to any space, combined with a protective aluminium cladding means you get the benefits from both materials. Windows made of wood and aluminium are characterized by excellent UV protection, impermeability, minimal maintenance (the occasional need to revarnish or repaint the internal, wooden side of the window), and durability. The external aluminium cladding comes in any of the colours from the RAL colour chart and there are also imitation wood designs. Both the aluminium and the wood are 100% recyclable. The only downside of these windows is actually their price - they cost 60% more than PVC windows.
Of all the materials used to make windows, aluminium is the toughest and most durable. Considered the best material, it is also the most expensive, but these windows are worth every penny as they remain in the same condition for years and years. They are very stable, offer good protection, and are easy to use and maintain. They are used primarily for glazing large surface areas. They can be finished in any colour, meaning they can fit in with the aesthetics of any home. Their only downsides are their price (they cost twice as much as PVC windows) and their somewhat weaker insulation properties.
When windows are fitted professionally and properly, it ensures their durability and energy efficiency. In this sense, the most important thing is that the seal between the wall and the window is tight. Any damage to the frame and the casement must also be avoided. There shouldn’t be any gaps when they are opened or closed and nor should they catch anywhere.
1) Windows are delivered on a specific day.
· 2) The fitters explain to you the stages in the installation process.
· 3) Walls, floors, and other exposed surfaces are covered to protect them from possible damage.
· 4) Existing windows are removed.
· 5) The angle, height, and depth at which the window will be placed is determined. The frames are dry-fitted in the window opening and it is checked that they are level.
· 6) The windows are placed in the opening and sealed depending on the selected installation technique (standard, eco-friendly, or RAL).
· 7) Finally, the work is checked one last time.
· 8) The fitters leave you instructions for the proper use and maintenance of the windows, as well as appropriate certificates and warranties.
This is the most common way of installing windows. The gap between the wall and the window is filled with expanding foam.
The gap between the wall and the window is filled with eco-friendly elastic foam that stretches and contracts according to the atmospheric conditions, thus ensuring excellent energy efficiency. This type of installation is especially recommended for older buildings.
RAL installation is mandatory when installing windows in low-energy and passive homes, but it is also recommended for any new building since it guarantees the highest level of insulation, with virtually no chance of any heat loss. On the inside, the windows are sealed with a vapour-permeable substance, and on the outside with flexible polyurethane (low-expansion) foam, which allows vapour to escape from the room, but prevents it from entering. RAL installation also prevents the penetration of water into the walls, and therefore stops the build-up of condensation.
