Types of Grey Windows

Deciding on the colour of your window frame isn’t easy, especially when you also have to consider the material that will be used.

Don’t worry, this guide will go over the advantages of each type and why they’re worth considering. This way, you can choose a window that will suit your current property, while catering to your interests and staying within your allotted budget.

Grey uPVC Windows

uPVC windows are extremely sought-after, and for a lot of good reasons too. Aside from being a good cost-effective alternative to other material options like timber and aluminium, this window type is also energy efficient and low maintenance.

They are easily customizable and come in various styles, shapes, and sizes. Features like Georgian bars or decorative glass are only some of the features that could be added to give your windows a more stylish look and feel.

Though it’s worth noting that grey uPVC window frames are more expensive than their white counterparts, they make up for it through their modern and sleek appearance.

On that note, how much do they cost exactly?

Window StyleSizeAverage Cost
Casement Window900mm x 1200mm£625
Tilt & Turn Window900mm x 1200mm£775
Sash Window900mm x 1200mm£815

Keep in mind that these are estimates. Compare these prices with Ecopreneurist to get the most updated market prices.

Grey Aluminium Windows

While aluminium windows are generally more expensive than uPVC windows, they are an investment for you and your home. This window material provides great insulation and will help you in achieving better energy savings.

Aside from their excellent durability, aluminium windows are eco-friendly since they are made with recyclable materials. Moreover, grey aluminium windows also have amazing versatility and can suit both contemporary and traditional properties alike.

While this window type is not the most expensive option in the market, it is also not the cheapest. Ecopreneurist can help you check the current market estimates of grey aluminium windows.

To give you a general idea, these are the price estimates for each window style:

Window StyleSizeAverage Cost
Casement Window900mm x 1200mm£925
Tilt & Turn Window900mm x 1200mm£1155
Sash Window900mm x 1200mm£1390

Grey Timber Windows

With proper maintenance, timber windows can last you for an entire lifetime! They also tend to last longer than windows made from uPVC materials.

This window frame material greatly benefits the environment since it is made from a sustainable source. They also provide excellent protection against excessive noise due to their natural qualities of being airtight and soundproof.

Grey timber windows are a great addition to your property if you prefer a classy and timeless design. They can also be easily repainted if ever you decide that you would want to try out a new style.

Note: they are the most expensive material option out of the three and usually cost around 50% more than uPVC windows.

For example, here are the average costs for each respective grey timber window style:

Window StyleSizeAverage Cost
Casement Window900mm x 1200mm£1700
Tilt & Turn Window900mm x 1200mm£1300
Sash Window900mm x 1200mm£3300

Now that you know about the different types of frame materials you can choose from, it’s time to show you some of the most recommended and commonly used shades of grey for window design.

Anthracite Grey (RAL 7016)

Did you know?

Anthracite is a compact form of coal that has the highest energy density of all types of coal.

It’s no wonder that its colour form is often described as a chalky and very dark tone of grey.

Arguably the most popular choice of both homeowners and designers alike, anthracite grey windows are versatile and can complement both light and dark-coloured renders.

Key Information

House rendering refers to the process of applying a protective and decorative layer to the exterior walls of the property. This process can certainly add to the house’s value and usually costs around £2,000 to £8,000.

This shade of grey is highly suitable for contemporary homes, due to its deep blue and purple hues that offer an edgy twist, as well as its submetallic lustre.

Slate Grey (RAL 7015)

Whether you have a classic or contemporary home, this might be the shade for you!

As one of the more versatile shades, slate grey can easily be paired with both bright and muted accent colours.

Slate grey windows are a shade lighter than anthracite grey so they often appear softer against traditional properties and are best paired with exteriors that have a white or light-coloured render.

It is a dark shade that has been mixed with a hint of azure for a cool-toned, modern look, as well as earthy undertones of red and brown that become more visible when paired with a warm, red brick exterior.

Agate Grey (RAL 7038)

Agate grey windows are a great and fresh alternative to other darker shades of grey currently in the market.

Also known as “Painswick,” agate grey is a lighter shade of grey with subtle hints of green that can add a touch of elegance to your home.

This shade of grey is best combined with neutral colours such as modern black or sophisticated cream. It is also popular among heritage property owners since it perfectly complements light or yellow-tinged stonework.

Light Grey (RAL 7035)

Best known for its warm and calming tones, light grey is an achromatic colour that is made by mixing a small portion of black with a white base.

Some would even consider it the perfect neutral colour since it can add depth while providing a light and airy feel to the overall aesthetic.

Light grey windows excellently complement modern houses, especially those with bright-coloured exteriors. They are also a less heavy alternative for contemporary designs.

So if you own a property with a modern design, this could be the shade for you.

Disadvantages of Grey Windows

While it might seem appealing to simply join the trend, you should ensure you’re well-informed before making a decision.

Not to worry because this guide will tell you all that you need to know about the downsides of installing grey windows.

Increased Cost

Grey windows are typically more expensive than the standard white ones, which may put you out of your target budget.

Depending on the material used, some window frames would also require repainting since the colour may start to fade or change completely. This is another added expense to consider before deciding on getting grey windows for your home.

You should check Ecopreneurist to ensure you get the most updated prices for grey windows.

Possible Fad

Yes, grey windows are trending right now. However, there’s no telling when they will go out of fashion.

If you’re a house flipper looking for ways to upsell your property, or simply a homeowner surfing the web for renovation ideas, you should consider that this trend could be just another fad in the making.

Dull Appearance

Grey-coloured windows can appear dull and washed out, due to their dark colouring. In certain situations, it could even resemble cement, which is not something you would want for your windows. This is especially true if the surrounding features do not complement your chosen shade of grey.

Benefits of Grey Windows

Grey windows may have their negative characteristics, but they also have redeeming qualities.

So don’t get too discouraged just yet, because this section will focus on the advantages of installing grey windows for your home.

Aesthetic Design

Question: Do you believe in the saying that your home is a reflection of yourself?

Whether you believe in it or not, everyone can agree that they would want their house to look as aesthetically pleasing as possible.

As a neutral colour, grey windows can easily blend in with most interior and exterior styles. It also provides more contrast to colourful designs and complements the changing seasons, as well as seasonal decorations.

Versatility

One benefit of this window colour is it can be incorporated into multiple styles, designs, and sizes.

As one of the more versatile colour options, grey windows can easily be integrated and stylized to fit your property’s current appearance, as well as your personal preferences.

Minimal Upkeep

Compared to their white and bright-coloured counterparts, grey windows are easier to maintain.

For example, dirt and blemishes are harder to spot on these windows, lessening the need for cleaning and keeping them looking their best at all times.

Are they worth getting?

Considering all of this essential information, the choice is yours whether you think grey-coloured windows are worth installing.

Though they have their disadvantages, grey windows provide many great benefits that are ideal for both contemporary and traditional houses as they create a timeless look.

Installing them will enhance your property’s appeal and aesthetic, while still complementing your current exterior. This can be done especially when you choose the right material and shade.

Remember to consider your personal taste and your home’s architectural style to create a cohesive look that is sure to impress.

Are grey windows energy-efficient?

The colour of the window frame does not directly impact energy efficiency. However, the material and glazing type of the window play crucial roles. Opting for energy-efficient materials and double or triple glazing can enhance the overall energy performance of grey windows.

Do grey windows require more maintenance?

The maintenance of grey windows depends on the material used. UPVC and aluminium windows often require minimal maintenance, while wooden frames may need more attention. Regular cleaning and occasional inspections are generally sufficient for maintaining grey windows.

Are grey windows suitable for all architectural styles?
