The Benefits of Double-Glazed Windows, Doors and Conservatories

Double-glazing is a must if you want to keep your house warm and cosy and reduce outside noise. A layer of air trapped between two panes of glass acts as an insulator. This keeps heat in and noises out. Like all our products, they carry an ‘A’ energy rating that ensures a truly energy-efficient home.

But while the main benefits are minimised heat loss and energy efficiency, you can also look forward to reduced condensation build-up on windows and UV protection from the sun’s rays, which prevents your furniture and carpets from fading. Upgrading single panes of glass to double will give your home a new life. Along with helping to cancel out external noise, it’ll make your house more secure and increase the overall value and curb appeal of your property.

Wide Selection of Window Styles

Although we offer a wide range of home improvement services, our specialities have always been double glazing, windows and conservatories. We have a huge selection of quality windows in our range, with something to suit any home and any homeowner! Long-lasting, affordable and low maintenance, our uPVC windows are extremely popular.

They’re also available in hardwood, as is our range of doors. You can choose from a variety of different colours and glazing options and have them designed and custom-made to your liking. Whatever your tastes and whatever style of your home, you’re sure to find the perfect replacement windows for you. Take a look at our extensive range of window styles available from our Belfast location to see which one you like best. We’re proud to provide the best quality for competitive prices.

Double Glazed Doors

We also have various door styles to choose from, including French doors, patio doors, composite doors, front door and back doors and bifold doors. These are also available in both uPVC and hardwood. Replacement doors can be made to match your new windows for a consistent look across your home.

Patio and bi-fold doors are often installed for their large glass panes. Make sure the glazing is top-notch by choosing the highest quality products from Emerald Home Improvements. When you choose our double-glazed doors, you’re getting more than just aesthetically pleasing designs. Additional benefits include enhanced security features, reduced noise pollution, increased energy efficiency and more natural light in your home.


Conservatories are a great way to add value to your home and create a beautiful and functional living space. At Emerald, we offer a wide range of conservatory styles and designs that can be tailored to meet your specific needs and preferences. From traditional to modern, our conservatories are built with the highest quality materials and are designed to provide excellent thermal insulation and energy efficiency.

Heat retention is important and that’s why we always maintain high standards. Whether you want to maximise glass with a stunning orangery, build a conservatory with a flat roof or increase your space with a corner infill, we can help. Contact us today to learn more about our conservatory options and start transforming your house into the home you’ve always dreamed of!

How We Work

We start with a free design consultation, where we’ll visit your home and discuss your requirements and the options available to you. We take into account the age and style of your home, as well as your own personal tastes and offer sound advice. Following this, you’ll receive a tailored no-obligation quote that’s valid for 12 months.

There’s no pressure to make a decision right away. If you’re happy with what you see, all you need to do is let us know, and we’ll get your installation booked when it’s convenient for you! Our skilled window fitters will have the job done in no time. We manage the whole process so you have nothing to worry about.

Why Choose Emerald Home Improvements?

Why choose Emerald as opposed to one of the other double-glazing manufacturers in your area? There are actually a number of things that set us apart from other Belfast companies. We prioritise customer satisfaction above all else and our knowledgeable staff are trained to help you find the best design that fits both your home and your budget.

Knowing that your home’s security is paramount, all of our double-glazed windows come equipped with unique 14-point locking systems. Meanwhile, our doors feature maximum-security Ultion locking technology. We’ll help keep your home safe, and intruders out!

What’s more, all our hardwood and uPVC windows come with a 10-year insurance-backed guarantee for peace of mind. And they’re all made in the UK, using cutting-edge techniques and equipment. Our installers have many years of experience in fitting windows, doors and conservatories.

We’re FENSA accredited and members of the Plastics Window Federation and the Guild of Master Craftsmen. We also provide expert aftercare and support, so if you have any questions or concerns throughout the installation process and beyond, our professional team are on hand to help!
