uPVC Folding Doors

Bifold doors: Multiple sliding panels

Considered a luxury product by many homeowners, bifold doors feature a unique opening style that sees their panels fold up neatly to one side to allow for maximum views and generous space. uPVC bifold doors from Emerald slide smoothly across a track to create a seamless merge between property and garden.

Thanks to slim sightlines, effortless operation, and a versatile range of opening configurations, bifolds are the patio doors of choice for those who desire a great deal of customisability. Ranging from 3 to 7 panel arrangements, we can install bifolding doors to fit any aperture. Numerous panels make it easier than ever before to flood your rooms with natural light, instantly making for a lighter atmosphere and mood. You’ll never fail to enjoy the full beauty that the outside has to offer, all without having to leave the comfort of your home.

New Wave Doors: Versatile sliding action

Offering all of the advantages of bifold doors but this time allowing the panels to separate, new wave doors from Emerald offer homeowners complete control over their desired opening. Able to incorporate however many panels you require, new wave doors offer just as much natural light as bifolds.

With Emerald’s new wave doors you never have to compromise on living space because you don’t have to worry about bumping furniture in or outside the home when operating. To top it off, homeowners will never be restricted to having their doors either fully open or fully closed, only having to open the amount of desired panels to reach the optimal amount of ventilation and light.

  • We worried about choosing a window company. We looked at all the usual national firms but we preferred the feel of a smaller local family run business as the rep was understanding of all our needs. The main issue for us was a quick turnaround and high quality frames with high security. We got this and more from Emerald.

    We are really impressed with the smooth finish. The fitters used dust sheets and cleaned up at every stage. We have already recommended them to our neighbours. Thank you for good value for money and a great finish.

  • The sales team at Emerald Windows are extremely knowledgeable. My house is a period property so the look was a very big player in which company I chose. I put my trust in Emerald and it paid off as the windows look fantastic and have brought even more character to the house. All the neighbours praised the work.

    The team of fitters worked to a high standard, they also cleaned up as they worked. The house inside and out was tidier when they had finished than before they arrived.

    I couldn’t give Emerald a higher recommendation.

  • My husband and I recently had all of our windows and doors replaced by the Emerald team. Right from the start it was a friendly service that all came with a good overall price when compared with other companies.

    We decided to have the grey coloured exterior and white interior windows. We are very pleased with the quality of the frames. They are so complimentary to our home.

    All the fitters were very friendly and professional and performed a high quality installation. The overall experience was a good one, we would highly recommend.

  • Very happy with our replacement double glazed windows. The installation was very efficient, and the fitters worked very well together and they removed all the old frames and rubbish from around the house. It has all been installed in a very effective manner. I would definitely use Emerald Windows again.

  • We had three windows fitted from Emerald Windows, I love the way we were treated by all the staff in all departments – we had a very friendly service throughout the process. We were very happy with the high quality windows that were installed into our home. Overall fantastic!
