New uPVC windows transform Swindon home’s energy efficiency

Earlier this year, Emerald Windows and Doors installed new uPVC casement windows and a composite front door for Mrs Johnson at her Swindon home. The reported impact that the new windows and door has had on the property has been outstanding and is a perfect testament to the superior thermal efficiency of Emerald’s products.

Price comparison between local double-glazing installers

Mrs Johnson initially contacted us as she had visited our website and read our reviews, both of which she was impressed with. To begin with, Mrs Johnson requested we provide a price based on another company’s quote, rather than through a home appointment, as whilst her decision would not be solely price driven, she had set a budget and did not want to waste either parties time if this could not be met.

We were happy to accommodate the request and were delighted we could beat the competitor’s quote (which transpired to have been by thousands of pounds). As part of her decision-making process, Mrs Johnson took advantage of visiting our Swindon Showroom, to view and compare the frame, colour, glazing and furniture options. With the help from our sales representative Marc, Mrs Johnson decided on white double glazed uPVC casement windows, and an anthracite grey composite front door.

A glowing review following installation

Following the installation, Mrs Johnson was ecstatic with all the work carried out by the team and took to Google to share her experience:

‘Fantastic experience from start to finish. I know I wasn’t the easiest customer when ordering (I kept changing my mind), but Marc was fantastic and couldn’t have been more helpful. But special thanks needs to go to the installation team, Dion and Alex. Dion is honestly amazing. The pride in his work and the fine attention to detail he gives is outstanding. Nothing was too much trouble, and even when faced with challenges, he faced them with positivity and without skipping any corners. He is an enormous asset to the team and should be valued tremendously. 5-star x 10! Alex was also an absolute dream to have around. Warm, friendly, and endlessly helpful. He’d only been with Emerald for a week or 2 when he worked on our job, but oh my, you could just tell how capable and positive he was and what an asset he will also become. I really do think I had the ‘dream team’ here, so thank you so much guys.

I should quickly add it’s been a few weeks since our install now and everything is perfect. The quality of the windows and doors is great and looks stunning. And the difference in the outside noise heard inside is seriously amazing. In that you can’t hear a thing!

Thank you so much again. I would have absolutely no hesitation whatsoever in recommending Emerald Windows. Exceptional! (and several thousand £ cheaper than their competitors! win win!)’

Thermal images showcase transformation with new windows

Some months later, Mrs Johnson contacted us to report on the significant impact the new windows were having on her home:

‘They’ve made such a difference and never has it been more obvious than last night when it was rather cold. Previously, we would have really felt it, but the new windows have completely blocked it all out and kept the warmth in. Anyway, the reason I’m telling you all this is because I thought you might be interested that last year, in an attempt to see where the cold spots in our house were, we took some thermal images. And last night we decided to take some comparison thermal images. The differences are staggering and so thought you might be interested to see….

As you can see on the left picture, our old windows had some really bad cold spots. Not anymore!

We are so pleased and thought these pictures were worth sharing with you.’

Why choose uPVC casement windows?

As is evident from this particular case study, our upvc casement windows offer unbeatable energy efficiency. Achieving u-values as low as 0.9, the unique design of the system also ensures unrivalled wind resistance, water tightness and air permeability. The argon gas between the two panes of glass acts as a fantastic thermal barrier as it reduces the amount of heat escaping, keeping your home at a comfortable temperature, and reducing heating bills.

As well as this, our upvc casement windows have several benefits, such as high security and minimal maintenance. Read more on how upvc windows can transform your home here.
