Which uPVC Double Glazed Windows Are the Best for Me?

We all want the best for our homes. But if we’re thinking about upgrading our windows, what exactly are the “best” double glazed windows for our home, and why? The best of anything will most likely depend heavily on your own personal needs, wants, expectations and inevitably your budget.
One of the most popular reasons to invest in new windows is improved energy efficiency. Replacing old, draughty and rotten windows with new, energy efficient windows can make a huge difference to your home. They look better, cleaner, more up to date, and if you want to, it’s a great way to completely “reinvent” and modernise (or even re-traditionalise!) the entire look of your home.

Fensa Homeowner: The best double glazed windows combine your preferred style with high-performance features that improve your home, without compromising on either aspect. Top benefits include improved security and energy efficiency, reduced maintenance, less condensation issues and impressive sound insulation. Discuss what you want from your new windows with your installer, to ensure your investment offers the levels you need and if these are the best choice for you.

There are many different types of uPVC window, so how do you go about choosing the right type of window for you, your home and your budget?

Window styles and different types of window.

A top consideration for most homeowners is what style of window they are looking for. Keep to the same look, or go for something different? If you’re looking to replace the original windows in your home, in most instances we would advise you to stay as close as possible to the existing aesthetics, as these tend to work better with the style of your home.
If you’re embarking on a major refurbishment project, this is a great opportunity to give your home a fresh new modern look.
However in some cases, particularly with Victorian and Edwardian homes, a previous window replacement may have resulted in the traditional window being lost to a modern casement that looks completely out of place. Reinstating new modern energy efficient sash windows or traditional style casements will make a significant improvement to your home’s visual aesthetics.

I have used this company on several occasions for my own property with great results. This time, they fitted a new front door for my sister and were helpful, efficient and professional throughout, ensuring that the locking mechanism worked easily.
Their post-sales customer services is also excellent. Many thanks.

I’m so glad I found Ruislip Windows and would recommend them to anyone. Honest company, great workmanship, and exceptional aftercare. Any small issues were fixed immediately with no questions asked (they replaced a scratched internal pane and buffed a mark on the frame straight away). Friendly, helpful, and reliable in a market where trust matters. Couldn’t recommend them more.

I am delighted with the installation of the new double glazed bay windows in my home. The windows are very smart and the team who did the installation were excellent. The price was good (in the middle of 3 quotes I had) and the work carried out neatly and cleanly. I have the minimum of touching up to do in one room. I am very pleased and would heartily recommend Ruislip Windows & Doorsl

Our windows were fitted by Ross and his colleague. Both were professional and friendly and completed the job in the time given. The job was completed to a very high standard. The windows look great. Everything was left really clean and tidy, they even put our blinds back up for us. The process before hand - getting a quote and getting booked in was easy and quick. Overall really impressed with the service and wouldn’t hesitate to recommend to others. Thank you!

I have not had a chance to visit the property however my tenants are impressed by low sound levels and warmth. I asked the tenants to send me the photos of the new windows are installed. I am very happy with the service we received when me and my daughter visited their showroom/offices in watford. The service was excellent from start to finish. I will definitely use the company again and will recommend to my friends and family.

We contacted Ruislip Windows about replacing our porch and was pleased to find they could fit new front, side panels and trim and use the original roof and frame. The whole process from Mark visiting to discuss what needed doing to Rob and Ryan fitting the new parts was excellent, all old parts were removed same day and everything was kept clean and tidy. Rob's eye for the finishing details was second to none.
We have used Ruislip Windows before and would recommend them to anyone that asked.
Thank you to everyone we spoke to, we are well pleased with the final item.

The surveyor was very helpful when he came to measure up and advised us on the types of installations available and when we could expect the installation of our doors and windows.
We received a text, within the period advised by the surveyor, asking us when would be a convenient time for the installation.
On the day of the installation the first fitter arrived early in the morning and started removing the old windows and doors. Soon after a second van arrived with the replacement doors and windows and installation commenced. The men worked non stop and completed mid-afternoon. The surrounds of doors and windows were repaired where necessary. The old fittings were removed and all the rubbish swept up and cleared away.
We were shown how the locks and the internal blinds worked.
Overall we are very satisfied with the new doors and windows and the workmanship of the fitters. We would certainly recommend Ruislip Windows and Doors Ltd to anyone.
