Glazing fitted in 20 mins - measurements perfect. So easy, and the difference in warmth and noise levels is amazing. Will fit the finishers after Xmas. Really impressed- thank you 😊

I purchased 3 windows. The Clearview website is excellent, allowing instant quotes for different configurations. The videos and support material on the site are great. The communication through the ordering to delivery process was really good, and the windows were delivered to the advised schedule. The windows were great quality and were straightforward to install following the Clearview Instructions. I would certainly buy from them again.

Absolutely fabulous. Took a bit longer to arrive but it was worth it. SO easy to install, only took 30-45 minutes, and after doing the trim and sealing around the sides it’s made SUCH a difference to my bedroom, living in an end terrace on a traffic lighted junction in the city centre was so noisy at rush hour, but the traffic is a normal decibel now. Thanks so much - I’ll be ordering for 2 more of my windows in time. Your glazing has meant I will now not be thinking about moving anytime soon! Thanks!

Really did the trick providing a secondary barrier behind our sash windows against costal weather. We haven't had a winter yet but so far so good. We got the acoustic glass option and what an amazing difference its made to road noise too. I'll bet our thermal efficiency has massively improved too as there is no longer any draft. Great product so far
Also really good customer service! Thanks team :)

SLIMLINE SINGLE PANEL UNIT
Our front bedroom ground floor noise levels have gone from horrendous, distracting road noise to hardly a whisper after purchasing a secondary unit. The busy road is 3m away!
The company talked me through the measuring process and specifications for what was a complicated space to work with, with an unusual original frame and lack of space for fixing due to the sash windows taking up a lot of the frame depth.
The unit fitted perfectly and was exactly as expected in terms of weight and fixing. The noise reduction was better than I imagined. An added bonus is that it

Very impressed with Clearview.
The online ordering worked perfectly and the chance to double check before the ordere is put into production is a plus.
I ordered 8 units for the gound floor of my house including a very large unit for french doors.
All were manufactured to millimeter precision and delivered in 4 weeks, on the date specified, by a very helpful/friendly driver.
Extremely well packed, the overall quality of the frames and glass is first class.
All frames and panes are clearly marked to indicate their positions meaning installation took less than a day.
Ground floor complete and

A fantastic product. I phoned Clearview for technical advice before ordering and they couldn't have been more helpful. The online price calculator is simple to use and the installation instructions were clear and concise. The unit was well packaged and very easy to install. Looks smart, blends well with the existing window and reduces road noise.

I recently ordered a sash secondary window which I wanted to fit myself. A short time after I placed the order I received email confirmation of the order, but also with a drawing/specification of how the window would look, just to confirm sizes etc before they started making it. I was kept up to date throughout via email, and when the delivery date was set the window turned up on the arranged day, perfectly packaged with no issues whatsoever. Along with a totally realistic and fair price I would have no reservations in recommending them. Perfect service.

I was somewhat dubious about secondary glazing, but after several emails back and forth with Andrew, who gave us alot of prompt advice, we took the plunge and ordered the units to DIY. I finally got round to fitting it last weekend & we’re so pleased with it-it was very easy to install & looks great! Much better than we thought it would look! The units are very sturdy, but don detract from the window. It certainly helps block out noise - we just need the weather to cool down again now to see how effective it is for the warmth, but I'm sure they'll be good as they're so well fitting. All in all
