Aluminium sash windows are still very popular for both traditional and modern properties. In many respects, sash windows can also provide benefits over the opening outwards casement window.

At Newlite, we offer the Alumatherm aluminium sash window. Alumatherm sash windows provide you with the benefits of slimline and durable aluminium with the classic features of a sliding sash window.

What are the benefits of an aluminium sash window?

aluminium sash windows in white. — A new build home with the latest aluminium sash windows by Newlite.

Sash windows enable bigger opening lights than traditional casement windows. The sash balances in sliding windows that slide the windows open and shut provide more strength than some hinges found on casement windows. Therefore if you are looking for big opening windows, it is worth considering whether sliding sash windows may be the better solution for your home.

There are many dwellings such as houses, flats and apartments constructed in the 1970’s fitted with old sliding windows. Many apartment blocks stipulate that any window replacements must be in keeping with the building as a whole. Our Alumatherm aluminium sash windows are an excellent replacement for these old silver sash windows. You will also find them more secure and more energy efficient.

What are the features of Aluminium Sliding Sash Windows?

At Newlite, we custom-design our aluminium sash window to meet the requirements of your property and your wishes. Choose a replacement window from Newlite, and you benefit from:

A secure and energy efficient window.
Choose from many different styles.
Over 150 RAL colours available.
Concealed sash balances for an improved appearance.
Available with period sash window features
Sliding sashes can tilt inwards for cleaning.
Authentic Astragal or Georgian bars available.

Can I have aluminium windows in a traditional property?

Yes. Our Alumatherm aluminium sash windows are available with all the features you expect to find in a traditional timber sliding sash window.

Examples include a retractable parting bead. This is the edge of the window that replicates the look of old box sash windows.

When viewed from the outside, you will also see the slimline detail reminiscent of the putty glazing used on old sash windows. The same chamfer and sight line is possible.

We even offer our aluminium sash windows with the option of either a slim or deep bottom rail to the lower sash, just like you would see on a traditional window. Even sash horns are possible with aluminium sash windows.

Finally, you can add the finishing touches such as period hardware, Georgian or Astragal bars and a choice of colours.

Newlite made and fitted black aluminium framed windows and doors for a two storey extension built during the last 6 months.The quality and look of the windows is just what we hoped for and the team have been quick to respond to minor issues that I'm sure are typical soon after installation.

Great service from start to finish, Alan answered my initial query very quickly and came round with brochures, he discussed what we would like and explained the different door types, he was great at advising what door would suit my property. Alan kept in touch and let me know when the door was ready to be fitted. Our fitter did a great job, was very friendly and polite, once he had finished he explained what he had done and ensured we were happy with the finished product and checked that the lock worked properly. I would definitely recommend this company .

Excellent service from start to finish, 100% recommended, the windows look brilliant, they work well and condensation has been eliminated. The team worked fast, protected everything, were polite and cleared up after themselves. Alan who managed everything was great, helpful and communicated well. No issues whatsoever.

When we decided to replace our timber windows, we considered several options but only became convinced that we should proceed when we met and discussed our requirements with Alan from Newlite Home Improvements. For the first time we felt confident that the quality of the product, the fitting and the after sales care would meet our expectations. Considering the size of the project which included every window and door in our property, we remained completely relaxed in the belief that our confidence was well placed - and it was! We would most certainly recommend Newlite, their fitters and their products without reservation.

Thoroughly recommended on all levels . Alan Burden and his team are a very professional outfit and I am glad to have come across them.I needed to find a local company who I could trust to complete the last stage of a staggered window replacement, having been very dissapointed by the previous installer.It quickly became apparent to me that we were in very good hands indeed with Newlite. The whole process was very well managed by Alan and his team . Here is a company with a no nonsense approach combined with good values and an obvious care to the project in hand. Thank you for a job well done.

Newlite's second job for us - first smart metal double doors and side windows, now replacing old double glazing units with new good quality products. This is a thoroughly professional set up, beginning with advice on what works best for us in the price range, then a surveyors check over to see off any problems in advance, then a fitter arriving on time, polite, and clearly with years of experience. Its important for me to trust people, and I do not hesitate to recommend this firm.

Quick response to enquiry of replacement windows and assessment with advice on all or selected from Alan. I wasn't pressurised into replacing all the windows at all. Newlite was recommended to me by a neighbour and after a bad experience on checkatrade previously and 1 neighbour having constant problems with leaking in a conservatory from another company - i thought better to follow a recommendation from a neighbour who has used Newlite for over 15 years and been consistently happy ..with no leaks from a conservatory and had many windows - recently ordering a large replacement kitchen window .. and said Alan really cares about customers being happy and always follows up with calls to make sure all is ok. Mine were fitted exactly when promised..and I'm really happy and pleased that a local company has done such a great job..lots of contact..immediate answer to questions ..flexible with fitting arrangements around my schedule..friendly polite fitters who were tidy and careful of surroundings and my new carpets and who worked really hard. Fantastic job ..ahead of time..i have no doubt if i had any queries or problems they would be addressed..i just wish they could sort my other renovations out too! . I'm so pleased and satisfied that I've asked them to quote for a glazing job in berkshire for relatives. It is hard to find honest traders these days and with such a lot of money at stake you need to know you will get what you are paying for and expecting. I wouldnt hesitate to recommend Alan, and the fitters Dave and Tony..a great team with an honest business who actually care about customer satisfaction in a decent and traditional way. Im so glad my neighbour gave me the recommendation.

We are so pleased with our new crittal windows and doors. Absolute top quality and the service we have received has been second to none from start to finish. Both Alan and his surveyor Adrien have been responsive to any questions along the way which has taken out a lot of the stress of our building project which might have otherwise been there. We are so pleased that we decided to go with this company. 100% recommend.

We got all our mid-century crittall windows replaced with aluminium ones by Newlite and Alan was amazing from beginning to end. He communicated with us consistently and was on hand for all our silly questions/alterations. The installers were extremely friendly and efficient and we were made to feel very at ease with the process. The finished windows are wonderful - the quality is clear! We love them, couldn’t recommend enough.

I am very impressed with Newlite Home Improvements and the professional service I received. Alan, the owner, was incredibly helpful throughout the entire process. I had a specific style of front door in mind, and Alan went above and beyond to source it for me. The service I received from start to finish was impeccable, and I cannot fault any aspect of the experience. I certainly would not hesitate to use Newlite again for other home improvement projects. I highly recommend this company to anyone seeking high-quality home improvement services.

Newlite is fantastic! We wanted some crittall style doors and a window for our extension and from the moment we got in touch with Newlite the whole process was easy. Alan talks us through the different product options and decisions every step of the way and always made it clear where we were at in the process, answering any questions we had. We were surprised how quickly the delivery was from measuring up and the installation was smooth and done to perfection. We absolutely love our new doors/window and would recommend Newlite to anyone!
