Does your home currently have old metal windows or old Crittall Windows that are in need of replacement?
Aluminium windows today can accurately replicate traditional windows used in art deco homes.
There are some excellent and very experienced companies specialising in steel window replacements, including Crittall themselves. However what do you do if the budget does not stretch to steel windows?
Aluminium windows will be cheaper but there are things to consider as not all systems will be ideal.
Using Aluminium to Replace Crittall Windows
If your budget can stretch to the extra cost, you can have new windows in steel too.
It is important to choose a system that will replicate as much as possible the original windows. Some of the later Crittall Windows such as the W20, W30 and W40 types also lend themselves well to being replaced in aluminium.
Can new aluminium windows be fitted to existing frames?
Yes. Whether you have timber, hardwood, oak or stone surrounds, the right aluminium window system can be fitted to your existing surrounds.
However you may need to consider the option of replacing these frames as well if they are no longer in good condition. It is often the case that the subframes the existing windows are fitted to appear in good condition but only when the old windows are removed can rotting timber frames be spotted. An experienced window surveyor should be able to advise you on the condition of your existing window surrounds.
The advantage of retaining the existing frames of course that that internal decoration and external render won’t be disturbed minimising the work involved.
Don’t forget that modern aluminium window replacement can also be direct fixed as well.
Are aluminium windows energy efficient and secure?
With front to back dimensions of over 50mm with most systems this means Crittall replacement windows in aluminium can accept 24mm or 28mm units that are available with excellent specifications and an A rating if required.
It is important to remember that with such slim frame, much of the improved Window Energy Rating will be down to a good glass specification.
Some systems also have a sloping glazing bead designed to replicate the original putty line of the old metal windows. This putty line look can also extend to the glazing bars.
These modern aluminium systems also allow multi point locking and secure window handles to be incorporated. Specialist suppliers will also be able to customise the windows with period handles and even projecting hinges typical of the original ones used.
You can even have peg stays, butt hinges or the more modern concealed friction stays.
What about the glass on old Crittall Windows?
The right window installer will also take care of the small details such as those found in the original glass. Ask the about the type of lead used in the leaded lights and ensure it is the antiqued lead that is used and that the lead is soldered.
If your original windows have external and internal glazing bars, ensure that these also replicate the putty lines of the old windows if possible.
Replacing the Curved Bays or “Sunshine Bays”.
A stunning “like for like” replacement including curved glass and bars.
In many Art Deco Homes you will find the bay windows featuring curved glass on the sides. These are also known as sunshine bays.
These curved windows are very typical of the period. In recent years many homeowners chose to replace these with flat windows angled by a modern bay pole but the effect is not quite the same.
If you want to replicate the curved glass and curved horizontal window frames this will be a much more specialist job requiring the services of experienced aluminium bending specialists and a specially made curved glass unit.
The cost will be much more than a straight window with flat glass however the effect of the finished window you will find well worth the extra price.
So what can you expect with new aluminium windows?
If you choose the right window installer and one that is experienced in replacing old steel windows with the right aluminium alternative you will benefit from:
- Modern Windows that replicate the originals
