What are the advantages and disadvantages of crital doors versus alumi

Looking to change our bifolding doors to crital doors but trying to understand what are the pluses/minuses with the crital solution. Aesthetically they are gorgeous. Just want to make sure we are not giving up on other things. Thank you!

    Hi Irini

    As a Crittall owner myself (although it's original 1930 single glazed) I am a huge fan!

    However, there are lots of pros and cons to consider - and presuming that you will be looking at double glazed?

    Crittall is generally more expensive, but has very slimline frames. The downside of this is that the thermal value of Crittall tends not to be as high as aluminium. The slim frames makes locking and ironmongery a bit more difficult, so it relies on standard locks and slider bolts for security. The door base detail is not very robust - and can allow water ingress unless you have a good external threshold drain. There is a steel window system called Secco which has a thermal break on the steel frame which can help.

    Aluminium tends to have much thicker frames, but these are thermally broken, and adds to the overall improved thermal qualities of the windows and doors. Sourcing stockists is easier, and you can also get treble glazed units. Also, the range of formats (ie bi-fold, sliding etc) is much greater.

    Hope that helps a little :)
