Are aluminium doors thermally efficient?

Modern aluminium doors from Ventrolla feature cutting-edge thermal break technology. Designed to notably reduce heat loss and condensation, unlike old steel and aluminium doors, our robust multi-chambered aluminium frames will not contract or expand in extreme temperatures either.

Incredibly thermally efficient and strong, depending on the glazing specified, our aluminium doors can achieve A+ energy ratings with non-insulated, super-insulated & Passive House compliant frames available.

Can you put aluminium doors in listed buildings?

It is always best to repair historic steel doors where possible. However, this is not always a viable option, especially if they have been neglected over the years by previous owners. If your renovation plans include altering heritage doors in listed buildings, conservation areas, or locations covered by an Article 4 Direction, consent may be required to go ahead.

Working closely with local conservation and planning officers, English Heritage, Historic England, Historic Scotland, and Cadw, if renovation is not a viable option, we can supply completely new aluminium doors designed to seamlessly replace original iron or steel doors.

How do I know when to replace my door?

There are certain signs to look out for, including:

  • Rusty, rotten, warped, or peeling frames
  • Draughts or leaks
  • Damaged or foggy glass
  • Sticking or difficulty opening and closing
  • Mould or mildew
  • Increased bills or noise from outside
  • Obsolete locking mechanisms
  • Single glazing

What our customers are saying

Ventrolla were able to beat all the other quotations that I received and answered queries quickly and informatively, making changes as required promptly and without fuss. I was kept informed throughout of lead times and manufacturing times. The real stars of the show were Rob and James who worked tirlessly and brilliantly as a team to repair sash boxes where required and install our new sashes. Thank you!


Everybody I dealt with has been super friendly, informative, and helpful. I received emails with updates on what was happening, etc. It has been a great experience from start to finish.


I used Ventrolla to renovate my sash windows over to years ago. When two of them finally collapsed, including a bay window the size of three full sized Georgian windows they were my first contact. The office staff, surveyors and the three fitters that did an amazing job installing them in less than two days were all excellent. The quality of workmanship and the standard of installation were first class, and the new windows look amazing. I will definitely be using them again as more of my windows will need replacing over the next few years.


This is the second property Ventrolla have restored my windows for me, and the this job was every bit as good as the first. 14 sash windows in a Grade II listed building installed/refurbed without a hitch in week. The team of 4 installers were lovely chaps, super efficient and tidy. All round another fabulous job done – thank you the Ventrolla Team
