Products & Services

Natural Ventilation Systems

We supply a wide range of electric and manual options depending on what you are trying to achieve. Systems will range from simple manual systems for a conservatory for example, through to larger commercial buildings such as schools and hospitals which need more complicated ventilation strategies.


AOV System

A range of opening distances to suit the required free vent area for aov windows.

For stairwells and lobby windows

If you are looking for Automatic Opening Smoke Vent (AOV system) and smoke control systems, get in touch with our experienced team today and we can have automatic smoked vents (aov vent) installed for your protection. Here at Rocburn Limited, we’re passionate about making both domestic and commercial buildings as safe as possible, and we pride ourselves in fitting the best smoke ventilation systems around.

In commercial buildings and multi-occupancy buildings, there is a requirement by law to keep escape routes clear and free from smoke to enable both occupants to escape and to allow fire brigade access.

Our smoke ventilation systems are governed by standards such as BS EN12101 and Approved Document B, and they are discreet systems which do not impede access or exit routes.

To learn more about Smoke Ventilation & aov windows the steps we’ll take you through as part of your project please read our overview document below.


Electric Window Actuators

For us electric window openers, also known as electric actuators are more popular than manual systems, there are a range of products to suit various applications. For example, in schools and commercial applications the Topp ACK4 window opener is used regularly as it is robust window opener with an adjustable stroke and has brackets which can be used in most situations.


Manual Window Openers & Teleflex Window Openers

A manual system would be a natural ventilation system you would use by hand, this can either be operated by a remote handle, an opener pole or a cord and the best choice depends on your specific application.

Customer Testimonials

Brilliant product and after sales service,particular mention to Matt who help me immensely with a setup issue


Seriously professional guys with old fashioned attention to customer service!! Fantastic! Thank you so much for your help, it was greatly appreciated!!


Had a problem with my fire control panel (installation error, not manufacturing problem) and Adam at Rocburn supplied new equipment v. quickly and talked through the new installers to ensure everything ran smoothly. Can't fault their service. Thanks Adam.


So pleased with the advice and service I got from these guys when ordering & installing motors and programmer for two conservatory rooflights that I bought another (slightly different, on Rocburn's advice) kit for three Velux windows in our kitchen. Electrician came yesterday and fitted them saying these were an "even easier" install! Many thanks to Adam & Ben at Rocburn. A brilliant company with old style customer service!!!


Adam from Rocburn was incredible. I was in the middle of selling my house, building control wouldn't sign off unless we installed an AOV. I was in a huge hurry to get the work done before moving out and completing with little over a week to get it done. Adam at Rocburn went above and beyond to help me out. I ordered the AOV on the Friday, it was delivered by the Monday and Adam lined up an improved installer to come in and fit it by the Wednesday. They removed my old velux, resized the opening, fitted the AOV and made good ready for the plasterer. And I received my commissioning certificate the very next day! how about that for service. If I could give them 100 stars, I would. Their service and help, literally saved my house sale and also got me out of an immensely stressful and time pressured situation, I honestly cannot thank them enough.They were amazing!


Thank you James D for all your wonderful assistance this week. You couldn't have done more to help me diagnose and sort out two broken window openers in my conservatory roof and send new openers for delivery the next day. You're a star! Five stars actually!


I have nothing but praise for Adam at Rocburn Ltc. He was courteous, helpful and very patient. It is quite rare to get such excellent support and I would not hesitate in recommending him and Rocburn to anyone considering fitting a similar window opening system.
Thank you.


I can not think of another company that has given such outstanding service. I placed an order for an electric opener. Adam called to make sure I was happy with the order and took time to explain the workings etc. we decided that it would not work. he then sorted through a different approach and we had another chat and agreed that because of the type of window that would not work either. he was simply fantastic in working with what the customer - me - needed rather than go for a quick sale. if there were 10 gold stars to award it would not be enough. well done Adam.
