London Crystal Buildings Ltd

Mortlake House is situated on the Chiswick High Road in London W4. The building which was recently refurbished with a two-storey extension, providing an additional eight luxury apartments to the existing 5 storeys.

As part of the life-saving fire safety systems for high rise residential buildings, a suitable smoke ventilation system had to be installed. The requirements for smoke control in new and refurbished buildings are detailed here.

In this particular development, it was necessary to replace the existing windows on each of the floor corridors to those that are fully tested to the legislative compliance. Often developers are aware of the basic AOV requirements but believe, quite wrongly, that they simply need to install actuators to the existing (untested) windows. This is not the case, not only must the opening of the window/vent meet the aerodynamic free area required for that particular location, but also the window/vent and actuator need to be fully tested together.

Fortunately, with our strategic partnership with A-Plus windows (who, like Silver Group, are Certified Partners of SE Controls) as well as our own in-house smoke control specialist, Silver Group were ideally placed to assist the developer and provide the best solution ensuring their complete compliance to the necessary regulations. Having fully assessed the property, we were able to provide the replacement windows with actuators pre-fitted in the required window profile. Crucially this window and actuator combination have been rigorously tested by SE Controls to ensure they exceed the requirements of British standard EN 12101




I have always had a great experience with Silver Group, everyone from head office to the engineers, they are always very helpful.

Silver Group are available 24 hours a day and are always helpful, we cannot fault the service. The equipment is very easy to use but, if we do ever need any help, we know they are always there. We would recommend Silver Group to anyone.

Silver Group provide a professional, quick and efficient service. From the initial survey of the property to completion, all engineers and employees were polite, clean and informative. I would recommend that anyone looking for an AOV system speak to Silver Group.

Having used Silver Group for several years on many development projects, they have always been very thorough from design to install. Their advice has certainly saved us a few headaches!

Silver Group understood our needs and designed and installed a system that met those needs in an efficient and friendly manner, a job well done!
