A basic guide to sprinkler systems – for developers who need one after height rule changes

apartment building renderIf you’re involved with the development of flats in 2021, you will likely already know that you need to incorporate a sprinkler system within the build if it’s over 11m.The change was made last May as part of the Government’s reform on fire safety. It was previously 30m, so many smaller developers will now need to know more about sprinkler systems or find someone else with the expertise.

RAD Fire Sprinklers Ltd has been installing them for more than 15 years – and can advise on all you need to know if the changes affect your projects that were previously outside of the height rules.

Director Paul Hummerston, said: “The change has meant that we are now working with many smaller developers who weren’t previously affected or needed to know about or install sprinkler systems. With our background in both construction and sprinkler systems, we are able to advise on the most suitable system for their requirements and installation.
“It’s important for us to work with the other trades and design consultants to ensure that the working parts can be hidden and blend into the aesthetics of the room.”

There are two types of fire sprinkler systems – RAD fits both:

High Pressure Mist – perfect for retrospective installations

  • These systems use a mist rather than a spray to dampen down the fire.
  • Up to 80% less water is required compared with a sprinkler system.
  • No tank or water upgrade is usually required.
  • Installed quickly, with minimal disturbance to walls and ceilings.
  • Less water on activation means less of your property is water damaged.
  • Often the preferred option by developers and architects.

Sprinkler systems – the traditional system

  • A discreet option for where the requirements of mists cannot be met.
  • Usually suitable for larger installations such as high-rise development projects and care homes.
  • As with mists, the sprinkler heads are activated by heat not smoke.
  • The system often requires the storage of water nearby.
  • Can be designed to complement lighting design to maintain aesthetic appearance.

RAD works with both private homeowners who need the system to satisfy building regulations, developers and mechanical engineers who are required to provide a safe exit route, ensuring the best system is installed for the property, budget and purpose.

I have used RAD for a couple of projects and found them to be good to deal with. They did a pair of 3 storey open plan houses and seven three and four story town houses. The sprinklers were to improve fire safety, allow more flexible space and comply with building regulations. The sprinklers were far more cost effective than the mist type systems and look very discrete when installed.

It has been a pleasure to deal with RAD for installation of fire sprinklers at our site is Sevenoaks. They were fast, professional, working to time and quote, which made it easy to work with them.

My requirement was a bit unusual for RAD in that I wanted a mist system in one room of a rented house. I had no drawings or technical back up. RAD were very helpful and repositioned the unit after the initial installation. Luckily with the help of Sonny, the engineer it all worked out very well.

As somebody who feels that it should be a necessity for all properties to have fire sprinkler systems, I am a big fan of this company. I have used them numerous times to service my home system and they are very knowledgeable. I would highly recommend their service.

One look at Rad Fire Sprinkler's website will tell you that these guys know exactly what they are talking about when it comes to Fire Sprinklers and the legislation surrounding fire safety. A very trustworthy company.
