Most buildings evolve over time, with little modifications and alterations or complete changes in use. However, you need to be careful when you do certain things. One thing in particular to be aware of is the risk if you want to modify a fire door. Even changes that seem innocuous could actually cause serious problems. We want to have a closer look at this vital topic here. Then, if you need solutions like fire door inspections in Stokesley, you can trust us.
Complete units
The most important thing to keep in mind is fire doors are complete units. Every element works together to achieve the right level of performance. Testing verifies this and also ensures they obtain a relevant fire safety certificate.
Because they are complete units, changing even tiny elements could potentially invalidate the certification. In the worst cases it could completely ruin the fire resistance and ability to stop smoke from spreading. This could put everybody in the building at risk, so you need to be incredibly careful.
What can you do?
Notably, there are a few modifications that may be acceptable. It all depends on what the manufacturer’s guidelines allow. So, you should always check them first. If you need any help, you can rely on us to do fire door inspections in Stokesley and other areas.
One thing you may be able to do is trim the bottom of a door. It’s vital that doors close easily on their own. Therefore, it is important they don’t catch on carpets and stay open. If there isn’t enough of a gap at the bottom, you may be able to remove a millimetre or two. However, remember to check what the manufacturer allows; you don’t want to remove material and expose the core or make the gap under the door too big.
You need to be careful if you’re planning to attach anything to a fire door, including signage or push plates. In some cases it is fine do this, as long as you don’t screw deep into the core of the door. Generally it is better to use adhesive. Plus, make sure any additions are non-combustible.
Changing the hardware may seem like something you should be able to do. However, it must be like for like and approved to use on the specific type of fire door. So, always be careful if you’re looking to change handles, closers, and hinges. Ask us to do fire door inspections in Stokesley if you have any concerns.
Modifications you can’t do
There are some things you should never do with fire doors. Most importantly, never cut into them or drill holes. Plus, never remove intumescent seals. In a number of cases you can’t paint the doors either, particularly if it will cover the seals or certification labels.
The simple rule of thumb here is, if there isn’t documentation from the manufacturer saying you can do a modification, don’t do it. It’s always better to leave the door as is than risk making it ineffective if there is a fire.
