How can I upgrade existing doorsets?
There are numerous methods for upgrading existing doorsets to enhance their inherent fire resistance, although every upgrade is specific to each doorset and consequently may not necessarily be appropriate for another design. The only way to ensure that the most appropriate method is chosen - and to have the enhanced integrity performance underwritten - is by commissioning a site survey by a qualified fire engineer. The relatively large number of components that make up a fire-rated doorset are integral to its performance and a comprehensive knowledge of these components is needed, eg:
- Whether the door can be upgraded to the required integrity.
- What the most appropriate upgrading measures are.
- If there are other issues that may negate the performance of the door, such as sidelights or over panels.
- How to address glazing, panelling, ironmongery, intumescents, core type etc.
