Temperature Reduced On Metal Roof With Belzona



Buildings & Structures (BSTR)



Roof Problem Areas (RPA)


Customer Location:

Hospital, Teesside, UK


Application Date:



Application Situation:

Steel roof over Medical equipment store.



Leaks were evident from the jointing trims on the roof and the very narrow gutters. An additional problem during the summer months was the high internal temperatures of the rooms beneath and air-conditioning units would struggle to keep the areas cool enough for the staff and supplies. In fact, the building was known locally to staff as the “biscuit tin”, as you would bake inside it.



Belzona 3111 (Flexible Membrane)



Sectional steel roofing.


Application Method:

The application was carried out in accordance with Belzona Know-How System Leaflets RPA-1, RPA-6 and RPA-8.


Belzona Facts:

The Belzona 3111 water based membrane was able to seal the most complex of geometries with a simple brush application. Despite the gutters being only 70mm wide and having restricted access, they were all successfully sealed. The whole roof was protected with Belzona 3111 in a light grey colour to help with solar reflection in the summer, and so help reduce the temperatures inside.
