Fireproof Insulation UK 

GRJ Contracting can offer a range of fireproof insulation products to protect both domestic and commercial buildings. Fire stop insulation materials use insulative and non-combustible properties to slow the spread of flame and smoke. Materials such as mineral wool, fibreglass and cellulose-based wool insulation are used to safeguard against the rapid spread of fire. This type of insulation material has been developed to resist heat and to gain time in an emergency. As well as this protection, the insulation is designed so that if it was to come into contact with flames, you can be assured that toxic smoke isn’t released into the air.  
Fire-resistant insulation can protect a building’s structure and offer valuable time for appropriate evacuations. From non-combustible insulation (used to retains energy efficiency) to fire-resistant boards that create a safe protective barrier to prevent the spread of fire, we have a number of other accessories to make your building fire-safe.

"Gone beyond what has been expected" 

GRJ has been a good subcontractor on this project. I will hopefully work with them again on my next project. I would say in instances they have gone beyond what has been expected to develop solutions to on-site design issues. I think it is important that this is recognised.
