Common on-site problems and solutions
Single sided access - Walls
On construction sites there may be cases where an aperture for a fire seal that is to be installed is only accessible from one side. With many of the Protecta. products this scenario is already tested, certified and included in our handbook, but one issue is the Protecta FR Board system which requires the sealing of gaps from both sides of a wall after insertion.
However this is solvable by using an additional inner board with the coating facing towards the installer; it will result in the same fire seal as the certified solutions. Below are the detailed descriptions and this is especially useful with risers or shafts with gypsum boards on only one side.
Single sided access - Floors
The Protecta FR Board system requires the sealing of gaps from both sides of a floor after insertion (these solutions can be found in the installation instructions for Protecta FR Board).
However, with access to only one side, this is solvable by using an additional upper board with the coating facing towards the installer; it will result in the same fire seal as the certified solutions. Below are the detailed descriptions.

Restrictive fire seals and the pattress solution
Some fire seals in walls can be restrictive, so it is difficult to insert the different pieces of the Protecta FR Board. Therefore Polyseam has tested a pattress system, where the boards are installed on the surface of the wall instead of inside the aperture.
This is then an additional way of fixing the boards, but the fire classifications will still be limited to the different services given in our handbook, for drywalls with the system 2 x 50mm 1-S. Furthermore, any FR Pipe Wraps must be included.
There are two ways the pattress system can be installed, as follows:
Solutions to problems do not have to be complicated, expensive and time-consuming, instead Protecta offers simple solutions designed and tested in apertures and services as installed in real situations and solved through complicated chemistry.
