As already explained in details about HD100 joint filler board here but one has an obvious question about what is the major differences between the modern polymers based joint filler board and the bitumen impregnated filler board. We have covered major points which are visibly understandable by normal users. Kampun provide both types of joint filler boards but it is the customers’ call to choose from.
We supply bitumen impregnated boards normally in the projects where it is rare possibilities to change the specifications in the last moments. As expected customers started moving towards the polymers based filler boards to meet technical as well as commercial gains.
