After installing the Noico 80 mil car sound deadening mat the next step was to install the heat and sound insulation. Noico makes three different thicknesses, 150 Red, 170 Green and 315 Red. Apparently the difference between the green and red is the strength of the glue but I haven’t confirmed this. I decided to use the 170 mil material for the floorboards and pedal box area and the thicker 315 mil insulation for the firewall behind my head. Remember this is in my Lotus Europa, a mid engine car.
Here you can see the two thicknesses. The thinner material is Noico 170 Green and the thicker Noico 315 Red.
Applying the material was quick and very easy, just peel off the backing and stick to the cleaned surface. A utility knife and scissors both cut the material easily. The Noico Red glue is pretty sticky stuff so once you press it down it won’t come off easily. The Noico Green does appear to be a little more forgiving.
I’ll be interested in driving the car and seeing what the noise levels are like but it certainly seems promising. The fibreglass panels used to sound like a drum. If I hit the firewall now you can barely hear anything. Carpeting should help even more, that comes next.
