ROOFING FELT, CO2 IMPACT MODEL

Embodied CO2 per unit of roofing felt is
3800kg of CO2 per tonne of readily made rofing felt.

Mathmatical model for udnerstanding how much timber that is needed for keeping the entire house at a neutral to negative netbalance of CO2 when using Roofing felt in the house:

Standard values for CO2 :
1,8 t of CO2 = 1 t of wood, which = 510 kg of pure Carbon (C)
1,8 / 0,51 = ratio value 3,529411… = 3,53

Weight of Roofing Felt, otherwise known as Tar Paper is Xkg/covering m2
this thus costs X kilogrammes of CO2.

Ne knowledge, roofing felt must achieve a standard of YAP 2200 or more for permanent housing. YAP stands for what cloth that is inside of the felt itself.
