This approach will allow batt insulation and avoids plastic foam, but only works In the event the roof is a simple gable style, which frequently isn't the case. Hips, valleys, and dormers could make this sort of venting impossible. In addition, The skinny plastic baffles are so flimsy they normally get crushed when rafter bays are crammed with insulation.
Bulk insulation solutions (for click here example batts and rolls) have countless tiny air pockets in just their composition which split up the flow of heat. Batts and rolls are great when you need to reduce the conduction of heat move in between objects which can be adjacent to each other.
These semi-crystalline thermoplastics can work well in temperatures up to 450 °File; even so, they go through degradation instead of melting when exposed to higher temperatures.
