Fastener-sealing eave protection is very helpful at the eaves and the valleys. If No.30 ASTM Type ll or No.30 ASTM Type lV roofing felt is installed on the remainder of the roof with a continuous ventilation product on top of the felt and eave protection you will have a great roof. If using a Certi-LastÂ® or shake felt system product you only need the felt and eave protection. What is the CSSB recommended procedure for base or sheathing protection? No. 30 ASTM D226 Type ll or ASTM D4869 Type lV roofing felt.

Venus takes 224.7 Earth days to complete one orbit around the Sun. So a year on Venus is 0.62 as long as an Earth year. One interesting fact about Venus is that a day on Venus is actually longer than a year on Venus.A Venusian day lasts 243 days, and a year is 224 days. That means that the day on Venus is 19 days longer than the year.Another interesting fact is that a Venus rotates backwards compared to the other planets in the Solar System. So on Venus, the Sun rises in the West, and sets in the East.o a year on Venus is 0.62 as long as an Earth year. One interesting fact about Venus is that a day on Venus is actually longer than a year on Venus. A Venusian day lasts 243 days, and a year is 224 days.
