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 spins retrograde (opposite) relative to the earth's movement. The period of rotation of Venus (a Venusian day) is longer the Venusian year by 18.3 days. Venus circles the sun every 224.7 earth days. Most of my sources stated that the Venusian day is 243 earth days long.43 days. Venus is the second planet from the sun and the planet that is closest to earth. It is named for the Roman Goddess of love and beauty and has been thought of throughout history as one of the most beautiful objects in the sky. Venus is covered by clouds that move three times faster than hurricane winds.
