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, the hottest planet in the solar system. Venus is the second closest planet to the Sun. Telescopes reveal little about the planet due to global cloud cover. Venus' mass and volume are quite similar to Earth's (Venus' mass is 81.5% of Earth's and its volume is 86% of Earth's).Its almost circular orbital period is 224.7 Earth days.A 0.76 albedo makes Venus the brightest planet, earning it the nickname 'the Morning Star'.enus' mass and volume are quite similar to Earth's (Venus' mass is 81.5% of Earth's and its volume is 86% of Earth's).
