Topshield, a manufacturer of roofing and siding products, announced on Monday the launch of its CraftGrade Independence underlayment. The company said in an April 8 news release that it is designed to be “35-times stronger and eight times lighter than 30-pound felt.”
CraftGrade, Topshield’s premium product line, added that the underlayment’s construction ensures durable weather and tear resistance, and an anti-slip coating with skid-resistant properties helps prevent slips and falls.
