Sorting Arrays. PHP has several functions that deal with sorting arrays, and this document exists to help sort it all out. The main differences are: Some sort based on the array keys, whereas others by the values: $array['key'] = 'value';
Can I install Roof-TopÂ® EPDM membrane directly over an existing roof? You can install Roof-TopÂ® EPDM membrane over an existing roof only if a new layer of 5/8â plywood, 5/8â OSB board, or polyisocyanurate board with a fiberglass backing is used as a barrier to protect the EPDM.
We recommend the âfully adheredâ method of installation. Simply use Roof-TopÂ® bonding adhesive to adhere EPDM to the underlying surface. For easy step-by-step instructions on installing your EPDM rubber roofing, please review the installation instructions below and/or order our installation DVD. For additional information, please feel free to contact our knowledgeable and experienced sales staff at (866) 630-7660. 1  EPDM membrane.  Bonding adhesive.
