Oct 7, 2020 · A built up roof system, also known as a BUR, consists of layers of asphalt and ply sheets that provide superior protection.

Flintglas® Ply 4 is a functional building block within CertainTeed's built-up roof systems. Built-up roofing or BUR derives its unparalleled strength by building up layers of ply sheets and hot asphalt.

GlasPly IV is intended for use as an interply in any built up roofing or modified bitumen roofing system. It has excellent porosity making it easy to handle and lay lines that allow the roofer to install the felt with the proper exposure and provide the correct number of plies.

Jan 11, 2024 · A built-up roof is a roof that has been treated with the application of specialized roofing materials to strengthen, seal, and finish low-slop roofs. A BUR consists of multiple layers of adhesive materials, alternating ply sheet fabrics, and surfacing materials and finishes.

TYPICAL 4-PLY BUR SYSTEM WITH GAFGLAS® STRATAVENT®, FLEXPLY™ 6, FLOOD COAT, AND GRAVEL Built-Up Roofing (BUR) systems are composed of alternating layers of asphalt and reinforcing fabrics that create a finished membrane. The reinforcing fabrics or ply sheets are applied by either hot-mop or cold-applied adhesive methods.

Versatile GAFGLAS® Ply 4 Sheet for Built-Up Roofing (BUR) offers maximum strength and stability and can be used in all climate zones as a base sheet, ply felt and more. Find details here!

Sep 26, 2024 · A built-up roof (BUR) is a type of roofing system that has been widely used for flat and low-slope roofs. Known for its durability and waterproofing properties, a built-up roof consists of multiple layers of materials that provide significant protection against the elements.

Ply IV (4) and Ply VI (6) felts offer excellent durability and ease of application when constructing Elevate Built-Up Roofing (BUR) Systems. BUR tends to be a preferred solution for low slope roofs, as it provides a continuous sealed surface to resist water penetration effectively.

A 4-Ply roofing system involves roofing felts that are typically four plies composed of layers of reinforcement such as fiberglass or polyester felts, with each ply being embedded in a full bed of hot asphalt/bitumen.

The term “four plies” refers to a four-ply roof membrane construction. Often, a base sheet, used as the bottom-most ply or layer, is mechanically fastened. Built-up roofs generally are considered fully adhered if applied directly to roof decks or insulation.
