Wayne State University is a nationally recognized metropolitan research institution with nearly 32,000 students. Annual maintenance evaluations identified a number of buildings on the campus with leaking roofs. This case study looks into four of these buildings that underwent a re-roof or re-cover application where the ROXUL asphalt coated stone wool insulation was installed. The result of these upgrades resolved the water penetration issues and improved the long-term thermal performance of the roof assembly.

Project Overview

Wayne State University is a nationally recognized metropolitan research institution with nearly 32,000 students. Annual maintenance evaluations identified a number of buildings on the campus with leaking roofs. This case study looks into four of these buildings that underwent a re-roof or re-cover application where the ROXUL asphalt coated stone wool insulation was installed. The result of these upgrades resolved the water penetration issues and improved the long-term thermal performance of the roof assembly.

ROXUL® Products Installed 

TOPROCK® DD Plus is a rigid dual-density stone wool board insulation, impregnated with a bitumen coating which is compatible with torch or mop applied membranes. MonoBoard™ Plus is a rigid uniform density, bitumen coated stone wool insulating coverboard.

Why TOPROCK® DD Plus and MONOBOARD® Plus were Chosen for this Project

The ROXUL exclusive dual-density TOPROCK DD Plus with a higher density top layer, provided a strong point load resistance and effective load distribution - adding durability to the new re-roof/re-cover assemblies. In order to meet the new ASHRAE standards, the addition of stone wool insulation was a cost effective method for Wayne State University to both repair water penetration and improve the energy efficiency of all four buildings.

Benefits of ROXUL Insulation

ROXUL stone wool insulation, has a long term stable R-value, is dimensionally stable, non-combustible, water repellent, non-corrosive, sound absorbent, will not promote fungi growth, contains no blowing agents or fire retardants, and is environmentally sustainable.
