Reflecting on Heat Transfer Reduction

Prodex-Renault motors

Most forms of building insulation—fiberglass, mineral fibers, cellulose, and cellular plastic—play a key role in making buildings energy-efficient and in reducing electrical peak demand. However, the amount of material that can be added to building walls or roof-ceiling assemblies is limited either by physical dimensions of the framing (ceiling frames) or adverse effects of over-insulating (weight, heat and moisture retention, and ventilation restrictions).

A Look at Cool Roof Options

Providing roofs with a reflective surface is not a new concept. For example, asphalt coatings with leafing aluminum pigment have always promoted the benefit of reducing interior temperatures while slowing the oxidation of the waterproofing membrane. However, the term ‘cool roofing’ was more recently coined with the increased focus on the reduction of energy consumption. This article examines options from built-up roofs (BURs) to modified-bitumen (mod-bit) systems to single-ply membranes.

Parking decks must be protected from the harmful effects of moisture and chlorides, but there is a growing preconception installing a traffic-bearing membrane is a one-way ticket to the garage equivalent of immortality. While a traffic-bearing membrane may work in many situations, consideration is necessary to determine if this costly investment is the correct solution for the garage’s needs. Identifying product properties and applying appropriate selection criteria can help specifiers develop solutions that protect now, while considering treatment options for the future.

Metal Wall Panels on the Roof: How to achieve durability and reliability using sheet metal

Some modern architectural designs use newer materials and metal panel assemblies for roofing applications, many of which are not intended to be used as roofing and, therefore, may not be well-suited for it. One such trend is the use of architectural metal wall panels as roofing to create a visually seamless transition between building walls and roof surfaces such as low-slope setbacks in the façade. This can impose unique challenges for the designer and contractor.

Minimizing Risks with Solar Roofs

Commercial low-slope rooftops are an attractive platform for the installation of solar photovoltaic (PV) electricity-producing systems. Nevertheless, a roof’s function is, first and foremost, to protect the building’s contents and people from the elements. In this regard, design professionals need to anticipate the potential risks associated with the installation of roof-mounted PV arrays. This sort of due diligence is particularly important when installing PV systems on existing warranted roofs.
