As multi-family developers and design teams strive to increase urban density in a way that is affordable, wood framing continues to appear as a popular material choice. For the Stella luxury development in Marina del Rey, California, an innovative light wood-frame design allowed the team to stay within budget, while still meeting code requirements, and providing resort-style amenities in one of the highest seismic areas of the country.

Choosing appropriate UL designs      

Architect designing on drafting table

Many UL designs have load restrictions—a matter of great importance and potential liability for engineers of record (EORs), who, in accordance with several building codes and the UL Fire-Resistance Rating Directory, are responsible for identifying and approving the use of such designs on a project. Understanding which designs are restricted, and calculating the load restrictions, can be a complex process.

Specifying aluminum stretch forming


Stretch forming is a process in which s metal extrusion is kept under constant tension, while stretched and bent simultaneously over a die to create contoured parts. The variety of shapes and cross-sections that can be stretch-formed is almost unlimited. Window systems, skylights, storefronts, signs, flashings, curtain walls, walkway enclosures, and hand railings can be accurately and precisely formed to the desired shapes.

How does TPO stand up to accelerated weathering?


When it comes to roofing material, it is helpful to know the length of its lifespan—after all, no one can afford to put on a new membrane and simply wait to see how long it lasts. Building owners need assurance of roof lifespan so they can determine when a replacement might be needed, and manufacturers need to determine membrane warranty.

The future of roofing insulation


When it comes to insulating a facility, insulation addresses two important goals—maintaining a consistent interior temperature and preventing moisture from forming and collecting via condensation.There are several different materials and ways to protect a roof, including fiberglass, rigid board, and insulated metal panels (IMPs). Costs and benefits may vary between the products, but an overall building envelope comparison shows some marked differences.
