Durability of Elastomeric Sealants

File Opener

Sealant is used in the exterior joints of every modern building, but usually incorrectly. Owners have high expectations for performance and durability, but premature sealant failure is common, resulting in air and water infiltration, property damage, and expensive repair work. Design details and installation practices contribute to the service life, but there is a bigger problem in the industry—many sealant products cannot resist movement and weathering, which are their core functions.

Dog Washing in Multi-family Housing

While tubs for dog washing are a common feature of veterinary clinics, kennels, and professional pet-grooming services, these products are increasingly being installed in locations where dog-owners can wash their own pets. Many multi-family housing developments, apartment buildings, and residential condominiums now offer dog-washing rooms in addition to exercise yards in an attempt to attract more animal-owning tenants.

Epoxy types: A guide for specifiers

Ideally, a bonded anchor should be installed into concrete of known compressive strength. Engineers who specify epoxy anchors also specify the compressive strength to ensure the epoxy can achieve its published bond strength.  If the compressive strength or overall integrity is unknown, they sometimes require field testing of the embedded anchor to determine if the concrete is good enough.

Epoxy types vary widely, and specifiers need to note such attributes as nozzle time, gel time, load time, sag, cure time, and chemical resistance—each property will affect what makes the product ideal for the intended application. When searching for the proper epoxy to specify, it is important to note there are three general classes—pure epoxy, polyester resins, and epoxy acrylates—that break out in different ways with respect to properties and performance.

Continuing Education on Continuous Insulation

continuous - Tom's article 2015 - 5th-&-Alton Shopping-Center

Continuous insulation (ci) has been a component of exterior wall assemblies for more than 40 years in North America and even longer in Europe. It has always been the smart way to design wall assemblies from the standpoint of energy conservation and water management. By minimizing energy loss caused by thermal bridging and the risk of condensation caused by water vapor diffusion, exterior ci can improve building durability and benefit the environment.
