What does stucco tape failure look like?

In stucco applications, tape failure can take a few different forms. The most common is adhesive residue. Residue occurs when the stucco tape’s adhesive coating begins to transfer to the window, door frame, or other surface that it is adhered to because of environmental changes, like fluctuations in temperature or sunlight exposure. If residue occurs, the contractor may have to re-do part of the stucco application all over again, costing valuable time. Another form of stucco tape failure is when the tape begins to fall off the window or door frame. This happens primarily when the tape expands during...

How is tape used to seal reflective insulation on HVAC systems?

The ability of reflective insulation on HVAC ducts hinges on the effectiveness of the tape used to seal it. Installing reflective insulation to achieve a high R-value when it is used on HVAC ductwork involves taping 2-3 inch wide strips of reflective insulation around the circumference of the air duct along the length of the duct at certain intervals, leaving a gap in between that is critical to achieving and maintaining a high R-value. Foil tape is used to secure these strips of insulation as well as to seal an outer layer of reflective insulation that will cover the...

Mission: HVAC 2017 – Challenge 3: Up to Code

Chris: Safety First For this mission, I interviewed local code enforcement officer Steven Gowan, who works for the City of Auburn. Q1: What does it mean to be code compliant? A: Code compliance is all about public safety. Without building codes, there would be no way to verify whether or not a building, or in our case, an HVAC system install is structurally or mechanically sound. Q2: What are some examples of HVAC codes? A: Whole House Ventilation is the first thing that comes to mind. Energy efficiency is a very hot topic now, so residential buildings are required...

How are stucco tapes tested?

Stucco tapes go through a variety of both physical tests and application tests. Physical tests ensure that the tapes perform at the required specification limits for shear, stretch, strength, and adhesion. These types of tests are common procedures for many different types of tape. Application testing is designed to provide an idea of how the tape will fare when it is used by contractors on the job. Application testing occurs on several different types of surfaces that the stucco tape might be adhered to during stucco application, including vinyl, aluminum, and wood. It is also tested against many different...

Mission: HVAC – Challenge 2: HVAC around the Nation

Have you ever had your Air Conditioning unit malfunction during the hottest week of summer? Ever come home to a freezing house after your heater breaks down in the dead of winter? You know that a broken-down HVAC system is no joke, and depending on where you live, the consequences can be severe. For their second mission, our Mission: HVAC students explained how each of their local climates impact the job, the tools they need, and considerations that technicians need to make during breakdown season. They also interviewed experienced professionals to better understand the differences between HVAC work around...
