While many companies are reluctant to change suppliers or materials – why change what works? Stack Modular is constantly striving to find higher quality and more cost effective products to offer our customers.

To properly evaluate new materials Stack has implemented a check list system for approval of new suppliers, new products and new materials.

  1. Does the product/material have the required certifications – (CWB, CSA, ASTM, UL etc.)?
  2. Does the supplier have all required product documentation – (Physical and/or chemical certifications, ISO, CWB certifications etc.)?
  3. Has the supplier’s manufacturing facility passed the Stack Modular on site audit?
  4. Has the supplier provided representative samples to Stack for testing?
  5. Has the product/material been tested on site under typical construction conditions?
  6. Did the product/material work as expected?
  7. Did the product or material require any changes in the normal usage or installation practice as compared to what is currently being used? If yes detail changes in the construction process and submit the report to the director of construction for review.
  8. How did installation time compare to current product?
  9. How did the quality of the finished assembly compare to current product?
  10. Final recommendation.

Over the past 2 months Stack has built several full sized rooms including a kitchen, a living room and a bathroom which were used to test dozens of potential cost savings – both initial material costs as well installation costs. These tests included the installation of a full scale kitchen, bathroom floor and wall tiles, tile corner trim, bathroom exhaust fans, dozens of different paints, primers and plaster, EZ fire tape, EZ trim, ACP exterior cladding, many different wall papers, LED lights, fire caulking, window and door profiles, door and window hardware and much more.

These tests have led to changes that will be implemented in Stack Modular’s 4 story, 48 apartment modular complex due to begin construction in late August and improve the final product and customer satisfaction: A quieter more cost effective bathroom fan, a new plaster (mud) that improves paint adhesion, a new tile corner trim that improves corner appearance, a new wall paper that installs faster and has a better corner finish and a new window profile are a few examples of improvements.
