Good Drainage Planes stop Capillary Action

We use drainage gaps or planes in wall systems to stop water from entering the building shell and causing deterioration or mould.

By Trish Holder

  • The promise of lower energy costs
  • The attractive renewable energy tax credits, which make it easier to come to terms with the rather exorbitant cost
  • The belief that this is truly a more…

Why do we have Sizing Limits?

There are not as many contractors out there as you would expect that are current with the most recent, and always updating, residential building code.  Particularly when it comes to the sizing limitations for HVAC equipment, most contractors consider this minimum requirement by law nothing more than a nuisance.  There is nothing more frustrating to see in a quality control role than a system that was sold, sized, and installed prior to the start of the system design process.  Completing a…

LED Lighting, 6-month update

Background

Ok, back in November 2012 I stumbled into my local 'big-box' home improvement store with an extra $1,000 USD to burn and without any research or pre-planning I purchased 35 LED bulbs to replace my incandescent and CFL bulbs.

At a burn time average of 3-hours per day that is 22-45 years of…
