Cheers to Martin Holladay for his excellent article in Green Building Advisor, unmasking the top ten bad products relating to home energy. The article is a "must read" but the list is made up of:
- Tyvek ThermaWrap
- Fafco plastic solar collectors
- Passive fresh air inlets
- Vinyl siding laminated to rigid foam
- Powered attic ventilators
- Programmable thermostats
- Inexpensive LED lamps
- Foil-faced bubble wrap
- Power factor correction devices
- Vent-free gas space heaters
See his full post here.
