The hunt for perfect insulation

Thanks to a friend of mine, Juha, we had the possibility to check our house insulation with enterprise grade thermal camera. Please notice that this gadget is a wee bit outside the ordinary gadget budget.

Gadget & Conditions


  • Date & time: Saturday 8th of March 2013, 20:10-21:10 GMT+2
  • Gadget: FLIR Systems AB ThermaCAM B-360
  • Conditions: Outside temp -12.5C, inside temp +22.2C - the bigger the thermal difference the better
  • Test subject: separate house, wood & concrete. Capacitive electrical heating; water tubing elements within 9-11 cm of concrete. Floor space is about 162 m2

So let the fun begin

That would be me... Predator like view

And the family dog (Cotton de Tulear)

This gadget can even see thru the floor; that is the water heating element buried under 6-7 cm of concrete, 1 cm laminate and 0,5cm padding..

Supporting framework behind the walls act as thermal conductor

Doors and windows are difficult; This door needs minor adjustement and new insulation

This door has major insulation issues; notice the thermal range on the bottom (temperatures between 3.4-20.4C) with matching colors - the coldest place is seen as dark blue with temperature as low as 3.4C. This needs to be fixed ASAP!

Strange location for cold spot... but the thermal range is not that bad though; ~18.2C is not that alarming.

Conclusion

Nothing alarming; just few doors needing better insulation and adjustments. It is important to observe the thermal range; cold spots may not be as cold as the coloring may suggest.
This kind of thermal imaging should be made mandatory for all houses; it takes just 1 hour and you can really easily spot the places that may need insulation improvements.
It is also noteworthy that cold spots are prone to condensed moisture and provide good conditions for mildew.
This is what I call cheap green thinking.
