Aliens

To get the best possible insulation in our new house we decided on spray foam for the roof areas. Instead of using typical batt insulation and a plastic vapour barrier at the ceiling level we instead are having the roof insulated (from the inside). The attic space is treated as interior conditioned space. The foam also acts as a vapour barrier. While we could have gone for R28 we opted go go above the required standard to R40. With the many potlights in our ceiling space a typical vapour barrier would have been virtually useless and very ineficcient.

The foam is sprayed on as a two part liquid which combines and then expands. While the two parts are toxic in their raw state they become inert and safe in place. But to do the application the ELEMENT Spray Foam team needs to wear protective gear. Colin and Ryan looked like aliens as they worked with bits of blue foam stuck to their coveralls and even handling a formidable gun.

We all steered clear of these guys in action!

I left just after lunch but it looks to me like they will be almost half way through the house by quitting time. The windows and doors are now less than a week away. I look forward to seeing them go into place at last.
