Our PIR Insulation Boards arrived

What a day! We got a call from Rembrand asking if they could deliver the PIR boards we ordered a day earlier. Sure they can! We quickly made space and waited fo the truck to deliver.

In my calculation the complete pile of boards would sum up to roughly 8m. Quite a load – especially with today’s wind! The truck actually did a tour just for us …

And then we drove the load over to our plot – all the way from the main road. It took four round trips to get everything (64 * 2400 x 1200 x 90mm, 20 * 2400 x 1200 x 140mm) into the barn.

And then we had to find space to store them …

Our insulation baords all across the barn

Luckily, we designed the hallway of our tiny-house-in-barn with a 1450mm width and all doors 1080mm wide. Enough space to store some of the boards in one of our just ready-laminated rooms on the first floor. No problem lifting it with the TeleHandler!

When we ordered from Rembrand the actual manufacturer was not specified. But upon delivery we could see the brand – IKO. According to their web site the thermal conductivity lambda for the material is 0.022 W/mK. For the walls this gives us a U-value of 0.18 W/m2K. Just what the building code asks for …

For the floor things look even better – with thicker boards the calculated U-value fits the requirement of the code as well: 0.13W/m2K. And this does not include our laminate floor and the insulation layer under it.

So, now we just have to choose what to do next. Installing the roof, continue with flooring or start insulating the walls …
