Anniversaries, pageviews and ISBU Home Building – A definition of Terms…

24 Oct

I recently received an email from a group congratulating me on hitting 1 MILLION pageviews, this year.

While we appreciate the acknowledgement, the truth is that we actually reset the counter on the anniversary of the blog each year, which is in MAY.  And, that number doesn’t include syndication, which accounts for a similar (in fact, LARGER) number of pageviews. RR has gotten several million pageviews since it’s origins, a few years ago.

So, if nothing else, we’re confident that the message is getting out there.

As a result, we get email. A TON of email. I had no idea when I started this blog that there would be so much email. Oy! 🙂

After reviewing my email (I have 4,000 emails – I’m not kidding – to sort though as I type this);

I thought that maybe it’d be beneficial to start defining the terms that we use here on Renaissance Ronin so often.

Most of my recent “questions” are about insulation. (I have 23 emails currently asking me the difference between SPF and fiberglass batts – the answer is simple; SPF is good. Fiberglass batts are BAD. :))

It’s pretty obvious that you need to insulate a shipping container, unless you want to turn it into an oven or a refrigerator (depending on season). Additionally Shipping Container (ISBU)  homes require ROOFS! That means that you need to insulate THEM, as well. Be they wood based, metal framed or something else… you guessed it… SPF is liberally applied to insure  that the home is efficient and warm.

We’re HUGE advocates of SPF – Spray on CLOSED CELL foam.

When we’re not using SPF, we’re using Rigid insulation that is basically the same (or a very similar) material, preformed into sheets that are applied directly to your structure.

SO, let’s start building a glossary of terms and materials, shall we?

Here’s a few for today;

Closed Cell Foam Structure – Foam with no holes or voids that water can penetrate. It resists moisture and will maintain its R-value over time. The result, high compressive strength and unparalleled resistance to water penetration.

R-Value – A measurement of resistance to heat flow. The greater the R-value, the greater the thermal efficiency—and a small increase makes a big difference. Cavity insulation (as depicted above) only insulates between the studs, leaving those studs un-insulated.

That un-insulated wood creates an effect called “thermal bridging”, which we’ll discuss again in great depth, as a later date.

Rigid insulation –  like SPF (that is applied by spraying it directly onto the surface of your building or residence),  is foam sheet material that covers the entire wall, providing a continuous layer of thermal protection and increasing the overall R-value and energy efficiency of your structure.

Stay tuned.
