Finishing the trailer door

If you’ve been following along, we installed a new door on our trailer back in September. Although the door was fully functional, there were still several details to take care of before it gets too cold. These were finishing and insulating the new interior step and insulating and covering the framing on the outside, both of which have now been accomplished.

Let us begin with the interior work first, as that was completed first.

I laid down some vapour barrier and then cut some pieces of rigid insulation. This time I used some 1.5″ (38mm) rigid insulation I had lying around as left overs from other projects. The rest of the floor in the trailer is only 1″ (25mm) but this was a small space and I had enough of the thicker insulation. Why not, as they say.

After filling in the floor space with the rigid insulation, I wrapped the vapour barrier around the end and covered the top of it. This means we have two layers of vapour barrier in the step. I tuck taped it all down and made sure all of the gaps were covered.

After that, we needed to put a floor on it. We didn’t have any more of the laminate flooring left from doing the rest of the trailer, so we had decided to just buy another box of whatever laminate and not care too much about it matching in colour. Well, as it turns out, some friends of ours had a left-over box of laminate from a previous project so we bought it from them for $20.

And voila! New floor installed.

But wait! That’s not all. We also put in some fancy trim pieces to make it all snazzy looking. This was stage one.

Stage two involved finding something to go over the top corner edge that you can see is still exposed and quite sizeable in the picture above. They have these nice finishing strips at the hardware store that are about 8mm (5/16″) thick and 51mm (2″) wide. I couldn’t get a corner piece of molding to cover it as the gap it needed to cover was too big but I essentially made one by using two pieces of the aforementioned finishing strips.

We also added a metal bullnose cover to the outer edge against the door.

It turned out pretty nice, if we do say so ourselves. There may be some other fiddling around the old door to clean up the look, but that will be further down the line. At least we have a proper step with insulation and flooring now.

Next, it was the outside portion that needed some work. This is what we started with.

There is the basic framing with a plywood cover over it. You can also see that the plywood doesn’t cover the whole thing. That is what I did first: finish covering the top and both sides with plywood.

With the plywood installed, I pulled out the spray foam and made sure that all gaps between the framing and the trailer were filled.

After that, it was vapour barrier time again. Unfortunately, I don’t have a picture of that stage, but I wrapped both sides and top with 6mil before continuing on to the insulation.

Here is a picture of the insulation going on. The right side and top are complete, but the left still needs to insulated.

I had a full sheet of 25mm (1″) rigid insulation that I cut up for the sides and I found enough pieces to do 51mm (2″) on the top. I taped up all of the seams and it started to look pretty snug.

Over top of the insulation we put more plywood sheathing. We did that so we would have something solid to attach the finishing pieces to.

Because the door is made of cedar, we went with cedar tongue-and-groove to finish the outside. It didn’t take much, just too full bundles to cover all of the exposed parts. I also added some trim around the outside.

Some other stuff that we don’t have pictures of is the weather stripping we installed around the door jam to seal it and we added a rubbery-plastic door nose thingy underneath the bottom of the door so there isn’t a big gaping hole to the outside world there any more.

Overall, we’re really happy with out it turned out. Kat plans to add some varnish on the new wood as well, so that should protect it from the elements. As long as we can get that part finished before it gets too cold.
