This week involved a lot of figuring things out, so it feels as though we didn’t get an awful lot done at the site. However, the thought processes and discussions we have had have allowed us to develop the next steps in the sequence of things, which is very important in terms of logistics. For instance, leaving the cladding process for too long means that your building paper, insulation and framing may get wet, or the paper may sustain UV damage from the sun.(1) If the roof fascia or barge board is put on before the cladding, this can lead to insufficient water tightness of the building.(1) So, long story short; we needed to think about cladding the place. The first issue with this: the scaffolding Tom finished putting up the week before is attached to the frame, so this would need to be moved to put the cladding on. He did this over the course of the weekend, spending yet more time digging holes in the stony, unforgiving ground to put pegs into, and attaching the scaffolding to these.
The second issue was the windows and doors. Because we have decided that we need a cavity, the windows will not be mounted directly into the frame, due to the gap caused by said cavity. This means you need to put in a window support bar, which takes the weight of the window so it is not supported by the cladding. As far as I am aware, the window supports cannot just be purchased from a hardware store, you have to get these from a window manufacturer. This is one of the things we will have to look into over the week. We also started the grinding down of the windows this weekend. There is a lip on the inside frame which will make cladding and inserting the windows an absolute pain, so we decided to take this off with an angle grinder. Tom did the first cut, which looked great. I attempted the second one, which was…. less great. In fact, trending more towards terrible. Given my lack of experience with an angle grinder (the first time I had used one was the day before, when I’d ground off the nails sticking out of the frame so the plywood would go on nicely), I gave myself 1mm of grace, which turned out to be a very good idea! Luckily, Tom was able to come along and fix my wonky line using a sanding disk rather than a cutting disk on the grinder. I decided to employ a similar tactic with the other cuts, rather than rely on being precise with the cuts (which turned out to be an extremely good idea).

We also inserted the windows into the frame to see how they would fit once the plywood is fitted. There was enough room for us to fit a small reveal, with the window able to be tacked onto the framing with sufficient stability. Along with the support bar, this should be more than adequate strengthening to hold up the windows.
The other thing we did over the weekend was to get a quote for a roof. We went to a company called Metalcraft for this, simply because they were the only ones open when we got around to it at 4pm on Friday afternoon. The sales rep was very nice, despite us turning up at what must have been perilously close to home time with very little idea what we were after. Nevertheless, we have a quote for a roof coming with a trapezoidal cut, due to the relatively low pitch of approximately 6 degrees, and square guttering which should be good for when we move the trailer (based on nothing more scientific than the fact that they sit closer in, and look more ‘streamlined’ than the round ones). We also forgot to tell the sales rep that we had a chimney going in, so some examination of the plans to determine exactly where this will go is needed. I got some color samples to take away and look at too. I am currently coming to terms with the fact that the most environmentally friendly color is not the most aesthetically pleasing one – originally, my plan was for a dark, slate colored roof. However, light rooves reflect solar energy from the sun back into the atmosphere, which also contributes to keeping the house cooler in warm temperatures. They also can keep the house warmer, by emitting less heat as radiation than dark colors (although slightly less energy may be absorbed on sunny winter days, as most will be reflected). I am currently reevaluating my design plans to incorporate the lighter roof color while matching with cladding. At least, no matter what color it is, the product is Coloursteel, which comes with a quality guarantee and warranty.

Tom also did some insulating in the caravan over the course of the weekend. We arrived at the site at about 10.30pm on Friday night, after ordering the roof, and picking up some spare pallets on the side of the road on the way home. It was absolutely freezing when we arrived, and, despite putting the heater on when we got there, neither of us really warmed up over the course of the night. This ended up with Tom turning on the heater at 6am on Saturday morning to warm us up. That evening, he pilfered some of the spare Batts purchased for the walls, and packed them into the storage space underneath the caravan bed. Although Saturday was a slightly warmer night, I felt much toastier after his endeavors. Hopefully we will be able to survive caravan in winter – although I suppose if not, it should at least motivate us to get the house finished faster!
