Shipping Container Classroom With Low U Values
An architect contacted us regarding a 20ft container classroom that was to be placed in a public park allotment in Scotland, he had some drawings to illustrate what his client required. His client also required a 10ft container for storage.
Initially it seemed that only a basic specification for electrics, lining, side removal and linking was required. However, it quickly became apparent that this build required certain U values for building control to approve it. After some extensive research, we sourced suppliers who could provide the appropriate materials. For example, the walls and roof had to have a 0.16 U value, so we could not use our regular melamine lining as this gave a higher U value. So, we used Speedline thermal laminate lining, which we built up to 172.5mm. This was a lot more costly than regular melamine, but without it, the build would not have been approved. The majority of our builds that require windows use standard anti-vandal windows, but here we needed windows with a 1.1 U value, so triple glazed windows were used. A final specification was presented to the architect, and it was a whole year later when this was approved, and the job booked in with us.
The client required a canopy and a wood burner which they were going to fit themselves. For the wood burner, we created a flue aperture in the roof and installed 12mm protective Supalux board. We also installed a kitchen which consisted of a sink, cold tap, water heater with hot tap, water in and out, work surface, cupboards and a waste out.
Because the park was in Scotland, we did not do our usual initial site visit, so relied on lots of photographs when it came to delivery approval. We had to be aware of the public who were using the park, had to negotiate a large bollard that was placed in the road access location, and also the ground, which had become quite muddy. Although delivery was possible, when our fabrications manager attended site ready for delivery, he worked out an alternative access route which was a lot quicker and missed out large sections of the park. The architect’s client was in attendance when delivery and container linking was taking place, and they were extremely happy with the smooth process as well as the units themselves.
Due to the tight regulations, and the ongoing correspondence between the architect, client, building control and us, this build took 9 weeks in total from payment to delivery, which is longer than our usual build time. However, without this extra time spent, the build would not have been approved.
