i use bubble wrap for the outside to cover it and tarp over that:wave:
What do you use/ how do you do it?
Could I just nail some thick blankets to the walls - would that do anything?
Yes it would, but if it got wet it would take a long time to dry, you would need very good airflow.
You could use lots of things to line the hutch walls, get a thin layer of plywood (thicker the plywood the better), and put the blankets inside the frame and plywood. But you still would need good airflow.
Do you mean if a bun weed on it or something, or would it just get damp being in there?
Hmm maybe not fabric then, dont want any mould.
What would be better, bubble wrap, foil-coated bubble wrap, or polystyrene? I'm thinking for inside the hutch, boarded over with plywood. Outside is tricky because of wind and rain... might just use tarpaulin for that.
I've used this before: http://www.diy.com/nav/build/insula...ion-Silver-Length-7-5m-x-Width-600mm-10617653
Worked okay, used it with plywood and 3 vents.
Is that the same stuff as the £30 rolls? Sorry to be dense, but what do you mean by vents, and are they needed when insultating?
Not sure what the £30 rolls are, but i know different suppliers have similar stuff, some cost more but you get what you pay for. Screwfix have this: http://www.screwfix.com/p/airtec-double-insulation-1-5-x-25m/50913. Cost more, better quality but does same job but comes in a longer roll. You should only need one B&Q roll, you may even get to double it up inside, you should also only need one sheet of plywood for a 6ft x 2ft x 2ft hutch if you only do the sides and back.
If you want, measure the hutch, back, sides, roof and floor (roof and floor if you plan to insulate that) and reply to this topic and i'll help you work out how much plywood you need.
As for the vents, if you insulate without good airflow, you stand a good chance of getting damp during colder months. Vents like this: http://www.screwfix.com/p/manrose-louvre-vent-white-229mm-x-152mm/16105 but you can get some for 70ish pence.
Sorry, I meant this stuff, which is available in a bigger £30 roll. http://www.diy.com/nav/build/insula...awrap-Loft-Insulation-11597554?skuId=12108260
Thanks, I've measured the hutch before, and its just your basic 6x2. The meshed area has a back wall of 4x2, the sleeping area 2x2, theres a divider inbetween so I'd have to do each section separately. The sides of the hutch go about 23 inches deep and its all roughly 2ft high (the front is slightly higher but because of the way the extra height is a part of the roof panel it couldnt be insulated anyway, sorry I know that makes no sense, its just an awkward recessed wedge-shape attached to the underneath of the roof.) The roof... I'm not sure if I'd want to do the roof, as its very thick and on the inside of the hutch it is metalic colour and cool to the touch, so I'm not sure if the roof has already been insulated perhaps.
What are the best (or better) materials for insulating the hutch? And does the shiny foil-coated bubblewrap stuff work as well if you cover it up with wood? Because surely then it cant reflect back the heat as well :?
Yes that stuff is fine, as for will the stuff work if covered in wood, yes. Heat travels though wood and Thermawrap Insulation will reflect it back.
You should only need 1 sheet of plywood, a sheet that is 1220x2440mm (4ft x 8ft).
