Another enquiry into SIPs and electrical:
"I would like to use ultra thin LEDs, but I keep reading that I should go with surface mounted LED strips and not recessed. Are there any new LED products out there that would work for recessed? I'm putting in 1.5" T&G prior to SIP roof, so hoping that would create enough space for the lights. Thank you for your time. "
Response:
"If you intend to leave SIP roof panels exposed, and therefore intend to cut holes in the OSB facing board, you are compromising the structural member, keeping your roof up. This still can be done, but needs to be assessed by structural engineer. There may be limitations stipulated by manufacturer as well, like max size and number of penetrations per panel, min. distance from edge of each panel... It is more likely you will be able to penetrate facing board if you are using timber splines at the joints, therefor 'reinforced SIP rood'.
But if you are lining the panels with T&G you might just be able to fit something slim enough within the thickness of the lining. Some low profile LEDs can be 20mm deep all together, so no penetration in SIP roof required. Or if budget allows have a small timber batten behind T&G to run cables on the surface of your SIP roof, and this will make you sparky very happy too =)"
