SIP or Structurally Insulated Panel buildings are tried and tested for house buildings and commercial structures. Factory fabricated and assembled on site, these fit snugly together with a historic ability to withstand the worst of British weather. Stud frame constructions are usually produced by a Carpenter by hand who arrives on site with a stock of timber (often untreated). Stud construction is normally used for non-supporting internal walls and can allow greater wall movement than a solid wall causing issues such as roof leaks and cracks between plasterboard joints internally.
