Our structures are made with a traditional framework, rather than SIPS (structural insulated panels). Although SIPS are quick to install, they can vibrate which we feel can compromise the strength and stability. We use Treated Tallanised timber for the stud-work with a PIR hard insulation in between.
Interior walls - a vapour control layer is used to eliminate condensation problems in the future.
Outside structure - 18mm OSB boarding is used and finished with a black, breathable membrane.
