{"product_id":"fortis-sip-workshop-style-c","title":"Fortis SIP Workshop Style C | Front Door Insulated Garden Workshop","description":"\u003cp\u003eThe Fortis SIP Workshop Style C is a fully insulated garden building made from Structural Insulated Panels through the walls, roof and floor, so it stays warmer in winter and cooler in summer — ready for year-round use as a workshop, home office, studio or gym. Style C puts the door and a window side by side on the front, with solid end walls — a neat fit where the building sits between a fence and a border. Its slim 72mm walls give thermal resistance comparable to around 200mm of solid log walling, finished with an engineered LP SmartSide timber exterior supplied primed for your own colour, a Hi Pent EPDM rubber roof and a steel-reinforced uPVC door and windows in Anthracite Grey.\u003c\/p\u003e\n\u003ch2 style=\"font-size: 1rem;\"\u003eProduct Details\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSizes:\u003c\/strong\u003e 8x8, 8x12, 8x16 and 8x20 — all 8ft (2440mm) deep, from 2562mm to 6222mm wide\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLayout:\u003c\/strong\u003e Door and opening window on the front, solid end walls\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eConstruction:\u003c\/strong\u003e Structural Insulated Panels (SIPs) through the walls, roof and floor\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWalls:\u003c\/strong\u003e 72mm SIP — LP SmartSide engineered exterior, 50mm graphite-enhanced EPS insulation, 11mm OSB3 interior (U-value 0.50 W\/m²K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eRoof:\u003c\/strong\u003e 122mm SIP Hi Pent with 100mm insulation and a supplied EPDM rubber covering (U-value 0.27 W\/m²K)\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFloor:\u003c\/strong\u003e 72mm insulated SIP with a 12mm exterior-grade plywood surface (EN 314-2 Class 3) on pressure-treated bearers\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDoor:\u003c\/strong\u003e Steel-reinforced uPVC with multipoint locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWindows:\u003c\/strong\u003e Opening uPVC (Rehau Total 70) with 28mm toughened double-glazed units and two-position locking\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eFrame colour:\u003c\/strong\u003e Anthracite Grey (RAL 7016) grained foil\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eExterior:\u003c\/strong\u003e Factory primed, ready to paint in your choice of colour\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eInterior:\u003c\/strong\u003e OSB walls and plywood floor — leave as is for a workshop or finish to suit an office or studio\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eElectrics:\u003c\/strong\u003e Not included — any supply must be fitted by a qualified electrician\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDelivery:\u003c\/strong\u003e Free UK mainland delivery — some remote postcodes may carry a surcharge, shown when you enter your postcode on this page\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSupplier:\u003c\/strong\u003e Shire\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003eU-values are calculated centre-of-panel figures for each element, and the log-wall comparison relates to thermal resistance only.
