{"product_id":"fortis-sip-workshop-style-b","title":"Fortis SIP Workshop Style B | End Door Insulated Garden Workshop","description":"\u003cp\u003eThe Fortis SIP Workshop Style B 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 B is the mirror-image layout of Style A, with the door in the opposite end wall and windows along the front — choose whichever suits where the building sits in your garden and how you approach it. 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 in the end wall, opening windows along the front (mirror image of Style A)\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.
