Manufactures of high quality engineered roof trusses, metal web floor joists, timber framed building

JSI Timber Frame Ltd based in Pembrokeshire, South Wales is run by Nathen Houston, a time served carpenter with more than 20 years experience within Pembrokeshire, Carmarthenshire, Ceredigion and South Wales. At JSI Timber Frames, we employ computer aided design to engineer roof trusses and SpaceJoist open web joists to exacting standards of high quality and value. Recent investment in our Pembrokeshire manufacturing plant has grown floor space to 5500 sq ft to accommodate higher roof truss and SpaceJoist production capacity. Additionally, with over 25 years of experience in carpentry on site, JSI provide a skilled installation service and advice where required
