Workingwith leading contractors, the company has developed three Jablite UnderfloorHeating panels for use with current underfloor heating systems and to meet thegrowing demand for underfloor heating in new build commercial and domesticapplications. Jablite UFH-L, Jablite UFH-C and Jablite UFH-M are suitable for bothdomestic and commercial applications.Key benefits of underfloorheating systems■ Clean interior design and maximumusable wall space■ Safer and cleaner than radiators as nodirect hot surfaces■ Dust and air movement is minimised■ Low maintenance systems■ Uniform heat distribution over thesurface area■ Hot and cold spots eliminatedEasy to handleJablite UFH panels are manufactured fromexpanded polystyrene (EPS) which islightweight and easy to handle on site.PermanentJablite UFH panels are rot-proof anddurable and will remain effective for thelife of the building. They also have theadvantage of being flood-proof.EnvironmentExpanded polystyrene has been awardedan A+ rating by the BRE’s Green Guide toSpecification.FireSolid ground floors are not required toprovide fire resistance. When properlyinstalled, Jablite UFH panels are fullyprotected by the screed or the chipboardand will have no adverse effect on the fireperformance of the floor. Euroclass E,flame-retardant additive material isavailable to order.U-valuesThe rate of heat loss through a groundfloor varies with its size and shape.The thickness of insulation required tomeet a given U-value will similarly dependon the size and shape of the floor.Approved Documents L1A , L1B, L2A andL2B guide you to BS EN ISO 13370 as themethod for determining floor U-valuesbased on the floor perimeter and floor areawhere: “P” is length of exposed perimeterin metres and “A” is floor area insquare metres.The measurement of both the floor areaand perimeter should be made on theinternal finished surface of the wallsenclosing the heated space; unheatedareas such as garages, porches and storagespaces need not be included. For buildingssuch as terraces or blocks of flatsand apartments, the measurementshould be taken over the total grossground-floor area.For technical information 0870 444 8769 technical@jablite.co.uk
82APPLICATION:Floor insulation – underfloor heating UFH-CProduct: Jablite UFH-CJablite UFH-C is a castellated floor panelsuitable for use in domestic andcommercial solid floor applications with ascreed finish. The panels form a simple gridto enable the quickest possible pipe layingand a precise guide for minimum bendingradius. The castellated shape sets the pipesat exact centres and holds the pipe againstmovement when screeding the floor.TypeJablite UFH-C panels are supplied as EPS150 as defined in BS EN 13163 – Reactionto Fire Class E, containing a flameretardant additive.U-valuesTables 15.7 – 15.12 show the standardthickness of Jabfloor 70, 100 and 150required to supplement the 58mm thickJablite UFH-C Panel to meet U-values of0.25, 0.22, 0.20, 0.18, 0.15, 0.10W/m 2 K.Where the Jablite UFH-C Panel achievesthe required U value on its own the text‘UFH-C’ has been placed in the table.These values are based on the followingk-values:Jabfloor 70Jabfloor 100Jabfloor 1500.038W/mK0.036W/mK0.035W/mKDimensionsBoard size overall: 1030 x 830mmThickness: 58mmBoard size cover: 1000 x 800mmThickness castellations: 25mmDiameter of castellations: 85mm
