Nu-span is a high performance, Precast , Insulated slab system for application in theconstruction of suspended ground Floors indwellings and smaller-scale commercialbuildings. It is manufactured in precision made steel moulds to stringent quality standards. The composite unit comprises structural grade reinforced concrete bonded to high performance expanded polystyrene (EPS). Nu-span was developed to meet the nextgeneration of building regulations and canachieve U-Values as low as W/m2 Kdepending on the perimeter/area ratio andinsulating material chosen.

2 This allows theWhy use ?Thermal Performance- The Unit provides a continuous unbroken layer of EPS material across the entire floor achieving U-values as low as A significant reduction in cold bridging is also achieved resulting in attractive Psi ( ) values as demonstrated in the technical data A choice of insulating material is available (type and thickness) to help achieve maximum thermal performance and energy rating for any building and assist in meeting the required Built-in benefits with maintenance free high U-values through an essential element of the building fabric achieving increasing standards required by Building Concrete is one of the most versatile, durable and cost effective building materials available. It is also environmentally sustainable with green credentials that outperform both steel and timber and, when combined with EPS, offers a floor system that significantly reduces the carbon footprint of any construction.

3 This is recognised by a BREAMM rating of A+. Composite UnitThe Nu-span Unit combines the three essential elements of any suspended ground floor: the structural element, the insulation and the arrives on site as one factory made unit with the following benefits:- No on-site storage issues for either insulation or the other components providing both a practical and an environmental benefit;- The insulation element is fitted to the Nu-span Unit in the factory thus removing the performance risk associated with the manual fitting of insulation materials on site (Actual performance in this regard is likely to be an increasing area of focus in forthcoming building regulations);- No further screed is required when using a timber batten floor and only a self-levelling compound is required for other finishes when using NS30 and NS38 & Cost Effective- Installation is carried out by experienced erection crews.

4 Up to 400m2 per day can be safely installed leaving an immediate safe working platform for follow-on CDM Compliance - The use of Nu-span designs out the risks associated with manual handling, trips, slips and falls thus considerably improving on-site Health & Safety. The Units are installed by experienced and certified erection No on-site material waste with associated cost benefits and reduced storage All-weather construction fitting is not restricted by adverse weather Flooring Limited boasts an excellent management team with decades of experience in the concrete product and thermal insulation markets.

The experienced Nu-span team is also available to carry out installation of the product resulting in a comprehensive solution for has been designed to have many benefits over traditional ground floor construction we areUspanUfloorsUchoicesbuilding designer greater flexibility whenspecifying other elements of the building inorder to achieve the required Target Emissions Rating (TER) or to achieve highly energy efficient is the ideal solution for suspendedground floor levels in domestic housing andsmaller scale commercial buildings,particularly where customers are seeking athermally efficient method of construction.

6 Atthe same time, due to the off-sitemanufacturing process, Nu-span provides fast on-site construction allowing the follow-on trades to get on site in as little as three hours for a typical detached NS30 and NS38 Units offer excellent thermal performance which is provided bybonding EPS material to the underside of the Precast well as offering excellent insulating properties, and extensively reducing cold bridging, the advanced design and material composition of the system makes a positive contribution to the reduction in CO2 by decreasing the amount of fossil fuel required to heat the thermal performance of each project is assessed in accordance with EN ISO 13370:1998 to ensure compliance. In addition: U- Values as low as W/m2K can be achieved depending on the P/A ratio; Substantial thermal mass; A significant reduction in thermal bridging is achieved; The Nu-span Technical Team is available from design stage to discuss advantages and application of the Nu-span floor system; and A choice of products is available depending on your budget and comparison with traditional solutionsForming suspended ground Floors with conventional T-Beam and Block construction methods makes it difficult to achieve the high standards of thermal performance necessary to comply with Building Regulations.

7 Some improvement in performance is possible by replacing the concrete blocks with EPS insulation units which are specifically shaped to make contact beneath the beams with an aim of providing a continuous layer of , even slight irregularities in setting-out can result in breaks in the insulation layer,leading to air movement around the units and increased heat loss. In addition, the perimeterof such systems is generally formed with concrete blocks with only a thin layer of insulation fixed beneath. This inevitably downgrades the performance of the complete EfficiencyJunctions The stringent requirements for energy efficient buildings means designers must consider not only heat loss which occurs through building elements (expressed by their U-values) but also the heat loss which occurs at the junctions between building elements, such as the wall-floor of the key factors in minimising heat loss at junctions is ensuring continuity of insulation at the junction.

8 This is difficult with conventional suspended floor constructions, as the floor insulation stops at the internal face of the wall and the insulation is often in the wall NS30 and NS38 Units reduce heat loss at the wall-floor junction. Because the units bear on the inner leaf of cavity walls, the insulation extends beyond the floor to the face of the wall cavity. The insulation within the cavity then butts that on the Nu-span Unit to give continuous insulation across the Advantage Nu-span NS30 and NS38 maximise the thermal performance of ground Floors by forming a deep, unbroken layer of insulation across the entire floor; The design of Nu-span NS30 and NS38 Units minimises the thermal bridging effect of the structural concrete to give a high thermal resistance for the suspended floor; Within the NS30 and NS38 units the structural concrete is cast onto the insulation, avoiding air gaps and therefore minimising heat loss by air movement; The insulation on each Nu-span NS30 or NS38 Unit is continuous and the Units are butted with their insulation layers tight together, thus avoiding gaps in the insulation layer.

9 And Nu-span NS30 and NS38 Units cover the entire floor area, providing the same performance across the entire is one of the most versatile, durable and cost effective building materials available. It is also environmentally sustainable with green credentials that outperform both steel and timber and, when combined with EPS, offers a floor system that helps reduce the building s carbon footprint. EPSThe energy used in the production of EPS (embodied energy) is saved many times over throughout the life of the building in which it is installed. Initial recovery is estimated to be within the first 15 years, thus reducing your dwelling s carbon footprint. The green credentials of EPS are Zero Ozone Depletion Potential ( ODP ) as the blowing agent used in the expansion process is Pentane which does not affect the Ozone layer;- Zero Global Warming Potential ( GWP ) 1 credit score towards the overall code level rating;- Green guide summary rating of A+ ;- Credit score of 3 for the floor element in the code for Sustainable Homes;- CFC and HCFC free;- 98% air;- Contains recycled material;- Fully recyclableEnvironmentalFire ResistanceThere are no fire resistance requirements needed when the Nu-span system is used on the ground floor of domestic houses.
