Lintels – Fairfaced Fire Range

All Damp Proof Course details, Cavity Tray details and wall vents should be in accordance with the current building regulations and architects detailing.

For all spans greater than 1200mm the units should be propped and supported temporarily at 1200mm centres with the resulting 3 courses of masonry having time to cure before the recommencement of the building work where concrete floors are to be placed onto units, the units should be supported temporarily until the floors have been completed to reduce the risk of shock loading or uneven loading of the lintels.

All lintels should be lifted with threaded lifting loops to ensure that the units are supported and installed to ensure correct handling of the units at all times. Lifting Loops can be ordered through us should you require them.

Fairfaced Fire Range

This is the most recent range of lintels from King Stone Products. The lintels within this range can reach up to 240 minutes fire rating on varying sections without the need for a separate outer coating and also reduces the onsite handling risk. This lintel is made from a proportion of recycled products and is environmentally friendly. The range is verified by a professional fire testing organisation who has supplied literature to support our claim.

The lintels within the super fire rated range can reach up to 240 minutes fire rating on varying sections. This is the first lintel range to achieve 240 minutes on a 140mm wide section without the need for a separate outer coating. This range, that comes in wall thicknesses of 100mm, 140mm and 215mm, are available in all depths of our standard range and will carry the same loadings.

The lintels are constructed from a newly developed material that has enhanced thermal performance but maintains all the characteristics of normal concrete with a density of 2000kg/ m³. The material ensures that the surface is flawless and is fairfaced in its appearance. This revolutionary lintel has a very low cement content; only 2% and emits very little C02 during manufacture.

Due to a substantial amount of ingredients of the new material coming either from renewable sources or from recycled products means that the lintels green credentials are exceptionally high. This, coupled with the 4 hour fire rated resistance, which is guaranteed by an independent fire testing organisation make this an attractive product for the specifier. The material used is exclusive to King Stone Products. The use of the material means there is no need for an outer coating that may delaminate, get damaged in transit or require to be re-patched on site. It is simply a one part mix as are all our other lintels.

Our Load Tables are working loads and therefore have a degree of safety. All figures are in KN/m. – The tables are generated on the Mr of the section properties.
