Application

  • Single leaf lintels for use in internal and external cavity or solid wall construction to support walls, floors and roofs above window and door openings.
  • Solid wall construction.
  • Lintels should be installed with a minimum end bearing of 150 mm, bedded on mortar and levelled along its length and across its width.
  • The masonry above the lintel should be built in accordance with BS EN 1996-2.
  • Masonry should be laid on a mortar bed and all perpendicular joints should be filled.
  • Allow the mortar to cure before applying floor or roof loads (temporary propping beneath a steel lintel is practised to facilitate speed of construction).
  • NHBC & LABC recommend a damp proof course (DPC) or cavity tray should be installed over all openings in external cavity walls.
  • Point loads should not be applied directly onto lintel flanges. Lintels should have a minimum of 150 mm masonry between the flange and the application level of any form of loading. Consult IG’s Technical Department if applying a point load above a lintel.
  • The lintel flange must project beyond the window/door frame and it is recommended that a flexible sealing compound is used between the underside of the lintel flange and the frame.
  • Do not cut lintels to length or modify them in any way without consulting an IG engineer.  
  • Masonry should not overhang any flange by more than 25 mm.  
  • The practice of propping a lintel is sometimes used to facilitate speed of construction. It should only be introduced after initial masonry load has been applied to the lintel. 
  • Stop ends are required at each end of a lintel to prevent moisture cascading over the ends into the cavity and onto the inside wall.
  • At least two weep vents are required per opening and positioned not more than 450 mm apart. 

Description

All IG standard lintels satisfy the thermal performance requirements of Approved Document L of the Building Regulations (E & W), Northern Ireland’s Technical Booklet F and Scotland’s Technical Handbook, section 6. Provide a damp proof course / cavity tray over all lintels. 


For more detailed information applicable to a particular wall construction, contact IG Lintels Technical Department. Refer to manufacturers literature for details regarding lintel ranges, height, thickness and Uniformly Distributed Load (UDL) figures.


Performance:

Fire:

  • IG lintels have been subjected to a fire test (WARRES No. 101263) in accordance with BS 476-20 and (Report No. 508704/R) in accordance with BS EN 1363-1 at Exova Warrington Fire and achieved a one hour fire performance.

Corrosion:

  • IG’s single leaf range of lintels are manufactured from high quality grade pre-galvanized mild steel to BS EN 10346 DX51D with a zinc coating of 600 g/m² (including both sides) conforming to BS EN 845-2.
  • The use of austenitic stainless steel is ideal when the life expectancy and maintenance programme of a building are key considerations.  
  • Material / coating specification in buildings exceeding three storeys in a non-aggressive environment should be limited to austenitic stainless steel (chrome nickel alloys).  
  • Material / coating specification for buildings in an aggressive environment (e.g. coastal sites) should be limited to austenitic stainless steel (molybdenum chrome nickel alloys). 

Structural:

  • The IG lintel range has safe working loads as detailed in each applicable loading table in the IG Lintels Product Guide brochure.
  • The structural performance figures within each table have been ascertained by testing in accordance with the requirements of standards BS EN 5977-2, BS EN 846-9 and BS EN 845-2.

Certification:

  • BBA Agrement certificate 05/4192 including regular assessment of production.
  • UKCA assessment of performance, system 3.
  • CE assessment of performance, system 3.
  • EN 1090-2 Execution Class 2, declaration method 1,2,3a & 3b, Certificate 14/F106 & 14/F107.
  • ISO 9001 Quality Management Systems, Certificate 18/Q059.
  • ISO 14001 Environmental Management Systems, Certificate 18/E019.
