High Performance Lintels for harsh environments
L1 type lintels have a ‘top hat’ profile which offers distinct advantages in terms of durability and structural characteristics including: The maintenance of the integrity of the wall structure and its thermal properties through uniform and continuous bricklaying the upstand of the lintel sits within the cavity;

A unique single element cavity tray system
Indented flange for plaster key
Excellent thermal efficiency as a direct result of its design which, with the addition of an expanded polystyrene infill (standard on allL1 lintels) , provides a ‘U’ value through the lintel of significantly less than 0.33 W/m2 K; Reduced maintenance costs through the elimination of cracked plaster due to the differential expansion of dissimilar materials associated with Box section lintels. Semi-pierced slots on the inner flange give an excellent key for the plaster finish.

To achieve the loading figures shown, the L7 lintel must be secured with restraining clips and a block /batten (not supplied) must be used to prevent lateral deflection (twist) during the building stage. A single block/batten 300mm long at mid span will be sufficient. Restraining clips should be fixed with 3.3 x 50mm galvanised nails at no more than 500mm centres each side of mid span. Clips should be positioned with their vertical centres at the top of the lintel to allow for lintel movement and shrinkage of timber frame.

Designed to provide a quick and safe method of spanning small openings (up to 1000mm) in internal walls, IG internal lintels are both economical and easy to store, carry and use. When a minimum height of 152mm of brick/blockwork with well-filled joints of cement mortar is built over the lintel, the construction will be load-bearing for normal domestic building purposes after curing. The loading capacity of the lintel can be increased by increasing the height of the walling built across it.
In some circumstances these lintels may have an expanded metal lathing attached and may differ from the diagram shown.
Care should be taken to avoid shock loading when used with concrete floor or other heavy units. Perforated steel for plaster key

NOTE: The Flange of the Box 200 (or HD Box 200) is designed to support a nominal masonry load only, up to a maximum of 3kN/m run.

Lintel Soffit Cladding
Stainless Steel Lintels High Performance for harsh environments
Manufactured from rigid PVC to match UPVC window frames, the IG lintel soffit cladding is designed to clip over the front flange of the external wall lintel to provide an aesthetically pleasing appearance to the exposed outer flange.
• IG standard lintels are available in stainless steel.
Supplied in white (type SCW) and brown (type SCB), soffit cladding is available in lengths to meet all standard openings, for example a 1500 mm length is available to fit a structural opening width of 1200 mm. The cladding simply clips into place - no special tools are required.
• Outstanding durability through austenitic chromium nickel steel to BS EN 10088-2 1.4301 (304S15).
Note: When soffit cladding is used, external wall lintels must be installed with a flexible damp proof course (DPC) which must project beyond the front face of the cladding.
• Suitable for use in coastal and industrial environments. • All IG galvanised steel loading tables apply.

Universal Arch
Special Lintel Enquiry Fax Back Please complete and fax back the form overleaf...
When low rise arches are required in brickwork above openings, the IG Universal Arch provides the ideal former for the bricklayer. Vacuum-formed from white pigmented, external weathering quality, impact resistant polystyrene. Suitable for use in cavity walls and with timber frame construction, the unit is designed to sit on any steel lintel with an outer flange of 90mm to 95mm. The design provides an arch rise of 75mm for arch spans from 475mm to 1785mm, and a rise of 150mm for arch spans from 1916mm to 2725mm.

IG’s comprehensive range of standard lintels covers all applications in conventional building constructions. When a building requires more unconventional support solutions, IG has the expertise to design and manufacture special lintels that suit all shapes and sizes. These special lintels some of which feature below - can include radius, natural arch, gothic arch, corner, apex, cant brick, ‘I’ beam, 200mm-wide inner leaf, feature plate and wider cavity.
IG’s Special Lintel Service is the product of a wide experience in successfully meeting the needs of architects of both domestic and commercial buildings. It embraces every aspect of lintel design and supply, from calculation of shape, size and loading to coordination with construction scheduling and consideration of budgetary requirement. IG’s ultimate aim is to provide the most cost-effective design solution to special lintel problems. In order to best utilise this free service, please ensure that all relevant details are provided i.e. wall construction (outer leaf, cavity, inner leaf), clear spans, arch rise, radius and any other factor which may affect the special lintel design and costing.
When loading figures are not available, then please provide a full set of drawings including: (a) plans (b) elevations (c) sections (d) wall construction (e) floor construction and direction This information will enable our design engineers to calculate the relevant loadings. Information can be sent directly to the Technical Department by email: info@igltd.co.uk or by fax back on 01633 486495.
