130-145mm Cavity Standard Duty

IG L1/S 130 cavity wall lintels are supplied fully insulated. To further minimise any thermal bridging the lintels are designed without a non-continuous thermal break plate. Basically, the inner leaf is warmer as it has no contact with the cold outside leaf.


• Made from high quality galvanised steel

• Built in DPC saves time in construction and means cavity is easy to clean without risk of damage to DPC

• Built in plaster key with staggered slots applied to the inner flange and ribbed underside of insulation

• Non-continuous thermal break plate

Inner Leaf: 100 - 115mm
