  1. I am about to install French doors 1.3m wide x 2.0m high. I was going to use a 1.5m 75mm thick concrete lintel to place above doors the house is an old terrace house 3 floors high with roof. Is this concrete lintel sufficient or do I need a thicker lintel ?

      Hi Ben, thanks for leaving a comment.
      Please don’t use a Catnic! I would suggest a beam, but I will get the technical team to come back to you.
      Thanks.

  3. I am knocking two rooms into one to make a kitchen diner, the beam required would be supporting first floor joists and the plaster board wall between bathroom and a bedroom. Please advise as what beam to use.

  4. I am planning to extend across the whole of the back of a standard 1935 semi detached 3 bedroom house. The open span would be approximately 5 meters. Can this be achieved without a central support?

  5. Hello,
    I am creating a 1800mm wide opening in a single block interior wall which will be 1900mm high. The building is a bungalow with a bedroom above in the roof space. I would like to use a concrete lintel but I’m not sure of the thickness I will need 65mm or 140mm. Can you please advise me on this?
    Best Regards,
    John

  7. Hi,
    The structural engineer specify a UC lintel.
    However I can’t find a local supplier – I believe the Dim for that is 100 x 100 mm. ( I can be wrong)
    I would think a U2 would do – 150 x 100 mm
    Please advice

    Regards

  9. Hi,

    I’m looking to create an opening of up to 3,0 meters for a folding sliding door or similar, can I simply use a Catnic style lintel at 3,6 meters long?

    The house type is a semi-detached townhouse (3 storeys), there’s approximately 23m² of brick and block work (minus 4x windows) above and so the lintel will be installed on a load bearing wall but not taking loading from joists.

    Thanks in advance!

  12. Hi I am installing a new set of french doors 1400 wide in the external wall of a victorian terrace house.
    The wall is double thickness solid brick and the wall above to rafters is approximately 3m
    The roof is a standard terrace house pitch with concrete tiles loading the rafters onto the wall above the french doors
    I am thinking of using standard prestressed concrete lintels of 1800mm width (nearest size up) – 2 of them side by side
    Is this the best way to go?

    Also I am removing 1.6 meters of the internal wall between the lounge and kitchen and need to install a lintel/steel above to support the brick wall above and the bedroom ceiling rafters and the kitchen/loungs floor joists – this seems to be too big a span for a concrete lintel – well cetainly one that will fit in a single skin brick wall – so using a steel how do I calculate the size of the steel required please.

    Regards

  13. I am looking at removing a 12FT wall which is load bearing located downstairs and it appears to hold the joices upstairs also but not the celing.

    House is 1974 build 4 bed detached.

    Looking at having the opening as wide as possible could you let me know the beam that would provide this current thickness of the wall is 9CM in total width.

  14. Hi

    I’m looking to make 2 rooms into 1 (kitchen and dining room). The wall is a supporting wall for joists upstairs floor and is brick all the way up to the attic. I will need between a 2500 and 2700 long beam to span including the 150mm each end. But which beam would I use.

    Thanks

  15. I am moving house soon and am wanting to knock down a wall between the living room and dining room and move the wall back around 3ft, the wall is a load bearing wall and I am eventually looking to add a bedroom into the attic and need to know if that will effect the lintel I will need.

    would I need a specialist lintel or would a concrete linted bear the load?
