What type of lintel for internal cavity wall with opening.

[LSB]

 

Hello

We have a block / block wall that will be mostly internal.

The only external bit is above the hall roof until it gets to the barn roof.

In this wall there is a doorway from the hall to the kitchen

 

Originally this wall wasn't going to be, it was a steel above and open from the hall to the kitchen.

But, due to various situations it is now a wall.

It is a cavity wall as part of it will be external and supporting the main roof.

 

When I spoke to the SE he just said, it will need a lintel !

Well I know that 😄

But, he wasn't forthcoming with the lintel design and now appears to be ghosting me on this and other questions.

 

I need to order this lintel so we can progress.

 

 

 

 

 

All the other lintels we have are thermally broken (block / block not brick) with DPC cover and weep vents

 

 

To me this doesn't seem right for my current opening.

The gap is 1370 and will not have a door.

the insulation will obviously not be in the opening, unlike the diagram, that is the rest of the wall.

 

Please can someone advise what we need here

The hall roof is 2 blocks above the opening and the main roof 4 blocks.

It certainly doesn't need weep vents at the lintel level as they would be inside the rooms, these will be higher up where the roofs are.

 

TIA

Jill

I think you need a spec for the lintel, either from your SE or the lintel manufacturer.  Cavity wall lintels are designed to take more loading on the inner leaf and any loads spread along the length.

Thanks, the SE is a total waste of space, he takes weeks to respond to anything.

But, I'll talk to the linter supplier, good idea.

Two concrete lintels.

If you do not want the lintel to show on outside brickwork  then you use  a "catnic" lintel  and  conctrete one for inside

there are many suppliers but this will show you how they fit and work

Where the opening is both walls are 'inside', this is primarily an internal wall except for the top 2 blocks when the inside of the hall becomes an external wall.

your picture shows brick work 

is this covered with cladding ?

if so then 2 concrete ones will do as the edge of them will not be seen 

 or if totally internal then concrete will do

it's actually block / block, but I couldn't find a picture online showing that.

So, they will both be covered by plasterboard
