Blocking up rear external door

Question

Advice please how to block up a rear back garden door.

Is it ok to brick up the outside and inside do a timber frame with plasterboard ? Will add insulation.

Does this comply with Building Regulations ?

Thanks

Yes you will need building regulations so contact your local council planning team.

If the existing outer skin is brick you should match it and tooth the bricks. Take care to ensure a good mortar bond between old and new brick.

The inner skin can be block tied to the existing with starter bars. Use cavity batts or rockwool.

Tie the inner skin to outer skin with wall ties every second block course with 2 ties, starting at DPC to stop cavity batts falling into cavity below DPC.

DPC on both inner and outer skins tied into existing DPC by way of groves cut out with a grinder(minimum 9”).

Internal finish can be whatever you choose.

If you plan to do it yourself then there is a good video on YouTube HOW TO BRICK UP A DOOR CORRECTLY . PT 2Visit

Hi you need to breeze block the inside with insulation between the exterior & interior walls

Tony · Answer

You need to inter lock out side brick work then insulate wall inside then stud work and plaster board on the inside

Dave · Answer

You will need to follow the existing damp course on the external brickwork (which should be a minimum of 150mm or 6 inches above ground level)
Inset 80mm-100mm of celotex insulation to the timber framework and plasterboard over

If it’s a cavity wall construction the block work at the back will need to have a DPC tray installed to carry on running through the fabric of the building.

This still needs to be the same process if its a timber shell building with a brick outer shell construction. In this case the DPC would be stapled on the stud at 230mm above the existing DPC to again form a tray.

I hope this helps

To be quite honest I would only recommend this if its a temporary and to be honest you will need to use a external waxed board 
I WOULD DO IT TRADITIONALLY USE BRICK A CAVITY AND INTERNAL BLOCK KEYING THE BRICK PROPERLY IT SHOULD NOT BE MUCH MORE EXPENSIVE.

Vernon · Answer

Yes but I would do internal useing blocks. A better job and you won’t get condensation

Stuart · Answer

Absolutely it is.. insulation needed on the inside but aslong as the brickwork is sound there’s no issue..

Hello this would be ok with building inspectors but you must make sure the cavity is correct
