External wall insulation vs removing render and internal insulation
Anonymous user 03/03/2024 - 3.06 PM
Hi, we have damp in our house as the render (approx 150m2) is shot and leaking so have been looking at external wall insulation (very costly) vs removing the render and internally insulating. Pros and cons?
Are you a tradesperson and able to answer this question?

Hello,
I have listed below some pros and cons to internal wall insulation vs external wall insulation. You will also need to take into account that if you are thinking of doing internal wall insulation in your kitchen that your current fixtures and fitting will not fit back as your floor space will be reduced.
Internal wall insulation:
- Will slightly reduce the floor area of any rooms in which it is applied (the thickness of the insulation is around 100mm)
- Is disruptive, but can be done room by room
- Requires skirting boards, door frames and external fittings to be removed and reattached
- Can make it hard to fix heavy items to inside walls – although special fixings are available
- Needs any problems with penetrating or rising damp to be fixed first.
External wall insulation:
- Can be applied without disruption to the household
- Does not reduce the floor area of your home
- Renews the appearance of outer walls
- Improves weatherproofing and sound resistance.
-Fills cracks and gaps in the brickwork, which will reduce draughts
-Increases the life of your walls by protecting the brickwork
-Reduces condensation on internal walls and can help prevent damp (but will not solve rising or penetration damp)
-Requires good access to the outer walls
- Is not recommended if the outer walls are structurally unsound and cannot be repaired.
