We are renovating an old Bressan house in Bresse. It was built with half-timbered and rammed earth. Is it possible to make an exterior insulation on adobe walls? The rammed earth is a perspiring material, what can be put as insulation?

Rammed earth walls and wood sides can be very durable, provided do not change their hygrometric equilibrium. Insulating a rammed earth wall can make it lose its basic qualities: inertia, phase shift, and even more accelerate its degradation. If the wall really needs to be isolated, focus oninsulation from the inside, on the basis of counter-partitions or doublings separated from the load-bearing wall, by installing high and low ventilations at regular intervals.

How to insulate a rammed wall from the outside?

FAQ - 💬

❓ Can you insulate exterior walls from the outside?

👉 Using dense-pack insulation techniques, empty cavity and some partially insulated cavity frame walls can be insulated from the top and bottom or from the interior or exterior.

❓ What is the best insulation for outside walls?

👉 Spray Foam Insulation Open cell spray foam is usually what is recommended for residential projects. The foam expands and completely fills the cavity. Closed cell foam can be used but is better suited for exposed walls as it is more durable.

❓ How do you build an insulated exterior wall?

👉 To add insulation to any exterior wall, holes are drilled between the studs of the existing walls. Then, spray foam, cellulose, or another form of loose-fill insulation can be blown in to fill up the wall cavities. Finally, the holes must be plugged up and refinished to match the rest of the wall.

❓ How do you insulate a cold wall from the inside?

👉 To insulate a cold wall from the inside, you'll need to get measuring and installation equipment, measure your wall, and order wood studs and insulation batts accordingly. Once you have the materials, you'll frame your wall with wood studs and tuck in insulation batts between the studs.

❓ Is it better to insulate walls from outside or inside?

❓ How do you insulate an older house from the outside?

👉 One way to insulate walls of an old house is to focus on the home's exterior:

  1. Apply a house wrap/vapor barrier to exterior walls.
  2. Attach 1-inch foam board insulation.
  3. Install siding over the insulation.
  4. Replace old windows with energy-efficient units.
  5. Caulk window trim and use weatherstripping to reduce air leaks.

❓ Do you need a vapor barrier on exterior walls?

👉 Because it is mostly hot and very humid outside the building, the vapor barrier should be installed on the exterior of the insulation. This is recommended to keep the outside moisture from getting into the less humid, cooler interiors and damaging the building's structure.

❓ How thick should external wall insulation be?

👉 between 50 and 100mmThe thickness of the insulation needs to be between 50 and 100mm and is usually installed where there are severe heating problems or the exterior of the building requires some form of other repair work providing the opportunity of adding insulation.

❓ Is external wall insulation any good?

👉 A poorly insulated house often leads to air leakage, which can cause around 20% of energy loss in older homes. External wall insulation can reduce heat loss and improve airtightness by helping to seal off cracks and holes in the wall.

❓ How can I insulate my walls cheaply?

👉 6 Inexpensive Insulating Materials For Interior Walls

  1. Radiant Barrier.
  2. Stone Wool.
