The main part of our house is made of stone, but we have a back addition which was added much later (about 30 years ago) that is made of bricks. Unfortunately, this was not a very good period for construction and we really pondered if we should tear it down and rebuild or renovate.

In the end, and after discussions with a few local professionals, we decided to renovate. One of the last parts of the renovation was adding insulation to the walls. In our mid-continental climate, insulation is applied on the outside of the wall. And typically in Hungary such insulation is Styrofoam. Below are some photos of the process of adding this external insulation.

From left to right: normal red brick, old insulating brick, and modern insulating brick.

From left to right: normal red brick, old insulating brick, and modern insulating brick. Our wall was made up of the first two bricks, providing only minimum insulation.

Because of the bricks that made up our wall, we decided to go with an 8 cm (3.15 inch) thick insulation layer.

Styrofoam fasteners

The Styrofoam is stuck onto the wall with some thin plaster, then fastened securely with plastic pins drilled through the Styrofoam and into the wall.

Wall before Styrofoam.

Wall before Styrofoam. Some added plaster was applied to make the wall straight enough to apply the Styrofoam.

Base Plaster Coat

A plastic net was applied to the Styrofoam and a plaster under coat was applied. The final plaster coat with a special external “colored” plaster will be applied in the fall.

Plaster Undercoat Applied

And again the same view with the protective plastic netting and base coat plaster applied.
