In Great Britain too, the post-war economic development resulted in a sudden demand for popular housing close to the large factories. Entire popular residential districts were planned and made with the aim of providing inexpensive housing; this was the context of development of a district on the outskirts of a city in Scotland where an important recovery plan has recently been carried out.
The vertical structures of about 200 buildings that make up the district, composed mostly of single-layer walls of local stone material, were seriously decayed and covered on the inside with thick layers of mould that made the homes unhealthy and uninhabitable.
The plan for the recovery of the district therefore included, besides internal restoration work and the repair of the systems, also the reclamation of the perimeter walls with a cladding of insulation in order to guarantee both a correct management of the thermohygrometric conditions of the environments and the respect of the strict technical regulations for energy saving in the building industry.
The heat insulation of the buildings was carried out from the outside according to the traditional "cladding" technique. Stiferite panels of Polyiso foam Class S, inserted in a special plastic section at the base of the walls, were anchored to the structure with mechanical fixtures. On top of the insulating layer a fibreglass mesh for plastering over was applied on which the first coat was spread, consisting of 4 mm of cement mix with particular elasticity features.  
For the top coat of plaster a marble grit mix was used, 10 mm thick, in two different shades of pink beige to highlight a kind of podium of the buildings.
As well as better energy performance, Stiferite Polyiso foams also ensure excellent dimensional stability and optimum resistance to thermal shocks which are very frequent in continental climates. The saturated fibreglass coating of the panels also offers a particularly suitable support for the adhesion of the elastic cement mix which plays a fundamental role in ensuring the correct interaction of the different stresses in the layers that make up the cladding.
