Roof insulation à Schaerbeek
Insulation of pitched roofs and lofts, from the inside or as sarking. In Schaerbeek nine calls out of ten are about water coming in through the cornice.
7 km from our depot in Grimbergen
What that changes here
The Brussels loft is narrow, tall and awkward to get to; everything goes up by hand through the stairwell. In a subdivided building there is also the question of who pays for what. Technically we watch above all the airtightness around the dormer and the junction against the party wall: those are the two places where damp comes back.
Schaerbeek is the municipality of the 1890-1910 town house: tall, narrow facades, ornate cornices, mansard roofs in slate and a box gutter that disappears entirely behind the cornice. Around Josaphat Park and in Terdelt the 1930s are added to that, and their concrete tiles are now reaching the end of their life.
What we get called out for in Schaerbeek
In Schaerbeek nine calls out of ten are about water coming in through the cornice. The town houses there have a box gutter running from wall to wall, often still in lead or in zinc with no expansion joint, with a timber deck underneath quietly rotting. The second most common request is the lower slope of the mansard: slates working loose one after another.
Schaerbeek porte le code postal 1030 et se situe in the Brussels-Capital Region. Notre équipe part de Grimbergen, à 7 km : nous y planifions l’isolation de toiture en même temps que les chantiers de Evere, Brussels et Molenbeek-Saint-Jean, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Schaerbeek se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 7 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Evere ou Brussels, cela peut aller plus vite. En cas de fuite active, nous venons d’abord bâcher et sécuriser ; l’isolation de toiture n’est chiffrée qu’ensuite.
For a pitched roof, aim for 18 to 24 cm of mineral wool or PIR depending on the material, to meet the requirements in force. In an existing roof structure the space between rafters is limited: you then add a second layer under the rafters, crossing the joints.
In most cases, yes: the insulation is fitted from the inside. Sarking — insulation laid over the roof structure, under the tiles — is only justified if the roof has to be redone anyway. In that case it is the best solution, and the question comes up before the tiles are ordered.
