Roof insulation à Machelen
Insulation of pitched roofs and lofts, from the inside or as sarking. Machelen and Diegem call for two ways of working a few streets apart: single-family houses where the occupants are at home, and company buildings where the work cannot stop.
5 km from our depot in Grimbergen
What that changes here
On the periphery a lot of owners insulate the roof themselves, and that is where we find the most damage: insulation pushed up against the roofing underlay, no air gap at all, a vapour barrier full of gaps. We put the ventilation right first, the insulation after.
Machelen and Diegem form a mixed fabric of residential districts and industrial estates. We work there on single-family houses as much as on warehouses and company flat roofs, with the organisation that goes with it: working outside opening hours and zone by zone.
What we get called out for in Machelen
Machelen and Diegem call for two ways of working a few streets apart: single-family houses where the occupants are at home, and company buildings where the work cannot stop. For the latter we plan zone by zone and outside opening hours; for the former, as anywhere else.
Machelen porte le code postal 1830 et se situe in the northern periphery of Brussels. Notre équipe part de Grimbergen, à 5 km : nous y planifions l’isolation de toiture en même temps que les chantiers de Vilvoorde, Zaventem et Grimbergen, pour qu’un déplacement serve plusieurs toitures.

Pour un devis, la visite à Machelen se fixe en général sous quelques jours ouvrés. Nous partons de Grimbergen, à 5 km, et nous groupons nos visites par secteur : si un chantier tourne déjà cette semaine à Vilvoorde ou Zaventem, 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.
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.
The Flemish and Brussels grants change every year and depend on your situation, the dwelling and the contractor. We supply the invoices and technical data sheets required; the application is made to the relevant body. We do not quote amounts that will no longer be valid in six months.
