Roof insulation
in Rixensart
Roof insulation of the loft, the loft floor and the roof slopes, with a continuous vapour barrier and the ventilation kept open. In Rixensart (1330) this comes up regularly: being close to the woods keeps everything damp, so moss removal and gutter clearing come round more often here than elsewhere.
The context in Rixensart
Why here in particular
Between its castle, its woods and its residential streets, Rixensart has a varied building stock where the old sits alongside 1970s builds. In practice, being close to the woods keeps everything damp: moss removal and gutter clearing come round more often here than elsewhere.
In Belgium, 25 to 30 % of the heat lost from an uninsulated house goes out through the roof. But roof insulation fitted without a continuous vapour barrier and without an air gap simply moves the problem: the vapour condenses in the wool and the roof timbers take in water.

How it runs
How the job runs
The same protocol everywhere, adapted to what the visit reveals on site. Nothing is decided from the pavement.
- Survey and calculation of the thicknesses
- Mineral wool or cellulose insulation
- Continuous vapour barrier and tapes
- Treatment of penetrations and openings
- Keeping the air gap
- Removal of offcuts
Site assessment
Available thicknesses, roofing underlay present or not, existing ventilation.
Preliminary treatment
Sound roof timbers before insulating. We never cover over attacked timber.
Fitting the insulation
Mineral wool between and under the rafters, or blown onto the loft floor.
Vapour barrier
Continuous membrane, overlapping strips, tape on every penetration.
Ventilation
Air gap kept under roof covering. That is what prevents condensation.
Frequently asked questions
Roof insulation in Rixensart
The questions we get asked most often before this kind of job.
And without roofing underlay?
There needs to be a ventilated air gap under the roof covering, or you fit an underlay. Without it, the insulation takes on water the first winter.
Are there any grants?
Depending on the Region and the period, yes, often tied to a minimum thickness and a registered installer. We tell you where to check rather than promising you an amount.
Cellulose or wool?
Blown cellulose for an uneven loft floor, board wool for a slope between rafters. Thermal lag is what counts in summer.
Do you come out to Rixensart with no extra call-out charge?
Yes. Rixensart is one of our 17 municipalities: the call-out is included in the quote, not added at the bottom of the invoice.
