Fitting R'BULL insulation in a living room

The room where you do not move

A living room is the only room where you sit for hours at a time. It is therefore the one where discomfort is most noticed, and where the temperature of the surfaces counts for more than the temperature of the air.

The cold ceiling you do not see coming

A surface colder than the room absorbs the body's radiation. A poorly insulated ceiling thus produces a permanent feeling of coolness, even with a thermometer reading twenty degrees, and that feeling is corrected by insulation, not by the thermostat.

What the reflector changes

By closing the plenum, it raises the surface temperature of the finished ceiling. The difference between skin and surface falls, the radiant exchange reduces, and comfort rises without consuming more.

A job that stays light

Fitting takes a day in an ordinary room, with no wet phase and no drying. The living room is usable the same evening, which counts for a room the family occupies every day.

What is gained in height

Thirteen millimetres of insulation plus the air gap needed, against several tens of centimetres for traditional insulation of comparable performance. In a room two metres fifty high, that difference often decides feasibility.

The effect in summer

If the living room is under a loft or a roof, the same product slows the heat coming down in the afternoon. It is a secondary benefit in winter, and a main one in July. A living room under a sloping roof then gains several degrees in the late afternoon, the moment when the roof gives back the heat stored since midday.

The product is presented on its data sheet, and its properties on the R'BULL properties page.
