Loose Fill Insulation Klarvatten

Blown-in insulation for Klarvatten attics and closed cavities

Blown-in material fills the awkward parts of an Klarvatten building that batts leave gapped — around cross-bracing, over the top plates of interior walls, into the shallow triangle at the eaves. It settles over time, which is why it is specified at a settled depth rather than the depth it looks on the day. Air sealing comes first, because loose material laid over an open ceiling penetration hides the leak instead of stopping it.

• Depth read back at the corners, not just where the hatch is
• Existing material assessed — topped up, or removed if it is wet or contaminated
• Ceiling penetrations air-sealed first, not buried
• Baffles at the eaves so soffit venting stays clear
• Settled depth specified and marked before the hose starts
• Even coverage carried right out over the top plates

Loose Fill Insulation Klarvatten: your questions answered

What about my pot lights?

Older recessed fixtures are not all rated to be covered and loose-fill packs right against them. We check the rating, and where they are not rated they get a proper clearance detail that is also sealed, rather than being buried and hoped about.

How do I know I got what I paid for?

Bag count. Every bag states the area it covers at a given depth, so bags used divided by area is exactly what went in. We keep them, mark the target settled depth, and read the depth back at the corners rather than the middle.

What do I get when the job is done?

The bag count, the target settled depth, and photographs of the finished space including the corners and the eaves — so you can confirm years later what was actually installed instead of probing a hole and guessing.

Can you just add over what is already up there?

Usually, and it is the best value if the existing material is dry, even and uncontaminated. If it is damp, matted, rodent-affected or hiding unsealed penetrations, adding over it buries the problem — we tell you which one we found.

Is it too heavy for my ceiling?

Rarely, but worth thinking about on an older lath ceiling or a long unsupported span. Where the ceiling is old or already sagging we would rather use the lighter material at a sensible depth, and sometimes recommend fixing the ceiling first.

Is blown-in better than batts?

In an attic, usually yes, because it flows around trusses, bracing and wiring where batts get cut short or forced and leave gaps. In open framed walls at regular spacing, batts are fine. We recommend by the space, not by what is on the truck.
