How to measure thermal insulation

When installing kraft paper faced insulation you will encounter blocks and long rolls. The blocks are pre-cut to fit into standard 2.60 m high wall cavities. Thus, roll insulation is best for floors, ceilings and roofs with long joists or joist bays and for tall walls.

Kraft faced insulation can also be friction fit into friction fit cavities in the structure, between studs and cannot be stapled in place, if allowed by local building code.

For this reason, faced insulation is typically installed on the warm wall side in winter. In other words, the sheathing must face into the living space, or into the attic or basement or into the room.

Because the siding serves as its own vapor barrier that traps moisture inside a building, it should not be used with additional vapor barriers. In fact, it is an excellent solution to potential condensation.

How to insulate the floor from humidity

Do you have cold feet inside your home because it does not have thermal insulation in the floor, today we look at how to provide thermal insulation to the floor of your home, exploring options for both an old wooden floor slab and a current ceramic slab, we show how to insulate under the floor or above the floor slab, while minimizing thermal bridges.

In general, floor slabs are very solid, concrete slabs, joist-and-vault ceramic floor slabs, etc., in addition to the traditional timber beam floor slabs in many buildings in city centers and in renovation works.  When uninsulated, these two floors will have a thermal insulation U-value of between 0.45W/m2K and 0.70W/m2K, but this depends on the floor geometry and the amount of thermal bridging.  In each case, the target U-value of thermal insulation after installation of thermal insulation is between 0.20W/m2K and 0.25W/m2K (depending on the floor geometry).

Floor insulation materials

Building floors are thermal magnets and sound speakers. This can cause long-term problems for both tenants and owners, either in the form of disturbing noise, high energy bills or much colder living conditions.

To find out how much insulation you will need, first measure the length and width of the floor and calculate the value of the area in m². You may prefer to order a slightly higher amount to avoid coming up short.

How to insulate the cold floor

To prepare Acoustiblok for installation, place the roll on an Acoustiblok RD350 roll dispenser. An “A-Base” can be improvised from scrap wood and pipe [ Fig. 3 ], but the RD350 dispenser is the safest and most reliable way to deploy Acoustiblok. Unroll the first few feet of the roll [ Fig. 4 ] and cut off the excess material at the end with a square and knife. [Fig. 5 ] Use the square when cutting the Acoustiblok pieces to make the installation. [Fig. 6 ] This gives you a level starting point for the next installation, and allows for tighter joints and a more level installation. Roll the cut piece in the opposite direction it came off the main roll to minimize curling of the material as you install it [ Fig. 7 ].

Steel stud wall installationInstalling Acoustiblok on steel studs is the same process as installing wood studs, with a few variations. You must of course use threaded screws, with brass caps, washers, or similar to prevent the material from breaking under its own weight. Metal caps and tapping screws (Acoustiblok Item # WHS) are available from Acoustiblok Inc.
