2. Building insulation - Wikipedia

   en.wikipedia.org/wiki/Building_insulation

   To determine whether you should add insulation, you first need to find out how much insulation you already have in your home and where. A qualified home energy auditor will include an insulation check as a routine part of a whole-house energy audit. [15] However, you can sometimes perform a self-assessment in certain areas of the home, such as ...

3. Thermal transmittance - Wikipedia

   en.wikipedia.org/wiki/Thermal_transmittance

   The average thermal insulance of the "bridged" layer depends upon the fraction of the area taken up by the mortar in comparison with the fraction of the area taken up by the light concrete blocks. To calculate thermal transmittance when there are "bridging" mortar joints it is necessary to calculate two quantities, known as R max and R min.

4. Concrete slab - Wikipedia

   en.wikipedia.org/wiki/Concrete_slab

   Without insulation, concrete slabs cast directly on the ground can cause a significant amount of extraneous energy transfer by conduction, resulting in either lost heat or unwanted heat. In modern construction, concrete slabs are usually cast above a layer of insulation such as expanded polystyrene , and the slab may contain underfloor heating ...

5. Building insulation material - Wikipedia

   en.wikipedia.org/wiki/Building_insulation_material

   It can be used as internal insulation : between studs, joists or ceiling rafters, under timber floors to reduce sound transmittance, against masonry walls or externally : using a rain screen cladding or roofing, or directly plastered/rendered, [24] over timber rafters or studs or masonry structures as external insulation to reduce thermal ...

6. Lift slab construction - Wikipedia

   en.wikipedia.org/wiki/Lift_slab_construction

   Lift slab construction (also called the Youtz-Slick Method) is a method of constructing concrete buildings by casting the floor or roof slab on top of the previous slab and then raising (jacking) the slab up with hydraulic jacks. This method of construction allows for a large portion of the work to be completed at ground level, negating the ...

7. Insulating concrete form - Wikipedia

   en.wikipedia.org/wiki/Insulating_concrete_form

   Like other concrete formwork, the forms are filled with concrete in 1-foot to 4-foot high "lifts" to manage the concrete pressure and reduce the risk of blowouts. After the concrete has cured, the forms are left in place permanently to provide a variety of benefits, depending on materials used: Thermal insulation; Soundproofing
