To calculate the U-Values for any Block cavity wall
construction you need to select the Outer Leaf material with the
Brown selector near the top of screen choosing from Brick, Concrete
Block or 3 variants of Insulating Blocks, next you select from
either Full cavity fill bats or Partial fill with clear 50 mm
cavity and either Phenolic or Polystyrene type boards which are
fitted to the cavity side of the Innerleaf. The thickness of the
insulation is chosen with the Green selector at the bottom of
screen and the Innerleaf Block type and thickness with the Brown
selectors on right of the display, the Internal wall finish is
12.5 mm plasterboard on dabs. The result is given in the Box
at the bottom centre of your screen. The Full Fill bats are Mineral
Wool with a Thermal Conductivity of 0.038 W/m.K, Phenolic boards
are 'Kingspan' or 'Celotex' type Rigid with a Thermal Conductivity
of 0.023 W/m.K and the Polystyrene has a value of 0.040 W/m.K
To calculate the U-Values for your Timber Framed and
Masonry cavity wall you can choose from Mineral Wool, Polystyrene or Phenolic
Insulation with the Green selector at the top of
your screen, next comes the OuterLeaf of your wall selecting from
Brick, Concrete Block or Lightweight Insulation Blocks with the
Brown selector near the top of the display, next you choose your
stud centres with the Brown selector near the bottom right of
the screen, lastly you select your insulation thickness with the
Green selector along the bottom of the screen. The result is given
in the box at the bottom centre of the screen. The internal wall
finish is 12.5mm plasterboard and 12mm ply on the cavity side of the studs
Phenolic Insulation is of the 'Kingspan' or 'Celotex' type Rigid boards
with a Thermal Conductivity of 0.023 W/m.K whereas the expanded
Polystyrene has a value of 0.040 W/m.K
To calculate the U-Values for your Floor you enter your
Floor dimensions in the 2 boxes provided in top half of screen,
The Perimeter in the top box and the Area in the box just below,
The Perimeter in meters is the distance all around your floor
as indicated by the blue line, the Area is the Length multiplied by
the Width to give Sqr Meters. You then select the type and thickness
of insulation with the Green selectors at the bottom of your screen,
The result is given in the box at the bottom centre of your screen.
If you use Insulation Blocks below the DPC on the Inner Leaf then
no edge insulation is required for the floor slab otherwise a Minimum
of 30mm Phenolic insulation will be needed, Phenolic Insulation is of
the 'Kingspan' or 'Celotex' type Rigid boards with a Thermal Conductivity
of 0.023 W/m.K whereas the expanded Polystyrene has a value
of 0.040 W/m.K
