TF70 Thermafloor insulation for use in garage conversion
floors
PREMIUM PERFORMANCE
For the insulation of suspended timber floors we recommend
the use of either Kingspan Thermafloor TF70 zero ODP
(high performance CFC/HCFC–free rigid urethane
insulation) or Kingspan Kooltherm® K3 Floorboard
(premium performance CFC/HCFC–free rigid phenolic
insulation). The boards are easily cut to fit between
the joists at any centres.

|
For specific project U–value calculations please
call the Kingspan Insulation Technical Services Department.
The l-value quoted is based on the procedures for the
determination of the aged values of thermal resistance
and thermal conductivity, laid down by the harmonised
European standard BS EN 13165, using so called 90/90
principles. Comparison with alternative products may
not be appropriate unless the same procedures have been
followed.
Fixing details
The insulation should be installed between the floor
joists prior to the installation of the floorboards.
Cut boards to snugly fit joist spacing and support using
either timber battens, proprietary galvanised steel
saddle clips or galvanised nails partially driven into
the side of the joists. Battens/nails should be placed
at an appropriate height to suit the thickness of board
being employed and nails should remain 40 mm proud of
the joist.
Lay the boards between the joists so they are supported
by the battens/nails.
Insulate any narrow gaps between a joist and the perimeter
wall with specially cut pieces of board. Support these
on blocks nailed to the underside of the joists.
Boards may be cut using a sharp knife or fine-toothed
saw.
SOLID FLOORS
For solid floating ground floors we recommend the use
of Kingspan Thermafloor TF73 zero ODP composite floor
insulation. A separate vapour control layer is not required
and the boards promote quick response heating.
Achieving “U” values
The table below details typical thickness of Kingspan
Thermafloor TF73 zero ODP required to achieve the various
U–values to satisfy Building Regulations/Standards.
Product Thickness = insulation thickness + 18 mm chipboard.
The ?–value quoted is based on the procedures
for the determination of the aged values of thermal
resistance and thermal conductivity, laid down by the
harmonised European standard BS EN 13164, using so called
90/90 principles. Comparison with alternative products
may not be appropriate unless the same procedures have
been followed.
For the purposes of these calculations using the method
as detailed in BS EN ISO 13370: 1998, the soil has been
assumed to be clay or silt, the wall insulation is assumed
to overlap the floor insulation by 200 mm minimum and
the standard of workmanship has been assumed good and
the correction factor for air gaps ignored.
Insulant thickness only, does not include chipboard.
Fixing details
Ensure floor surface is smooth and flat. Sand blinding
may be used to achieve this.
Lay boards in a “brick pattern” and glue
the chipboard using joints PVA adhesive applied to the
top and bottom of the tongue and groove.
Insert wedges between the wall and floor to maintain
tight joints whilst the adhesive sets. Replace the wedges
with Kingspan Styrozone® to act as a compressible
filler.
An allowance of 10 mm or 2 mm per metre run of floor,
whichever greater, should be left against all walls
and abutments. Over a large run of floor, intermediate
expansion gaps may be required (please contact the Kingspan
Insulation Technical Services Department for further
details).
Ensure the building is weather tight before fixing floors
incorporating this product.
Cutting should be carried out using a fine-toothed
saw
