Foilboard Floor Saddles

Foilboard Floor Saddles are used when installing Foilboard before the flooring is laid. Fixed under the floor joists, Foilboard Floor Saddles greatly improve the thermal performance of the floor and make underfloor joist insulation easy. Simply place the saddle over the floor joist and fasten with a nail or staple. Then slip the Foilboard® between the floor joists and clip into place.

Foilboard Floor Saddles for Foil Underfloor insulation

Foilboard Australia Pty Ltd manufactures a range of fixing accessories tailored to suit many construction applications. These Foilboard timber fasteners ensure that the material will be installed correctly and maintain its thermal performance for the life of the application. Whether it is for timber or steel frame construction, underfloor applications and even commercial systems, Foilboard® has the right fixings to suit all applications.

Installation suggestions for Underfloor Foilboard

Insulation panel and Floor Saddles is best done after joists are fixed to bearers and before yellow tongue or strip flooring is laid down. It is recommended that for best-fit plumbing rough in and all other services under floor are complete. Foilboard Insulation Panel is lightweight, easy and safe to handle. It may be easily cut to size with a long snap blade knife. Off-cuts can be taped and re-used.

Space Foilboard Floor Saddles on top of floor joists at approximately 600mm centres. Saddles should be spaced 200mm from end of sheet. At double joists simply cut the Foilboard Floor Saddles in half and fasten with a nail. Push Floor Saddles down so that the specially designed teeth can grip the joist. Cut Foilboard under insulation panel to size to fit in-between joists. Place sheet between joists, resting on the lip of the Floor Saddles. Gently apply pressure to the Foilboard Insulation Panel until it clicks into place with our patented lock-in flap design. This will prevent wind and vermin from unsettling the sheet from underneath. For a perfect job sheets should be taped where they join. Tape or silicone gaps and holes to prevent air infiltration that lowers the ‘R’ value.

Method of Calculating Quantities of Foilboard

  • Measure Floor or Wall area.
  • Add 5% to area to allow for cutting and waste, deduct window and door openings.
  • If using 2.44m sheets divide the area by 2.93 to give the number of sheets required.
  • If using 2.70m sheets divide the area by 3.24 to give the number of sheets required.
  • Round up to the next full sheet.
  • Floor saddles should be on joists at approx 600mm centres and spaced at 200mm from sheet ends.
  • For retro-fits Foilboard should span across the underside of joists and between bearers using three Foilboard fasteners per joist. Joins do not need to be made on a joist and you should tape all joins.
  • Generally 1 bag of saddles is required for every 45-50m2 and 1 Role of Green Tape will be required for every 100m2. For retro-fits you will generally require 1 bag of Foilboard Fasteners and 1 roll of Green Tape for every 15-20 sheets, for Aluminium tape you will require one roll for every 10-12  sheets approx. Flexifastners should be used for all sheets 25mm or thicker and you will require 1 bag of 200 fastners for every 15-20 sheets. Or for sheets over 25mm in thickness you can order the plastic plates and supply your own fixing nails or screws. Spacers for brick work you will require 8-10 spacers per m2
