Foil-Tec Double is commonly used in conjunction with underfloor heating, to secure the insulation in place we advise using the YBS Saddle Clips as these will hold the material into place, whilst creating an air cavity that enables the Foil to reflect and perform.

How to Install Foil-Tec Single/Double on Floors
-
Roll out Foil-Tec
Start by rolling out Foil-Tec over the joists. It is recommend to roll the insulation perpendicular to the joists. Avoid cutting the length just yet, as the recess will use up extra material.
-
Create a recess with Saddle Clips
Saddle Clips are important for keeping the insulation fixed in place, but additionally to create an even air cavity. Install Saddle Clips over the joists, which fits Foil-Tec snug around the timber. We recommend 4 saddle clips per m2
-
Alternate method - using Staples
An alternate method if you wish to avoid Saddle Clips is to staple. Staple Foil-Tec down the joists, to create an air cavity. Tip - the further down the joists, the greater the thermal benefits! This is because an increased cavity will give an improved R-value.
-
Overlapping Foil-Tec
Overlap Foil-Tec by a min 50mm, however to a max of 100mm. This prevents any draughts. Ensure any overlaps are left un-taped. This allows any potential moisture build-up to properly escape.
-
Ensure Foil Tec is lipped up the walls
Around the perimeter, it is important to lip Foil Tec up the wall. It needs to be taken up by a min of 50mm. This will generally be then hidden by chipboard and skirting board. This is to prevent any draughts. Follow with Thermaseal Foil Tape around the perimeter.
-
Finish by installing Chipboard
Once all the insulation is fixed down and recessed, you are now ready to install your finished floorboards.
