If you are looking for an insulated shop door or to insulate an existing Diamond Door, our EPS (expanded polystyrene) ridged board panels are a great option. Your door has the potential for a large amount energy loss, so investing in a good quality insulated door is beneficial for you in the long run.

When deciding which door to purchase or the insulation options for your existing door, consider the investment and return over time. Will the option you choose loose energy over the years and offset the inexpensive cost upfront? Will the investment you make in your door end up saving you money in the long run?

The Diamond Doors insulation panels are:
  • Attached to the exterior door frame, creating a full thermal break.
  • Wrapped with a white aluminum embossed liner for the interior aesthetic. Different liner colours and styles are available for special order.
  • Pre-cut to fit the door in factory for easy installation onsite.
  • Consistent R value (ability of an insulating material to resist heat flow) at R12 and R16.
  • Does not retain moisture.
  • Price is between $2.50 - $3.25 CAD per sq/ft.
Additionally, a neoprene foam for the perimeter of the door is included. All our doors are equipped with top and bottom weather seals to create a complete barrier from the natural elements.

Spray foam is a common alternative to using a polycarbonate panel. However, there are some things to consider before choosing this option for your bi-fold door:
  • Spray foam is applied to the inside of the door, not the frame. So, the frame of the door will not be insulated and is an area for energy loss.
  • Spray foam will not be able to surround the moving parts of the locking mechanism of the door.
  • Not aesthetically pleasing.
  • R value is dependent on the thickness and type of foam. Open cell spray foam has an average R value of 3.5 per inch. Closed cell spray foam has an average R value of 6 per inch thickness.
  • Open cell spray foam will allow moisture to pass through the foam. Closed cell spray foam will resist moisture.
  • Will need to hire a company to do the installation.
  • Price varies between companies but around $2.50 CAN per sq/ft for 2” thickness is an estimate. This does not include labour.
Using a steel building blanket insulation on bifold doors is another common alternative to using a panel. Some things to consider when choosing this option are:
  • Inconsistent R value (where the blanket is compressed the R value will decrease).
  • Not aesthetically pleasing.
  • Labor intensive installation (cutting and installing the blankets onsite).
  • Price is roughly $.90 CAN per sq/ft.
If you are looking to either replace your shop door or insulate your Diamond Door, our insulation package is something to consider.
