Why dFendor?

  • Impact Resistant. In-house testing has shown that dFendor doorsets can prolong the longevity of the door face over x40 times compared to standard doorsets.
  • Aiding Infection Control. Resistant to over 200 cleaning chemicals, easy to clean and will not deteriorate with cleaning routines.
  • Fire Compliance. All our doorsets are put though burn to death test in certified laboratories by third-party industry recognised assessors
  • Lowered Maintenance costs. Many Doorsets will be in need of constant repair, with our dFendor Doorsets this will continue to perform at 100% throughout its life, with no need for spot repairs or quick touch-ups.
  • Permanent Colouring. dFendor is a solid core product so whilst not only a resilient product is also a solid colour core so does not change or fade at all in usage.

Specification Details

Heavy Duty Core

All our dFendor non-fire rated Doorsets come as standard with our Heavy Duty Core. Stable and balanced, these consist of very densely packed timber particles, and typically have a generically consistent structure making these cores very predictable to work with

Acoustic Core

With our non-fire rated Doorsets we are able to offer a higher acoustic rating thanks to our acoustic core. This core can be up to  59mm depending on your acoustic requirements. As standard, we use a spruce laminated core, both lightweight and stable.

Acoustic Ratings

Our dFendor Non-Fire rated doorsets can be manufactured to meet the following acoustic ratings:

  • NA – No Rating
  • 30dB
  • 32dB
  • 35dB
  • 40dB (Acoustic Core)
  • 40dB + (Acoustic Core)

Colours & Finishes

dFend – Premium thermoplastic available in Cashmere texture.

durablend – PVC-free thermoplastic available in Cashmere texture.

Woodgrains – Timber effect thermoplastic, smooth finish.

Hydroclean – Hygienic thermoplastic, smooth finish.

Split Frame

Designed to assist in overcoming any structural opening depth variations, the lining is divided into two pieces, each with an integral architrave. The doorstop is then fixed so as to hide the joint between the two pieces

Fixed Frame

This system comprises a standard lining post formed in dFend with separate stops and architraves. These are supplied with loose dFend.  Post formed covers to conceal fixing points

Frame Finish

Each frame type can be supplied clad in dFend, durablend or Hydroclean protection. Alternatively, the timber core can be lacquered or prepared as a pre-primed finish.
