44mm Foamcore Doors

Welcome to John Fredericks
The Ultimate Collection - John Fredericks


Monza Solid Situ

The Ultimate FoamCORE door offers a high level of security, with increased resistance to forced entry, and reinforced GRP skins as standard. 

With the Ultimate FoamCORE, the emphasis is firmly on choice with a comprehensive range of designs, finishes and colours. 6.8mm laminated units supplied as standard.

The Ultimate FoamCORE composite door is the minimal-maintenance alternative to traditional materials. It has 44mm reinforced GRP skins, finished in either woodgrain or an exclusive smooth/etched finish that perfectly matches aluminium, delivering kerb appeal for any property. 

The Ultimate door out performs other market alternatives with outstanding thermal performance. Inside, the PU foam core reduces heat loss and is encompassed by an LVL (Laminated Veneer Lumber) subframe to provide strength and rigidity. The door protects the home from the elements and will have minimal thermal expansion and contraction rates under extreme temperature variations which is perfectly normal.

  • Stiles and Rails are manufactured from a water-resistant polymer
  • LVL (Laminated Veneer Lumber) is used as the main internal reinforcement
  • Skins and sub frame are bonded with a Urethane Adhesive Resin
  • The door is filled with CFC-Free Polyurethane Foam density 44.5 – 45.5g/㎥
