The most secure doors on the market

A strong and sturdy door is essential to protect your property. Any unauthorised means of entry is eliminated with our selection of steel doors at Ask Windows Ltd.
To prove their toughness and quality, all the products are independently tested in Germany – not only for intruder protection, but also for fire resistance, heat loss,  and sound, wind and water proofing. All of which means they look good and they easily outperform any other security door on the market.

Shield security and locking mechanism

The inner door is of a combined structure: grating, steel sheet and grating again. Even if the outside grating was damaged, the door is still protected by the steel plate and inside grating.

  • 30mm of rock wool on both sides of the steel sheet (60mm in total) provides excellent noise and thermal insulation.
  • The entire structure is covered by finishing board whose colour and design you can select from an extensive choice
  • The frame is fixed in the opening by 17 pins, protected by steel liners of 24 mm.
  • Armoured locks protected by two drilling-resistant manganese plates.
  • Main and additional locks are installed in protective steel boxes.
  • Security hinges have height adjustment mechanisms.
  • On the hinge side there are eight 16mm diameter locking bolts.
  • On the lock side, there are six locking bolts and two additional bolts directed upwards and downwards. Each bolt is protected by a steel sleeve in the door frame.
  • The lock pins are protected against damage not by steel sheet, but by a 15mm thick bent profile.
