Increasing number of burglaries is a huge concern in our society and we have a solution for it. Regular locks and chains are easily hacked without making too much noise. Most of such doors are made from poor quality materials used in mass production. Research shown (from ONS) that burglaries in 2017 has risen by 30% and there has been over 200 000 burglaries recoded in 2017 and very high number of them were not solved. The times are changing rapidly therefore you can’t take any risks on security. Traditional doors made from wood or plastic do not have a chance to withstand burglars nowadays. Regular doors also have poor thermal, acoustic insulation. Here at Knight’s Mark by applying our knowledge and experience we help to improve your homes or businesses security aspects.
