Ahmarra specialise in manufacturing pre-hung doorsets, otherwise known as pre-assembled doorsets, making them quicker and easier to install on-site.

Available in a range of styles, our flush and panelled internal doorsets can be tailored to meet the unique requirements of your construction project, whilst retaining comprehensive fire certification in accordance with Building Regulations. Our ability to manufacture doorsets using veneers, laminate or tailor-made finishes presents architects and designers with a wide range of possibilities.


What are Pre-hung Doorsets?

The British Standard BS EN 12519 defines a fire doorset as;  ‘A complete unit consisting of a door frame and a door leaf or leaves, supplied with all essential parts from a single source’. This means that the door leaf is pre-hung in its frame whilst still at the factory; with hinges, glazing system (glass, seal, bead & fixing), fire and (if required) smoke seals and ironmongery. Doorsets are supplied as fully finished units with a single fire certificate.


Benefits of Pre-hung Internal Doorsets

The benefits demonstrated by the use of factory assembled doorsets are becoming widely recognised, as more and more specifiers & contractors are advocating their use. Major savings in time and money can be achieved by specifying pre-hung fire doorsets.

    • Doorsets are tailored to suit your bespoke project
    • Doors are available with a range of design options
    • On-site adjustments are minimised as tolerance and clearance gaps are preset
    • Pre-defined ironmongery is supplied as standard
    • On-site labour costs and installation time are reduced
    • The risk of damage is diminished as doors can be fitted later in the project
    • Moisture content is controlled lessening the chance of differential shrinkage
    • All doors, frames and ironmongery are supplied from one source, ensuring full compliance
    • All of our doorsets are third-party BM Trada Q-Mark certified

Our installation experience gives us a full understanding of pre-hung doorsets. We can offer well-informed advice on how to make this process cost-effective, simplifying the specification process.
