Here are the most frequent questions of our customers. Maybe you too will find answers to your questions here.

  • Can I buy a door directly from you - the manufacturer?

    Our company is only involved with the production and wholesaling. We recommend our clients to turn to our local retailers. On our web site there is a list of our most important customers.

  • Do you make atypical door?

    We specialize in serial production in accordance with the European standards, but we are also capable of fulfilling our customers' requirements and making atypical doors.

  • What's the spacing of the used lock?

    At all interior doors, to include the fire-resistant door, there is a lock with 72mm spacing. At the safety door the lock spacing is 72 or 90 mm.

  • Do you provide the door together with metal mounting?

    The door has a lock and mounts, which are included in the price. Door top metal mounting (rosette/gable mounting, door closers, cylindrical inset, etc.) is not included in the price.

    Customers can also choose some types of mounting and accessories from our offer at pricelist and catalogue (the mounting is packed and enclosed with the door).

  • What type of glass do you use for glazing?

    Due to the highly demanded sandblasted glass at the majority of orders, we have chosen this type as a standard. At smooth white, laminated 2/3 and Masonite lines of profiled door we normally use bark clear type glass.

    The glass can be exchanged for free for another type of glass from our offer, if the customer requires it. This change needs to be made in the order though.

  • What type of doorframe is the door intended for?

    Since it's a standardized door in line with ČSN 74 64 01, it can be placed into standardized steel or lined doorframes.

  • How big should be the opening for doorframe covering?

    The opening for standard doorframe covering should always be wider by 8-10#160;cm than the door's width and higher by 4-5 cm than the door's height.

    Příklad: The door's width/height is 80/197#160;cm, which means the opening must be 88-90#160;cm wide and#160;201-202#160;cm high. The height is measured from the finished floor.

    Doorframes are normally mounted on finished floor and plastering. Fire-resistant doorframe covering should be placed into an opening of +11,5#160;cm door width and +6#160;cm door width.

  • Can I choose a different colour?

    At doors which have acrylate white surface finish, it's possible to apply other colour from the RAL sample book, see Ceník.

    At laminated doors (laminated, HPL, CPL, 3D), only décors that are currently on our offer can be applied, see catalogue.

  • How is the door marked?

    At each product there is a production label at the door's bottom edge. The label contains data on the door type, surface finish, décor, dimensions, orientation, date of manufacture and EAN code.

    Safety and fire-resistant doors have identification labels, which are normally placed on the door's lock or hinge side.

    The identification label contains information on the fire resistance class, door type, serial number, conformity mark, other declared characteristics - safety, noise reduction).

  • Who can mount the interior door?

    Our company doesn't mount the door, but we provide training to companies which deal with door mounting.

    Since it's a standardized product, every construction company should follow standard mounting procedures.

    If you mount the door into a prepared dooframe yourself, before you start mounting it's important to adjust the screw hinges in such a way, so that when the door is mounted, the space around the door is even on all sides. This way the door won't get scratched or otherwise damaged.

    If the doorframe is deformed so that the door can't be mounted by any means, we recommend to hand over the door mounting to a specialized company.

  • Who is authorized to mount and inspect the function of fire-resistant and other specialized doors?

    Only trained personnel, authorized by the manufacturer with a door mounting and fire safety equipment inspection certificate. Our company provides regular training on mounting and functionality inspection of fire safety equipment for personnel/companies.

    See our web site news for training dates or contact us at czechinfo@masonite.com

  • Can I shorten the door?

    Regular interior door (full/glazed/profiled/sliding) can only be cut by 1,5 cm max. If the door needs to be cut more, try to widen the doorframe or contact Masonite's Technical Department, see Kontakty

    • LUME EXTRA fire-resistant doors and their subsidiary versions (that have LUME EXTRA in their names) can be cut by 2,5 cm max.
    • Safety doors (not versions of LUME EXTRA) can be cut by 1 cm max.
    • Klima doors can be cut by 1 cm max.
    • Glazed fire-resistant doors can be cut by 2 cm max.

    Any other modifications than those listed above, should be consulted with the retailer.

  • What is the best way to transport the door?

    It's best to transport the door in large enclosed cargo spaces. It's not recommended to transport the door on vehicle top or open trailer. There's a strong chance of the doors being scratched or damaged by water in rainy weather (or residual water afterwards), bending, if supports are not even, glass breaking, etc.

  • How to store and keep the door?

    Door must be stored in a horizontal or vertical position, always supported in such a manner, so they couldn't bent (meaning the whole length of the door). The storage place should be dry and well aired.

    The surface can be cleaned with a wet piece of cloth with detergent that doesn't contain organic solvents or other corrosive compounds.

    For more information see Conditions for storing and maintenance

  • How is the door packed?

    The door itself, actually the door edges, are packed in cardboard packing and the whole product is protected with stretch foil against dust and dirt. Glazed doors are protected with honeycomb strips, packed in clear plastic film, which is heat-sealed on the sides and the whole product is this way enclosed in a plastic film package .

    Pallets with doors are then packed and protected with additional cardboard protecting product's critical spots during transport.

  • What is airhole?

    Airholes enable the circulation of air in the area behind the door. Airholes are made of white or beige plastic and normally is covered with a sieve. Airholes can be placed at the door's bottom or top. Apart from airholes, ventilation grilles can be used as well. They are made of white or beige plastic too. See price list for the prices with airholes and ventilation grilles.

  • Does your company follow the obligations arising from the Act No. 477/2001 on Packaging?

    We have entered into a Joint Performance Agreement with EKO-KOM a.s. company, which came into force on 1/7/2002 and we fulfil our obligations to recycle the waste from packing in accordance with § 13 Art. 1 Let. c) of the Act on Packaging and we also joined the EKO-KOM's Joint Performance System under client number EK-F00024887.
