Expa-fit is Dorplan's exclusive, easy-to-fit system that comprises a fully-finished door, frame, architrave and ironmongery in one package. It can save over £130 in installation costs per doorset.*

It is supplied fully assembled and ready to hang, requiring minimal work, space and tools to complete installation. All the joiner has to do is unpack it, fix the frame into the aperture and secure the architrave. Alternatively, for site- or project-specific requirements it can be supplied flat-packed in one package or in phased deliveries.

Another benefit is that all products are CNC-machined by Dorplan to individual aperture requirements and assembled at our premises so the only site waste is the recyclable packaging.

*Calculation based on savings in time required to complete installation vs traditional door frame installation and site decoration.)

Vision Panels

Vision panels can help to increase visibility, distribute light and enhance design. In certain locations, such as entrances, they are a legal requirement with defined minimum sizes (see below).

Some of our most popular vision panel styles are shown here but we can make panels to any size and shape. For fire and sound-rated doors there may be some restrictions but we will guide you through the requirements to make sure these are maintained.


Vision panels in entrance doors

These are governed by the Government's Building Regulations parts M (Access to buildings) and K (Protection from falling, collision and impact). This diagram shows the minimum requirements for vision panels in entrance doors.

There are two main types of beading for vision panels: bolection and flush. Beading is supplied in hardwood species, with a finish to complement the door. For a fire door, intumescents are installed between the glass and the door.
