Key Features

Our Contemporary Naturelle selection of external timber doors offer absolute excellence

As with all the timber doors you see throughout our website, these are purely a handful of examples of the type of styles we can create; you have to remember that everything we do is bespoke, so it is impossible to show you everything! Designed to your specification and incorporating the most advanced technical features, you can look forward to all of this from a JCK Joinery Secured By Design timber door:

  • Made to measure doorsets
  • Traditional joinery construction
  • Complete doorsets as standard, doorset complete with door, frame and ironmongery
  • Added security with double glazing, (patterned, stained and obscure glass are available)
  • Paint or stain finishes available
  • Range of hardwoods

Excellent ratings in the following:

  • Thermal U-values
  • Secured by Design SBD PAS24:2016 security
  • Acoustic properties


The development of thermal performance timber doorsets has become important to assist with improving energy efficiency in the home and commercial buildings. At JCK we strive to continue to lower the U-values of our doorsets.

We currently have some of the lowest U-value timber doorsets in the UK, with ratings below 1.4 W/m2k. Our Technical department has the technology to calculate U-values for the most bespoke doorsets.

Our thermally efficient doorsets are manufactured in accordance with EN ISO 10077 – 2:2007.

Side and Top Lights


Side and top lights

To complement any doorset we offer side screens to match any door design, style or finish. Our side screens can be boarded, paneled or glazed with fixed or opening windows. All side screen variations can be certified by Secured by Design (SBD) PAS24:2016 and fire rated. Further options and  details upon request. 

Our options for side panels and side and top lights Include:

Glazed Panels: You can have glazed side panels to match or complement the glazing already used on your  door.

Solid panels

You could have solid panels with no glazing.

Mix and match

You can also mix and match your choice so that a solid front door can have a glazed side panel and vice versa.

Side panels

Side panels are frames which sit either side of your door and are used if your property requires a wider fitted entrance space. They provide an attractive alternative to traditional side and top light window frames. They are handcrafted to match or complement your door.

Door side & top lights

An attractive solution for wider entrances which also allows more natural light to shine into your home.


Glazing is available in various options; the standard glazing for our doorsets and side screens use 6.4 laminate on the external side for security, and 4mm toughened K on the internal side for safety. For fire rated doors and screens, JCK Joinery has both internal and external fire glass. The glass can be clear or wired, with integrity and insulation values of 30-60-minute fire ratings available.
