Renka Folding Sliding Door Products

Our folding sliding doors (also known as bifold doors) transform a room – flooding it with light, making it feel bigger, brighter and more beautiful.

Our range of market-leading bifold doors is perfect if you’re aiming to create a wide and bright seamless transition between indoors and out.

Whether for a new build or a renovation, our bi-folding doors are made to measure in a range of styles and colours that will add light and energy to any space. Our bifold range offer panels of up to 1.2 metres wide and 3 metres high in any folding combination and in the widest range of colours.

Not all bifold doors are the same...

It’s our job to help specify the best system and configuration(s) for your project.

Available in over 200 powder coated RAL colours. We have bifold systems that can offer panels up to 3 metres in height and up to 1.2 metres width. In most cases we’ll help you pick a configuration that allows you to have a single pedestrian door to use as a means of access when you don’t have the bifolds fully open. We’ll also help you decide what is the best number of panels to have in your bifolds given the space that you have inside and outside.

A range of the best systems on the market

We’ll work to understand your requirements and determine the system that will work best for you.

Frequently, a set of bifold door is one of a number of glazed products that customers are looking to order, are to add light and air to their new build, extension or renovation project. We’ll introduce you to products that visually and practically work well together.

As part of the planning process, we’ll also discuss with you the threshold detail of your doors and will supply any technical details that you, your builder or architect may need.

Glass specification

Renka offers a comprehensive range of glass specifications on our products. Most products come with 28mm toughened double glazed low-E units as standard. Our standard glass units are comprised of 2 panes of either 4mm or 6mm glass (dependent on size) either side of an argon-filled chamber.

Glass units can be clear or obscure at no additional cost.

Triple glazing can be specified in most applications, subject to the size of the glass units and the products specified. Triple glazing offers slightly improved thermal efficiency and acoustic performance when compared to double glazing.

There is a range of more specialist glasses available at an additional cost, depending on the application, including:

  • Solar control glass, which reduces the solar gain/heat transmission, and can be particularly helpful in South-facing rooms.
  • Acoustic glass, which offers improved noise reduction performance and is particularly well suited to properties close to busy roads.
  • Easy clean/self-cleaning glass, which reduces the build-up of dirt on the glass.
  • Glass units with integral magnetically operated blinds within them. Available on Windows, fixed panels and bifolds ONLY (subject to maximum size criteria).
