The Affinity Unfinished Pine range is our most cost effective internal bifold. The doors and frame are softwood throughout, meaning no hollow sections and no compromises on quality at a highly competitive price. These clear pine bifolds are supplied unfinished so you can apply your chosen paint, stain or varnish to achieve the desired result.<\/p>

These bifold systems come with all operational hardware and corresponding running gear, so all you need to provide are the handles that compliment your chosen finish. Simply pass our easy to follow instructions on to your tradesperson to have your product assembled and installed with minimal fuss.<\/p>

Our Affinity internal bifolds have no bottom track, so there's no intrusive threshold between your two rooms. This makes them ideal for fitting over exisiting flooring or installations where uninterrupted flooring is desired.<\/p>

These unfinished pine room dividers come with a matching unfinished pine frame that can either be finished to match your doors, or finish it to match any surrounding skirting and architrave.<\/p>

This 4 door system is universal, allowing you to hang it opening to either the left or the right.<\/p>","post_title":"Affinity Unfinished Pine 2820mm","post_excerpt":"","post_status":"publish","comment_status":"closed","ping_status":"open","post_password":"","post_name":"affinity-unfinished-pine-2820mm","to_ping":"","pinged":"","post_modified":"2026-09-08 07:48:01","post_modified_gmt":"2026-09-08 06:48:01","post_content_filtered":"","post_parent":0,"guid":"https:\/\/www.aspire-doors.co.uk\/?post_type=product&p=10661","menu_order":0,"post_type":"product","post_mime_type":"","comment_count":"0","filter":"raw"},{"ID":3338,"post_author":"2","post_date":"2026-05-18 13:41:49","post_date_gmt":"2026-05-18 13:41:49","post_content":"Free set of handles and \u00a320 shootbolt now included! <\/strong>\r\n\r\nHalve the work of painting your internal doors with our top-track-only Affinity White Primed range.
