Further Details:

We are very excited to now supply the Danish made Lacuna Bi-Fold Doors range.
These stunning wooden Bi-fold doors offer unique durability and exceptional performance not usually associated with Bi-Fold doors.

We have chosen to add this product to our ranges as we feel it equals the quality of our German ranges. The product firmly kicks into touch many of the traditional problems and difficulties in using Bi-Fold Doors in a project.

Lacuna Bi-Fold Doors are a totally new approach to Bi-Fold doors and really bring the outside in coupled with astounding performance. Performance is so often the failure point of Lacuna Bi-Fold Doors competition with stories on Youtube of leaking and draughty Bi-Fold Doors being commonplace. There really isn’t much not to like about this product. Architects are sitting up and taking note as its so different.

Lacuna products use German Made Heat treated Beech; offering the slimmest profile of any timber bifold door. This timber has a rather special characteristic of class 1 durability (very similar to teak) and all importantly offers very low U Values and high airtightness. See the technical downloads and test data for more information. Unlike many bifold, this product also offers exceptional watertightness.

Lacuna products can either be provided painted or oiled. When using German Heat Treated timber, painted doors that are not particularly exposed often don’t need further treatment for 20 years. The product is also available in a range of other timbers such as mahogany and eucalyptus.

The painting process used for these exceptional units is founded on automotive manufacturing techniques with a 2 stage prime and sand process with 2-3 layers of finishing paint then used depending on the colour.

Configurations and Accessories

We are able to offer a very attractive range of configurations: allowing the doors to be used effectively as simple day-to-day exits and also allowing the user to bring the outdoors in when it suits. Again this feature redefines Bi-Fold Doors. The owner of Lacuna designed the product in mind to eradicate many of the typical objections to using Bi-Fold Doors. He put it in his own home (pictured) refined, redesigned, lived it and got the design just perfect. It really shows when you see and use the product. Like a product with excellent user testing Lacuna Bi-Fold Doors are a joy to use.

There are also some very nice design additions such as built in blinds that actually work! They will not jam and spares are readily available. We are mightily impressed all round with this simply stunning product that rewrites all the rules about Bi-Fold Doors.

Lacuna Bi-Fold Doors are a very valuable addition to our ever increasing range of products.

Each month, we introduce more innovative, modern window and door products, exclusive to Enlightened Windows in the UK.
