Tired of headaches trying to make a trimless door-frame – Invisibledoors® is the answer.

Some frequently asked questions about Invisibledoors®:

1: Will the plaster crack up when you shut the door too hard?

A: No, it will not if it is installed in accordance with the installation instructions.  The reason why the plaster does not crack is that Invisibledoors® is screwed every 200mm (8’’) all the way around the door frame which makes it an integral part of the wall.  Testing has been conducted to prove this.

2: What is the minimum & maximum wall thickness?

A: The minimum wall thickness with Invisibledoors® is 85mm (3-3/8’’) and the maximum is 225mm (8-3/4’’).

3: What width and height can be used?

A: Invisibledoors® can accommodate any door width up to 1000mm wide and up to 3000mm 

4: What is Invisibledoors® made from?

A: Invisibledoors® is made from cold rolled galvaneal product which is galvanised steel that has been through an annealing process so it can be painted.

5: How do you paint Invisibledoors®?

A: Invisibledoors® just needs a metal primer and can be painted with the paint of your choice.  It is also available in a powder coated finish.

6: Are the hinges on Invisibledoors® rebated in?

A: The hinges on Invisibledoors® are not rebated into our frame, because Invisibledoors® has a clean line down the edge of the frame that you plaster up to.  If we rebate into that line we lose the clean line look.  Invisibledoors.co.uk supplies a unique, high quality stainless steel ball bearing hinge (other finishes are available) that can be surface applied to keep the clean line look.

7: Can Invisibledoors® be punched for a strike plate?

A: Yes Invisibledoors® is punched out for the strike plate as standard.  A stainless steel striker plate and plastic insert is included in the price of a door frame.

8: How do the top corners join?

A: The corners of frame join together with an alignment insert which is already installed in the frame.

9: Is Invisibledoors® fire rated?

A: Invisibledoors® is fire rated to BS:Part22:1987 for 30 minutes.
