What type of material do I use to cover SLIDEHIDE cavity wall?
For brickwall (wet wall) models, use cement-sand plaster (wall tile can be applied directly if required) to cover the cavity wall.

For gypsum board (dry wall) models, use wood or cement based board to cover the cavity wall.

What is the finished thickness of the SLIDEHIDE cavity wall?
For brickwall (wet wall) models, the finished plastered thickness is 140-150mm for single leaf door and 180mm for double leaf door.
For gypsum (drywall) models, the finished thickness with 12mm board each side is 110mm for single leaf door and 168mm for double leaf door.


Will there be any problem with the cavity system?

Once the system is installed with the correct alignment and verticality, the cavity system will become rigid once the cement-sand plaster is applied on the brickwall models, or board is fastened for the gypsum models.

What if I need to change the door panel, do I need to hack the cavity wall?

No, you don’t. You can take out the door panel by removing the top door frame and disengage the rollers from the hanging brackets.

What is the benefit of SLIDEHIDE cavity system versus the built-on site cavity/pocket door?
• Sliding track is not mounted to the lintel
• Sliding track will not sag and thus door will not get trapped
• Consistent workmanship and the cavity system has constant thickness
• Slim thickness to match adjoining wall
• Seamless wall finish with adjoining wall
• No crack at the joint with adjoining wall
• Built on site system will tend to be thicker – at least 200mm. It can be an eyesore. If similar thickness of adjoining wall is used, it will be very flimsy.
My contractor says his carpenter can do the same cavity door as SLIDEHIDE. What is the fallacy?
• Cavity door done by carpenter is usually made of timber framing and is cladded with gypsum board. The timber frames will tend to expand and warp when exposed to moisture and will scratch the door in long term. Fungus may grow on the timber frame.
• The junction between the cavity door and adjoining brickwall will tend to crack due to dissimilar material, as well as vibration caused by door movement and slamming.
• The track will tend to sag and cause the door to scratch the floor or even get stuck.
• The carpenter does not warrant against his workmanship nor parts he purchased
What is the advantage of SLIDEHIDE Cavity System versus exposed sliding door?
• More high class appearance
• The exposed sliding door prevents the usage of the wall. Hence, there is no saving of space
• With SLIDEHIDE cavity wall, the sliding door disappears into the wall. Hence, the face of cavity wall can be used to hang towel rail or picture.
Can I mount electrical switch box and conceal it on the cavity wall?

Yes, you can run conduit along the casing and place the switch box onto SLIDEHIDE cavity wall and plaster accordingly.

Can I use in toilet area?
Is there a bottom track?

No. There is no bottom track

Can I mount objects (such as painting, LCD screen) onto the cavity wall surface?

Yes, you can. You can consult us if you need more detail.

How many years can the SLIDEHIDE Cavity Wall last?

As the cavity system is covered with cement-sand plaster or board, it will last as long as the structural elements. The rollers have been tested under International Standard and can last more than 15 years under normal usage.

Does the door panel protrude out of the cavity system?

Under our standard design, the door panel is flushed with the door frame when the door panel is fully opened. The door panel can protrude, if the design or usage requires so, by modifying some dimension.

Will insects or rodents hide inside the cavity door?

As there is no food and the cavity is made of steel, such problems do not exist.

Will there be any water ponding in the cavity base?

No, the bottom of the casing will be flushed with the finished floor level.
