Building Internal Wall Linings – Dry Lining

Insulated Dry Lining the interior walls are not the only way to insulate and line the inner walls of a building. Independent lining is another method where the “U” value of insulation may be marginally lower (meaning better) than even a dry feed. But it is sometimes almost impossible to maintain the building’s aesthetics, architecture and building structural integrity of existing properties except with isolated dry lining.

Note worthy features Dry Lining

Insulated dry lining is not complicated simple composite panels of expanded polystyrene foam board with a lining of plasterboard on one side. The insulation is available in several thicknesses (eg.45.5 mm to 30.5 mm), depending on your design insulation property walls. The thickness of the plasterboard liner is usually about 9.5 mm. The typical “U” factor range of an insulated liner board worked out according to BS / EN / ISO 6946:1997 is 0.33 to 0.23 w/m2k.

When it comes to fire, the 9.5 mm plasterboard panel integrity of the evacuation is complete. EPS foam is mostly air in the beads and therefore does not support combustion. In addition, there is provided a fire retardant chemical treatment factory.

Insulated dry lining with zero ODP. Although EPS is a petroleum product by product, the amount used minimal.

What are the benefits?

Expanded Polystyrene foam insulation comes in different densities, but each of them in itself is a structurally rigid self-supporting element.

rigid EPS board also provides a degree of support to the plasterboard lining makes it more impact resistance.

EPS foam board material is impervious to moisture. Therefore, the wall insulation retrofits in the dry lining boards provide excellent protection.

Installation is dry, convenient, labor-saving and economical as the only adhesive and mechanical fasteners are used (two fasteners per panel).

How are dry liner board installed?

to implement a well-insulated dry lining installation, it is important the roof lining is finished. The surface to be dry lined must be clean and dry. Although pieces of wallpaper, loose plaster and dust would be detrimental to a good installation.

In areas where heavy fighting as sinks, washbasins, etc. will be installed on the wall, timber battens, metal or plastic anchors should be placed in place to take them after lining installation.

If the holes for electrical and mechanical services and building features that must be safeguarded in liner boards these must be done to fix the dry liner boards.

All PVC insulated and covered electrical cables should be run in pipe, casing or trunking before fixing panels.

boards can be cut for the above and installation. If cut with a sharp knife, sliced ​​through to score the plasterboard liner below and then broke for a clean edge.

Adhesive mount type dry liner plates can be mounted directly to drywall or cement based adhesive. The adhesive is applied as a vertical band of folded edge down the center of the board. In the alternative, proprietary bonding material can be used.

openings, service penetrations, transitions, seams in the ceilings and floors, etc. should be thoroughly sealed with glue to minimize air leaks. Service ducts and sleeves shall be sealed with butyl rubber or similar fire and pliable material. Proprietary adhesive used to seal holes in the finished floor level.

Set packing strips and shims, place the card on the back material (brick), adjust the level, and kept the pressure till set. Two auxiliary mechanical anchors that have been fixed in advance up to a depth of at least 35 mm and 25 mm distance from the top edge is then tightened as necessary to complete.
