Building Internal Wall Linings - Dry Lining

Covered Dry Lining of internal walls is not the only way to insulate and line the inner walls of a creating. Unbiased lining is another method where the "U" value of insulation may be marginally lower (which translates to mean better) than even dry lining. However it is sometimes near impossible to take care of the building aesthetics, system features and building structural integrity in existing properties with the exception with insulated dry lining.bs en iso bs en

Note worthy popular features of Dry Lining

Insulated dry lining can be a non complicated simple grp composite panel of expanded polystyrene foam slab which has a lining of plasterboard one side. The insulation is available in several thicknesses (for example. forty-five. 5 mm to 30. 5 mm) subject to your design insulation property or home of walls. The thickness with the plasterboard liner is usually about 9. 5 mm.

The normal "U" factor range of insulated liner board worked out according to BS/EN/ISO 6946: 1997 is usually 0. 33 to 0. 23 w/m2k.

In regards to fire resistance, this 9. 5mm plasterboard supplies the panel integrity till evacuation is actually complete. The EPS foam a brand new air in beads and for that reason does not support combustion. Additionally it is given a fire retardant chemical treatment in the factory.

Insulated dry lining has zero ODP. Though EPS can be a petroleum by product, the number used is minimal.

What are the advantages?


  • Expanded Polystyrene Foam insulation comes in several densities but each one of them by itself is a structurally rigid self accommodating element.

  • That rigid EPS board also gives a degree of support on the plasterboard lining making that more impact resistance.

  • This EPS foam board product is impervious to wetness. Consequently in wall insulation retrofits that dry lining boards provides excellent protection.

  • Installation is dry, simple, labour saving and economical as only adhesives and mechanical fasteners are utilized (two fasteners for each panel).

How are dry liner board installed?


  • To carry out a good insulated dry lining installation it is crucial the ceiling lining is usually completed. The surface that has to be dry lined must end up clean and dry. Even bits of wall paper, loose plaster and dust are going to be detrimental for a superior installation.

  • With places where heavy fixtures like sinks, rinse basins etc. are to be installed on the walls, timber battens, sheet metal or plastic anchors ought to be placed in place to adopt them after lining installation.

  • When holes for electro foot orthotics services or building features ought to be accommodated on the linerboards these ought to be done prior to fixing the dry liner panels.

  • All PVC insulated and sheathed electrical cabling ought to be run in conduit, casing or trunking in advance of fixing panels.

  • The boards can be sawn for the above and installation. If cut using a sharp knife, that insulation is sliced through to score the plaster board liner beneath and snapped for a clean edge.

  • Adhesive fixing type dry liner boards can be fitted directly with plaster or cement based adhesives. Your adhesive is applied as vertical bands in the board edge down the centre of board. Inside alternative, proprietary bonding material can be utilized.

  • Openings, company penetrations, junctions, joints at ceilings and floors etc ought to be thoroughly sealed with your adhesive to minimise air leaks. Service penetrations and their sleeves should be sealed with butyl rubberized or equivalent fire challenging and pliable material. Proprietary adhesives are used to seal gaps in the finished floor level.

  • Insert packing strips and shims, place the board in the backing material (walls), adjust abilities, together with kept pressed till arranged. Two Secondary mechanical anchors which were fixed in advance up to depth of at minimum 35 mm and with 25 mm spacing in the top edge are then tightened as necessary to finish.
