K10 Plasterboard Dry Lining/Partitions/Ceilings

CONSIDER:
• Airtightness should be achieved in the building fabric not the finishes.
• Airtightness in plasterboard construction is easily achieved with plaster skim but air leaky construction behind will loose heat too.
• Acoustic, airtightness and fire proofing sealants help to maintain air tightness.
• Clayboard as a substitute for gypsum (thicker and greater thermal mass).
• Dense gypsum reinforced with cellulose fibre or timber chip boards.

WASTE:
• Gypsum is now classified as 'Stablel non-reactive hazardous waste'.
• It can be stored in specifically licenced landfill sites.

RECYCLE:
• Use gypsum recycled from electricity generation recovered from desulphurisation process.
- British Gypsum use waste products from desulphurisation in flues gases in electricity generation industry in their boards.
• British Gypsum also offer a take-back scheme, but presently limited to housing.
• Knauf Drywall and Lafarge Plasterboard offer boards of heights made to measure to reduce waste but don’t offer recycling take back schemes.
• Fels-Werke will make Fermacell boards to fit the wall height and width of the room. Wall, ceiling and floor lining.

ALERT:
• Drylining tends to produce leaky buildings in airtightness testing.

AVOID:
• Thin insulation on insulated drylining.
• Empty irregular shaped voids- insulate them!
• Wall linings which will affect the exhibits in museums and art galleries.
• Floor finishes which will affect the exhibits in museums and art galleries.

K11 Rigid Sheet Flooring/Sheathing/Sarking/Linings/Casings

CONSIDER:
• Clayboard as a substitute for gypsum.

RECYCLE:
• Some suspended floor support stools can be found made from recycled PVC.

AVOID:
• Wall linings which will affect the exhibits in museums and art galleries.
• Floor finishes which will affect the exhibits in museums and art galleries.

ALERT:
• Waste disposal of Gypsum - see K10.

K13 Rigid Sheet Fine Linings/Panelling

CONSIDER:
• FSC approved timber sources and timber based materials See Z10
• Natural finishes See M60

AVOID:
• Tropical hardwood, See Z10
• Indonesian Hardwood, See Z10
- Most is illegally logged, destroys forests, communities and habitat.
• Wall linings which will affect the exhibits in museums and art galleries
• Urea formaldehyde in all timber based boards
• Synthetic finishes See M60.

ALERT:
• Waste disposal of Gypsum - see K10.

K14 Glass Reinforced Gypsum Linings/Panelling/Casings/Mouldings

RECYCLE:
• Use gypsum recycled from electricity generation recovered from desulphurisation process.
- British Gypsum use waste products from desulphurisation in flues gases in electricity generation industry in their boards.
• British Gypsum also offer a take-back scheme, but presently limited to housing.
• Knauf Drywall and Lafarge Plasterboard offer boards of heights made to measure to reduce waste but don’t offer recycling take back schemes.
• Fels-Werke will make Fermacell boards to fit the wall height and width of the room. Wall, ceiling and floor lining.

ALERT:
• Drylining tends to produce leaky buildings in airtightness testing.
• Airtightness should be achieved in the building fabric not the finishes.
• Acoustic, airtightness and fire proofing sealants help.
• Plaster skim helps achieving airtightness too .

AVOID:
• Thin insulation on insulated drylining.
• Empty irregular shaped voids- insulate them!

K15 Vitreous Enamel Linings/Panelling

CONSIDER:
• Extremely long life product 100 years externally, 200+ internally?
• Is colour fast finish, glass chemically bonded to steel backing sheet..

RECYCLE:
• Difficult to fully separate glass/metal composite but melting of scrap in steel making should over come this.

K20 Timber Board Flooring/Sheathing/Linings/Casings

CONSIDER:
• Acoustic isolation rubber matting to minimise impact noise transmission from above to below.

K21 Timber Strip/Board Fine Flooring/Linings

CONSIDER:
• FSC approved timber sources and timber based materials See Z10.
• Natural finishes See M60.
• Acoustic isolation rubber matting to minimise impact noise transmission from above to below.

RECYCLE:
• Some suspended floor support stools can be found made from recycled PVC.

AVOID:
• Tropical hardwood, See Z10
• Indonesian Hardwood, See Z10
- Most is illegally logged, destroys forests, communities and habitat.
• Wall linings which will affect the exhibits in museums and art galleries
• Urea formaldehyde in all timber based boards
• Synthetic finishes See M60.

K30 Panel Partitions

RECYCLE:
• Use recycled aluminium in preference to virgin aluminium, significant reduction in CO₂ generated.
• Design for recycling: avoid coatings as they discourage recycling due to the high levels of purity required in aluminium, PPC and PVF2 are more difficult anodizing is an alloy of aluminium and is more readily recycled, mill finish is best but not everybody likes the oxides that form on aluminium.

K32 Framed Panel Cubicles

CONSIDER:
• T he core of laminated boards are ply, chipboard, etc. usually made 1200 x 2400 mm. and cut to size
- So if a cubicle can be 1200 mm. this is good, 1300 mm. will throw away 1100 mm

RECYCLE:
• Use recycled aluminium in preference to virgin aluminium, significant reduction in CO₂ generated.
• Design for recycling: avoid coatings as they discourage recycling due to the high levels of purity required in aluminium, PPC and PVF2 are more difficult anodizing is an alloy of aluminium and is more readily recycled, mill finish is best but not everybody likes the oxides that form on aluminium.

K33 Concrete/Terrazzo Partitions

CONSIDER:
• Cement and aggregate substitution in concrete elements. See E10.
• Recycled glass substitute for aggregate.
• Natural plant extract binder.

RECYCLE:
• Glass as an aggregate in terrazzo-like panels.

AVOID:
• Synthetic resin binders.
• Alkali aggregate reaction between cement and glass.

K40 Demountable Suspended Ceilings

CONSIDER:
• Margins to maintain whole tiles without cutting tiles or grid.

WASTE:
• Gypsum is now classified as 'Stablel non-reactive hazardous waste'.
• It can be stored in specifically licenced landfill sites.

AVOID:
• Uncontrolled dimensions for modular ceiling grids.

K41 Raised Access Floors

RECYCLE:
• Use recyled flooring cover for access floors.

AVOID:
• Uncontrolled dimensions for modular floor tile grids.

K42 External Suspended Soffits

RECYCLE:
• Use recycled aluminium in preference to virgin aluminium, significant reduction in CO₂ generated.
• Design for recycling: avoid coatings as they discourage recycling due to the high levels of purity required in aluminium, PPC and PVF2 are more difficult anodizing is an alloy of aluminium and is more readily recycled, mill finish is best but not everybody likes the oxides that form on aluminium.
