Fixings
Steadmans supply a bar and bracket spacer system for installing the liner and weather sheet, as well as a full range of fixings.

Insulation
Mineral or glass wool insulation can be used to provide appropriate fire, thermal and acoustic performance.

Gutters
Steadmans manufacture and supply a range of gutters to match the profiles.

Gutters are produced from a variety of materials including pre-galvanised steel (to BS EN 10143:2006) and pre-coated steel, either painted or PVC-coated on one or both sides; aluminium can be supplied to order. Complete gutter systems and accessories can be manufactured to specification, up to 10m long and 3mm thick: contact Steadmans' sales office for details of sizing.

Flashings
Steadmans manufacture a range of flashings to match the profiles in Plastisol leathergrain, polyester, Nova, Scintilla, galvanised, or PVDF finishes. Flashings can be supplied in lengths up to 6m in traditional profiles, or can be shaped to meet special customer requirements.

Sealants
Steadmans supply a range of NFRC Class A butyl sealants, profile foam fillers and expanding foams to enable profiles to be sealed to each other and to other building components, so avoiding thermal bridging and air leakage.

Rooflights
Steadmans offer a range of site assembled in-plane rooflights to match the dimensions of AS twin skin profiles (see table 27). Triple skin site assembled rooflights are available for projects where U-values of 2.2W/m²K* are required: they consist of two skins of GRP, which are installed with the liner and weather sheets, and an intermediate insulating layer of polycarbonate. Double skin rooflights may be used on projects where higher U-values are acceptable.

Rooflights can be supplied to meet project requirements for light transmission, durability, non-fragility rating and fire resistance: contact Steadmans' sales office for details.
