Storage, Handling and Use
Good practices suggest the following precautions.
Storage
1.
2.
Do not stack more than 2.5 metres in height. Ensure stability of stack and provide adequate aisle space for access between stacks. Store packs off the ground and on a slope, so that should rain water penetrate the wrapping, water will drain away. Support the packs evenly with bearers spaced at 2m. Bearers should always be placed one directly above another.
Installation
1. 2. 3.
During the fixing operation or whilst handling, laceration of the skin is possible on the edge of the sheet. Product is supplied in heavy bundles and injury may result from incorrect lifting or handling. Cutting the product may cause flying swarf which could injure skin, particularly eyes. Cutting can also produce dust which can cause irritation if inhaled.
Precautions
Protective clothing particularly gloves should be worn to avoid skin lacerations. Eye protection should be used when cutting. Handling sheets and bundles should be in accordance with HSE recommendations. If subject to abnormally high temperatures ensure adequate ventilation. In a fire, breathing apparatus should be worn.
COSHH
Employers must ensure that there are measures in place that will control or limit the exposure of their employees to any substance hazardous to health. Occupational Exposure Standards (O.E.S.) for nuisance dusts, e.g. urethane foam, are detailed in Health and Safety Executive Guidance Note EH40 (current issue). Further information on dust hazards may be obtained from EH 44/84 ‘Dust in the Workplace’ – general principles of protection.
Disposal Precautions
Waste foam should be disposed of regularly in a designated location in accordance with the requirements of Local Authorities and the Environmental Protection Act 1991. It is important that the accumulation of waste foam is avoided to prevent wind dispersal. Packaging material is combustible. Store away from sources of ignition prior to disposal.
Ensure polythene wrapping/packaging is kept away from children. Observe usual precautions with polythene bags.
Annual Inspection and Maintenance Parts of a building on which colour coated sheets have been used, especially roofs, should be inspected and if necessary, cleaned regularly. If any defects are found in the coating they should be repaired immediately, in order to ensure long life. This section tells you how to get the best possible performance from Kingspan Insulated roofing and walling materials by inspection and maintenance based upon that inspection. Time spent reading this section and acting carefully on its advice will repay itself in excellent service from the Kingspan used products, with the least possible maintenance. We recommend that you employ specialists to restore the coating, if that is necessary. The list of suppliers contained herein is reviewed by Kingspan from time to time and may therefore change. You should consult Kingspan to obtain the most recent information.
Updated: 2009
For buildings in the U.K. or the Republic of Ireland, clad in precoated steel and registered in accordance with the terms of the manufacturers guarantee, owners should record the manufacturers registration number. Building owners should record details of the building and keep a record of inspections and maintenance. This is an important part of the documentation of any building put particularly for buildings registered under the Kingspan and its associate coil suppliers guarantee for the coating supplied. Coil suppliers to Kingspan: Corus Plc (U.K.) Ruukki (Finland) Arcelor (Belgium) Dobel (Sweden)

Annual Inspection This inspection is based upon good practice. It should be carried out annually throughout the life of the building. Those items marked with asterisks should be checked not only at every inspection but also soon after the building is erected.
It is recommended that one should watch for changes in the condition of the coating, particularly upon approach to the end of the Period to Re-paint Decision, which is the length of time before a building owner needs to consider whether to re-paint the cladding.
What to check for Check for:
Action:
Blocked gutters
Clean and wash out any blockage.
Blockage may cause overflow into a building. Build-up of debris A build-up can cause wet poultice corrosion. Dirt retention in areas of cladding not washed naturally by rainwater, e.g. overhangs
Remove debris and wash the area as outlined in washing below. Wash down, see washing.
This affects the appearance of the building and could, if left, cause breakdown of the coating. Mould growth This rarely occurs but can arise in extreme conditions and affect the appearance. Local damage* Breakthrough of protective paint coating could cause corrosion of steel substrate.
Drilling swarf, rivet stems and other fixing debris*
Wash down and treat as described under Mould growth.
Assess extend and type of damage. Action may involve: 1. Touch-up of affected area. See Touch-up. 2. Over-paint of affected area. See Over-painting. 3. Replacement of damaged sheets. Contact the profiler who supplied the sheets. Remove debris.
These can rust and cause staining. Condition of fasteners*
Replace faulty fasteners and any missing caps.
Faulty or inappropriate fasteners can cause leakage, or rust staining on the surface of the cladding, or both. Corrosion of cut edges
Treat as described under Treatment of edge corrosion.
Corrosion of cut edges at sheet overlaps and at overhangs can, if neglected, spread up the sheet. Condition of colour coating Peeling of coating, uneven fading, blistering and cracking and local scratching are all signs of the need for repairs to the coating.
Updated: 2009
Follow the painting instructions of the recommended paint suppliers.

Maintenance Washing
Rainfall alone is often sufficient to keep exterior surfaces looking clean and bright. However, to achieve maximum life from the Kingspan product, it is important that accumulations of dirt and debris which are not removed by normal rain washing are removed regularly by cleaning. This reduces the risk of ‘wet poultice’ corrosion. Areas of cladding that lie beneath overhanging building details, such as those beneath gutters, for example, are particularly susceptible to a build-up of dirt. Such accumulations may hold water and pollutants, which can lead to ‘wet poultice’ corrosion. Washing may be carried out with a hose and a soft bristle brush, using fresh water. In areas where heavy industrial deposits dull the surface, a solution of fresh water and good quality household detergent of proprietary cleaner may be applied to ensure thorough cleaning. For household detergents, use a 10% solution; for proprietary cleaners, follow the manufacturer’s recommendations. A thorough rinse with clean water must follow the wash. Proprietary cleaners are available from the companies listed under the heading Cleaners.
Caution
When cleaning, the following points should be noted: 1. Stronger concentrations of cleaners than those recommended can damage coating surfaces. 2. Rinse thoroughly to remove all detergents after cleaning. 3. Organic solvents and abrasive cleaners should be avoided in cleaning any coated surface. Caulking components, tar and similar substances may be removed with mineral spirits but wash the surfaces thoroughly with fresh clean water. 4. Over-cleaning or scrubbing can do more harm than good.
Mould Growth
Some types of local environment are particularly conducive to mould growth, i.e. areas of wet, dark, wooded surroundings or low lying marshland. In these areas, mould will grow, even on inert materials such as glass. Mould growth can be removed by treatment with a basis solution of the following ingredients, by weight, which should be available from local chemical suppliers. Before using the first three of these ingredients, you should refer to the manufacturers’ health and safety information. Updated: 2009
Good quality household detergent or proprietary cleaner
0.5
Trisodium phosphate
3.0
5% sodium hypochlorite solution
25.0
Fresh water
71.5 100.0
Before applying this mixture, wash down the coated surface first, as explained under Washing (above), then apply the mixture to all surfaces by low-pressure spray or brush. All surfaces must then be rinsed with cold water within twenty-four hours. Most Kingspan coatings formulations have been specially developed to resist fungal growth; therefore, in most areas of the U.K. this should not arise.
Touch-up
During one of the inspections, you may find that surface coating has suffered some damage. It is better not to treat the surface of the Kingspan product if it has been only slightly scuffed. If it is scratched more deeply, say, down to the substrate, the damage can be repaired easily by applying standard touch-up paint. It is important to ensure that the applied paint is no wider than the original scratch. To achieve this, the paint should be applied with an artist’s or child’s medium to fine paint brush. Touch-up paints are, of necessity, air drying; over the years they will change colour differently from the original stoved coating. For this reason, it is good practice to keep the applied area as small as possible. Touch-up systems are available from the suppliers listed under the heading Touch-up paints.
Treatment of Edge Corrosion
Corrosion at the edges of the profiled steel cladding should be rectified as described below. 1. Cut and remove, or abrade, any loose organic coating back to a firm point. 2. Remove all white and red rust by sand blasting to BS 4232 second quality (Swedish Standard ST2) or by abrading to bright, firm metal, ensuring that the surface is not polished. Thoroughly clean and dry these surfaces before applying the specified materials which must be applied as directed by the recommended paint system manufacturer. 3. Coat the prepared areas with the relevant anticorrosive primer recommended by the materials supplier. Page 5 of 8
Maintenance 4. When the first primer coat has dried, apply a further primer coat in a neat band to the prepared areas so that the primer extends beyond the prepared area, covering the original surface. 5. Apply a top coat to the dry, primed area. Materials are available from the suppliers listed in the separate appendix under the heading Treatment of edge corrosion.
Over-painting
External Sheets Surface preparation and over-painting of cladding should be carried out by specialist contractors using approved maintenance paints. The paints are available from the supplier listed under the heading Overpainting. Bright White Lining Enamel Kingspan lining enamel has been designed for easy over-painting. When over-painting is deemed necessary, the panels or trays should be cleaned as explained under Washing (above) and painted with brush, roller or spray using a standard household undercoat and finish system. Cellulose-based paints should not be used.
From the point of view of the durability of coated sheet the most detrimental are knocks and scratches, in which the impurities come into direct contact with zinc, which are easily soluble, as a result of which the zinc is rapidly consumed. In addition a number of the impurities absorb water, which keeps the damaged area wet longer and as a consequence rusting is active longer. The effect of the impurities in the air is greatest when close to polluted industrial areas and in coastal areas. These are typically produced, e.g. from power stations burning fuels containing sulphur. Impurities stress the coatings and reduce their useful life, so the regular cleaning of wall and roof surfaces is an important part of the servicing and maintenance of coatings.
Removal of Debris
Rainwater is usually sufficient to keep colour coatings clean. Leaves from trees and other debris is not always washed away by the rainwater and so should be removed annually, or more often if necessary. The roof valleys and rainwater system should also be cleaned at least annually.
Care
Colour coated metal sheets used on the roofs and facades of buildings are exposed to many kinds of pollution in the air. These together with water and increasing amounts of UV radiation affect the coatings. The effects are worst on those areas of the building where impurities are not washed away by rainwater. Some impurities may also cause internal stress in the coating and even cracking.
