A whole myriad or roofing and cladding options exist for new construction projects. These range from traditional and proven trapezoidal profile twin-skin and composite panel systems through to more complex and sometimes more aesthetically pleasing standing seam and flat panel alternatives.
Since the first changes to the building regulations part L2 in April 2002, installation of all of these materials has become more stringent. The intention of the latest changes timetabled for Autumn 2010 is to address still further the continued needs to reduce significantly the emission of 'greenhouse gases' from heating or thermal control apparatus. This has meant the need to address long-term issues in the assembly of metal roofing and walling components primarily to provide an airtight finish to the building concerned. The need to comply with these regulations is paramount to independent tests, such as:
- Air leakage or thermal imaging can be requested by 'Building Control' officials to any new building constructed to these regulations
Coupled with these requirements, is the additional need to comply with Safety Regulations HSG33 'Safety in Roofwork' documentation. Providing such items as scaffolding/guard rail, personnel safety netting, sensible and practical means of lifting materials and access to and from the working area.
This section is by no means designed or intended to be written as a definitive guide to the changes to part L2. It is primarily a series of points that the 'design team' must consider as part of their overall brief. Some major manufacturers have spent an inordinate amount of their time and resource to identify these issues and include answers to potential problems with their designs and products/systems. IBSL work closely with these major companies and can therefore provide the answers needed relevant to a particular design. Alternatively, the option exists to discuss designs directly with the manufacturer concerned; although practical installation maybe more relevant by consulting ourselves.
Often the more acceptable approach is to refurbish existing building stock rather than to demolish and rebuild. Especially if the building(s) is not that old or requires only minimal work to upgrade its thermal elements. Once again, several key options exist for this type of works, namely:
- Complete or partial removal of the existing coverings followed by replacement.
- Over-roofing and/or over-cladding the existing coverings.
- Isolated replacement or alterations to the existing envelope.
The above is a brief "snap-shot" of potential improvements which by careful selection of materials systems and finishes, can significantly enhance or upgrade any original building. This approach not only extends the lifespan of any building but potentially increases its net worth too.
Industrial Building Solutions Limited has a vast wealth of knowledge and a proven track record in these type of projects. Secondly, collectively from our time within the roofing and cladding industry, we have a full working understanding of the many different types of existing roof and vertical clad constructions.
These 2 main factors allow ourselves to offer sound, practical and experienced advice from inception to completion on any roofing and cladding refurbishment project.
Be they existing or prospective building owners, occupiers and/or tenants, advice and assistance can be provided for the external envelope of Industrial Properties. Industrial Building Solutions Limited offers a comprehensive service to suit client needs incorporating a number of the following areas:
- Inspection and written report detailing the existing construction and components.
- Fault finding, recommendations and written specification of works to be undertaken to rectify.
- Dilapidation surveys, assistance and rectification detailing.
- Independent advice in the event of disagreement over products, workmanship or construction detailing.
- Programmed and planned maintenance schedules to eliminate premature failure and costly replacement.
Typical inspection of a reported roof failure noting poorly installed seal over insulation board joints.
Previously leaking gutters temporarily sealed with a 'strip' of felting. Gutters continue to leak despite this remedial work. Note corroded fasteners and dirt build up to sheet tails culminating in edge peel corrosion occurring.
Poorly fixed rooflights lacking sufficient side lap mastic strip sealant or any stitching fasteners. Also fixed with undersized washers to the main fastener positions. I.B.S.L. can solve ALL these issues.
