Yes they can. The structure and panel framework are in aluminium, and the roof panels are in polycarbonate. All of these components can be re-cycled, once the life of the project is complete.
It’s very simple. Just use the contact form on this web-site, or call our office on 01925 811311 to speak to one of our internal sales team, and we will arrange for one of our surveyors to call you to arrange a site or office visit. The initial survey will normally be carried out within seven working days and within five working days of the survey we will send you a firm, no obligation quotation for a canopy that will fulfil all your needs.
Providing that the glazing bars are at appropriate centres, and combined with additional purlins, in many cases curved multi-wall and solid polycarbonate roofing can be designed as being non-fragile. Any specific requirement can be checked with our Design & Planning Department.
The Building Regulations themselves do not refer to “non-fragility” in relation to roofing systems. However, they do require that any structure is designed in accordance with the CDM Regulations, (Construction Design & Management) and these Regulations require that all buildings should be designed to utilise the safest method of construction available. (i.e. if a non-fragile design is feasible, then it should be used.)
No, in many canopies that use multi-wall or solid polycarbonate glazing, the glazing is simply clamped into a glazing bar system that just holds these sheets in place. Whilst the sheet itself might not break, a falling object, (and in some cases even a strong wind), can flex the sheet and force it out from between the glazing bars. If someone were to trip on such a roof, they could fall through, endangering themselves and anyone underneath. Remember..... just because it doesn’t break doesn’t make it non-fragile.
Yes, Twinfix ML16NF and ML25NF panel systems have been tested to ACR(M)001:2000, subsequently amended in 2005, and are classified as Class B, non-fragile. We also have a solid polycarbonate multi-link panel that also achieves a Class B result.
Non-fragile, in the context of a canopy or walkway roofing system, is a roof system that effectively prevents someone from falling through it, should they trip up whilst on the roof. It is defined by an HSE, (Health & Safety Executive), test: ACR(M)001:2000, subsequently amended in 2005. In this test, a leather bag of defined size and weight is dropped twice onto a roof system, (simulating a falling person), and must not fall through either time. If the roof, (even if damaged), is not penetrated by the falling bag, the roof achieves a Class B result and is designated as “non-fragile”. The test is carried out on complete components, and not on individual parts that may subsequently be used on a roof.
In many cases, having one of our canopies installed will not require planning consent. However, on the basis of your specific situation we can advise you whether planning consent and/or building control approval is likely to be required. If this is the case, we will provide you with advice on how to undertake a planning application.
Yes, we can undertake everything necessary to survey, design, manufacture and install your canopy. Our in-house design teams, who work on sophisticated CAD/CAM systems, can also advise on different design options for your space. We do not outsource any of these important elements. If the canopy installation is part of a larger project, we will liaise with the architect and/or builder to ensure that any works undertaken are co-ordinated with other elements of the project. Our fully trained, CRB checked installation teams will ensure that safety is paramount during every part of the installation process. We demonstrate our total Company commitment to health and safety by being an Accredited Contractor to CHAS, the Contractor’s Health and Safety Assessment Scheme.
Our canopy structures are all manufactured from virtually maintenance free, powder coated, aluminium sections. Aluminium does not rust and should never need repainting. We offer a 10-year guarantee on all our materials and on installation where canopies are fitted by one our own installation teams.
Yes, for the canopy structure you can choose any of our nine standard matt RAL colours. Should you wish to match an existing colour, we can supply our canopies powder coated in any RAL or BS reference colour. (Please note, however, that choosing some colours may extend lead times and attract an additional cost). The polycarbonate roof glazing is available in clear, bronze or opal colours to suit your specific needs.
Although polycarbonate glazing is tough and virtually unbreakable, if simply fixed into a standard glass glazing bar system, it can be vulnerable to wind and impact loadings that cause it to pop out of the bars. Our pitched canopies are different. In addition to the weather protection that they give, our canopies utilise our unique patented, factory-made, non-fragile, Multi-Link-Panel system. This means that not only is the roof exceptionally resistant to high winds but anybody who gains access to one of canopies and falls onto the glazing (whether they are authorised to be there or not), will not fall through the roof glazing. This not only protects the falling person, and anyone underneath the canopy, from possible fatal injury, but it removes the risk of any subsequent litigation. Our non-fragile, Multi-Link-Panel system is tested to the HSE test ACR(M)001:2000, amended in 2005. Do not consider using any system that does not comply with this test.
Our canopies are designed to shelter from rain and sun using tough, multi-wall polycarbonate glazing that allows light transmission, whilst filtering out virtually all the harmful UV radiation. The area under our canopies will be safe, dry, sheltered and shaded. In particularly exposed areas you may also wish us to fit vertical glazing to the sides and/or front of the canopy to give added protection and shelter from prevailing winds.
Whilst we follow standard design principles, our canopies are all designed to individual order so that they meet your specific requirements, however complex or simple your space(s) may be.
