ROOFLIGHTS & ROOF VENTS Rooflight types and performance have Capitalising on rooflight specification developed extensively since the days when a simple piece of glass was used in place of a roof slate to admit daylight to an otherwise gloomy space. Across the industry, there is now an infinite variety of rooflight shapes, sizes, and glazing options to suit flat, pitched and curved roof applications, whether it is a small dome-light in a domestic kitchen or polycarbonate and GRP sheeting used in stadium canopy applications. There is, however, one element which binds these daylighting solutions together. Irrespective of the number or extent of rooflight units required in residential, commercial, industrial or agricultural structures, the same approach and principles apply to the specification and installation of rooflights. For a rooflight to work practically, the early involvement of a rooflight manufacturer and specialist installer on a project can provide good advice at design stage and provide the appropriate level of input. It’s important to be wary of unproven performance claims, particularly in terms of durability. Discuss the daylighting needs From the outset of any rooflighting project, irrespective of size, it’s critical that all parties Higher levels of daylight in buildings is becoming the norm worldwide and manufacturers are producing a vast array of rooflighting products that allow contractors and their clients to achieve various design and performance standards. Ian McKane, technical service manager of Brett Martin, provides, from the company’s experience in both domestic and global markets, insight into achieving common best practices during the specification and installation of rooflights. As he points out, sufficiently detailed preparation can reduce or eliminate known or predictable weaknesses in projects... communicate relevant, necessary and adequate information effectively. This relates to the functional, regulatory, aesthetic and budgetary requirements, alongside the practical site handling and fitting of the product. Furthermore, client and building use requirements, along with respecting the designer’s vision, should be given due consideration. By evaluating a building’s internal environment and specific function, an appropriate level and quality of daylight can be achieved. In the UK and Ireland, as elsewhere in the world, rooflights are generally made from differing configurations of either GRP or polycarbonate, while some incorporate glass. Each offers differing properties in respect of durability, light transmission level, solar control, thermal and acoustic performance, ventilation options and aesthetic appeal, providing a basis for product selection to satisfy both performance and architectural criteria. Meeting regulations Compliance with the differing national regulatory frameworks must be considered, with rooflights subjected to mandatory legislation and standards covering key performance factors including fire, thermal insulation, safety, and in certain applications, security. Care should be taken to ensure that any specification and installation meets the relevant standards, with a hierarchical approach often best practice. Meeting the relevant fire standards is paramount in terms of safety; insulation standards are important to meet energy efficiency standards, while safety requirements must be also satisfied. In particular, in the UK and Ireland, much assistance in meeting regulatory requirements is provided in extensive industry guidance, for example from the NFRC, MCRMA, NARM and ACR. ���������������������������������������������������������������������������� smoke vents & hatches Fully certified, compliant and CE-marked, our daylighting products and life-saving devices surpass both regulations and expectations.
