GFRC is an ideal material to use on a variety of roofing structures. It is lightweight but tough, easy to fix and unaffected by environmental conditions. It can imitate traditional roofing materials such as slate, natural stone or clay products but unlike these materials it is neither heavy nor brittle.
GFRC can be moulded into complex shapes for roofing accessories such as finials, ridges and chimneys. It is non-combustible with a high impact strength and can be used on all types of roof.
Corrugated GFRC sheets, used for industrial and agricultural roofing, are manufactured by automated processes, offering strength and impact performance benefits.
GFRC Walls and Windows
GFRC’s versatility enables it to be used in different ways in the construction and decoration of building walls. In its simplest form, GFRC renders reinforced with alkali resistant glass fibers can be used on a variety of substrates to provide a durable and decorative finish. They may be applied over external insulation as part of a system to upgrade the thermal characteristics of the wall, directly onto blockwork or masonry, or onto metal lath. In all cases the glassfiber reinforcement gives a long-lasting and crack-free performance.
Moulded GFRC components such as window sills, window surrounds, cornices, door portals and columns can add decoration to residential and commercial buildings while also meeting functional needs. Standard prefabricated panels incorporating a choice of surface finish including exposed aggregate, natural stone and brick effect are possible.
GFRC Modular Building
The qualities of GFRC are shown to great advantage in the area of modular building. GFRC panels are light and easily transported but also resistant to damage. Small units such as modular bathrooms or telecommunications equipment housings can be shipped in one piece and rapidly lifted into position. The strength of GFRC is sufficient so that, even in thin skin construction, small modular buildings can be designed without heavy structural frames.
GFRC walls can incorporate thermal insulation if required, while the absence of steel reinforcement can be a benefit in electrical or telecommunications applications.
Aesthetically, the full range of natural and applied finishes, and freedom of design, which characterise GFRC permit solutions to satisfy any architectural requirement.
GFRC is an ideal material for use in renovation.
Thin lightweight panels are easy to fix and minimise the weight imposed on the existing structure. In many cases the opportunity is taken not only to improve the aesthetics of the building but also to improve the thermal and acoustic properties.
GFRC’s ability to be moulded and finished with natural materials means that traditional architectural forms can be maintained when required.
GFRC Foundations and Floors
GFRC can provide practical solutions in the construction of foundations and floors. As permanent formwork under suspended, in-situ concrete floors it can give economic benefits together with excellent appearance. In balcony slab construction, GFRC can provide a pre-finished moulded edge while simplifying construction. On ground floor concrete slabs, insulated GFRC base course and sill units can be incorporated, which contribute to the overall wall insulation performance.
On the construction site, forms of glassfiber-modified concrete can be used in floor screeding, both in relatively thick concrete screeds and in thin self-levelling overlays.
