A
ACETONE
Acetone is a cleaning solvent mainly used with our Fibrelast GRP roofing system to clean the rollers and brushes so that they can be re-used.
ABUTMENT
Abutments are the junctions of a roof surface where it meets a wall, chimney etc..
ASPHALT
Asphalt is a bituminous waterproofing agent used in number of different roofing materials.
B
BARGE BOARD
A bargeboard is a board that is fastened to the projecting gables of a roof to give them strength, protection, and to conceal the otherwise exposed end of the horizontal timbers of the roof to which they were attached.
BATTEN
Roofing battens or battening are used to provide the fixing point for roofing materials. The spacing of the battens on the trusses or rafters depend on the type of roofing material and are applied horizontally.
BUBBLE BUSTER
Also known as consolidating rollers and paddle rollers, these are made for the GRP roofing market that reduce splash back when used with our Fibrelast base resin system.
BINDER
Chopped strand matting is made up of tiny strands of glass bonded by an emulsion binder which breaks down when the Fibrelast GRP roofing resin is applied.
C
CATALYST
Catalyst sometimes called activator or hardener is the chemical that is mixed into the Fibrelast GRP roofing resins and topcoats to start the curing process.
CATALYST DISPENSER
A specially designed method for safely measuring and dispensing catalyst.
COLD ROOF
A cold roof is one where the insulation is laid between the ceiling joists. This means everything above the insulation is colder than the living space and everything below the insulation is warm.
CSM
CSM stands for chopped strand matting and is the fibreglass that is used with the Fibrelast base resin to reinforce the system giving it strength.
COUNTER BATTEN
Wooden strips installed vertically over pitched roofs to which horizontal tiling battens are attached to. They are used to allow rainwater to run off the tiles and off your roof.
D
DORMER
A roofed structure, often containing a window, that projects vertically beyond the plane of a pitched roof. It is also known as rooftop window. Dormers are commonly used to increase the usable space in a loft and to create window openings in a roof plane.
DOWN PIPE
Downpipes carry rainwater from a roof to ground level either directly into a drain or container for green water harvesting.
E
EAVES
The edges of the roof which overhang the face of a wall and, normally, project beyond the side of a building. Eaves form an overhang to push water clear of the walls.
F
FASCIA BOARD
A long, straight board that runs across the lower edge of a roof. The fascia is fixed directly to the lower ends of the roof trusses and usually supports the lower edge of the bottom row of tiles. The fascia board also holds all the guttering in position.
FELT ROOFING
A two or three layers system for boarded flat roofs using either adhesives or hot bitumen or a flame torch. Traditionally this system has been bitumen based although modern polymer products are available which offer better performance.
FLASHING
Traditionally made from lead or zinc, Flashings are used over joints in roof and wall construction to prevent water ingress.
FLAT FLASHING
Supplied in a 20 metre roll, GRP flat flashing is mainly used as a continuous flashing under slates at roof junction.The product has many other uses including gutter linings, parapet wall details and under air conditioning units.
FLAT ROOF
A roof which has a very slight slope, traditionally covered in felt, lead or other waterproof systems.
