Rainwater drainage systems: Ashflow™Ash & Lacy has developed a fully factory bonded system for gutters. This utilises Ashclad-coated steel on the water-carrying surface, and incorporates a proven and tested joint. By insulating the gutter, the amount of energy loss is reduced, as is corrosion and joint leakage. The Ashflow™ insulated gutter system has simple, boltless joints, and is lightweight and durable.
A 15 year guarantee is available, and the gutter system has a lifespan in excess of 30 years.
It has become common practice to simulate the bargeboard flashing profile at the gable end of a building, by incorporating the same feature front face within the design of the eaves gutter detail. The necessity for both bargeboard and gutter to match has encouraged the use of plastisol or PVF2 materials, but with poor weather protection.
The Ashclad fascia-gutter system allows many colour options on the aesthetic face of the gutter, with the long-term weathering benefits of Ashclad complementing the water-carrying surface.
A simple modification to Ash & Lacy’s bonding process when forming the Ashclad laminate allows the gutter, when formed, to hinge and fold into position whilst avoiding any obstructions. This avoids having to use heavy bituminous-type paints to seal the gutters to avoid leaking.
