ALUMASC SKYLINE CILLS & CLOSERS 3 & 4 BEND · COMMON QUESTIONS

Something not answered here? The technical desk takes calls on 0330 0539354
What’s the difference between 3-bend and 4-bend cills and closers?
Three-bend and four-bend cills give extra drip edges for deeper reveals or thicker façades, improving water shedding.
Do 3- and 4-bend cills include built-in drip throats?
Yes, each profile includes a formed drip throat to stop rainwater running back under the sill.
Can 3- and 4-bend cills be powder-coated to match façades?
Yes, all 3- and 4-bend profiles can be finished in any RAL colour for visual continuity.
How are 3- and 4-bend cills sealed at joints?
Seal joints with neutral-cure silicone and secure with supplied colour-matched cover plates.
What are the performance benefits of 3- and 4-bend cills and closers?
Three- and four-bend cills create deeper drips and overhangs, enhancing rainwater control on thick façades. Powder-coated finishes resist chalking, ensuring long-term performance in exposed environments.
How do 3- and 4-bend cills compare in terms of water management efficiency?
Use 3- and 4-bend cills on deep façades to improve drip control. Confirm end-caps are fitted and seal laps properly to maintain weather-tightness.
Which bend type performs better for large reveal depths?
Four-bend cills provide stronger drip control for deep reveals, improving weathering performance.
How can I ensure 3- and 4-bend cills continue to drain properly?
Clear drip throats of debris and check paint integrity each year to maintain effective drainage.
