B2B Trade Supply. Ireland.
Aluminium Window Flashings and Reveal Trims
We press and weld custom aluminium window reveal flashings in Ireland. Our trims are designed to seal window opening boundaries against wind-driven rain.
Silicone is not a building material. Precision over speed.
Project Profile
Dublin Manufacturing Excellence.
We fabricate B2B components at our Dublin facility. Standard 2mm marine-grade alloy ensures durability in coastal environments. Qualicoat powder coating provides RAL-matched weather protection. Fast nationwide delivery in 3 to 5 working days. All measurements verified through the app are built to a 0mm fabrication tolerance.

Precision Reveal Weatherproofing
Window reveals are high risk zones for water ingress, especially in exposed coastal areas of Ireland. We fabricate our window opening flashings from marine grade alloy to prevent corrosion. The pressings seal the junction between the window frame and the external wall structure, protecting the insulation envelope.

Custom Corner Welds and Finishes
Our team folds sill trays, head flashings, and side jamb trims to match reveal dimensions. We pre weld corners in our workshop to create a watertight, structural frame around the window opening. The profiles are powder coated in any standard RAL color.
// Specification Data
Airtightness and Insulation Continuity
Our reveal trims are designed to work with standard airtightness tapes and sealants. By bridging the gap between the frame and structural masonry, they support the building airtight envelope. This prevents cold draughts and minimizes flanking heat loss around window reveals.
// Specification Data
Alloy Purity and Structural Stability
We use high quality 1050A grade aluminium sheets in thicknesses from one point five millimetres to three millimetres. This provides the stiffness required to resist wind loads and mechanical impact while maintaining flat, clean lines along the window reveal margins.

Architectural Powder Coatings
We apply Qualicoat powder coatings in any standard RAL color to ensure UV and weather resistance. The coating protects the metal from oxidation and matches the finish of modern aluminium window frame systems.
Technical FAQ
Frequently Asked Questions
What is the function of a window reveal flashing?
It seals the side jambs and head of the window opening, preventing wind-driven rain from penetrating the insulation layer.
Do you supply sills with matching reveal flashings?
Yes, we coordinate the sizing and color of both the window sills and the surrounding flashings to ensure a watertight installation.
Can these flashings be fitted to external wall insulation systems?
Yes, we design the return legs specifically to cover external insulation edges and provide a clean render stop bead.
What lead times apply to custom window trims?
We fabricate and deliver custom window flashing profiles nationwide within three to five working days.
How do you prevent cold bridging at the window reveal?
Our reveal flashings are isolated from the warm inner structure using EPDM gaskets or thermal closer brackets to break the metal thermal path.
Can we submit window schedule drawings for take off?
Yes, our technical team accepts window schedules and drawing details. We generate take-off dimensions and provide B2B quotes for the complete reveal package.
