PRODUCT FAMILIES
Start with the Opening. Refine the Complete System.
Product selection begins with how the opening should operate, then develops around visible sightline, panel size, glass, hardware, climate and required performance. ALTOP coordinates these decisions as one project package.
Windows
Casement, sliding, awning / top-hung, tilt & turn and fixed window systems for ventilation, daylight, views and building-envelope performance.
Doors
Slim sliding, lift & slide, bifold, hinged and French door systems for entrances, terraces and expansive architectural openings.
Slim Systems
Minimal-frame window and door directions developed around reduced sightlines, large glass panels and clean contemporary architecture.
Performance Coordination
Thermal, structural, air and water, acoustic, glazing and installation requirements reviewed together with the selected opening type.

FOR ARCHITECTS & DESIGNERS
Specify More Than a Product Name.
For useful system selection, share plans, elevations, window and door schedules, opening sizes, project location and target performance. This allows the product direction to be reviewed against the real architecture rather than selected from appearance alone.
Available technical inputs may include sightline priorities, glass build-up, U-value or SHGC targets, wind exposure, acoustic requirements, threshold conditions, hardware preferences and installation interfaces.
PROJECT-LED PRODUCT SELECTION
One Catalogue Cannot Define Every Project.
ALTOP matches product families with project conditions, qualified manufacturing resources and the technical information available for the selected system. Final dimensions and performance values are confirmed against the actual configuration before quotation.
