Product Overview

MACO we design wetherseals together with hardware and thresholds. Weatherseal, hardware, threshold: a proven system of synergy that becomes the ideal solution for your doors and windows.

Can triple-glazed windows with reinforced profiles and multiple locking points still be untight? Yes, they can, if the weatherseal does not work properly. This apparently minor component is made with cutting-edge technology, combining materials with different densities to create complex geometries. It is a barrier to the passage of air which makes the difference: more energy savings improved sound insulation and well being.

In order to have airtight doors and windows and avoid draughts, you need "elastic memory" weatherseals. MACO weatherseals return to their original shape even after the windows or doors have been closed for longer periods of time or in presence of low temperatures. Corners (with 45° and 90° cuts) are just as airtight: the weatherseals are designed so that the terminal ends fit perfectly together or overlap each other leaving no gaps or empty spaces.

A slight resistance in the weatherseal while turning the handle is perfectly normal and indicates that the weatherseal is working properly. Nevertheless, closing a door or window should always be an easy operation. The softness of MACO weatherseals makes for a comfortable closing experience, absorbing any potential deformation in doors and windows over time.

Different materials with different densities, extruded together in a complex geometry designed to close doors and windows perfectly... MACO weatherseals are little technological giants. With a considerable experience in research and development, the use of quality materials, cutting-edge manufacturing processes and computer simulations on how the weatherseals will behave during compression, we can find the perfect combination of material shapes and features.

Each MACO weatherseal is put through a FEA simulation (Finite Element Analysis), showing stress points and their intensity while the door or window is closed. 

The Maco Weatherselas products range consists of: 

  • Window weatherseals 
  • Door weatherseals 
  • Accessories for window and door weatherseals 
  • Floor-door weatherseals 
  • Floor-door weatherseal accessories 

Weatherseals for windows and entrance doors
MACO weatherseals for windows and entrance doors come in many shapes and sizes: based on your door or window profile, our expert consulants will help you find the right sash, frame or overlap weatherseal.

Weatherseals for HS
In order to allow the lift&slide systems (HS) to slide without friction and avoid the passage of air or water, you need weatherseals with a special geometry and high quality materials. MACO weatherseals enclose the whole sliding system without interruptions thanks to their welded corners.

Weatherseals for interior and front doors
Weatherseals that run along the three sides of an interior door frame, muffling sounds for improved comfort.

Floor-door weatherseals
The gap between the door and the floor can be closed with a rise and fall system: when the door is open, the weatherseal is hidden within a metal profile; when the door is closed, the weatherseal drops to prevent draughts and noise. It is an ideal system to make reinforced doors airtight or for soundproofing hotel doors.

The use of fine materials determines the quality of a weatherseal and ensures its softness and elasticity over time. MACO weatherseals are made with high-quality raw materials: our products are compatible with all kinds of paint, working well at both low and high temperatures and maintaining their resistance over time.

  • Expanded theromoplastic elastomer (TPE) weatherseas (TE)
  • Compact TPE weatherseals (TC)
  • EPDM weatherseals (EE, EC)
  • Compact silicone weatherseals (SC)
  • Expanded silicone weatherseals 
  • Compact thermoplastic weatherseals (PC)

To know and compare weatherseal performance at a glance, it is useful to learn how to read the codes with 6 characters classifying them according to the EN 12365-1:2003 standard. So we can see right away that a W33264 is better than a W38221. Each MACO weatherseal is provided with a technical sheet where you can find the code.
