SAM Cadenza II window frames are largely prefabricated assembled

The power of together

On the Italiëlaan in Zoetermeer, a new housing project for young people, starters and people moving on is being built: SAM Cadenza II. The project consists of a low-rise section and a tower of about 70 meters high. While the low-rise section provides space for 60 youth housing units with a communal terrace, the tower will house 20 owner-occupied apartments and 141 free-sector rental apartments. The building will also contain a parking garage with space for shared cars and bicycles. The first floor will provide space for commercial and social facilities. All apartments meet the BENG requirements and are connected to a heat and cold storage system and solar panels. In addition, they have aluminum window frames with triple glazing.

Commissioned by Bouwcombinatie SAM Zoetermeer (Ter Steege Bouw Vastgoed Delft and Dura Vermeer Bouw Zuid West B.V.) and in collaboration with Moke Architects, Facédo Geveltechniek is supplying and fitting 823 aluminum window frames for SAM Cadenza II, including water layers. No fewer than 628 integrated French balcony screens made of glass serve as fall protection for this, says project manager Frank van den Heuvel. "By integrating the glass balcony screens into the frame profile, maximum transparency, more light and a flat frame appearance are ensured." 

SAM Cadenza II is named after architect and urban planner Samuel van Embden, on whose drawing board Zoetermeer was born in 1963. Moreover, the name SAM stands for "together": working together, bringing together different target groups and working together; for each other and for society.

Partnership

'Together' also refers to Dura Vermeer's strategy of working with a strong network of established partners. Transparent, predictable and equal. After all, this creates trust, combats waste and ensures smarter solutions. One of the regular partners is Facédo, with whom a national framework agreement was signed in October 2024. "Following on from high-profile projects such as De Koploper in Gouda, Hefkwartier in Rotterdam and De Kroon in Zoetermeer, we started the engineering of approximately 4,000 m2 of aluminum window frames for SAM Cadenza II just before the 2024 construction period," says Van den Heuvel. "At the basis of the window frames is the RT72 Reflex I window and door system. The window frames are anodized in the color C33 (bronze), have a Uw-value of 1.0 W/m2K and are equipped with triple glazing with a U-value of up to 0.6 W/m2K. The window frames have a wind and water tightness of 480 Pa. Including multi-point locks and adjustable hinges and locks, the frame elements also comply with air tightness class 4; the highest classification according to NEN-EN 12207."

Fire resistant window frames

For the armpit area of SAM Cadenza II, Facédo made fire-resistant window frames, with a fire resistance of 30 minutes in both directions. And fire-resistant window frames with 30 minutes of resistance were also used in the high-rise building to slow fire spread through the facade.

Prefabrication

In November 2024, Facédo started assembling the window frames. "A nice feature of this project is that we only assemble and glaze the frames of the plinth on site in Zoetermeer," Van den Heuvel says. "The frames of the tower are built into the timber frame elements in our prefab factory in Velp and then transported just-in-time to the construction site, where HSB supplier WEBO assembles the elements without scaffolding. Because the HSB elements for the low-rise are fitted with ceramic stone strips, these frames are built into WEBO's HSB factory. Indeed, because of the fragility of the stone strips, minimal transport movements are desired."

High quality, stable conditions

A major advantage of prefabrication is that work can be done in a controlled way and under the best labor and climate conditions, Van den Heuvel says. "This allows us to control quality even better. Mutations are recorded in advance and the elements transported to the construction site no longer contain break glass. An important incentive under the Building Quality Assurance Act (Wkb)." In addition, prefabrication leads to fewer transport movements to and shorter lead times on construction, he says. "It also requires significantly less storage space and personnel on the construction site."

Completion of SAM Cadenza II is scheduled for late Q1 2025, with the last homes expected to be delivered in early Q4 2025.
