Class A Window
Weather resistance and long-term durability.
It guarantees an outer wall thickness of 3 mm (± 0.2 mm) according to DIN EN 12608. Under these European standards, PVC profiles are classified into three categories regarding weather resistance and long-term durability. The Class A rating of the ADF Premium window indicates the highest level of quality and durability, offering homeowners comfort, safety, and long-term savings.
Passive Houses
High indoor comfort with minimal energy consumption.
Passive houses are highly energy-efficient buildings that provide superior indoor comfort while using minimal energy. To achieve passive house certification, the selected windows must be energy-efficient and feature triple glazing with a Ug value of 0.5 W/m²K and a total heat transfer coefficient Uw ≤ 0.8 W/m²K. The lower this coefficient, the higher the thermal efficiency of the window. The performance of the ADF Premium window meets the requirements for passive houses.
Energy performance:
thermal transmittance up to Uw = 0.75 W/(m²K)
The ADF Premium window has a thermal transmittance coefficient of up to Uw = 0.75 W/(m²K). This coefficient defines the degree of heat transfer and therefore the thermal insulation performance of the window. The lower the Uw value, the better the insulation and, consequently, the higher the performance of the window.
Acoustic comfort:
sound insulation up to 47 dB
The ADF Premium window provides sound insulation of up to 47 dB. The level of soundproofing is essential to reduce external noise and create a quiet, comfortable indoor environment. This feature is measured in decibels (dB), with higher values indicating superior acoustic performance. A soundproofed window is crucial in urban areas or near major noise sources such as busy streets, railways, or airports.
Security:
burglary protection up to RC 2
The ADF Premium window offers burglary protection up to RC 2. This refers to the window’s ability to resist forced entry attempts and is classified according to European standards. An RC 2-rated window must withstand break-in attempts by an opportunistic intruder using simple tools such as screwdrivers, pliers, and wedges for at least 3 minutes. The window features multiple anti-burglary locking points which, together with their distribution on the frame, provide enhanced resistance against forced entry.
Triple or double insulating glazing
with DuraTherm warm spacer
The glazing unit of the ADF Premium window can be 48 mm (triple glazing) or 36 / 28 mm (double glazing). Since glass makes up around 80% of a window’s surface, the thermal and acoustic insulation properties largely depend on the glazing quality. Triple glazing is made of three panes of glass forming hermetically sealed chambers filled with inert gas (argon) and joined with a spacer bar. The spacer seals the unit and prevents heat transfer between the interior and exterior. Therefore, it is essential that the spacer material has the lowest possible thermal conductivity. ADF windows come standard with the DuraTherm “warm” spacer.
3 sealing gaskets.
Enhanced airtightness!
The sealing gaskets prevent air and water vapor from passing through the gaps between the sash and the frame. They help reduce heat loss through the windows, thus improving the energy efficiency of the home (preventing unwanted heat transfer, keeping warmth inside in winter and coolness in summer). The ADF Premium window is designed with 3 sealing gaskets to ensure superior thermal insulation.
76 mm.
Large profile depth.
The 76 mm profile depth of the ADF Premium window represents the distance measured from the inner to the outer face of the frame. Also referred to as the window chassis, profile depth is a visible element that directly affects the window’s energy efficiency. A greater profile depth allows the installation of thicker glazing units, which improves the thermal performance of the window.
1.5 mm reinforcement.
Standard galvanized steel stiffening
Reinforcement involves inserting steel profiles into the PVC profiles to stabilize them, ensuring superior window strength. The reinforcement consists of a specially shaped galvanized steel profile inserted into the reinforcement chamber and fixed with self-tapping screws. For the ADF Premium window, we use 1.5 mm steel reinforcement as standard (2 mm optional).
