Exceptional energy efficient windows
Sunfold Systems offers exceptional U-values with its latest Internorm window products.
The energy efficiency of our windows is paramount to both us and our customers, we therefore have two particularly innovative window styles available that achieve both outstanding efficiency levels and aesthetic appeal.
Both the KF 220 aluminium & UPVC window and the HF 210 aluminium & timber windows achieve exceptional U-values. Especially as legislation states that windows have to comply to a U-value rating of 2.0W/m²K to meet building regulations; it’s impressive to see that the KF 220 and the HF 210 can achieve U-values as low as 0.67 W/m²K!
The innovative glass sash of the KF 220 gives the impression of fixed glazing, however it is in fact an openable window. Whether in classic white UPVC or with aluminium attachment clad, the narrow, square edged window frame underlines the reduced architecture of the design ‘Studio’ style. Three-sided rendering of the frame fulfils your dreams of almost frameless glass architecture. I-tec glazing ensures excellent stability, thermal insulation and security by all around gluing of the glass pane.
The HF 210’s aluminium attachment clad protects the timber from all weather conditions. The square-edged aluminium profiles of frames and windows can be designed in many colours and facilitates countless design possibilities for the exterior facade. I-tec glazing, the gapless all around gluing of the glass pane, offers excellent stability, burglary protection as well as thermal insulation and sound reduction. Concealed hardware on the inside of the HF 210 ensures a continuous, comfortable timber surface.
Exact U-values will depend on the size of the window panels, the type of frame, sealants used and also glazing and glazing coatings. To find out more about our Energy Efficient Windows please contact us or Request a Quote.
