ECOSlide PVC-U vertical sliding sash windows supplied with A+ Rated Window Energy Rating as standard


Window Energy Rating

ECOSlide windows have been subjected to Window Energy Rating simulation calculations by an approved British Fenestration Ratings Council (BFRC) simulator.

Thermal Inserts manufactured from 100% recycled PVC-U are inserted in the factory to enhance the thermal performance of the windows. These multi-chambered extruded inserts are much more thermally efficient than traditional steel bars, whilst also being lighter and providing better fixing screw retention during window installation.

Rigorously tested sash windows

Independently tested at a UKAS test house the ECOSlide window has been evaluated in accordance with BS.6375 Part 1 “Performance of Windows: Classification for Weathertightness” against the test assessment methods laid down in BS.5368 and has achieved outstanding results. The figures achieved indicate that the tested Weather Performance Rating for the ECOSlide vertical sliding uPVC sash windows will meet “Severe” weather conditions.

Trickle Vents

Architects, housebuilders and the government are paying increasing attention to ventilation – which is vital to reducing the likelihood of mould and condensation.

To comply with the requirements of Part F of Building Regulations, which governs ventilation, ECOSlide comes with the maximum number of trickle vents as standard.

If implemented poorly, trickle vents can ruin the appearance of a window. However, thanks to an ingenious design, ECOSlide’s trickle vents are concealed, allowing the product to achieve Part L standards without spoiling its heritage aesthetics.
