Description
Ventrolla Casement Windows combine the timeless elegance of traditional design with the benefits of modern energy efficiency and performance. These bespoke timber windows are perfect for both new-build and restoration projects, offering a versatile solution for any building type. With superior weatherproofing, acoustic insulation, and a smooth, durable operation, Ventrolla Casement Windows are an ideal choice for enhancing both the aesthetics and functionality of residential, commercial, or heritage properties.
Purpose made vacuum or double glazed windows for replacing original single glazed timber windows, giving a vacuum or double glazed solution without major disruption to the property.
Construction:
The windows are manufactured using traditional carpentry methods. Double glazed units include ‘through solid’ glazing bars, which help to retain the windows authentic feel and look. Another main feature of the slim glazing unit is the reduced sightline of the spacer bar between the two panes of glass.
Vacuum glazed windows use the latest glazing technology to upgrade timber windows for increased energy efficiency. Applied glazing bars ensure an authentic look whilst enabling the delivery of a low U-value.
Ventrolla Perimeter Sealing System (VPSS):
Includes unique VPSS draught proofing system which has been tested to BS 6375-1, Class 3, and withstand 71 mph winds. The system is fitted by routing grooves into the mid-rail and bottom-rail of the sashes, or within the inner edges of casement windows, to which a pile carrier is fitted and the appropriate size of weatherfin pile installed. New parting beads and staff beads are fitted that also incorporate the weatherfin pile, creating a fully draught-proofed window.

- Minimum disruption and redecoration to the property.
- Perimeter sealing system tested to BS 6375-1 (withstands 71 mph winds).
