Consisting of two phases, this system combines innovative wood repair techniques with a unique draught-proofing system to breathe new life into wooden windows and doors.
The initial phase of the Ventrolla system focuses on renovating the windows, treating the wood, and restoring their functionality. The key component in this phase is the Ventrolla Wood Repair System (VR90), a specially formulated two-part epoxy resin designed to revitalise and reinforce wooden windows and doors. Some notable benefits of the VR90 Wood Repair System include:
During the renovation process, Ventrolla conducts a thorough inspection and survey of all windows, assessing their condition and identifying areas of decay. The steps involved in the renovation process include:
The second phase of the Ventrolla system focuses on upgrading the performance of wooden windows by installing the Ventrolla Perimeter Sealing System (VPSS). The VPSS is specifically designed to be compatible with windows and doors of any shape or size. Its installation enhances the windows’ performance without compromising their appearance or character. Key benefits of the Ventrolla Perimeter Sealing System include:
The installation process of the Ventrolla Perimeter Sealing System involves the use of Weatherfin two-piece parting beads with a pile carrier fitted into a U-section. These sealing systems conform to relevant standards, including BS 7386: 1997, BS EN 12207: 2000, and BS6375-1: 2009 (Class 3). They are manufactured using water-repellent and UV-stabilized multifilament polypropylene yarn. Additionally, the sealing system can be supplied in various colours, allowing for customisation (additional cost may apply).
During the installation, the Ventrolla team ensures that the sealing system is applied to the top of the box, mid rail, bottom rail, parting bead, and staff beads, creating a comprehensive seal around the window or door. The sashes are carefully weighed and adjusted to ensure proper balance and smooth operation. Any exposed or bare wood is treated with a white acrylic primer to provide protection, while the final decorative painting is left to be done by others.
Independent testing has validated the effectiveness of the Ventrolla Perimeter Sealing System. The system has achieved the highest requirements of BS6375-1:2009, Class 3, ensuring its durability and performance under testing conditions of up to 600 Pa. Furthermore, the VPSS contributes to improved energy efficiency, with potential energy rating improvements of up to 30%. The system also reduces air change rates to a remarkable 0.4 air changes per hour, resulting in enhanced thermal insulation. Additionally, the Ventrolla system has been independently tested and proven to provide noise reduction levels within the range of 6 to 10 dB(A).
The sash removal system (SRS) is discreetly mounted in the side of the sash, allowing safe and easy removal of both the upper and lower sashes, to therefore give free access to the window box frame, and is not visible either internally or externally during the normal operation of the sash window.
The Ventrolla system has garnered recognition and trust from esteemed organisations dedicated to the preservation of historic buildings and architectural heritage. English Heritage, Historic England, Historic Scotland, and Cadw have all recognised the Ventrolla system for its ability to restore and upgrade wooden windows while maintaining their historical and architectural significance.
One common misconception is that double glazing alone provides effective sound insulation due to the presence of two panes of glass. However, the truth is that it is the seal that plays a crucial role in soundproofing. In this regard, the Ventrolla Perimeter Sealing System (VPSS) is designed to offer comparable sound insulation, as illustrated in Diagram B. By effectively sealing the windows, the VPSS helps reduce noise transmission, creating a more peaceful and serene indoor environment.
In addition to the numerous benefits of the Ventrolla system, it also addresses environmental concerns. By prioritising the retention of the original material, the Ventrolla system significantly reduces its carbon footprint when compared to window replacements. Here are some notable environmental facts:
When you select Ventrolla, you’re not just restoring the attractiveness and functionality of your windows; you’re actively choosing to support a greener and more sustainable future. With their expertise, you can experience the advantages of energy efficiency, decreased environmental impact, prolonged lifespan, and the preservation of historical significance.
