EVS is a whole new way to protect and upgrade your character windows. The double glazed insulated panel provides a triple glazing result by retaining your existing character glass. The EVS panel increases protection against damaging weather and sun and preserves your window with minimal visual impact on the character of your home. Not only is EVS less invasive, it is also less expensive to install compared with the traditional replacement double glazing which requires invasive deconstruction and expensive re-glazing with only double glazing performance EVS can be installed by our fully trained team or by competent DIY home owners.

RetroWood is the Agent for EVS Double Retro Glazing that uses advanced uPVC glazing beads to provide a more durable retro glazing system.
The key feature of the EVS Double Retro Glazing is the Aerated PVC profile that provides a strong and low profile bead that secures the glass into its position. The PVC profile integrates a rubber (EPDM) seal that provides a durable seal and a sharp looking finish. The PVC can be cut, pinned and painted like timber but unlike timber it wont swell up with moisture or bend, twist or split after it has been installed making for a more durable and long lasting solution.
The EVS Double Retro Glazing system follows industry standards when it comes to specifying glass and securing the glass with suitable glazing blocks and edge clearances. Where EVS stands out from the others is the design of the glazing beads follows the EVS method of using air vents to provide air movement around the installed glazing panel. Trapped moisture very rarely flows out from the drain holes unless there is an excessive amount of moisture getting into the cavity, so air vents work better to remove moisture that would otherwise cause rot or panel failure. The PVC and EPDM rubber seals also serve to provide a long lasting bead seal.
RetroWood is the Agent for EVS Triple Retro Glazing that uses advanced uPVC glazing frames that protect existing character windows as well as providing them with leading insulation.
Triple Retro Glazing is a whole new way to enhance existing windows that maximize the insulation and protection while reducing the time and invasive installation process. The EVS panels can be fitted with most types of glass combinations and can be tailored to the customer's requirements and budget. Most commonly Low-e Glass is used to achieve the high performance insulation, whereas standard glass can provide more heating from the sun.
The key to the EVS technology is using thermal pumping as a way to remove trapped moisture that collects between the existing and new panel. As the panel heats up during the day, the warm air mobilizes the trapped moisture which rises to the top of the panel where it is pumped out through the top vents by the action of heat expansion. As the panel cools down, the opposite happens and it contracts and draws in external dryer air.
The vents use the unique qualities of Bentonite clay that can absorb moisture from the air, but unlike other synthetic desiccates Bentonite clay can release the moisture at low temperatures allowing the moisture to be captured in cool temperatures and released when the panel warms up.
EVS has developed this unique system to ensure any trapped moisture can be released and not build up between the panels and cause fogging. The process is called thermal pumping that uses the cycle of warm and cold to breath in cool dry air and expel warm moist air and promote a dry cavity between the existing glass and new glass panel. The panel is clipped to the surface of the existing timber sash and is sealed and painted so that it integrates into the style of the existing joinery. It is recommended that opening panels are also fitted with EVS Draught Stop to achieve the best performance result
RetroWood is the Agent for EVS Draught Retro Seals that use advanced uPVC profiles to provide a more durable and effective draught stop system.
Older homes with character timber windows that can look nice, but have gaps that reduce their effectiveness. There are many gap filling foam seals on the market, they are only short term solutions. EVS has developed a range of unique, easy to fit, retro seals made from aerated PVC that look and feel like timber. Pre-finished in white or timber and fitted with quality seals for a durable and lasting result that meets the requirements of the Healthy Home Standards.
