What is Secondary Glazing Secondary glazing involves the setup of an extra pane of glass or acrylic held within a discrete frame to the internal side of an existing window Unlike double glazing where the 2 panes of glass are sealed together as a single unit secondary glazing functions as a different system that sits a few inches far from the primary window
When framed in uPVC these systems provide an additional layer of insulation The gap developed between the 2 panes serves as a buffer substantially reducing heat loss and dampening sound waves
Why Choose uPVC for Secondary Glazing uPVC is a favored product in the building market for numerous factors When utilized in secondary glazing it provides specific advantages over aluminum or timber alternatives
Thermal Efficiency Plastic is a naturally bad conductor of heat Unlike aluminum which can feel cold to the touch and transfer heat out of a space uPVC frames help keep heat Low Maintenance uPVC does not rot rust or peel It requires nothing more than an occasional wipe with a wet cloth to maintain its look CostEffectiveness Generally uPVC systems are more budget friendly than custom aluminum systems making them available to a larger variety of house owners Visual Integration Most modernday properties currently feature white uPVC primary windows Adding a uPVC secondary system ensures a smooth visual match Types of uPVC Secondary Glazing Systems There is no onesizefitsall technique to secondary glazing The option of system depends upon the function of the initial window and the specific requirements of the resident

Best for Windows that only require to be accessed sometimes for cleaning or to operate the primary window Benefits Provides a tidy look with minimal hardware noticeable 3 Horizontal and Vertical Sliders These systems imitate the movement of the primary windows Horizontal sliders move from side to side while vertical sliders frequently called Sash secondary glazing move up and down
Best for Sash windows or large casement windows where routine access to the external window is required Benefits High functionality and simple operation the uPVC tracks ensure a smooth moving motion 4 Hinged Units Hinged uPVC secondary glazing opens like a door either swinging inward or up
Best for Windows where a complete clear opening is needed or for fire escape exits Benefits Allows for maximum ventilation when needed but supplies a tight seal when closed Technical Comparison of Secondary Glazing Materials While this post focuses on uPVC it is practical to see how it sits within the wider market

Thermal Insulation and Draft Exclusion Older windows especially lumber sash windows are notorious for drafts The uPVC frame of a secondary unit creates a physical barrier that avoids cold air from getting in the home This lowers the work on central heater causing lower energy expenses and a lowered carbon footprint
Condensation Reduction Condensation occurs when warm damp air hits a cold surface the window glass By including secondary glazing the interior pane remains closer to space temperature level which significantly lowers the likelihood of moisture accumulation and subsequent mold growth on window sills
Boosted Security Including another layer of glazing provides an additional deterrent for burglars Breaking through 2 different panes of glass in two different frames is significantly more difficult and noisier than breaking through a single unit
Installation Professional vs DIY uPVC secondary glazing is offered in both professionalgrade bespoke systems and DIY kits
Bespoke Professional Installation A professional determine the windows to the millimeter The uPVC frames are manufactured to fit completely making sure the greatest possible thermal and acoustic performance This is suggested for large homes or complex window shapes DIY uPVC Kits Many suppliers offer cuttosize uPVC trim and glazing panels generally acrylic or polycarbonate This is a popular option for budgetconscious property owners While efficient the seal might not be as airtight as professionally fitted magnetic or screwin systems Summary of Pros and Cons Pros
Significantly increases the Energy Performance Certificate EPC rating of a home Much less expensive than changing original windows Keeps the external appearance of the home essential for listed structures uPVC is resistant to wetness making it ideal for kitchen areas and bathrooms Provides superior soundproofing compared to basic double glazing Cons
uPVC frames can be slightly bulkier than streamlined aluminum profiles Creates an additional surface area to clean four sides of glass rather of 2 Can restrict access to the primary window if the wrong opening design is chosen Often Asked Questions FAQ Q Can I install uPVC secondary glazing in a sanctuaryA Generally yes Since secondary glazing is an internal alteration and does not change the external appearance of the building it normally does not require planning approval Nevertheless it is always recommended to contact the local planning authority
Q Does secondary glazing cause condensation between the panesA If set up properly it must really reduce condensation However if the main window is not airtight some moisture can get trapped Professional systems frequently include little vents or desiccant crystals to manage air moisture within the gap
Q Is uPVC better than aluminum for soundproofingA The material of the frame has less effect on noise than the thickness of the glass and the size of the air space Nevertheless uPVCs density helps moisten vibrations somewhat much better than a standard nonthermally damaged aluminum frame
Q Can I still open my windows for ventilationA Yes offered you select a sliding or hinged uPVC unit These are designed to permit full access to the initial window manage and opening mechanism
Q What is the perfect gap in between the two windowsA For heat insulation a gap of 20mm to 100mm is efficient For maximum soundproofing a broader gap of 100mm to 200mm is recommended
