Secondary Glazing Plastic Options: A Comprehensive Guide to Improving Insulation

In an era where energy effectiveness and rising utility expenses are at the forefront of homeowners' issues, discovering ways to insulate homes efficiently has ended up being a priority. While replacing whole window systems with double or triple glazing is a common option, it can be prohibitively pricey and is often not allowed in noted structures or sanctuary. This is where secondary glazing works as a practical, affordable alternative.

Secondary glazing involves setting up an extra pane of glass or plastic inside an existing window. While glass was once the basic product, developments in polymers have actually made plastic choices significantly popular. This guide checks out the various secondary glazing plastic alternatives, their advantages, and how they compare to one another.


Why Choose Plastic Over Glass?

Before diving into specific products, it is important to comprehend why a property owner or center supervisor might select plastic rather of conventional glass for secondary glazing.

  1. Light-weight Nature: Plastic sheets are considerably lighter than glass. This makes them simpler to deal with during DIY installations and locations less strain on existing window frames.
  2. Security and Impact Resistance: Many plastic choices are virtually unbreakable. In families with kids or in locations susceptible to high winds, the unbreakable nature of plastics like polycarbonate offers peace of mind.
  3. Thermal Insulation: Plastics are naturally much better insulators than glass. They have lower thermal conductivity, implying they are more effective at avoiding heat from leaving through the window.
  4. Relieve of Customization: Unlike glass, which requires expert cutting and toughening, plastic sheets can frequently be cut to size utilizing fundamental workshop tools.

Secret Plastic Materials for Secondary Glazing

There are 3 primary kinds of plastic utilized for secondary glazing: Acrylic, Polycarbonate, and PETG. Each has special qualities that make it ideal for various environments.

1. Acrylic (typically called Perspex or Plexiglass)

Acrylic is perhaps the most typical plastic utilized for secondary glazing. It is prized for its exceptional clarity and aesthetic resemblance to glass.

  • Clearness: Acrylic is clearer than glass, enabling more light to go through.
  • UV Resistance: It is naturally resistant to UV light, suggesting it will not yellow or become brittle when exposed to direct sunshine over many years.
  • Weight: It is around 50% lighter than a glass pane of the exact same thickness.
  • Restriction: It is more fragile than polycarbonate and can break if mauled or drilled incorrectly.

2. Polycarbonate (frequently referred to as Lexan)

Polycarbonate is the "heavy-duty" option of the plastic world. It is often utilized in high-security environments or where severe sturdiness is required.

  • Strength: Polycarbonate is approximately 250 times more powerful than glass and is practically solid.
  • Fire Rating: It has excellent fire-resistant residential or commercial properties, often carrying a Class 1 fire ranking.
  • Versatility: It is more flexible than acrylic, making it much easier to fit into a little unequal frames.
  • Limitation: It is more prone to scratching than acrylic and is normally more expensive.

3. PETG (Polyethylene Terephthalate Glycol)

PETG is a thermoplastic that sits between acrylic and polycarbonate in terms of performance.

  • Ease of Use: It is really simple to make and does not need customized drill bits.
  • Food Safe: While not always pertinent for glazing, its chemical resistance makes it resilient against severe cleaner.
  • Restriction: It does not have the same level of UV stability as acrylic, making it more fit for windows that do not get constant, direct sunlight.

Setup Methods for Plastic Secondary Glazing

The efficiency of secondary glazing depends heavily on the setup approach used. Because plastic is lightweight, several non-permanent choices are offered.

Magnetic Strip Systems

This is the most popular DIY technique. 2 magnetic strips are used: one is followed the window frame and the other to the border of the plastic sheet.

  • Pros: Easy to remove for cleansing or throughout the summer season.
  • Cons: Not as airtight as fixed systems; magnets can lose strength over lots of years.

Clip and U-Channel Systems

This involves screwing small plastic clips or a "U-channel" track around the window frame. The plastic sheet is then slotted into location or held by the clips.

  • Pros: Provides a more protected hold than magnets.
  • Cons: Requires drilling into the window frame or surround.

Screw-on Fixed Systems

For maximum insulation and draught proofing, the plastic sheet can be screwed directly to the frame utilizing color-coded washers and screws.

  • Pros: The most airtight and long-term option.
  • Cons: Difficult to eliminate; needs noticeable holes in the window frame.

Maintenance and Care

To make sure the durability of plastic secondary glazing, particular upkeep procedures need to be followed. Unlike glass, plastics are delicate to certain chemicals.

  • Cleaning: Never use glass cleaners consisting of ammonia or alcohol (like Windex), as these can "trend" (produce small fractures) or cloud the plastic. Rather, utilize  notting hill secondary glazing windows  with a mild dish soap and a soft microfiber fabric.
  • Fixed Reduction: Plastics can attract dust due to static electrical power. Utilizing specific anti-static cleaners can help keep the panels clear for longer.
  • Scratch Prevention: When cleaning, prevent circular motions. Use long, horizontal or vertical strokes to minimize the visibility of any minor abrasions that might happen.

The Benefits of Plastic Glazing: At a Glance

  • Sound Reduction: Creates an acoustic barrier that can minimize external noise by as much as 50-70%.
  • Condensation Control: By producing a thermal break, it avoids warm air from striking cold glass, considerably minimizing interior condensation.
  • Expense Savings: Lower initial product cost and lowered heating bills result in a high roi.
  • Conservation: Ideal for historic homes where initial windows must be preserved.

Often Asked Questions (FAQ)

Does plastic secondary glazing yellow gradually?

If high-quality Acrylic (Perspex) is utilized, it will not yellow for at least 10-- 20 years. Requirement Polycarbonate might yellow if it does not have a UV-resistant coating, so it is essential to purchase "UV-stabilized" sheets for south-facing windows.

What density should I pick for the plastic?

For a lot of domestic windows, a thickness of 2mm to 4mm is sufficient. 2mm is extremely light however might "bow" in larger windows; 3mm or 4mm provides more rigidity and much better sound insulation.

Can I still open my windows?

If a magnetic or clip-on system is used, the panel can be removed rapidly to enable ventilation. If irreversible ventilation is required, "moving" secondary glazing systems are available, though these normally require an expert installer.

Will plastic glazing stop all condensation?

While it considerably lowers condensation by keeping the inner surface area warmer, it may not eliminate it entirely if there are existing dampness issues in the space or if the seal on the secondary glazing is not airtight.

Can I cut the plastic myself?

Yes, the majority of plastics can be cut with a fine-toothed saw or a jigsaw. Acrylic can also be "scored and snapped," though this requires practice to avoid rugged edges.


Secondary glazing using plastic choices uses a flexible, efficient, and budget-friendly method to enhance the thermal and acoustic performance of a structure. Whether choosing the crystal-clear surface of Acrylic or the indestructible nature of Polycarbonate, property owners can take pleasure in a warmer, quieter environment without the disturbance and expenditure of full window replacement. By choosing the right product and installation technique, it is possible to attain professional-grade insulation results through basic DIY improvements.
