10 Quick Tips About Secondary Glazing Acrylic Options

Improving Home Efficiency: A Comprehensive Guide to Secondary Glazing Acrylic Options

In a period where energy expenses are increasing and environmental sustainability is a primary issue for homeowners, the search for reliable insulation options has heightened. While double glazing is typically touted as the gold requirement for window insulation, it is not constantly a feasible choice due to high costs, structural constraints, or the limiting guidelines surrounding heritage and noted structures. This is where secondary glazing functions as a versatile and cost-efficient alternative.

Particularly, acrylic secondary glazing has actually become a frontrunner for those seeking a balance in between efficiency, cost, and ease of installation. This post explores the different acrylic alternatives offered, the benefits of picking this product, and how it compares to other glazing alternatives.


What is Acrylic Secondary Glazing?

Secondary glazing includes the setup of an additional pane of glass or plastic inside an existing window frame. Unlike full window replacement, this method protects the original outside window while developing an insulating layer of air between the 2 panes.

Acrylic, clinically called PolyMethyl Methacrylate (PMMA), is a transparent thermoplastic frequently utilized as a lightweight and shatter-resistant option to glass. It is often marketed under brand names such as Perspex or Plexiglass. Because it is extremely adaptable and supplies exceptional clarity, it has ended up being the favored material for DIY secondary glazing jobs and expert retrofitting alike.

The Different Types of Acrylic Sheets for Glazing

When choosing acrylic for secondary glazing, it is crucial to understand that not all sheets are made equally. The choice of material effects the window's longevity, clarity, and insulation homes.

  1. Extruded Acrylic: This is the most economical choice. It is made by pushing the plastic through a kind. It has a lower melting point and is simpler to laser-cut, making it perfect for standard domestic window sizes.
  2. Cast Acrylic: Known for its remarkable quality, cast acrylic is made by putting liquid ingredients into a mold. It provides better thermal stability and is less most likely to scratch or warp in time compared to extruded versions.
  3. UV-Resistant Acrylic: Standard acrylic already uses some UV defense, however specialized UV-resistant sheets are created to obstruct as much as 99% of hazardous rays, preventing the fading of interior carpets, furnishings, and art work.
  4. Abrasion-Resistant Acrylic: This type features a hard-coated surface area that protects the sheet from scratches and chemical damage, ensuring the glazing stays clear even after years of cleaning.

Key Benefits of Acrylic Secondary Glazing

The shift toward acrylic secondary glazing is driven by numerous practical benefits. For numerous homeowners, the choice is based on 3 primary elements: thermal performance, acoustic insulation, and expense.

1. Thermal Efficiency and Heat Retention

Acrylic is a naturally insulating material. When set up as secondary glazing, it creates a fixed air pocket that functions as a thermal barrier. This reduces "U-values" (the rate of heat transfer), meaning the home stays warmer in the winter and cooler in the summer season. This reduced reliance on heating and cooling systems causes considerable decreases in annual energy costs.

2. Acoustic Insulation (Noise Reduction)

For residents living near busy roadways, airports, or rail lines, noise contamination is a substantial issue. Acrylic is frequently denser than thin glass panes discovered in older windows. When a gap of around 100mm to 150mm is preserved between the main window and the acrylic sheet, the system can reduce external sound levels by up to 80%.

3. Safety and Durability

Acrylic is practically unbreakable. Unlike glass, which can get into dangerous fragments upon effect, acrylic is extremely resistant to require. This makes it a perfect choice for homes with kids or animals. Furthermore, its light-weight nature puts less tension on existing window frames and makes the setup procedure much safer for a single person to handle.

4. Looks and Preservation

One of the greatest benefits for owners of historic or noted properties is that acrylic secondary glazing is "discreet and reversible." It does not alter the external look of the structure, satisfying most local planning authorities. The high transparency of acrylic guarantees that the view remains unobstructed.


Installation Methods for Acrylic Glazing

One reason acrylic is so popular is the range of setup techniques readily available, ranging from short-lived seasonal fixes to irreversible components.

  • Magnetic Strip Systems: This is the most typical DIY approach. Magnetic tape is used to the window frame and the edge of the acrylic sheet. This allows the pane to be quickly gotten rid of for cleansing or throughout the summertime when ventilation is needed.
  • Plastic Clips and Turnbuttons: Small clips are screwed into the window surround to hold the acrylic sheet securely in location. This is a safe approach that still allows for seasonal removal.
  • Screw-in Frames: For a more long-term option, acrylic sheets can be installed within a slim aluminum or PVC frame that is then screwed into the window expose.
  • Adhesive Tape: While the cheapest alternative, using high-bond double-sided tape is typically dissuaded for long-term usage as it makes removing the sheet for window upkeep tough.

Upkeep and Care

To make sure the durability of acrylic secondary glazing, correct maintenance is essential. Acrylic is softer than glass and can be scratched if dealt with improperly.

  • Cleansing Agents: Never use window cleaners consisting of ammonia or alcohol (like Windex), as these can "fad" (create small cracks) or cloud the surface area of the acrylic. Rather, utilize lukewarm water with a mild dish soap.
  • Cloth Selection: Only use soft microfiber cloths. Paper towels or abrasive sponges can leave great scratches that dull the openness in time.
  • Static Management: Acrylic can draw in dust due to static electrical energy. Using Windows And Doors R Us -static cleaner particularly created for plastics can help keep the sheets cleaner for longer.

Often Asked Questions (FAQ)

Q: Does acrylic secondary glazing cause condensation?A: Secondary glazing is in fact created to decrease condensation on the primary window by keeping the inner surface warmer. However, if the seal isn't ideal, some moisture might get caught. Including a little sachet of desiccant or guaranteeing the space is well-ventilated can reduce this.

Q: Is acrylic or polycarbonate much better for windows?A: For secondary glazing, acrylic is normally much better because it is more UV-resistant and offers greater clarity. Polycarbonate is stronger but is more vulnerable to scratching and can yellow gradually if not treated with expensive coverings.

Q: What density of acrylic should I utilize?A: For the majority of domestic windows, a thickness of 3mm or 4mm is sufficient. For large windows or where optimal soundproofing is needed, 5mm or 6mm might be more proper.

Q: Can I install this on noted buildings?A: Generally, yes. Due to the fact that secondary glazing is an internal addition and does not alter the fabric of the structure's exterior, it is typically allowed. However, it is always suggested to talk to your regional preparation office initially.

Q: How much cash can I minimize energy costs?A: While outcomes vary based on the home, property owners can typically expect to see a 10% to 15% reduction in heat loss through windows, which correlates considerably to lower heating expenses.


Acrylic secondary glazing represents a high-performance, available, and aesthetically pleasing solution for modern home insulation needs. By offering the clarity of glass with the toughness and thermal properties of modern polymers, it enables homeowners to upgrade their living environment without the expense or invasion of complete window replacements. Whether the objective is to reduce energy expenses, obstruct out street noise, or protect a heritage home, acrylic alternatives supply a versatile course toward a more comfy and efficient home.
