Best Glazing Materials For Cold Frames

Selecting an appropriate glazing material depends on project priorities. Acrylic tends to offer clear optical qualities and ease of fabrication; polycarbonate provides strength, safety and UV resistance benefits.

Polycarbonate provides unparalleled impact resistance and is virtually unbreakable, while still maintaining structural integrity over a wide temperature range compared to PVC or glass. Furthermore, it resists UV damage much better.

Optical Clarity

Acrylic glass (commonly known by its initials plexiglass) is an economical, long-term and chemical resistant thermoplastic that provides a durable alternative to traditional glazing materials. Ideal for applications that demand heat resistance and chemical stability.

Polycarbonate, on the other hand, is virtually unbreakable and highly impact resistant, making it suitable for areas prone to impact damage like security glazing or machine guards. Furthermore, its lenses, screens and shields offer resistance from oils, fuels and caustic cleaning agents that could otherwise compromise acrylic glass surfaces.

As neither acrylic nor polycarbonate provide superior optical clarity, they each possess distinct strengths that make them suitable for retrofitting double-glazing systems that improve thermal performance and decrease noise levels.

Impact Resistance

Polycarbonate is renowned for its cost-effectiveness, making it a durable material ideal for safety glazing in stairwells, walkways and roof terraces. Virtually unbreakable under heavy impacts (unlike glass that cracks and shatter) it outshines PVC over time in harsh conditions – making it the go-to material. This material also stands up better against UV light. This makes polycarbonate ideal for safety glazing applications on walkways or roof terraces.

Insulated skylights offer limited insulation but reduce noise pollution and filter UV rays – ideal for urban dwellers. When combined with laminated or tempered glazing, they meet BS 5516 standards for walk-on or anti-theft skylights.

Acrylic is relatively straightforward to cut, route and slot into curved frames; however, its impact resistance is lower than glass and it hazes and yellows over time, particularly outdoors. Multiwall polycarbonate sheets offer increased durability and insulation – choose clear bronze and opal tinted versions for better insulation if your area poses moderate bushfire risks. Alternatively, fully toughened laminated glass skylights offer premium clarity, excellent thermal performance and help maintain comfortable indoor temperatures year-round.

Lightweight

Acrylic and polycarbonate sheets offer substantial energy savings compared to glass roofing due to their superior insulation properties, as well as reduced noise levels and enhanced safety through enhanced strength and durability.

Acrylic offers exceptional optical clarity and is an excellent material choice for displays, signage, lenses and transparent structures that require maximum transparency. Acrylic’s resistance to fading over time remains undamaged by mineral acids, alkalis, aliphatic hydrocarbons or alcohols – making it the ideal material choice.

Laser cut acrylic offers a lightweight alternative to glass, offering smooth polished edges with laser precision cutting capabilities. Furthermore, it’s easily cleanable and resistant to scratches – ideal features in an economical alternative!

Polycarbonate is 17 times stronger than glass and virtually unbreakable, making it an excellent impact resistant material for use in applications requiring safe solutions such as riot shields, security glazing, sports arena barriers and machine guards. Available as clear tinted multiwall sheeting as well as domed skylights; UV stabilised coatings extend its lifespan further, as do different colors such as bronze and opal options for enhanced opacity and lifespan enhancements; all are UV stable options too!

Energy Efficiency

Glass provides excellent thermal performance, preventing both heat loss during winter and overheating during summer, increasing comfort year-round and lowering energy bills. Furthermore, this material stands up well in Albury’s harsh weather as it resists hailstorms and other debris effectively.

Acrylic glass (commonly referred to as Plexiglass) is an economical plastic with excellent optical clarity and scratch resistance that lacks the strength of polycarbonate. Ideal for budget skylight kits and smaller units, laminated or tempered glasses may also be combined to meet BS 5516 safety glazing standards.

Solid polycarbonate sheets are virtually unbreakable and come in clear, bronze, opal and black tints for added insulation and cost efficiency. Multiwall sheets also reduce costs by offering various degrees of insulation; making solid polycarbonate an ideal choice for impact resistant applications like riot shields, security windows or sports arena barriers; aquariums dome roofs and retail displays can all use polycarbonate as an additional layer.
