How can you insulate a polycarbonate conservatory roof?

In this article, we will explore how you can insulate a polycarbonate conservatory roof effectively, ensuring your conservatory remains comfortable, irrespective of the season.

A conservatory can be a serene retreat, basking in natural light and offering an unobstructed view of your garden. However, with the typical British weather, conserving this serene ambience year-round can be a challenge, especially if your conservatory has a traditional polycarbonate roof. In this article, we will explore how you can insulate a polycarbonate conservatory roof effectively, ensuring your conservatory remains comfortable, irrespective of the season.

What is a polycarbonate conservatory roof?

A polycarbonate conservatory roof is a lightweight, cost-effective roofing material seen on most conservatories around the UK. These roofs are made from robust polycarbonate material, known for its durability and versatility. However, one of the main drawbacks of a polycarbonate roof is its insulation properties - or lack thereof. They often allow too much heat to escape during the winter and can turn your conservatory into a greenhouse during the summer. This is where insulation becomes paramount.

What are the main properties of a polycarbonate conservatory roof?

Polycarbonate conservatory roofs have a number of key properties for homeowners, including:

  • Weight: Polycarbonate is much lighter than glass or solid roofing materials, making it easier to install and less demanding on the conservatory structure.
  • Durability: Despite being lightweight, polycarbonate is highly resistant to impact and less likely to crack or break compared to glass.
  • Insulation: Polycarbonate roofs generally offer lower insulation properties compared to solid roofs or high-quality, double-glazed glass roofs. This means they can be less efficient at keeping heat in during winter and out during summer.
  • Cost: Typically, polycarbonate is more cost-effective than glass, making it an appealing option for those on a tighter budget.
  • Light transmission: Polycarbonate roofs allow high levels of natural light to enter the conservatory, which can be both a benefit and a drawback depending on heat and glare control.

From this list you can see that polycarbonate conservatory roofs have a number of benefits, but their drawbacks are notable - especially when it comes to their lack of beneficial thermal properties. For the best of both worlds, many homeowners turn to conservatory roof insulation.

DIY polycarbonate roof insulation you can do yourself

If you're a DIY enthusiast, there are a few methods you can employ to improve the insulation of your polycarbonate conservatory roof. These include:

  • Using insulating films: These films can be applied to the interior of the polycarbonate panels to reduce heat loss.
  • Sealing gaps: Ensure that all gaps around the roof panels are sealed to prevent draughts, as well as around doors and windows.
  • Adding blinds or curtains: Heavy-duty thermal blinds or curtains can offer an additional layer of insulation.

While these DIY methods can offer some respite, they’re often not enough to tackle the extremes of the British weather efficiently.
