Pergola glazing and garden screens: design and installation choices

Request roof panels, side screens or sliding glass for a garden structure, with the existing frame and weather exposure assessed first.

Pergola glazing can mean a complete glazed roof or screens around an existing outdoor structure. The supplier needs to understand which elements are already installed.

Clear roofs preserve daylight while solar-control glazing and blinds change the balance of shade and heat. Discuss water run-off, cleaning access and the ability to replace individual panels.

Measurement reference

Enter one opening or proposed roof width and projection / screen height. Identify the measurement reference in the notes and list other bays separately.

Budget and optional extras

Retrofit screens, structural strengthening and sliding enclosures require their own quote.

Published prices on the main page state their reference size, supply or fitting scope, VAT basis and source. Add-ons are individually requested in the configurator and need separate supplier pricing.

Pergola glazing and garden screens for your project

Common enquiry briefs include pergola roof glazing, fixed garden screen, sliding pergola sides, gazebo glazing. Describe the intended use and the supporting construction so the supplier can assess the complete specification. Different applications can need different glass processing, fixings and installation details.

Check the existing frame

A structure designed for light shade fabric may not support glass. Supply its drawings and ask for structural review.

Roof-only and sliding sides differ

Roof gaskets, drainage and side tracks have different interfaces. Request a coordinated system rather than loose panels alone.

What to include in a made-to-measure quote

Compare quotes using the same dimensions, quantities, finish, glass construction and installation scope. If you have a drawing or an existing specification, include its reference and identify which details still need advice.

  • Existing support structure: Photograph the frame and provide member sizes or drawings.
  • Glazing position: Overhead glass and side screens need different assessment.
  • Glass appearance: Ask for a physical sample where colour or privacy matters.
  • Side-panel operation: Specify track level, thresholds and drainage.
  • Tracks, channels and gaskets: Confirm compatibility and movement allowance.
  • Roof drainage / flashing: Agree falls and water discharge before manufacture.
  • Shading / insect screens: Ask for a compatible independent system.
  • Integrated lighting: Specify weather suitability and electrical access.
  • Frame assessment / strengthening: Existing pergolas may not be designed for glass weight or wind loads.
  • What should the quote include?: Ask suppliers to itemise delivery, measurement and fitting separately.

Cut-to-size dimensions, edges and fabrication

Measure the finished glass only when the fitting allowances and support details are known. Otherwise identify the opening or existing panel you measured and request a survey. Give each different size its own basket line, with its quantity and drawing reference.

Holes, cut-outs, shaped edges and interfaces with hardware should be settled before manufacture. The finished glass construction and any coatings must suit the intended environment. A screen preview or concept photograph cannot replace a sample, survey or product-specific installation drawing.

Supplier checks before manufacture

  • No compatibility with an existing pergola is assumed. Assess dead load, wind, snow, foundations and anchorage.
  • An ordinary garden screen is not guarding or pool-safety fencing unless designed and evidenced for that use.
  • The supplier must agree the final sizes, construction and compatible fittings before manufacture.
  • Confirm survey, packaging, delivery, access and installation responsibilities in the written quote.

Requesting comparable glass quotes

Save the choices you know and ask for help with the rest. The quote basket records a specification request rather than placing a manufacturing order. A firm quote needs an agreed final build, dimensions, delivery arrangements and any installation or design work.

When comparing proposals, check that glass-only supply and supply with fitting cover the same scope. Ask who provides measurement, drawings, supports, compatible hardware, lifting access and finishing work. Keep the final approved specification with the order.

Before you choose

The decisions that matter

01

Check the existing frame

A structure designed for light shade fabric may not support glass. Supply its drawings and ask for structural review.

02

Roof-only and sliding sides differ

Roof gaskets, drainage and side tracks have different interfaces. Request a coordinated system rather than loose panels alone.

  • No compatibility with an existing pergola is assumed. Assess dead load, wind, snow, foundations and anchorage.
  • An ordinary garden screen is not guarding or pool-safety fencing unless designed and evidenced for that use.
  • The supplier must agree the final sizes, construction and compatible fittings before manufacture.
  • Confirm survey, packaging, delivery, access and installation responsibilities in the written quote.

Useful questions

Can I get a quote before I know every detail?

Yes. Choose Help me choose where you need advice, or request a site measurement. Suppliers can review the brief; a firm manufacturing price needs an agreed final specification.

Does adding a panel place an order?

No. It saves a specification in your quote basket. Review the basket and provide your delivery details to request supplier quotes. Your configuration does not approve the product for installation.
