EZ Glaze Polycarbonate Roofing Sheets: The Complete Buying & Fitting Guide

EZ Glaze Polycarbonate Roofing Sheets: The Complete Buying & Fitting Guide

EZ Glaze is a glass-like profiled polycarbonate roofing sheet that gives you the clear, contemporary look of a glass roof without the weight, cost or fragility. If you're planning a conservatory roof, lean-to, carport, pergola or patio cover, this guide explains exactly what EZ Glaze is, how it compares to glass, the sizes and colours available, what it costs, what you need to fit it, and how the installation works.

What is EZ Glaze?

EZ Glaze is a 3mm profiled (lightly corrugated) polycarbonate sheet made by Palram, the maker of the Suntuf range. It's engineered to look like glass while being virtually unbreakable. The clever part is the shaped edge: sheets simply overlap and screw straight onto timber rafters, so no glazing bars are needed — which is what makes it so quick and affordable to install compared with a glass or multiwall conservatory roof.

EZ Glaze vs glass: which should you choose?

For a roof you'll walk under, light, weight and safety usually matter more than anything else. Compared with a traditional 3mm glass roof, EZ Glaze offers near-identical clarity (both around 90% light transmission), but it's roughly 200 times stronger, about 50% lighter, and far simpler to install — it screws to rafters with no specialist glazing, making it genuinely DIY-friendly. Glass, by contrast, is heavy, brittle and almost always needs a professional. In short: EZ Glaze gives you the look of glass with a fraction of the weight and risk.

EZ Glaze colours and tints

Every EZ Glaze sheet blocks virtually all UV. The tint you pick controls how much light and heat passes through:

• Clear (~90% light transmission) — maximum brightness; a true glass-like finish.
• Beehive, prismatic (~87%) — bright but glare-free; diffuses light and softens shadows.
• Bluish Breeze (~70%) — an attractive blue tint with good brightness and mild heat reduction.
• Solar Ice / opal (~20%) — privacy and shade; soft, diffused light with the most heat control.

EZ Glaze sizes and coverage

EZ Glaze sheets are 688mm wide and cover 600mm once overlapped. They come in lengths of 2.5m, 3m, 3.5m, 4m and 6m (7m on request), so you can match the run of your roof with minimal cutting. To work out how many sheets you need, divide your roof width by 0.6m (the cover width) and round up, then choose the length closest to your rafter run.

How much does EZ Glaze cost?

EZ Glaze is priced per sheet by length and tint. As a rough guide, clear sheets start from around £60 (ex VAT) for a 2.5m sheet and rise with length; the lower-cost Beehive option starts a little below that. Accessories — fixing screws, foam tape and wall flashing — are sold separately. For live, up-to-date pricing on every size and colour, see the product pages.

What do you need to fit an EZ Glaze roof?

A complete EZ Glaze roof typically needs:

1. EZ Glaze sheets in your chosen tint and length.
2. Fixing screws and EPDM washers — one every 500mm along each rafter.
3. Foam / friction-reduction tape — along the top of every rafter.
4. Wall flashing — where the roof meets a house wall.
5. Guttering and brackets — to drain the low edge.
6. Neutral-cure silicone — a polycarbonate-safe sealant.

How to install EZ Glaze (step by step)

1. Build timber rafters (up to 50–60mm) at 600mm centres, set at a minimum 5° pitch. No purlins needed.
2. Run foam tape along the centre of each rafter to cut friction and noise.
3. Lay the first sheet with a 50–150mm overhang at the eaves.
4. Pre-drill 10mm clearance holes through the outer corrugation, max 500mm apart (oversized holes allow for thermal expansion).
5. Fix down with EZ Glaze screws and washers.
6. Overlap the next sheet's edge over the last and fix through both.
7. Finish at the wall with flashing and neutral-cure silicone.

What can you use EZ Glaze for?

EZ Glaze suits any pitched, rafter-supported roof where you want light through: conservatory roofs, lean-to roofs, carports, pergolas, patio and decking covers, porches and canopies. Its light weight and simple fixing make it a popular choice for both DIY projects and trade installers.

EZ Glaze FAQs

Is EZ Glaze as clear as glass? The clear tint transmits up to ~90% light — virtually identical to glass — but is around 200 times stronger and half the weight.

Do I need glazing bars for EZ Glaze? No. The profiled edge overlaps and self-supports across 600mm rafter centres, so no glazing bars are required.

What sizes does EZ Glaze come in? Lengths of 2.5m, 3m, 3.5m, 4m and 6m (7m on request). Each sheet is 688mm wide and covers 600mm once overlapped.

Can I install EZ Glaze myself? Yes. It cuts with a fine-tooth saw and fixes with screws to timber rafters — no specialist tools or glazing systems needed.

Is EZ Glaze covered by a warranty? Yes — a 10-year manufacturer warranty on UV performance and light transmission.
