Whether you are building a lean-to side shelter or connecting a shed roof to a brick wall, the junction between a sloping roof and a vertical wall is the most common point for water leaks. ONDULINE® Apron Flashing creates a smooth, watertight seal that deflects rain away from wall abutments and upstands.

Key Benefits

• Superior Waterproofing: Prevents heavy rain and running water from seeping into wall joints and causing internal damp.
• Matched Corrugation Profile: Available in profiles tailored specifically for Onduline sheets to guarantee a snug, leak-proof seal.
• DIY Friendly: Lightweight and flexible - easy to trim to size and fasten with standard fixings.
• Durable Construction: Made from weather-resistant Polypropylene (PPE) built to withstand intense sun, frost, and wind.

Maintain healthy airflow across the roof void while keeping out debris, birds, and insects.

• Dimensions: 1000 mm (L) x 68 mm (H) x 20 mm (W)

• Weight: 0.1 kg

• Material: Tough, UV-resistant Polypropylene (PPE)

Condensation build-up inside a shed or garden room can lead to damp walls, mouldy tools, and rotting timber. The ONDULINE® Eaves Ventilator Strip provides continuous airflow through the eaves while keeping out birds, rodents, and large debris.

Key Benefits:

• Combats Internal Condensation: Keeps air circulating freely across the roof space to protect timber health.
• Integrated Pest Shield: Fine ventilator mesh deters birds, rodents, and leaf debris.
• Simple to Fix: Easily nailed into place along the eaves before sheets are laid.
• Durable: Made from tough Polypropylene (PPE) resistant to high temperatures and UV rays.

• Dimensions: 1500 mm (L) × 55 mm (H) x 190 mm (W)
• Weight: 0.8 kg (+/-0.2 kg)
• Material: Robust UPVC / UV-resistant Polypropylene (PPE)

Water running off the lower edge of a roof can seep backward underneath the sheets, damaging your fascia boards and timber decking. ONDULINE® Eaves Trays (1500 mm × 190 mm) create a smooth, rigid drip edge that directs rainwater straight into your gutter.

Key Benefits:

• Prevents Fascia & Membrane Rot: Stops water from dripping onto underlying timber or underlays.
• Customisable Drip Edge: Pre-formed fold lines allow you to adjust the drip edge.
• Reduces Sheet Overhang: Allows you to install sheets with less overhang, preventing wind uplift and sheet sag.
• Heavy-Duty Construction: UV-resistant UPVC/PPE built to handle heavy rain and winter ice.

• Material: Cross-linked polyethylene

• Available Profiles:

  1. ONDULINE CLASSIC / EASYLINE (1056 mm x 40 mm)

  2. ONDULINE EASYFIX / DURO SX 35 (1008 mm x 41 mm)

ONDULINE® FOAM FILLERS are available in two different profiles to match the profile range of ONDULINE® bitumen roof sheets and tiles and ONDUCLAIR® plastics.
ONDULINE® FOAM FILLERS should be used to seal the corrugations at eaves and ridges of the bitumen sheets and plastics ranges. 

Key Benefits:

• Complete Gap Sealing: Fills every corrugation gap tightly at the ridge and eaves to stop wind-driven rain and snowmelt.
• Draught & Thermal Shield: Keeps cold winds from blowing through your building, making garden rooms and workshops warmer and easier to heat.
• Pest Barrier: Prevents birds, wasps, mice, and insects from nesting inside your roof structure.
• Easy Push-Fit Installation: Simply press the foam strips into place along the eaves or beneath the ridge caps prior to fixing.

• Available Grammages: 100 gsm | 120 gsm | 140 gsm | 160 gsm 

Suitable for both cold and warm roof applications, these membranes are crucial for comprehensive moisture management. Optimal Condensation Control & Waterproofing: It is best practice to install a breathable membrane, such as ONDUTISS AIR, beneath Onduline roofing sheets, tiles, and BARDOLINE roof shingles. This ensures robust protection against condensation build-up, contributing to maximum waterproofing performance and long-term roof health.

Key Benefits

• Allows moisture vapor to escape from the roof structure, preventing condensation build-up, mould, and rot
• Acts as a reliable secondary barrier against water penetration
