Filon® Products We Install

Our Tritec teams are fully accredited to install the full range of Filon® GRP products. From rooflights to over-roofing solutions, each system is designed to enhance durability, safety, and natural light for commercial and industrial buildings.

Filon® Supasafe & DR Reinforced Profiled Rooflights

Supasafe rooflights are triple-reinforced with polyester resins and glass fibre mats, including extra woven glass layers. They are tested for non-fragility to Class B standards and provide impact resistance and load-bearing capabilities comparable to 0.7mm steel sheets, offering both safety and durability.

Filon® FAIRs Factory-Assembled Insulating Rooflights

These high-quality GRP rooflights are pre-assembled to provide a simple in-plane solution for composite panel roofs and walls. Available in double and triple-skin formats, they deliver excellent insulation while scattering natural light evenly, reducing glare and shadows.

Double-Skin GRP Box Rooflights (Filon Filites)

Filon Filites are designed for internal linings, such as suspended ceilings or purlin linings, and are perfect for integrating with older roofing systems. These double-skin GRP box rooflights allow natural light to pass through while maintaining balanced insulation levels.

Filon Monarch-F GRP Barrel Vault Rooflights

Monarch-F barrel vault rooflights are arched roof systems that provide continuous daylighting and durability. Suitable for flat, curved, and standing seam roofs, they are ideal for factories, warehouses, and retail spaces, offering both aesthetic appeal and practical performance.

Filon® Citadel Sheets

Citadel sheets are GRP roofing and wall cladding solutions built to withstand harsh, corrosive environments such as galvanising plants, chemical works, and coastal buildings. Available in a variety of profiles and colours, they offer long-lasting protection where steel may fail.

Horticultural Fotolite GRP Glazing

Designed for maximum daylight without hot spots or glare, these profiled GRP rooflights are available in over 900 profiles to match current or discontinued metal and asbestos cement roofs. Ideal for industrial, agricultural, or commercial projects requiring effective, evenly distributed lighting.

Refurb Over-Roofing

The patented Filon Over-Roofing system provides a quick, cost-effective, and environmentally friendly way to refurbish existing roofs. It offers a durable, waterproof GRP skin over older roofs, helping extend lifespan and improve building performance.

Filon Fixsafe Rooflights & GRP Roof Sheets

The Fixsafe safety fixing system allows safe replacement of GRP roof sheets and rooflights from inside the building, reducing the risk of falls and improving site safety during refurbishment projects.
