Multi-layer reflective foil installed across rafters reflects up to 95% of radiant heat back into the home, brightens the loft 4× over, and prevents the dust and felt fibre fall-out from old underlay roofs.

Who it's for Owners of older properties with degrading bitumen felt underlay (the black gritty stuff that sheds onto stored items). Anyone wanting a cleaner, brighter loft for storage or future conversion. Homes with rooms-in-roof needing additional rafter-line insulation. When you need it Whenever felt underlay starts shedding, after any roof works that exposed the rafters, or as part of a comprehensive insulation upgrade for hard-to-treat properties. Why it matters Conventional fibre insulation only blocks conducted and convected heat. Reflective foil tackles radiant heat, the dominant heat-loss mode through pitched roofs in summer and heat-gain in winter sun. The Real Cost of Ignoring This ## Why Old Lofts Get Dusty, Dim and Damp If your loft looks black, smells musty and showers grit every time you climb in, your roof underlay is breaking down. Foil lining solves it in a day. ### What it costs to ignore - Bitumen felt fibre fall-out contaminating stored items, suitcases and Christmas decorations. - Radiant heat-gain in summer baking the loft to 50°C+, raising bedroom temperatures below. - Cold-bridging through rafter timber accounting for 15–20% of total roof heat loss. - Dim, dirty interiors making loft access genuinely unpleasant and unsafe. - Wind-driven dust ingress through felt cracks during westerly gales. ### Common mistakes we fix - Stapling foil with the wrong side facing, reflective coating must face the air gap. - Sealing foil tight against rafters with no air gap, eliminating the radiant barrier effect. - Using single-layer foil where multi-layer is required for the claimed R-value. - Forgetting to maintain eaves and ridge ventilation when lining the rafter line. Our Process ## The 5-step foil loft lining system 1. 01 ### Free Survey & Quote We assess rafter spacing, existing felt condition, ventilation paths and lighting. Fixed quote on the day. 2. 02 ### Loft Prep & Clean We vacuum the loft, remove loose felt debris and protect existing insulation and pipework. 3. 03 ### Foil Install Multi-layer reflective foil stapled across rafters with reflective face inward, joints sealed with foil tape, eaves and ridge ventilation paths preserved. 4. 04 ### Lighting & Final Detail Optional LED strip or pendant lighting installed against the new bright reflective surface, most clients add this. 5. 05 ### Sign-Off Photo report, guarantee and care advice. Why It's Worth It ## The measurable benefits ### Clean, Bright Loft Reflective surface bounces light 4×, torch-free access for the first time in years. ### Stops Felt Fall-Out Captures bitumen grit and fibre that would otherwise contaminate stored belongings. ### Adds Up to R-3.5 Multi-layer foil with two air gaps adds genuine thermal performance on top of any existing insulation. ### Cooler Bedrooms in Summer Reflects radiant heat back through the roof, reducing first-floor temperatures by 3–5°C in heatwaves. ### Future-Proofs Loft Conversion If you ever convert the loft, the foil layer becomes part of the rafter-line insulation build-up. ### Day-Rate Install Standard pitched roof lined in a single working day with zero disruption.

Done well, it's transformative; done badly, it's a £400 waste of staples. Material spec, air gap and ventilation continuity all matter. ### Multi-Layer vs Single-Layer Foil Single-layer foil reflects radiant heat but adds negligible thermal resistance. Multi-layer products like Actis Hybris (8 layers, 35mm) or SuperFOIL SF40 add genuine R-2.5 to R-3.5 of thermal performance. ### Air Gap Theory Reflective foil only works with an air gap of at least 25mm on the reflective face. We always install with stand-off battens to maintain the gap and double its effectiveness. ### Vapour Permeability Older bitumen felt is impermeable, trapping moisture. Modern breathable foil membranes (Tyvek Reflex, Klober Permo Air) allow water vapour out while still reflecting radiant heat. ### Ventilation Continuity Lining the rafter line is only safe if eaves and ridge ventilation paths are preserved. We never seal the loft, cold-roof airflow continues uninterrupted. ### Combined With Mineral Wool Foil works best as a complement to, not replacement for, traditional insulation. Belt-and-braces installs combine 270mm at joist level with rafter-line foil for total thermal envelope.
