When a flat‑roof room needs more light, **SunTube35 flat EPDM** increases tube diameter to boost illumination while keeping installation simple. The insulated upstand arrives pre‑clad in EPDM for rapid bonding. A crystal glass dome captures daylight cleanly and the mirror‑grade tube transports it efficiently to the diffuser for a comfortable, even wash. Route past services with elbows and add 60 cm extensions up to six metres as required. For low‑energy envelopes, the EcoPower element enhances thermal performance with glazed insulation. Robust, quiet and built for UK weather, **SunTube35 flat EPDM** brings convincing daylight to medium rooms without a large roof opening.
