The Silent Gliss SG 4970 is the heavy-duty motorised roller blind in the Silent Gliss electric range — the system specified when window width, fabric weight or the combination of both exceeds what the SG 4960’s 41mm tube can accommodate reliably. Its larger diameter aluminium tube carries heavier fabric weights across wider spans without the tube deflection — the visible sagging in the centre of an undersized tube — that affects smaller-diameter motorised roller blinds across large window openings. This makes the SG 4970 the definitive specification for principal glazing in large living areas, wide commercial facades, floor-to-ceiling hospitality windows and any installation where a standard motorised roller blind tube would produce an unacceptable result across the full width.
The SG 4970 is motorised via a higher-torque tubular motor suited to the increased fabric weight and tube diameter, with smooth progressive start and stop motion and precise positional memory — the blind returns to exactly the same stop position on every operation regardless of the fabric weight it is carrying. It is made to measure in the full range of Silent Gliss roller blind fabrics, including blackout for bedroom and media room installations, solar screen at 3% and 5% openness for south and west-facing commercial glazing, and dim-out for living areas and meeting rooms requiring privacy without full blackout.
Control is via wall switch, remote handset and smart home or BMS integration — we confirm the appropriate control interface for the specific platform at the specification stage, and work directly with AV integrators and BMS engineers to co-ordinate wiring requirements and commissioning from the design stage. As an authorised Silent Gliss dealer, we supply and install the SG 4970 across Poole, Dorset and the South Coast, including on-site survey, fabric selection, motor wiring co-ordination and full installation and commissioning.
For standard residential window widths, the SG 4960 is the more appropriate motorised specification. For the manual equivalent at this tube diameter, the SG 4930 is the corresponding hand-operated system. Contact our team for a free site survey and specification advice.

FAQ
What is the Silent Gliss SG 4970?
The Silent Gliss SG 4970 is a heavy-duty electrically operated roller blind from the Silent Gliss range, designed for wide-span windows, commercial glazing and high-load residential installations where the standard SG 4960’s 41mm tube is insufficient. Its larger diameter aluminium tube carries heavier fabric weights across wider spans without tube deflection, and its higher-torque motor provides smooth, reliable motorised operation across the full fabric width with precise positional memory. The SG 4970 is made to measure in blackout, dim-out and solar screen fabrics and is suitable for luxury residential and contract applications. We supply and install the SG 4970 across Poole, Dorset and the South Coast as an authorised Silent Gliss dealer.
What is the difference between the SG 4970 and the SG 4960?
Both are motorised Silent Gliss electric roller blinds in the same range, but they differ in tube diameter, motor torque, span capability and intended application. The SG 4960 uses a 41mm aluminium tube and is the correct specification for standard residential window widths up to 2,400mm as a single system. The SG 4970 uses a larger diameter tube with a higher-torque motor, giving it greater maximum fabric width and the ability to carry heavier fabrics across wider spans without the tube deflection or motor strain that affects the SG 4960 beyond its design limits. For standard residential and smaller commercial windows, the SG 4960 is the appropriate motorised specification. For wide principal glazing, large commercial facades and any window where fabric width or weight exceeds the SG 4960’s capability, the SG 4970 is the correct choice. We confirm the appropriate system for each window during the pre-installation site survey.
Is the SG 4970 suitable for commercial and contract installations?
Yes. The SG 4970’s heavy-duty tube, higher-torque motor and wide-span capability make it the correct motorised roller blind specification for commercial facades, hospitality rooms, healthcare environments and contract residential developments where both blind width and long-term motorised reliability are governing criteria. Its precise positional memory ensures the blind returns to the same stop position on every operation regardless of the fabric load — an important performance characteristic in commercial environments where consistent, repeatable blind positioning is expected by multiple users. We work with architects, M&E consultants, main contractors and facilities managers on commercial and contract roller blind specifications across Dorset and the South Coast.
Do you install the SG 4970 in Poole and across Dorset?
Yes. We are an authorised Silent Gliss dealer supplying and installing the full Silent Gliss motorised roller blind range — including the SG 4970 — across Poole, Bournemouth, Canford Cliffs, Sandbanks, Christchurch, Salisbury and the wider Dorset, Hampshire and South Coast area. Every installation begins with a free on-site survey to confirm window dimensions, fabric selection, motor specification and smart home or BMS compatibility. Contact our team to discuss your project.
