Awnings Online Cascade - Electric Full Cassette Awning

Specification & Technical Details

The Cascade is engineered for simplicity, durability, and a perfect fit. Below you will find the detailed specifications regarding installation, fabric choices, and motorisation.

Installation & Mounting Options

The Cascade utilises a robust End-Fix design, meaning the entire awning is supported by brackets located at the two outer extremities of the cassette. This design simplifies the installation process significantly, as measurements are straightforward and the load is spread to the outer edges.

• Standard Face Fixing: Supplied as standard with heavy-duty end brackets for face-fixing directly to a flat vertical wall (e.g., brickwork or masonry). This is the most common installation method for two-storey properties and offers a clean, streamlined appearance with minimal protrusion.
• Specialist & Complex Fitting: We understand that not every home has a standard flat wall above the patio doors. Because the Cascade is an end-fix system, we can supply a wide range of specialist brackets to overcome awkward fitting situations, including:
  • Single-Storey Extensions: Spreader plates and gutter brackets to safely mount the awning where wall height is limited.
  • Soffit & Eaves Mounting: Brackets designed to hang the awning from an overhang or soffit board.
  • Pipework & Obstructions: Spacers or standoff brackets to clear downpipes, vents, or other obstacles.
  • Ceiling & Canopy Fixing: Adapted brackets for conservatory bars or pergola beams.

(Please contact our technical team if you require non-standard brackets. We can advise on the best solution for your specific installation challenge).

Cascade Awning Weights (Approx. kg)

The table below shows the approximate weight of the Cascade awning based on width and projection.

The Cascade has been designed with ease of installation in mind. Its end-fix bracket system and compact full cassette design make it one of the most straightforward retractable awnings to fit, particularly suitable for confident DIY installers or professional fitters. This guide provides an overview of the installation process and key considerations.

Is This Awning Suitable for DIY Installation?

The Cascade's 2-bracket end-fix design makes it significantly simpler to install than centre-bracket or multi-point fixing systems. If you are comfortable working at height, using power tools, and have experience with home improvement projects, this awning is within the capabilities of a competent DIY installer.

Key advantages for self-installation:

• Only two fixing points at the outer extremities of the cassette
• Lightweight full cassette construction is easier to handle than open awnings with exposed mechanisms
• Pre-assembled unit arrives ready to hang – minimal on-site assembly required
• Clear measurement points eliminate guesswork
• Standard fixings included for typical masonry walls

When to use a professional installer:

• Working at significant height (above first floor level)
• Fixing to non-standard materials (timber cladding, steel frame, cavity walls)
• Limited experience with structural fixings or power tools
• Properties with listed building status or conservation area restrictions

Tools & Equipment Required

Before starting your installation, ensure you have the following tools and equipment to hand:

Essential Tools:

• Electric drill with selection of masonry and metal drill bits
• Flat-head screwdriver
• Pozidrive (cross-head) screwdriver
• Spanner set (adjustable or fixed)
• 6mm Allen key (hex key)
• Spirit level (minimum 1200mm long recommended for accurate levelling)
• Pencil or marker for marking drill positions
• Tape measure

Additional Equipment:

• Sturdy ladder or scaffolding tower (for safe access to installation height)
• Voltmeter or test lamp (for checking mains supply if wiring motor)
• Assistant (recommended – awnings are easier to position and hang with two people)

Safety Equipment:

• Safety glasses (for drilling)
• Dust mask (for masonry drilling)
• Work gloves

Pre-Installation Checklist

Before beginning installation, carefully assess your property and ensure all conditions are suitable:

1. Structural Suitability

• Wall Condition: Check the wall is structurally sound, free from cracks, and capable of supporting the awning load. Older or deteriorating masonry may require reinforcement.
• Wall Material: Standard fixings are suitable for solid brick, concrete block, or stone masonry. Cavity walls, timber frame, or lightweight construction may require specialist fixings or additional spreader plates (available on request).
• Professional Assessment: If in doubt about structural suitability, consult a structural engineer or qualified builder before proceeding.

2. Measuring & Positioning

• Clear Mounting Area: Ensure there is sufficient clear, flat wall space for the full width of the awning brackets, with no obstructions such as drainpipes, light fittings, or utility boxes.
• Height Requirements: The awning should be mounted at a minimum height of 2.3m from ground level to allow adequate head clearance when fully extended. Consider door heights and window positions.
• Projection Path: Ensure the awning's projection area is clear of obstacles when extended (trees, walls, fences, etc.).

3. Electrical Supply (Electric Models)

• The Somfy IO motor requires a standard 230V mains electrical supply.
• A qualified electrician should install a fused spur or plug socket within reach of the motor cable (typically positioned near the awning bracket).
• Ensure the supply is protected by an RCD (residual current device) for safety.

Installation Overview – Wall Mounted (Face Fix)

The standard installation method for the Cascade is a face-fix directly onto a vertical wall surface. This is the most common method for domestic patio installations above doors or windows.

Step 1: Position the First Bracket

• Measure and mark the position for the first end bracket on the wall, considering space above and below the awning cassette.
• Use a spirit level to ensure the bracket position is perfectly horizontal.
• Mark and drill fixing holes through the bracket plate, using appropriate drill bit size for your chosen fixings.
• Secure the first bracket firmly to the wall using suitable fixings for your wall type (typically M10 or M12 bolts for masonry).

Step 2: Mark the Second Bracket Position

• Measure carefully from the back edge of the first installed bracket using the exact centre-to-centre dimension provided with your specific awning.
• Mark the position for the second bracket, ensuring it is perfectly level with the first bracket. A long spirit level or laser level is highly recommended for accuracy.
• Drill and secure the second bracket in the same manner as the first.

Step 3: Hang the Awning

• With an assistant, carefully lift the awning cassette and hook it onto the wall brackets.
• The cassette should slot easily into the bracket mounting plates.
• Tighten the securing bolts at the bottom of each mounting plate to lock the awning in position.

Step 4: Adjust the Inclination (Pitch)

Once the awning is securely mounted, you can adjust the angle of the front rail to achieve the desired slope for water runoff:

• Fully extend the awning using the motor control.
• Loosen the allen bolts on the adjustment mechanism at each end bracket (typically 6mm allen key required).
• Turn the adjustment bolts clockwise or anti-clockwise to raise or lower the front bar, ensuring equal height adjustment on both sides.
• Once the desired pitch is achieved (typically 10-15° from horizontal for optimal water drainage), retighten the allen bolts securely.
• Check the front rail is level across its width and aligned with the cassette end caps.

Step 5: Install End Caps

• Fit the teardrop-shaped end caps onto the exposed ends of the cassette housing.
• These simply clip or slide into position to provide a neat, finished appearance and weather protection.

Step 6: Electrical Connection & Testing

• Connect the motor power supply following the manufacturer's wiring diagram (qualified electrician recommended).
• Test the awning operation using the supplied remote control or wall switch.
• Programme any additional Somfy IO controls or sensors as required.

Alternative Mounting Options

While face-fix wall mounting is standard, the Cascade's end-fix bracket system is compatible with a range of specialist brackets for more challenging installations:

Ceiling Mounting
If wall mounting is not possible (e.g., single-storey extension with no wall above), ceiling-mounted brackets are available. These allow the cassette to be suspended from a soffit, overhang, or ceiling:

• Use M10 hex bolts (35mm minimum length) to secure the ceiling mounting plates.
• Ensure fixings penetrate into solid timber joists or use suitable heavy-duty anchors for ceiling material.
• Follow the same levelling and spacing procedures as wall mounting.

Soffit & Gutter Brackets
For installations where the awning needs to be mounted under an eaves overhang or fascia board:

• Brackets clamp to the fascia/soffit and extend downward to support the cassette.
• Ideal for properties with limited wall height or where the wall surface is unsuitable.

Stand-Off Brackets (Spacer Brackets)
Used to create clearance between the wall and the awning cassette, useful for:

• Clearing obstructions such as downpipes, external lights, or window cills.
• Mounting on uneven wall surfaces or rendered walls requiring additional standoff.

Please contact our technical team if you require non-standard brackets. We can advise on the most suitable solution and provide custom brackets to suit your installation requirements.

After Installation – Care & Maintenance

Once installed, your Cascade awning requires minimal maintenance to ensure long-lasting performance:

Regular Checks:

• Periodically inspect bracket fixings and tighten if necessary
• Check fabric tension and adjust pitch if sagging occurs
• Clean fabric seasonally with soft brush and mild soapy water
• Retract awning during strong winds (above Beaufort 5) to prevent damage

Winter Storage:

• If possible, retract and leave closed during winter months to prolong fabric life
• The full cassette design provides excellent protection when closed

Motor Maintenance:

• Somfy motors are maintenance-free sealed units
• Battery replacement in remote controls as needed
• Keep motor control switches clean and dry

Measuring Guide - How to Measure for Your Cascade Awning

Getting the correct measurements for your new awning is essential to ensure maximum shading coverage, proper installation, and the best return on your investment. This guide will help you measure your property accurately and identify any potential installation challenges before you order.

Why Accurate Measuring Matters

The Cascade is a made-to-measure awning, manufactured to your exact specifications in the UK. Once ordered, your awning is custom-built and cannot be exchanged for a different size. Taking time to measure carefully will ensure:

• Maximum shade coverage for your patio or terrace area
• Optimal positioning to protect doors, windows, and outdoor furniture
• Correct bracket placement for secure, safe installation
• Value for money by covering the largest practical area

The Three Key Measurements

To specify your Cascade awning, you need three primary measurements:

1. Width (Awning Cassette Width)
   The horizontal dimension of the awning measured along the wall.
2. Projection (Extension Depth)
   The distance the awning extends outward from the wall when fully open.
3. Mounting Height
   The vertical height from ground level to the base of the awning cassette.

Step 1: Measuring the Width

The width determines how much horizontal wall space your awning will cover. For maximum shading, you want the widest awning your wall can accommodate.

How to Measure:

1. Identify your patio doors or windows that you want the awning to shade.
2. Measure the width of the door/window opening including the frames.
3. Add 300-500mm (30-50cm) to each side for optimal shade coverage. This overhang ensures:
   • Sun protection even when the sun is at an angle
   • Shading extends beyond the door frame to reduce glare inside
   • Rain protection for a wider area
4. Check available wall space:
   • Measure the total clear wall space from obstacle to obstacle (corners, downpipes, windows, lights, etc.)
   • The awning cassette must fit within this space with small clearances at each end

Example Calculation:

• Patio doors = 2400mm wide
• Add 400mm each side (2 × 400mm = 800mm)
• Recommended awning width = 3200mm
• Check you have at least 3300mm of clear wall space to accommodate this

Common Awning Widths for UK Properties:

Maximum width for Cascade: 6000mm (with 2.5m projection) or 5500mm (with 3.0m projection)

Important Width Considerations:

• Cassette vs Fabric Width: The awning cassette is the "ordering width" measurement. The fabric canopy will always be approximately 170-220mm narrower than the cassette width due to the mechanism design.
• Measure Across Gutters: If there are gutters or downpipes in the mounting area, measure straight across them as if they weren't there. The awning can be installed in front of gutters, or we can supply extension brackets to clear obstructions.

Step 2: Measuring the Projection

The projection determines how far the awning extends from the wall and therefore how much ground area it will shade. Maximising projection provides the greatest UV protection and usable outdoor space.

How to Measure:

1. Stand with your back to the wall at the intended mounting point.
2. Walk forward to where you want the front edge of the awning to reach when extended.
3. Measure straight back to the wall in a perpendicular line. This is your required projection.

Consider your patio furniture:

• Small café table (2 people) = 2.0m projection minimum
• Standard dining table (4-6 people) = 2.5m projection minimum
• Large dining table (6-8 people) = 3.0m projection recommended

Standard Projections Available:
The Cascade is available in four projection sizes: 1.5m, 2.0m, 2.5m, 3.0m

Understanding Shaded Area:
Because awnings are installed at an angle (typically 10-15°) for water drainage, the actual shaded ground area is less than the projection measurement:

• 2.5m projection = approximately 1.5-2.0m of shaded ground coverage
• 3.0m projection = approximately 2.0-2.5m of shaded ground coverage
• 3.5m projection (not available on Cascade) = approximately 2.5-3.0m of shaded ground coverage

Tip: Test the shade area at different times of day. Stand on your patio at noon and mid-afternoon to visualise where the awning shadow would fall.

Width to Projection Ratio:
The standard recommendation is for projection to be 0.5m less than the width. For example:

• 3.0m wide awning → 2.5m projection
• 4.0m wide awning → 3.5m projection (not available on Cascade, max 3.0m)
• 5.0m wide awning → suitable with 2.5m or 3.0m projection

This ratio ensures the awning maintains structural integrity in wind and has balanced proportions.

Step 3: Measuring the Mounting Height

The mounting height determines where the awning cassette will be fixed to the wall. This affects head clearance underneath and the overall pitch angle.

Standard Mounting Heights:

• Minimum recommended height: 2.5m from ground to the base of the cassette
• Typical installation height: 2.7-3.0m for standard domestic properties
• Minimum head clearance required: 2.0m at the front edge when extended

How to Determine Mounting Height:

1. Measure from ground level to the underside of any eaves, soffits, or fascia boards.
2. Measure down from the eaves to the top of your door or window frame.
3. Identify a suitable row of bricks for bracket fixing:
   • The mounting position should be at least 450mm above the door/window lintel
   • Choose a course of bricks or blockwork (not mortar joints) for solid fixing
   • Mark this position with chalk
4. Calculate the front bar height when extended:

Formula:
Front height = Mounting height - (Projection × sin(pitch angle))

Example with 15° pitch:

• Mounting height = 2.8m
• Projection = 3.0m
• Front height = 2.8m - (3.0m × 0.259) = 2.8m - 0.78m = 2.02m

This ensures adequate head clearance.

Height Constraints to Check:

• Window clearance above: Ensure awning cassette doesn't obstruct opening windows
• Shutter clearance: If you have external shutters, ensure they can fully open without hitting the cassette
• Access for maintenance: Can you comfortably reach the awning for cleaning?
• Building aesthetics: The awning should be proportionally positioned on the facade

Assessing Wall Suitability & Structural Challenges

Many UK properties present installation challenges beyond simple measuring. Before ordering, carefully assess your wall structure and mounting surface.

Ideal Wall Conditions:

• ✓ Solid brick or blockwork construction (traditional cavity wall or solid wall)
• ✓ Wall thickness of at least 225mm (9 inches)
• ✓ Good condition masonry with sound mortar joints
• ✓ Flat, vertical surface with no render cracks or bulging
• ✓ Clear mounting area at least 2.5m wide minimum

Common Installation Challenges:

1. Modern Cavity Wall Construction

• Issue: Many modern homes have cavity walls with thin outer skins (102mm) and insulation-filled cavities.
• Solution Options:
  • Heavy-duty through-wall fixings that bridge the cavity and anchor into the inner blockwork
  • Spreader plates to distribute load across multiple brick courses
  • Structural assessment may be required for very wide awnings

2. Timber Frame or Steel Frame Buildings

• Issue: Lightweight construction with cladding over timber or steel framework provides inadequate fixing substrate.
• Solution Options:
  • Custom brackets designed to fix into structural frame members (requires knowledge of frame positions)
  • External mounting posts or columns to support the awning independently
  • Professional structural engineer consultation recommended

3. Rendered or Insulated External Wall Systems (EWI)

• Issue: External wall insulation creates a gap between the render/cladding and the structural wall.
• Solution Options:
  • Extra-long fixings that penetrate through insulation to solid substrate
  • Thermal bridge considerations (consult installer)
  • May affect building warranty if EWI is recently installed

4. Single-Storey Extensions or Conservatories

• Issue: Limited wall height above doors/windows, or no wall at all (glass roof).
• Solution Options:
  • Soffit or ceiling mounting brackets – awning hangs from the underside of the roof overhang
  • Fascia brackets – fix to the fascia board (requires solid timber backing)
  • Gutter mounting brackets – specialised brackets that clamp to substantial guttering
  • Structural adequacy of timber roof structure must be verified

5. Obstructions in Mounting Area

• Issue: Downpipes, external lights, security alarms, utility meters, or cables in the ideal mounting position.
• Solution Options:
  • Stand-off brackets – create 100-300mm clearance to bypass obstructions
  • Relocate services – move downpipes, lights, or cables (may require tradesperson)
  • Adjust awning position – shift left or right to avoid obstruction (may reduce coverage)

6. Listed Buildings or Conservation Areas

• Issue: Planning restrictions or listed building consent requirements.
• Solution:
  • Check with local planning authority before ordering
  • Awnings may require Listed Building Consent
  • Frame colour restrictions may apply (e.g., must match existing joinery)

7. Insufficient Wall Height

• Issue: Bungalows, dormer windows, or properties with low eaves may not have adequate space above doors.
• Solution Options:
  • Reduce projection to minimise pitch angle drop
  • Increase mounting height as close to eaves as possible
  • Consider a smaller awning or alternative shading solution
