NOTE - There is an error in this ones' roof as the imp sheets cannot curve. this is corrected with the pic below it. Single uninsulated sheets could be used then curved over plastic water pipe or wood frame & spray foamed by hand

If you cannot afford insulated metal panels (IMP panels), pallets can be used, then filled with used plastic bottles filled with water, sand, bubble wrap / other used plastic to insulate the wall, then spray the gaps with expanding foam . cover with scrap pallet wood at your leisure.

For those on a very low budget or unable to transport metal roof sheets, household cans and plastic bottles can be cut, folded and fixed to thoutside of the pallets .  How we transformed 498 aluminium cans into a roof  Make Shingles and Siding Out of Aluminum Cans (Beer Can Roof)

1st draft of a UK-specific, practical emergency hardware kit you can assemble in advance to protect windows and doors by securing plywood, OSB, or even detached fence panels to external walls when a severe storm (up to ~120 mph gusts) is imminent.

 

Below is a UK-specific, practical emergency hardware kit you can assemble in advance to protect windows and doors by securing plywood, OSB, or even detached fence panels to external walls when a severe storm (up to ~120 mph gusts) is imminent.

I’ve included:

1. What the kit should contain,

2. How to estimate fixing quantities per window,

3. Optional but highly recommended extras,

4. Guidance on using fence panels as a last-resort material.

1. Core items for the Emergency Window-Protection Hardware Kit

A. Wall plugs (for masonry fixing)

• Type: UK brown (7mm drill) or blue (10mm drill) masonry plugs.

• Strength: Choose high-grip, anti-rotation types.

B. Exterior screws

• Type: Normal screws or ideally A2/A4 stainless steel or exterior-grade coated wood screws (to avoid snapping under load or corroding).

• Length:

  • For 18mm plywood/OSB → 5.0 × 70 mm screws

  • For fence panels (25–45mm thick frames) → 5.0 × 100 mm screws

C. Penny washers

• Large diameter: M5 or M6, 25–30 mm OD
  Washer spreads load, stopping the screw head pulling through under suction loads.

D. Drill bits

• 7mm and 10mm masonry bits (match your wall plugs)

• 3–4mm pilot bit for pre-drilling the wood panel

E. Driver bits

• PZ2 and PZ3 impact-rated bits.

F. Seal/anti-lift tape or foam

Used to:

• Reduce panel rattle

• Reduce wind getting behind the panel
  Suitable materials:

• High-tack exterior duct tape

• EPDM window sealing foam strip (self-adhesive)

G. Marking & measuring tools

• Sharpie or lumber crayon

• Tape measure

• Masking tape (to label panel/window locations)

H. PPE

• Safety glasses

• Dust mask

• Gloves

• Ear protection (drilling)

2. Estimate: Amount of Screws & Wall Plugs Needed (for 120 mph gusts)

Load assumption

Storm-rated boarding in hurricane regions uses 6–8" screw spacing around edges.
For the UK, 120 mph gusts are extreme, so we use hurricane-standard density:

Recommended screw spacing for plywood/OSB panels

• Every 150–200 mm around the perimeter

• Every 300–400 mm on internal lines (if panel is large)

• Minimum 12 screws per typical window board

Typical UK window sizes

Let’s estimate for 3 common types:

Window Size	Typical board size	Screws per panel (120 mph spec)
600 × 900 mm (small)	One sheet	12 screws
900 × 1200 mm (medium)	One sheet	16–20 screws
1200 × 1500 mm (large)	One sheet	24–28 screws

Whole-house estimate

Assuming an average UK 3-bed semi with ~10 windows:

• 3 small windows → 3 × 12 = 36 screws

• 5 medium windows → 5 × 18 ≈ 90 screws

• 2 large windows → 2 × 26 ≈ 52 screws

Total: ~180 screws + 180 wall plugs + 180 penny washers

Add a 20% safety margin:

Pack 220–240 plugs, screws, and washers.

Screw sizes to include

• 150 × 5.0 × 70 mm screws (for plywood/OSB)

• 100 × 5.0 × 100 mm screws (for thick or warped fence panels)

---

3. Additional Structure-Saving Items to Include

1. Heavy-duty straps or ratchet straps

• Useful for wrapping around large panels or awkward openings.

• Also allows securing fence panels without relying solely on screws.

2. Timber battens (optional but helpful)

• 25×50mm or 38×63mm battens

• Can be screwed over the top of panels to clamp them tightly to the wall

• Great for fence panels which may flex or split

3. Silicone or exterior caulk

• For sealing large air gaps where wind might get behind a panel.

4. Spare pilot screws

• Small screws (e.g., 4.0 × 40mm) to temporarily hold panels in place before the main fixings go in.

5. Battery backup & chargers

• Fully charged spare drill batteries

• A manual screwdriver in case power tools fail

6. Weatherproofing

• Exterior-grade tarp for emergency covering

• Sandbags or water-weight bags to reduce uplift around doors

4. Using Garden Fence Panels as Emergency Boarding (when materials sell out)

Fence panels are not ideal but can work in emergencies if reinforced.

Tips:

1. Remove the decorative slats if possible—use the solid frame.

2. Pre-drill through the thicker frame sections only.

3. Use longer 100 mm screws.

4. Add battens across the back to stiffen weak areas.

5. Use straps if the panel is too large to safely screw in many points.

Fence panels can catch the wind like a sail—so prevent gaps on all sides.

5. Full Recommended Emergency Hardware Kit (UK)

• 240 × wall plugs (brown/blue heavy-duty)

• 150 × 5.0 × 70 mm exterior screws

Below are three printable items you can copy/paste into a document and print:

1. A checklist,

2. A per-window calculation sheet,

3. A simple screw-spacing diagram (ASCII printable).

To help with clarity, I’ve also added small image groups for visual reference near the diagram section — these won’t interfere with printing if you copy only the text.
