Why Is Insulating Your Home a Good Idea?

• Lower energy costs: less heat loss means lower heating bills.
• Better comfort: fewer draughts, warmer rooms and less “cold floor” feeling.
• Lower CO₂ emissions: less energy use = smaller footprint.
• Higher home value: well-insulated homes are more attractive to buyers.

Where Does Your Home Lose the Most Heat?

In an average home, heat loss typically looks like this:

• Roof / attic: around 30%
• External walls: around 20%
• Windows: around 15%
• Floor: around 10%

That’s why attic/roof insulation is often the most effective first step if you want quick gains.

Recommended Tools & Products

Insulation is all about tight fitting (no gaps), secure fixing (frames and boards) and airtight sealing (tape + sealant). These tools make the job faster and cleaner:

Fixing & fastening (foil, membranes, trims)

• 18V Cordless Combi Tacker 18GA Ultra – for fast stapling of vapour barriers, membranes and foil to timber frames.
• 4V Combi-Tacker – compact option for lighter work and quick fixes.

Drilling & screwing (studs, battens, boards)

• 18V Cordless Drill – great for framing, battens and general screw work.
• 18V Drill Driver (without battery & charger) – same job, handy if you already have MAXXPACK.

Airtight sealing (gaps, edges, junctions)

• 18V Cordless Caulking Gun – for consistent beads along frames and edges.
• Maxxpush 6V Caulking Gun with LED Work Light – compact and super handy for detail sealing and indoor work.

How to Insulate an Internal Wall

Step 1: Install studs

Fix timber studs vertically. A common spacing is 60 cm centre-to-centre so insulation fits snugly and plasterboards line up cleanly.

Step 2: Seal gaps

Seal gaps between frame and wall. Small gaps can be sealed with silicone; larger gaps may need expanding foam or compressible tape.

Step 3: Fit insulation tightly

Measure carefully and cut insulation so it fits without compression. Avoid gaps and “open seams”.

Step 4: Install vapour barrier

Staple the vapour barrier to the frame and overlap seams by at least 10 cm. Tape every seam and repair small tears immediately.

Step 5: Fix plasterboard

Screw plasterboards onto the studs. Finish joints and edges as needed.

How to Insulate a Ceiling

Step 1: Level with battens

If beams aren’t perfectly level, use battens to create a straight base.

Step 2: Install insulation between beams

Cut insulation slightly oversized so it wedges in place. Avoid air gaps and keep layers tight.

Step 3: Add cross battens

Install battens perpendicular to beams for strength and to support plasterboards.

Step 4: Fix plasterboards

Screw boards on securely and keep fixing points consistent for a solid, crack-resistant finish.

How to Insulate an Attic Floor

Step 1: Vapour barrier (only if needed)

If the attic is unheated, install a vapour barrier foil on the floor first. Overlap seams by 5–10 cm and tape airtight.

Step 2: Place floor joists / battens

Place timber joists at 60 cm centre-to-centre (or 40 cm if the attic will be heavily used). Keep them level.

Step 3: Install insulation

Place insulation tightly between joists. Cut pieces about 1.5–2 cm wider so they wedge in and prevent thermal bridging.

Step 4: Finish with floor boards

Install underlayment or floor boards and screw down securely to create a usable attic floor.

Common Insulation Mistakes to Avoid

• Leaving gaps between insulation panels (heat escapes through the weakest points).
• Forgetting to tape overlaps and corners in the vapour barrier.
• Compressing insulation too much (reduces insulating value).
• Blocking ventilation openings (can cause moisture and mould issues).
