Statistically loss in your home occurs through:
- 30-35% Roof
- 21-31% Windows
- 18-25% Walls
- 12-14% Floor
- 6-9% Air leakage
Obviously the *best* way to insulate your home is to have batts or blankets installed in your ceilings, walls, and underfloor. If you are a home owner there are grants and loans available through the Hawke’s Bay Regional Council to help with this.
Windows (and doors)
Windows account for a huge amount of heat loss, and here are some ways to help:
- Check window and door frames -In daylight shut doors and windows and check for gaps (daylight)
- Self adhesive foam or v-strip around doors and windows. It is important to choose the correct product and size i.e v-strip for wooden windows – especially sash windows – this not only stops draughts but stops ‘window rattle. Foam on aluminium. If in doubt check with your local Hardware Merchant.
- Use draught stops – these are easy to make and effective around doors and ranch sliders.
- Install purpose made ‘weather strips’ to the bottom of doors
Draught stops – Get crafty – old jeans stuffed with rice or fabric scraps.
- Add a layer to your existing curtains: Either joosh up by bright new fabric over the top of old or add a lining. Such as Ashley’s amazing idea of adding a cheap fleece blanket to the back of your curtains. (Really effective)
- Make sure your curtains fit – wider and longer than your windows works best
- Pelmets will also stop heat escaping
- Double glazing reduces heat loss, noise and UV light. there are plenty of retro-fitting options including DIY products. Bubble wrap can also be used.
Other ways you can lose heat
- Gaps around skirting and architraves: Check for gaps by running your hand around the skirting boards/floor boards and check for draughts or use a candle or and incense stick, watch the flame or smoke for air movement. Seal gaps as you find them.
- Install metal covers over keyholes or leave the key in the door
- Make sure your ceiling hatch fits properly
- Insure electrical outlets on wall are firmly in place
- Block unused chimneys and fireplaces. Open fireplaces are inefficient and draughty. Replace with a built in wood or pallet fire If you do not use the fire, block the chimney completely.
- Check for gaps between floorboards on wooden floor. Under the house at night to see if light is shining through
- Repairing holes in the floor: From under the house screw a small square of timber over the hole. Cut a bung to fit snugly in the hole and jam it in from the top. Tap in with a hammer gently. Sand. Fill any gaps with wood filler. Consider Plastic sheeting under the house as this blocks dampness from rising
- Open down lights can let in draughts – replace with sealer canister types.
Hot Water Cylinders
Hot water cylinders – A grade cylinders give the best insulation – Savings $80 per year.
If cylinder is warm to the touch then covering will reduce heat loss. Insulating hot water pipes also helps reduce heat loss.
When warm moist air touches a cool surface (such as a window) the moisture condenses into water. You can reduce condensation by reducing the amount of moisture in your home.
- Drying washing inside
Some tips on Heat Pumps:
