How to Insulate Your House for Winter

As winter approaches, staying warm and cosy at home doesn’t have to mean skyrocketing energy bills.

With the right insulation strategies, you can create a comfortable living environment while also saving on energy costs.

But how do you achieve this in a budget-friendly way?

Let’s dive in and discover How to insulate your house for winter together.

Key Takeaways

  • Draught proofing using materials like foam strips and draft excluder brushes for doors and windows, and incorporating insulation around loft hatches are cost-effective measures to reduce heat loss and save energy.
  • Wall insulation, through techniques like cavity wall insulation, internal, and external wall insulation, is critical to retaining heat, with the potential to save hundreds per year on heating bills and improve your home’s thermal performance.
  • Insulating lofts, floors, and hot water systems are essential in preventing heat escape and can lead to substantial savings on annual energy costs, while double glazing and smart heating controls further conserve energy and reduce bills.

Sealing Against the Chill: Draught Proofing Essentials

Draught Proofing Windows

If you’ve ever felt a chill in your house despite having the heater on, drafts might be to blame.

When cold air seeps into your home through gaps around doors and windows, it can make your living space uncomfortable and increase your heating bills.

As such, draught proofing is a critical first step in insulating your home for winter.

It’s a cost-effective way to reduce heat loss, save energy, and make your home feel warmer at lower temperatures.

Common materials for draught proofing include foam strips, draft excluder brushes, and chimney balloons.

These materials are designed for easy installation, allowing you to effectively seal gaps and enhance your home’s insulation without breaking the bank.

Keeping Out the Cold: Doors and Windows

Doors and windows are typically the largest contributors to drafts in your home.

Insulating these areas can significantly reduce heat loss, lower your energy bills, and make your home feel warmer.

One effective strategy is to use self-adhesive foam tape for draught-proofing windows, which can help reduce energy consumption.

Another innovative measure is the use of thermal curtains and blinds.

By keeping curtains closed or investing in thermal curtain lining, you can reduce heat loss by up to 25%, ensuring your home is properly insulated.

During the day, keeping curtains open can allow sunlight to naturally heat the room, reducing the need for additional insulation.

Plush excluders can also be used to minimise the draft between rooms when positioned in front of a door, further enhancing your insulation efforts.

Loft Hatch Insulation: A Small Step for Big Savings

Addressing less obvious sources of drafts, like loft hatches, can significantly improve your home’s insulation.

Loft hatch insulation involves:

  • Incorporating insulating materials like strips and polystyrene slabs into the loft hatch
  • Eliminating drafts
  • Improving the overall insulation of the home.

This can be achieved by:

  • Installing draught strips around the frame to seal gaps
  • Adding a polystyrene slab to the door for extra insulation
  • Gluing a plastic bag to the hatch and filling it with insulating material
  • Cutting blanket insulation to the hatch’s size and affixing it accordingly

Fortifying Your Home’s Shell: Wall Insulation Techniques

External wall insulation process

Beyond draught proofing, wall insulation is another key factor to consider when looking to insulate your home.

Wall insulation is critical in retaining heat in your home, as about one third of the heat loss in an uninsulated home escapes through the walls.

There are two primary categories of wall insulation commonly used in residential properties: cavity wall insulation and solid wall insulation.

Cavity wall insulation, which is used in cavity walls, can potentially save up to £250 per year on heating bills, providing a cost-effective method for enhancing energy efficiency.

On the other hand, despite a higher initial cost, solid wall insulation is a worthwhile long-term energy-saving solution, potentially saving up to £460 per year.

The Barrier Within: Internal Wall Insulation

Internal wall insulation, which entails adding insulation boards or stud walls to your home’s interior, creates a thermal barrier that helps retain warmth.

This method of thermal insulation is effective in reducing heat loss, which in turn can significantly reduce your energy costs.

There are various internal wall insulation techniques, such as:

  • Using batts, slabs, or rolls of insulation made from mineral wool or sheep’s wool
  • Fitting rigid foam boards of insulation
  • Building a stud wall filled with insulation material
  • Using insulated plasterboard

By opting for internal wall insulation, you can potentially save up to £415 per year on energy costs.

Wrapping Up Warmth: External Wall Insulation

External wall insulation, on the other hand, involves:

  • Affixing a layer of insulation to the outside of a wall
  • Improving thermal performance
  • Reducing heat loss
  • Potentially enhancing the appearance of your property.

Commonly used materials for external wall insulation include expanded polystyrene (EPS), wood fibre board, and various foam panels like phenolic, polyurethane, and polyisocyanurate.

Opting for external wall insulation offers several advantages over internal options, including improved resistance to environmental factors, energy savings, reduced fuel costs, enhanced thermal retention, and potential increase in property value.

It can also enhance your property’s curb appeal by concealing older, less attractive walls and providing the opportunity to rejuvenate your home’s exterior with a range of finishing options.

Loft Insulation: The Topmost Shield

Installation of loft insulation

Another important area to consider for insulation is the loft.

Loft insulation is crucial because a significant amount of heat in a home can escape through the roof.

By insulating the loft, you can prevent a substantial portion of this heat loss, reducing up to 40% of the overall heat loss in a home.

Recommended materials for loft insulation include mineral wool, fibreglass, and polyurethane products.

It’s important to lay insulation with no gaps, use two layers for the best effect, and ensure materials comply with the recommended depths of 270mm or an overall thickness of 30 cm.

By installing loft insulation, you can see significant annual savings on your energy bills, making it a worthwhile investment for both semi-detached and detached houses.

Groundwork for Warmth: Floor Insulation Strategies

Floor insulation for wooden floors

Though often overlooked, floor insulation plays a crucial role in creating a warm and comfortable home.

It serves to maintain warmth within a property by preventing heat from escaping through the ground, potentially saving around £50 per year and reducing draughts.

Insulating different types of floors requires different methods.

For newer homes with concrete floors, rigid insulation boards can be added when replacing the floor.

Suspended timber floors in older homes can be insulated by lifting the floorboards.

Mineral wool insulation is then laid and supported by netting between the joists.

Thermal blankets or mineral wool are suitable for suspended floors and can potentially save up to £120 a year.

Rigid floor insulation is appropriate for concrete floors and can offer annual savings ranging from £35 to £95.

Pipe Dreams: Insulating Hot Water Systems

Insulating hot water pipes and tank

Don’t forget about insulating your hot water systems, it’s another significant aspect of home insulation.

By insulating hot water pipes and tanks, you can prevent heat loss, improve efficiency, and lower heating costs.

There are effective materials for pipe insulation in hot water systems, such as polythene or neoprene foam for electric water heaters and PVC pipe sleeves or recycled fibreglass pipe wrap for older systems.

The installation cost of a hot water cylinder jacket is relatively low, making it an affordable measure towards improving home heating efficiency.

Clear View to Efficiency: Double Glazing and Secondary Glazing

Double glazing and secondary glazing are also practical strategies for insulation.

These methods can reduce heat loss through windows, improving energy efficiency and comfort in your home.

Secondary glazing is less effective than double glazing in preventing heat loss, but it can be a more cost-effective alternative until double glazing is a viable option.

Double glazing units are made up of two layers of glass with an inert gas in between to minimize heat transfer, while secondary glazing entails an extra pane of glass or plastic installed inside the window.

Before installing double glazing, it’s advisable to consult with a local council planning officer to explore the available options and understand any regulations or restrictions.

Heating System Savvy: Smart Controls and Maintenance

To optimise your heating system’s performance, consider smart controls and regular boiler maintenance.

By regulating the temperature in each room, smart heating controls like thermostatic radiator valves (TRVs) and smart thermostats can help conserve energy and reduce costs.

Upgrading your thermostat can lead to greater accuracy in thermostat to boiler communication and prevent energy wastage, resulting in cost savings.

This upgrade is essential in optimising heating system performance.

On top of that, improving radiator performance through the use of TRVs and bleeding radiators to remove trapped air can ensure efficient heating.

The Furnishing Factor: Decor that Retains Heat

Even your home decor can play a part in retaining heat.

Elements such as thermal curtains, woollen rugs, and even the placement of your furniture can affect heat retention and create a cosy atmosphere in your home.

Adding extra layers in your home, such as throws, bedspreads, and insulated underlay for flooring, can save up to 15% on energy bills while providing additional warmth.

The placement of furniture can also impact heating efficiency.

When furniture is placed against radiators, it hinders the circulation of warm air, leading to inefficiency in heating and affecting the overall temperature of the room.

Navigating Regulations and Grants

Finally, be aware of any regulations and grants related to insulation improvements.

This can help you make informed decisions and access financial assistance for energy-saving measures.

Grants are available for low-income households and those in receipt of certain benefits through the Energy Company Obligation (ECO) scheme.

Details about these grants can be found on the Simple Energy Advice website and through the Warm Home Discount program.

Trusted installers for insulation can be found through the National Insulation Association (NIA) website or the Trust Mark website.
