Why Winter-Proofing Your Modular Home Matters
Winter-proofing ensures that modular homes remain warm, energy-efficient, and low on bills during the colder months. Since modular homes are often smaller and built differently from traditional housing, proper insulation and heating strategies are vital for comfort and reducing utility bills.

1. Prioritise High-Quality Insulation

Insulation is your first line of defence against cold temperatures. Well-insulated walls, roofs, and floors reduce heat loss and maintain indoor comfort.
Recommended Insulation Materials
- Spray Foam Insulation – Provides excellent thermal resistance and seals gaps effectively.
- Fibreglass Insulation – Cost-effective and widely available for walls and ceilings (To be handled strictly by professionals!!).
- Rigid Foam Boards – Ideal for flooring and foundations, offering high insulation value.
2. Seal Gaps and Cracks

Even small gaps around windows, doors, and vents can let cold air seep in. Draught-proofing ensures your home remains snug and reduces heating costs.
Steps to Seal Gaps
- Use weatherstripping around doors and windows.
- Apply silicone sealant to cracks and joints.
- Install a door sweep to block under-door draughts.
- Inspect and seal around plumbing and wiring penetrations.
3. Invest in Energy-Efficient Heating Systems

Efficient heating systems save money and ensure consistent warmth during winter. Modular homes, with their compact design, benefit from tailored heating solutions.
Top Heating Options
- Air Source Heat Pumps – High Initial cost, but the savings over time can be very attractive.
- Underfloor Heating – Provides even heat distribution.
- Electric Panel Heaters – Quick to install and effective for smaller spaces.
- Wood-burning Stoves – Add charm and warmth to living spaces, and wood and coal are relatively cheaper to burn.

4. Upgrade to Double or Triple-Glazed Windows

Windows can be a significant source of heat loss. Upgrading to double or triple-glazed windows enhances insulation, reduces condensation, and improves energy efficiency.
Benefits of Double & Triple Glazing
- Reduces heat loss by up to 30%.
- Reduces external noise.
- Helps maintain indoor temperatures.
5. Install Thermal Curtains and Blinds

Thick, thermal curtains act as an additional layer of insulation, trapping heat inside your modular home.
Tips for Using Thermal Curtains
- Close curtains before sunset to retain heat.
- Choose floor-length curtains for maximum coverage.
- Use blinds with thermal backing for added insulation.
6. Don’t Forget Floors and Rugs

Modular homes often feature lightweight flooring, which can lead to heat loss. Adding rugs or carpets is a practical and stylish way to combat this.
Benefits of Rugs
- Adds a layer of insulation to cold floors.
- Creates a cosy and inviting atmosphere.
- Reduces noise within the home.
7. Maintain Proper Ventilation
While sealing gaps is crucial, maintaining good ventilation is equally important to avoid condensation and mould. Use controlled ventilation systems like heat recovery ventilators (HRVs) to retain warmth while ensuring fresh air circulation.
8. Add External Cladding for Extra Protection
This one requires a high initial cost, so you won’t need this unless you have a couple thousand euros lying around. External cladding not only improves the appearance of your modular home but also acts as a barrier against wind and rain.
Popular Cladding Materials
- Timber for a natural look.
- Composite panels for durability.
- UPVC for affordability and weather resistance.
Cost Comparison Estimates of Heating and Insulation Upgrades***
| Upgrade | Approximate Cost (€) | Estimated Savings (€ per year) |
|---|---|---|
| Double/Triple Glazing | 5,000 – 10,000 | 200 – 400 |
| Loft Insulation | 1000 – 1500 | 100 – 250 |
| Air Source Heat Pump | 6,000 – 10,000 | 300 – 600 |
| Draught-proofing | 50 – 200 | 50 – 250 |
***The estimates are from various online sources for a 3-4 bedroom house. Prices may vary greatly according to suppliers.
