How do we stay warm with no insulation?

Staying Warm After Spray Foam Removal: Essential Winter Advice While Your Home Recovers

Thousands of UK homeowners are now being told to remove spray foam insulation due to mortgage difficulties, roof ventilation problems and updated government guidelines. If you’ve recently removed spray foam from your loft, you’ve taken the right first step toward restoring your property’s long-term health and mortgageability.


But we also understand the worry:


“How do I keep my home warm and my bills manageable while the insulation is gone?”


The truth is this:


Your home needs a minimum of six months to settle, dry, and recover after spray foam removal.
During this period, you should not reinstall new insulation in the rafters or roof space.

This article explains:

  • Why the cooling-off period is essential
  • How to keep warm efficiently and safely
  • How to reduce energy bills without damaging the recovering roof
  • What simple habits, free tricks and low-cost upgrades make the biggest difference
  • What to do when you're finally ready to choose a new, safe insulation system


Our aim is to help you keep comfortable without compromising the structural recovery of your property.


Why Your Home Needs a 6-Month Cooling-Off Period


After spray foam is removed, the roof structure needs time to:

  • Dry naturally
  • Equalise moisture levels
  • Release trapped humidity
  • Stabilise the rafters and timbers
  • Allow any hidden damp patches to reveal themselves
  • Restore normal ventilation conditions


Re-insulating too quickly — especially with modern foils or rigid boards — risks:

❌ Trapping moisture again

❌ Causing cracking, twisting or timber stress

❌ Masking roof problems instead of allowing them to show

❌ Repeating the exact issues that caused lenders to reject the foam in the first place


This temporary “bare loft” period is essential. It protects your roof and ultimately protects the value of your home.


How to Stay Warm & Reduce Bills During the Cooling-Off Period


Here are the most effective ways households can stay comfortable without roof insulation while their home recovers.


1. Follow the 4pm Curtain Rule


As days get shorter, heat lost through windows increases dramatically — especially without loft insulation to compensate.

A simple daily rule helps:

  • Open curtains in the morning to let in sun and natural warmth
  • Close all curtains at around 4pm, or roughly 15–20 minutes before sunset
  • Adjust earlier as the month progresses


This traps warmth inside and stops cold air falling into the room from the glass. Think of curtains as temporary insulation for your windows.

If possible, use:

  • Thermal curtains
  • Fleece-lined curtains
  • Curtains that overlap the frame to block draughts


Even adding a cheap, fire-safe fleece layer to existing curtains can make a difference.


2. Heat the House Strategically — Not Everywhere at Once


While your loft is temporarily uninsulated, central heating may feel less efficient. Instead of raising the thermostat, focus on:


Heat the human, not the whole home


Great for times when you're sitting still:

  • Heated throws
  • Warm layers
  • Hot water bottles
  • Thick socks or thermal slippers
  • Warm drinks
  • Portable personal heaters (used safely and only when needed)

Running a whole-house heating system to warm two people watching TV is simply unnecessary.


Heat only the rooms you are using..


Use TRVs (thermostatic radiator valves) strategically.

Keep unused rooms cool but not freezing — a small background temperature prevents damp.


3. Bleed Radiators and Check Heating Efficiency


With insulation removed, every percent of boiler efficiency matters.

Bleed radiators to remove trapped air.

Cold tops or patchy heating = wasted energy.

A properly bled system:

  • Warms faster
  • Uses less fuel
  • Feels more comfortable


A radiator key costs around £2.



4. Loft Floor Insulation (But NOT the Rafters)


During the cooling-off period, you can safely use loft floor insulation only — such as mineral wool rolls laid on the joists.

This:

  • Does not interfere with roof ventilation
  • Avoids trapping moisture
  • Provides basic warmth without affecting roof drying
  • Is fully removable when it’s time to choose your long-term solution


We often recommend this temporary step to our customers.


5. Install a Hot Water Cylinder Jacket


A hot water cylinder without insulation loses heat rapidly.

A simple jacket:

  • Costs around £20–£30
  • Saves up to £150–£200 a year
  • Reduces boiler workload
  • Keeps water warmer for longer
  • Is easy to install


This is one of the cheapest and most effective ways to cut bills during your recovery period.


6. Check for Draughts — They Matter Even More Now


When roof insulation is temporarily missing, draughts seem worse.

Check:

  • Gaps around doors
  • Window seals
  • Letterboxes
  • Floorboards
  • Loft hatches


Use low-cost fixes like:

  • Draught excluders
  • Foam strips
  • Brush seals
  • Keyhole covers
  • Loft hatch insulation pads


A few pounds spent here can save far more in heating costs.


7. Improve Ventilation to Prevent Damp


This is critical after spray foam removal.

Moisture inside your home will naturally rise into the loft.

Without insulation blocking airflow, that moisture must escape — not condense.

Use controlled ventilation, such as:

Stoßlüften (Shock Ventilation) Method


A German technique:

  • Open windows fully for 5–10 minutes twice a day
  • Allow moist air to escape rapidly
  • Replace it with cold but dry air


This prevents mould, stops condensation, and helps your roof timbers dry naturally.

Do NOT leave windows slightly open all day — that cools the house unnecessarily.


8. Avoid Drying Clothes Indoors Wherever Possible


Drying laundry inside releases up to nine pints of moisture into your home.

Without insulation in the loft, this moisture can rise and delay the drying process of your roof timbers.

If you must dry indoors:

  • Use a dehumidifier
  • Keep the room closed off
  • Ventilate afterwards using the shock method


When the 6 Months Are Up — What Happens Next?


After your home has completed its cooling-off period, you can safely consider long-term insulation options.

Final Message to Homeowners


Removing spray foam can feel stressful, and temporarily losing loft insulation can be worrying — especially in winter. But with the right daily habits, small upgrades and good ventilation, you can stay warm, reduce energy costs and keep your property healthy while it recovers.


This cooling-off period is temporary.


The long-term security of your home is permanent.

As the spray foam insulation crisis continues to affect homeowners across the UK, many people are only now discovering that they may have important legal protection under Section 75 of the Consumer Credit Act 1974. For some homeowners, this protection could prove financially life-changing. Why? Because if even part of the original spray foam installation was paid for using a credit card, homeowners may have the right to pursue claims not only for the installation itself — but potentially for associated losses, including costly removal work. At a time when many families are facing failed mortgage applications, equity release refusals, and expensive remediation bills, understanding Section 75 has become critically important. What Is Section 75? Section 75 of the Consumer Credit Act is a UK consumer protection law that makes credit card providers jointly liable for breaches of contract or misrepresentation by a retailer or service provider. In simple terms: If a company sold a product or service under misleading circumstances, and part of the payment was made using a credit card, the credit card company can also be held responsible. This protection applies even if: The company has ceased trading The installer refuses to help The warranty is worthless The homeowner only paid a deposit on the credit card Many consumers wrongly believe the entire balance must have been paid by credit card. That is not true. In many cases, paying just the initial deposit or first payment via credit card may be enough to trigger Section 75 protection. Why This Matters for Spray Foam Insulation Thousands of homeowners claim they were sold spray foam insulation without proper warnings about: Mortgage restrictions Lending refusals Future saleability concerns Ventilation risks Timber inspection limitations Potential removal costs Many homeowners state they were assured: “Mortgage lenders have no issue.” “The product is fully approved everywhere.” “It adds value to your home.” “It is completely safe for future buyers.” Years later, some are discovering: Their property is down-valued Equity release applications are declined Buyers cannot obtain mortgages Surveyors are flagging the roof structure Removal costs can exceed tens of thousands of pounds This is where Section 75 may become highly significant. Removal Costs May Also Form Part of a Claim One of the most important points homeowners should understand is this: Potential claims may not be limited solely to the original installation cost. If the product was misrepresented or sold without proper disclosure of foreseeable consequences, consequential losses may also be considered. This can include: Spray foam removal costs Roof timber inspection costs Surveyor reports Associated remedial works Financial losses linked to failed transactions Every claim is fact-specific, and outcomes vary, but legal and financial experts increasingly recognise that removal costs may form a substantial part of consumer claims where remediation becomes necessary to restore mortgageability. For homeowners now facing enormous removal bills simply to sell or refinance their homes, this aspect of Section 75 could be critical. The Key Requirement Many People Do Not Realise To qualify for Section 75 protection, one of the most important conditions is that at least part of the transaction must have been made directly using qualifying credit. In many spray foam cases, homeowners paid: The initial deposit by credit card Follow-up balances via bank transfer Finance agreements Debit cards Or cash The crucial point is this: If the first payment or deposit was made on a qualifying credit card, protection may still apply for the full contract value — not merely the deposit amount. This is one of the most misunderstood areas of consumer law. Homeowners Should Gather Evidence Immediately If you believe your property may be affected, it is important to begin collecting documentation as early as possible. Useful evidence may include: Original invoices Credit card statements Finance agreements Installation contracts Sales brochures Emails and WhatsApp messages Mortgage refusal letters Surveyor reports Removal quotations Guarantees and warranties Advertising claims made at the time of sale The stronger the documentary trail, the stronger the potential claim position may become. Time Is Important Many homeowners delay taking action because they assume: “Nothing can be done.” “The installer has disappeared.” “The warranty is useless.” “The problem is too old.” However, Section 75 protections can sometimes extend far beyond standard warranty periods. Each situation depends on individual facts, dates, and legal considerations, but homeowners should not automatically assume they have no options available. Awareness Could Save Homeowners Thousands For many families, spray foam insulation has become far more than an insulation issue. It has become: A lending issue A property value issue A retirement issue And in some cases, a financial survival issue Understanding Section 75 may offer an important pathway for homeowners facing unexpected financial harm linked to spray foam installations. The key message is simple: If you paid even part of the installation using a credit card, you may have more rights than you realise.
