ThermaSeal — Spray Foam Insulation
High-performance insulation

Keep the heat inside.

And your heating bills down. Professional spray foam insulation creates a continuous thermal barrier that helps your home retain the warmth you're already paying for.

Fast installation Seamless coverage Long-lasting insulation
Thermal barrier Heat stays.

Better insulation means less energy escaping through weak spots.

✓ Awkward gaps covered
The hidden problem

Your home could be losing more heat than you think.

You turn the heating up. The house gets warm. Then the temperature starts dropping again. The problem may not be the boiler — the heat could simply be escaping.

You're paying to heat air that doesn't stay inside.

Roofs, lofts, gaps and poorly insulated spaces allow valuable warmth to escape. Better insulation helps reduce heat loss and creates a more comfortable home.

Less heat escaping. Less energy wasted. More comfort inside.

The cycle of wasted heat.

1Heating warms the house.
2Warm air reaches weakly insulated areas.
3Heat escapes through gaps and roof spaces.
4The heating has to replace it again.
Why spray foam?

No awkward gaps. No forgotten corners.

Spray foam expands during application, reaching difficult areas and creating a continuous insulating layer around beams, corners and structural elements.

Lower Heat Loss

Keep more of the warmth you're already paying for inside your home.

Fewer Draughts

Fill difficult gaps and create a more continuous insulating layer.

Better Comfort

Enjoy more consistent indoor temperatures during colder months.

Long-Term Performance

Properly installed foam is designed to retain its structure over time.

Fast Installation

Many residential projects can be completed quickly with limited disruption.

Hard-to-Reach Coverage

The foam expands into areas that can be difficult to insulate traditionally.

Energy stays where it belongs

Stop paying to heat the outside.

Every time warm air escapes through a poorly insulated roof or loft, your heating system has to replace it. Better insulation helps your home hold onto the energy you're already using.

Less unnecessary heat loss A warmer-feeling home Reduced demand on your heating system Improved energy efficiency Greater year-round comfort

Applications

Where can spray foam insulation be used?

From lofts and complex roof spaces to outbuildings and commercial structures, spray application can adapt to many difficult surfaces.

Lofts & Attics

Create a continuous thermal layer beneath the roof and help reduce upward heat loss.

Roof Spaces

Reach complex shapes and awkward gaps that are difficult to cover with traditional materials.

Timber-Frame Homes

A flexible solution that can closely follow the structure of timber-frame construction.

Walls

Improve thermal performance by insulating suitable wall structures and cavities.

Garages & Outbuildings

Make workshops, garages and other buildings more comfortable and easier to heat.

Commercial Buildings

Warehouses, workshops and larger buildings can benefit from fast spray application.

Before / After

From cold loft to continuous insulation.

Traditional insulation can leave weak spots. Spray foam is designed to form a more complete layer across awkward structures.

Before

Heat finds the weak spots.

Uneven insulation Hard-to-reach gaps Draughts Heat escaping Cold surfaces Higher heating demand
After

A more complete thermal barrier.

Continuous insulation Awkward spaces covered Reduced air leakage Better heat retention More consistent comfort Improved thermal performance
Simple process

One day can make a big difference.

For many properties, improving insulation doesn't require weeks of renovation. The process can be surprisingly straightforward.

Customer feedback

Don't just take our word for it.

Clear communication, tidy work and homes that feel more comfortable after installation.

★★★★★
“The difference upstairs was noticeable almost immediately.”

Our loft used to become freezing in winter. The team completed everything in a day and left the place spotless.

— James R.
★★★★★
“Clear quote and no surprises.”

Everything was explained beforehand, the team arrived when promised and the job was completed exactly as agreed.

— Sarah M.
★★★★★
“The house holds its temperature much better now.”

We contacted them because of the cold bedrooms upstairs. Really pleased with the result.

Thermal assessment

Is your loft letting heat escape?

A thermal assessment can reveal areas where your property is losing heat and help identify where insulation improvements could make the biggest difference.

Instead of guessing where the problem is, find it.

Frequently asked questions

What homeowners usually want to know.

Every building is different, so final recommendations should always be based on the property itself.

It depends on the size and complexity of the property, but many residential projects can be completed within a short installation window.

Potentially, yes. The construction, condition, ventilation and moisture characteristics should be assessed before installation.

No insulation method is right for every building. That's why the property should be assessed first.

This depends on where the work is carried out and the product used. The appropriate safety procedure should be explained beforehand.

Properly specified and installed spray foam is designed as a long-term insulation solution.

Yes. Spray foam can also be suitable for warehouses, workshops, agricultural buildings and other commercial structures.

Your house is already producing the heat. Help it keep it.

A warmer home doesn't always need a bigger boiler or higher thermostat. Sometimes, it simply needs better insulation.
