The problem we solve
Is your home cold, hard to heat, or expensive to keep warm?
Cold walls. Condensation. Higher energy bills. Rooms that never seem to feel properly warm.
These are often signs that your home is losing heat where it should not. In older properties, the right answer may be external wall insulation. In cavity-wall homes, or where most of the heat is escaping through the loft, another improvement may be the better option.
Before spending money, it is worth making sure you are solving the right problem. That is why Rockwarm looks carefully at where the heat is escaping and helps you choose the improvement that makes the most sense for your home.
Compare your insulation options
Compare the options, then book a survey if you would like help choosing the best next step for your home.
The result
A warmer, more comfortable home that costs less to run.
Warmer walls
Rooms feel warmer and more comfortable, without that cold-touch feeling.
Lower energy bills
Keeping heat in for longer can help reduce the energy needed to warm your home.
A smarter finish outside
External wall insulation can also give older brickwork a cleaner, more refreshed appearance.
What we do
We help homeowners choose the right insulation and energy saving solutions for their home.
External Wall Insulation
Our signature service for solid-wall and hard-to-heat homes. It reduces heat loss, tackles condensation, and transforms the outside of the property at the same time.
Cavity Wall Insulation
A fast, cost-effective solution for suitable cavity-wall properties. Ideal when you want a practical thermal upgrade without changing the appearance of the house.
Loft Insulation
Often the quickest win for energy savings. A straightforward way to stop heat escaping through the roof and improve comfort throughout the home.
