Internal Wall Insulation in Bridgend
Expert internal wall insulation treatment for properties in Bridgend, Bridgend. Eliminates cold walls — stops condensation at source. Free surveys with no obligation.
Bridgend has a wide range of housing types, but its older terraced housing — particularly in areas like Oldcastle and Nolton — regularly requires rising damp treatment, cavity wall tie replacement, and condensation remediation.
Internal Wall Insulation Treatment in Bridgend
Cold walls are one of the most common causes of condensation and black mould in UK homes — and one of the most expensive sources of heat loss. We install the Wykamol Isotherm Tiwi system — a high-performance orange internal wall insulation system that dramatically improves the thermal performance of cold external walls from the inside. The system raises the surface temperature of the wall above the dew point, eliminating the condensation that feeds mould growth, while significantly reducing heating costs. EverDry Damp installs the Wykamol Isotherm Tiwi system as a standalone service or alongside condensation treatment, damp proofing, or basement waterproofing works for a comprehensive solution.
Bridgend is a market town west of Cardiff with a mix of Victorian terraced housing, inter-war semis, post-war estates, and modern developments.

Frequently Asked Questions — Internal Wall Insulation in Bridgend
What is Isotherm insulation?
We use the Wykamol Isotherm Tiwi system — a high-performance orange internal wall insulation system with excellent thermal resistance values. A relatively thin installation delivers a significant improvement in wall U-values, raising the wall surface temperature above the dew point to eliminate condensation. It's ideal for internal retrofit where space is at a premium.
Will internal wall insulation reduce the size of my rooms?
The boards are thin — typically 25mm to 50mm depending on the required performance level — so the reduction in room size is minimal. In most rooms the improvement in warmth and the elimination of mould far outweighs the small reduction in floor area.
Will internal insulation solve my mould problem?
In most cases yes — if the mould is caused by condensation on cold walls, raising the wall surface temperature above the dew point stops condensation forming. This removes the moisture that mould needs to grow. We always treat existing mould before installing the insulation system.
Can Isotherm be installed alongside damp proofing?
Yes — and in many cases this is the best approach. Damp proofing addresses any structural moisture ingress first, then internal wall insulation is installed to improve thermal performance and permanently eliminate condensation. We can survey for both and provide a combined solution.
