Dry Lining Interior Insulation

Warm up your home from the inside out.

If your home has solid walls and feels hard to heat, dry lining (also called interior or internal wall insulation) is a smart and effective solution. This method involves fitting insulated plasterboard to the inside of your external walls, significantly reducing heat loss and improving comfort all year round.

What Is Dry Lining Insulation?

Dry lining is a method of interior wall insulation using insulated plasterboards, often referred to as warm boards. At Complete Insulations, we install insulated warm boards, which combines a rigid EPS phenolic or polyurethane with plasterboard for high thermal performance. These boards help retain heat, lower your energy bills by up to 50%, and improve overall home comfort.

Is Dry Lining Right for Your Home?

Dry lining is ideal if:

  • Your home has solid walls (common in houses built before the 1960s).
  • You’re renovating your home and want to upgrade insulation at the same time.
  • You want to preserve the external appearance of your property.
  • You’re looking for a quicker, more affordable alternative to external wall insulation.

Solid walls can lose up to 30% of your home’s heat—dry lining helps stop that heat loss in its tracks.

Will It Prevent Damp?

Yes—interior insulation can help prevent penetrating damp (but not rising damp). If your home already shows signs of damp, we can often address this as part of the insulation process. Where a faulty damp-proof course is the issue, we’ll help arrange specialist treatment prior to installation.

Dry lining also includes a vapour control layer, reducing the risk of internal moisture reaching your walls and promoting a drier, healthier home.

How Effective Is It?

It’s a smart investment that adds long-term value and comfort to your home.

Dry lining improves your home’s energy efficiency by:

Reducing

Thermal conductivity
(the rate at which heat escapes)

Increasing

Your home’s R-value
(resistance to heat transfer)

Creating

A warmer, more stable indoor temperature with less heating

Will It Disrupt My Life?

We know that having work done inside the home can be disruptive. That’s why we work efficiently, minimise mess, and aim to complete the work with as little impact on your routine as possible.

Dry lining produces no fumes and uses non-toxic materials, though it can create some dust. Most families stay in their homes during installation, but if you have small children or asthma, you may prefer to stay elsewhere temporarily.

What About Room Space?

Because dry lining is installed on the inside of your walls, it will reduce your internal floor space slightly. If space is a concern, we can advise whether external wall insulation may be a better option.
