High Performance Internal Wall Insulation Systems for Solid-Walled Properties

Cold and damp walls will always be at risk of mould and condensation. However, by making a wall warmer the risk can be lowered significantly. CK Walker Damp & Timbers can offer a number of different ways to achieve this using a range of products.


Rental Properties - Low EPC's

Recently many older solid-walled properties in the housing stock are now no longer legal for landlords to put up to rent. This is because current property rental regulations in the UK denote that only properties with an EPC (Energy Performance Certificate) rating of E or above are legally permitted to rent to tenants.


However, there are a number of insulation systems which can ensure your walls are thermally upgraded.


Stormdry EP Boards for Cold Walls


Stormdry EP Board is a new high-performance low-profile aerogel internal wall insulation board.


A 3 mm magnesium oxide plasterboard is lined with a 10 mm aerogel blanket that gives the board a high thermal resistance despite its 13 mm overall thickness. The board is also breathable, minimising problems with trapped moisture and interstitial condensation.




The boards are applied directly to walls using Stormdry EP Foam Adhesive. Once applied, skim plastering and decoration can be carried out using standard techniques.



U-value Reduction will save Heat & Energy


Calculations show that a successful application of the insulating board can provide a U-value reduction of up to 61% on a typical uninsulated solid wall, greatly reducing heat loss.


Combined Protection - Stormdry Masonry Protection Cream & Stromdry EP Boards


If Stormdry EP Board is applied on a previously damp solid wall that has been treated with Stormdry Masonry Protection Cream, an even bigger improvement in insulation performance and energy bill savings can be made. When used in combination the U-value of a solid wall in moved from 2.1 to 0.8 contributing to any upgrades in the properties EPC rating.

Stormdry EP Insulation Boards and Re-Plastering - Case Study (Little Eaton)

The walls in this toilet room were very cold even when the heating was on. We were asked to provide a solution to insulate the walls but not use up to much space. The perfect solution was to use Stormdry EP Boards as these offer excellent thermal properties and are very slimline therefore taking up very little space in comparison to other insulation boards.


The walls were first prepared by removing the paint and keying the surface. We then applied the Stromdry EPO boards using EP adhesive followed by applying EP primer to the surface of the boards. We then applied a plaster skim finish to a smooth finish followed by fitting new skirting boards.


This room will now be toasty warm.
