Internal Wall Solutions

Typically consists of either dry lining in the form of flexible thermal linings available in 1 metre by 12.5 metre rolls, laminated insulating plasterboard (known as thermal board), or built-up systems using fibrous insulation such as mineral wool held in place using a studwork frame.

1) Dry lining in the form of flexible thermal linings

• Sempatap Thermal from Mould Growth Consultants Ltd is a product specifically developed for energy conservation often referred to as 'magic wallpaper' or 'flexible insulating lining‘ which substantially reduces heat loss making room feel warmer. The lining is 10mm thick and supplied in rolls one metre wide x12.5 metres long. The material is made from a natural product - latex - in an open and closed cellular construction and has a durable fibreglass face that can be decorated with emulsion, wall paper or tiled.

2) Laminated insulating plasterboard

• Fermacell Partition with steel subframe, with insulating material from A. Proctor Building Products Ltd is a high performance multi-purpose building board, that when installed combines the properties of solid blockwork with the speed and flexibility of conventional drywall techniques
• Kingspan Insulation Plasterboards
  The internal wall insulation solutions from Kingspan Insulation are a premium performance, CFC/HCFC-free rigid phenolic insulant laminated to 12.5 mm plasterboards. The product has a Class O fire rating/Low Risk.
• Knauf Polyfoam Linerboard is a high performance board from Knauf Insulation that has extruded polystyrene bonded to a 9.5mm plasterboard. The product comes in a variety of thicknesses to achieve different levels of carbon saving and can be fixed easily to solid wall properties.

3) IWI System

• The Knauf Internal Wall Insulation System (IWI) has been specifically designed for Solid Wall properties. It comprises of an insulated EcoStud that eliminates cold bridging and can be fixed directly to the substrate. The studs are then filled with A+ Green Guide Rated EcoBatts. The system is then finished with a 12.5mm Vapourshield.

Survey & quality monitoring

A quality inspection will be carried out according to industry best practice.

• A survey of the property is required to assess the suitability of the substrate and assess any ancillary work required
• Supervision will vary depending on the system
• Low level of supervision required with most systems
• Contact your local installer for more details and FREE survey of your property!

External Wall Solutions

What is External Wall Insulation?

• A method of upgrading the thermal performance and external appearance of existing properties
• Insulated and rendered properties are transformed into warm, energy efficient and attractive homes/buildings

After	Before

External Wall Insulation – Key Components

Surveys

• Properties need to be fully surveyed
• Is substrate suitable for mechanical fix?
• Is there sufficient overhang on cills/soffits?
• Gates/satellite dishes, a provision needs to be made for refix
• Are windows and reveals suitable?
• Do soil pipes need to be moved?

Installation

• 3 key stages for a typical semi
  • 1) Boarding and beading 1-2 days
  • 2) Base coat and Mesh 2 days
  • 3) Top coat /finish 1days
• Usually a 3 man team
• Drying times required for stage 2 up to 48hrs
• Can only be applied if temp is 5 degrees and rising

Survey & quality monitoring

A quality inspection will be carried out according to industry best practice.

• Varies from system to system but will normally take place at the 3 critical stages
• Under CERT independent inspections will also be required
• Contact your local installer for more details and FREE survey of your property!
