Superglass
Rolls, batts and slabs for applications including timber-frame walls, roofs, lofts and acoustic insulation.
Manufacturer’s range
TSK LtdSpecialist insulationWe use and source leading insulation and membrane products for bespoke homes: mineral wool, rigid boards, reflective systems, sheep’s wool and the layers that connect them.
We work with some of the country’s largest insulation manufacturers and suppliers, so we can source just about any insulation product at competitive prices.
Superglass, Knauf Insulation, ACTIS, Thermic Technology, Celotex, Kingspan, Recticel and Glidevale Protect are among the names we use. We also install sheep’s wool insulation and can source other specified materials through our supplier network.

Superglass & Knauf Insulation
We use Superglass glass mineral wool and Knauf Insulation glass and rock mineral wool products. Rolls, batts and slabs allow the specified insulation to be fitted between studs, joists and rafters, as well as in other suitable wall, roof and floor constructions.
Thermal insulation and acoustic insulation have different jobs. We select the intended product, thickness and density with the project specification, then fit it with attention to gaps, edges and continuity.

Celotex · Kingspan · Recticel
Our board ranges include Celotex and Recticel PIR insulation, together with specified Kingspan systems such as Kooltherm phenolic boards. Different products are made for different wall, roof and floor applications.
The complete build-up determines which board is appropriate. Cutting, fitting, junctions, facings and any specified joint treatment all matter when the insulation is installed.

ACTIS & Thermic Technology
We use ACTIS products, including honeycomb and multifoil insulation systems, and Thermic Technology products from the Photon range. These offer different approaches to reflective insulation and associated membrane layers.
The product’s declared performance depends on its intended installation. Air spaces, orientation, compression, laps and connections follow the specified system and the manufacturer’s current guidance.

Sheep’s wool insulation
For clients who want natural fibres in the building fabric, we can source and install sheep’s wool insulation. Rolls and batts are selected for the intended application and the project’s thermal and acoustic brief.
We discuss the chosen product with your design team so that moisture management, required thickness and the rest of the wall, roof or floor construction are considered together.

Glidevale Protect & specified membrane systems
We use Glidevale Protect air and vapour control layers, breather membranes and associated products, alongside relevant ACTIS and Thermic Technology systems. Each layer has a defined position and purpose in the construction.
Compatible tapes, sealed laps and careful connections at floors, roofs and openings bring the membrane strategy together. The material selection follows the agreed airtightness and moisture-control design.
These are some of the manufacturers in our range. Your specification can go further: tell us the product you need and we’ll explore the sourcing options.

Manufacturer’s rangeWe work with some of the country’s largest insulation manufacturers and suppliers, so we can source just about any insulation product at competitive prices. Send the manufacturer, product name or code, thickness, quantities and delivery location. We’ll confirm the current availability, lead time and price.
Yes. Share the current wall, roof and floor specifications with us. We can discuss sourcing and installing the named products within the agreed scope. Any proposed substitution is referred back to the design team before it is agreed.
Different parts of a home may need different products. Thermal targets, acoustic requirements, available space, moisture management and fire requirements all inform the selection. We install the coordinated specification for your project.
