At Planet Insulation we supply the whole Celotex range: Celotex GA4000 range (which includes the TB4000 and XR4000 products), Celotex PL range (a plasterboard backed board), and Celotex cavity wall insulation. Celotex insulation boards are the ideal product whatever you thermal insulation needs are. Here is a breakdown of the range by function:
The unique Celotex online U-value calculator generates a U-value specific to the chosen construction and enables you to input a range of different construction parameters to evaluate their impact on thermal performance.
Below we look at the three major product ranges: the TB/GA/XR foil backed PIR range, the PL plasterboard backed range, and the CW cavity wall range.
The first thing to make clear is that the Celotex TB, GA, and XR are the same foil-backed PIR boards, but different thickness:
TB: 12mm to 40mm
GA: 50mm to 100mm
XR: 110mm to 150mm
Further, these are the replacement for the TB/GA/XR3000 series, although those names are still sometimes used to mean this product.
These products are comparable with the Kingspan Therma range, and can be used in pretty much any application - from roof to wall to underfloor heating - and is designed to be cut to fit between rafters and joists to achieve a lower U-value than a single layer of insulation would achieve traditionally.
A thermal laminate product featuring 12.5mm tapered edge plasterboard bonded to a high performance, rigid polyisocyanurate (PIR) insulation board, PL4000 reduces installation time by combining thermal insulation and an internal lining in one operation.
Suitable for use in new build and refurbishment projects, PL4000 can be fixed across the face of timber frame studs, or joists and rafters in pitched and cold (ventilated) flat roofs. It can also be fixed to the internal face of existing solid walls or cavity walls to upgrade their thermal performance.
