Frequently Asked Questions
Can Isover CWS be used in masonry cavity walls below the DPC level?
Because ISOVER CWS is made with a water-repellent binder, it may be used safely below the DPC level in masonry cavity walls without the risk of ground moisture crossing the DPC via capillary action.
Can ISOVER Spacesaver be implemented in a vertical or slanted application?
Because ISOVER Spacesaver is a low-density loft insulation roll, we recommend it solely for horizontal applications because it may not self-support in any sloping or vertical application.
When placing PIR beneath a concrete slab or screed, do I need to use membranes?
First and foremost, make sure that the PIR insulation boards are installed above the damp proof barrier (DPM). Wet screed or wet concrete may damage the foil facings of our PIR insulation boards, allowing gas to escape and weaken the floor topping, so we always recommend a membrane be used for protection over the PIR insulation boards once they have been laid and prior to the screed or concrete topping being poured.
Is it necessary for me to wear PPE when installing your insulation products?
Our safety data papers outline the procedures must be performed while installing our MW or PIR insulation materials.
Is your insulation an attraction for rats or other vermin?
Our insulation provides little nutritional benefit to vermin, but if rats gain access to it, they may utilise it as a nest.
How should PIR products be stored?
Our PIR insulation boards should be stored in their original packaging, out of the elements, and away from the ground. Wet or damaged boards (e.g., smashed corners) should not be utilised. For any further queries please contact our Technical Support Centre.
Once installed, how long will your insulation last in my building?
Once placed, we can claim that the insulation will function throughout the estimated lifespan of the building into which it is installed, which is commonly assumed to be 60 years if left unmolested and undisturbed.
What is a Euroclass ‘reaction to fire’ rating?
A 'reaction to fire' grade from Euroclass describes how a product behaves when exposed to a direct ignition source. The behaviour is graded from A1 to F, with A1 achieving the highest degree of performance and F achieving the lowest level of performance.
What is PAS 2030 accreditation?
PAS 2030 is a standard for installing energy-saving measures in existing buildings. PAS 2030 contains installation, process management, and service providing standards. It also comprises installation procedures, equipment, tools, product or system selection, and material appropriateness requirements. PAS 2030 also addresses the commissioning of installed measures, as well as the training, skills, and competence of those doing such installations. Contractors performing work under the Green Homes Grant must be TrustMark registered, which necessitates PAS 2030 certification. The framework was created in response to the Each Home Counts (Bonfield) evaluation, which discovered that many energy efficiency and renewable energy retrofit projects lacked quality and performance. It specifically addressed the problem that many such improvements were frequently carried out without due care for the property and its tenants. PAS 2030 has been redeveloped after its first publication, and we are presently in the transition period between PAS 2030:2017 and PAS 2030:2019. As a result, contractors that already have a certification can register with TrustMark using any version of PAS 2030. However, moving to PAS 2030:2019 as soon as possible is advised. Contractors who were not certified to a PAS 2030 standard prior to the scheme's implementation will be required to work toward PAS 2030:2019 certification.
What is the best way to cut Mineral Wool or PIR insulation?
Insulation saws and knives are generally accessible; use them to trim or cut our insulation materials as needed.
