Window, door and conservatory FAQs

Thermalogik is our slimline, multi-chambered outer frame. The name applies only to this one profile but used alone it will not guarantee an ‘A’ rating for thermal performance. The profile was designed to allow our customers to achieve good energy ratings while taking advantage of lower-priced glass options. Improved thermal ratings can be achieved with the remainder of the Eurologik profile suite by using our new PVC-U Thermal Inserts. These products are also multi-chambered and, when inserted into the outer frame, help to reduce thermal transmittance. Whilst ‘A’ ratings can be achieved using any of our other profiles, these new and innovative products allow you to achieve them more competitively.

We have two options for you. The IQ750 lean-to “roof in a box” is readily available at all of our Eurocell branches in modular sizes. It’s available in white, golden oak and rosewood finishes. We also have the Everlite Enduro roof which has a 60mm-thick roof panel with no rafter bars. This is ideal for conservatories, porches or car port applications.

Cavity Closers FAQs

A cavity closer is a critical building component that seals cavities around wall openings and provides a rigid template for bricklaying, and window or door installation.


Cavity closers:

·        Provide a damp-proof course (DPC)

·        Provide a thermal break

·        Prevent damage from condensation

·        Reduce heat loss and CO2 emissions


The cavity closer acts as a seal, preventing water vapour and damp from entering the cavity wall and the building, whilst also preventing heat loss through the gap. They can be used in a range of different construction types, including masonry, timber frame and steel frame systems.
