We strive as a company to be as sustainable as possible and use recycled products wherever possible. For example, Bloc Seal is manufactured using plastic containing 30% recycled content. We continually review new sustainable materials and manufacturing technologies to further reduce our environmental impact.
All Vulcon Construction products are proudly manufactured in the UK to the highest quality standards. Our manufacturers hold certifications for both ISO9001 (Quality Management) and ISO14001 (Environmental Management), ensuring consistent product quality and environmentally responsible manufacturing processes.
Yes, all of our construction products comply with the relevant approved building regulation documents. For more information, please contact our technical team.
As our products are new and innovative, they do not fall under the “harmonised European product standard” so do not require any markings.
Our products are designed by our experienced in-house team in collaboration with independent structural and application engineers, ensuring they meet the relevant Building Regulations and industry standards. Each product undergoes practical testing and independent certification by a UKAS-accredited laboratory to verify its performance, quality and reliability.
DOR CAV
The Dor Cav structural cavity closer is suitable for cavity widths ranging from 75mm to 150mm, making it ideal for a wide range of residential and commercial construction projects.
The Dor Cav should match the width of your door opening or the next available size up. For example, for a 1000mm door opening, you would typically use a 1200mm Dor Cav, which can be easily cut down to size on site for a precise fit.
The Dor Cav is available in 900mm and 1200mm lengths. For wider door openings, multiple sections can be joined together. For example, a 2400mm opening can be accommodated using two 1200mm Dor Cav.
Please refer to our Dor Cav Installation Guide for step-by-step installation instructions, technical guidance and best practice recommendations.
Full installation instructions for the Dor Cav Retro Fit are available in our Dor Cav Installation Guide, which includes guidance for both new-build and retrofit applications.
No. The Dor Cav is designed to be installed beneath the insulation and screed, where it provides structural support. It is not intended to be installed above the insulation at finished floor level.
BLOC SEAL
The Bloc Seal is manufactured to the same dimensions as a standard concrete building block, measuring 440 × 215 × 100mm. This allows it to be easily incorporated into standard masonry construction without requiring any modifications.
The Bloc Seal is supplied as a single block featuring two offset service apertures. This provides four possible pipe positions, as the block can be rotated through 180° and either seal can be fitted into either aperture, giving you greater flexibility during installation.
All blocks come as standard with 1 x 110mm seal for a normal soil pipe and a 1 x custom seal that can be used for any size pipe/duct ranging from 10mm to 110mm. Alternatively, the 1 x custom seal can be left uncut as a blanking plug if not required.
Yes. Additional Bloc Seal custom seals are available to purchase separately. This allows you to replace the standard 110mm soil pipe seal with a second custom seal, giving you two fully customisable seals within a single Bloc Seal.
Please refer to our Bloc Seal Installation Guide for step-by-step installation instructions, technical guidance and best practice recommendations.

INSU CLIP
The Insu Clip is designed to securely retain 25mm PIR insulation where external walls meet the screed, helping to prevent lateral cold bridging. A 25mm PIR insulation board is the thickness typically required to achieve the thermal performance specified in Approved Document L of the Building Regulations. For full product specifications, please see the Insu Clip product page.
No. The thin foam edging strip often supplied with underfloor heating systems is designed to allow for the natural expansion of the screed against surrounding walls. It is not intended to provide thermal insulation or prevent cold bridging.
To comply with the thermal performance requirements of Approved Document L and SAP calculations, 25mm PIR insulation should be installed around all external walls, securely retained using the Insu Clip.
The Insu Clip is available in packs of 20, 50 and 100, making it suitable for projects of all sizes, from small residential developments to larger commercial installations.
Please refer to our Insu Clip Installation Guide for step-by-step installation instructions, technical guidance and best practice recommendations.
You can order the Insu Clip directly through our Shop. If you have any questions about product availability or your particular application, please send an email to sales@vulcon.co.uk or call 01892 251992.
