Construction Materials - TPR

TPR is a synthetic concrete developed as a green technology composite by Affresol with the help of British universities. Manufactured using a unique cold process utilising traceable, non-toxic waste polymers from industry, the product is sustainable, recyclable and supported by The Carbon Trust.

It is estimated that each 6×8 DaylightSECURE saves around 5 cubic meters of raw plastic waste going to landfill – about the same volume as one African elephant!

Extensive tests confirm TPR offers superior strength and flex compared to concrete despite it being 30% lighter. See the tech spec here.

It has low permeability and excellent thermal properties to reduce any risk of condensation and has a Class E fire classification suitable for building construction.

The TPR production facility is in Wales and all panels are individually handmade.

No other building material can equal the collective qualities of TPR and it is now being specified by councils, housing authorities, Network Rail and the MOD as a replacement for steel and concrete buildings.

Kevlar is an amazing para-aramid synthetic fibre manufactured by DuPont. In simple terms that’s a super strong plastic that weight for weight is five times stronger than steel.

Kevlar is available in a number of forms; as a composite it is used in the manufacture of Formula 1 car bodies, helicopter blades and extensively in the aerospace industry.

In a knitted form it is used for anti-stab and bullet-proof vests by police and military units worldwide and in many products that require high tensile strength combined with resistance to abrasion and heat.

Brodco uses a full layer of Kevlar in the production of the composite Max Strongroom roof.  Kevlar® is a registered mark of DuPont.

Construction Fixings

Screwbolts are a large self-tapping screw with a hexagon head manufactured for joining and securing TPR panels. They are made from 8.8 hardened steel and coated with black zinc, providing double the resistance to salt spray compared to standard zinc coating.

Stainless steel 80mm coach screws are used to secure the roof to the wall panels. The coach screws will not rust and provide long term security.


DuraPass and DuraTherm are premium insulated British doors manufactured for Brodco by Garage Door Systems of Northern Ireland in a range of colours and sizes.
