Solid roof. A product we can offer to DIY, trade and retail.

Why do you need a Solid Roof?

Roofing from Highseal Manufacturing CompanyOur Solid Roof provides year-round comfort to enhance the enjoyment of your conservatory.  It will keep your room cosy and warm in the winter but cool and comfortable in the summer, and will reduce the noise generated by rain.  It can improve privacy thus preventing neighbours seeing into your personal space.  Wood outperforms Aluminium or Steel for thermal efficiency as it is not a thermal conductor, it is therefore less likely to condensate and will be at least 5 times more energy efficient than traditional glazed conservatory roofs, resulting in reduced energy bills.


Can be personalised inside and out. Internally the roof can be plastered, the most popular finish, or cladded with timber and pvc.  Roof vents are also available for added light and ventilation.  These come with a 10-year guarantee, slimline wooden frame design, lacquer coating and toughened outer glass.


Externally you can choose from a range of coloured lightweight tiles and slates from Metrotile and Tapco, both of which have BBA accreditation, weatherproof performance and a guarantee against corrosion, warping, fading and cracking. 

The roof is made pre-assembled in our factory and then dis-assembled and taken to site.  This helps to minimise disruption to the client, maximises efficiency on site, ensures design accuracy, and provides fast installation, which in turn helps to reduce the time the conservatory is left open.  


The roof pods are a boarded one-piece timber framework section, either shaped or rectangular, which forms a structural link.  All pod joints are glued and screwed together before being boarded with 18mm OSB roofing sheets.  A 90mm thick multi layer of Hybris foam and foil backed insulation is fitted into the pods before they are bolted together to secure the installation.  A 19-layer vapour barrier is then added and fitted across the underside of the roof.  This provides further insulation as well as air and watertight seals to prevent both air leakage and moisture passing through the roof (eliminating the risk of condensation).


The outside of the pods are covered with a waterproof air permeable breather membrane which lies below the tiles.  2 x 2 battens are fitted internally to create a further air gap, allowing 12.5mm foil backed plasterboard ready for a typical 2.5mm skim finish.  The one-piece roof pods are then glued and screwed onto a continuous Glulam (glued laminated timber) ring beam which is attached to the head of the window frames, finished with a 150mm fascia board and an "ogee" decorative gutter system.  The engineered beam provides incredible structural strength, and long-term durability and performance.

U- Value of 0.18

U-value is a measure of heat loss. It is expressed in W/m2k and shows the amount of heat loss in watts per square metre of material when the temperature outside is at least one degree low. The lower the u-value, the better the insulation provided by the material.
