Energy Saving


Bradfords provide a range of energy saving products from tubular rooflights, to Solar Heating and energy systems, to naturally produced insulation.

Velux Sun Tunnel

  • Many houses have bathrooms, hallways and other rooms where daylight only enters when you open the door. Dim and dark, these rooms are unwelcoming places until you turn on the light.

    Now that has all changed.

    VELUX Sun Tunnel signals the end of dim and dismal spaces in the home. VELUX Sun Tunnel brings natural light into even the darkest and most isolated spaces through a specially designed tunnel from roof to ceiling.

    • Owing to the dark-coloured, flat, square frame and flashing in polyurethane and its clear and robust glass, the VELUX Sun tunnel goes well with any roof, in the same style as VELUX roof windows.

    The attractive and discreet ceiling diffuser unit with its acrylic pane melts into the ceiling, spreading a soft and restful light throughout the room. The tunnel between the roof and the diffuser is 35 cm in diameter and takes up a minimum of space in the loft.

    Solar Heating Water Heating Systems

    Although we can supply both flat plate and evacuated tube panels , we only recommend evacuated tube. Navitron evacuated tube panels are twice as efficient at collecting heat as flat plates used by some companies. Evacuated  tube technology produces heat in diverse weather conditions making them perfect for the British climate. Although they are far more expensive to manufacture than flat plate panels , they will give you more months of free hot water every year, so will pay for themselves far more quickly.

    Insulation - Thermafleece

    Sheep’s Wool Insulation – Thermafleece – Second Nature UK Ltd
    Thermafleece is a natural home insulation material that uses the blended wool of British hill sheep. It is breathable so can absorb moisture with no loss of thermal efficiency, keeping the house warm in winter and cool in summer. The production of Thermafleece takes considerably less energy than is required to produce glass fibre insulation. It is completely safe to handle and will remain effective for the life of the building, and is then biodegradable and recyclable. Thermafleece is treated with a natural fire–proofing agent and is also treated to protect against mould and insects.

    Water Turbines

    If you are lucky enough to have a water course across your property ,Navitron can usually provide a water turbine which will allow you to generate a significant proportion of your electricty needs. Please contact us for further information.

    Wind Turbines

    We are able to supply a variety of wind turbines from 200w upwards. Please contact us for further information.

    Solar PV

    We sell a range of photovoltaic modules (PVs) ranging from 5W up to 160W. Available to order we can provide panels from 5W and upwards in increments of 5W. Our Solar Panels are very attractively priced, but at the same time maintain high quality levels. We use large aluminium sections for the module frame, which provides excellen rigidity - much better than most of the well-known names in the industry. Electrical connections are located in a small waterproof electrical box at the back of the panel, and larger panels are provided with quick-fit outdoor high-voltage connectors as standard, making wiring up strings a piece of cake. These panels are suited to both small scale, low voltage battery-based installations as well as larger grid-tie (grid-connect) systems. Navitron is also able to provide charge controllers/ regulators for PV systems, Grid tie inverters and mounting systems for PV

    Insulation - Thermafleece PB20

    Thermafleece PB20 is as a lower density, compressed roll insulation that is easy to handle and install in confined spaces such as lofts. Thermafleece PB20 contains a lower quantity of wool than Thermafleece (60% compared to 85%).

    Because Thermafleece PB20 is compress packed, it is necessary to incorporate a proportion of recycled polyester fibres to ensure the insulation regains its full thickness when un-rolled. Compressing the rolls by approximately 60% significantly reduces the impact of transporting the finished product and nearly halves the required storage space for the same volume of insulation.

    PB20 has a thermal conductivity of 0.039 W/mK and is available in roll form in widths of 370mm and 570mm to enable quick and easy installation. Each roll contains a single 5.3m length of insulation and is available in a thickness of 55mm, 70mm and 100mm

    Insulation - Superglass Multi- Roll 44

    Multi-roll 44 is a mineral wool roll which is lightweight , flexible , resillent and non-combustable.

    It is available in a range of thicknesses and may be split into any of four widths as required.

    It is CFC and HCFC free , wil not rot , degrade or sustain vermin ,will not encourage the growth of mould , bacteria or fungi and can be described as non-hygroscopic.

    Insulation - Rockwool

    Rockwool Roll is a medium density multi-application insulation mat. This versatile Roll is suitable for thermal insulation of roof spaces in domestic, commercial and industrial buildings. It is also useful for improving the acoustic performance of suspended ceilings. Roll is produced in 1200mm width. The packaging provides cutting guidelines should the product be required in 400mm or 600mm widths. By cutting through the product with a long serrated blade, this will ensure the material can be cut to the desired widths. Alternatively, Rollbatt is supplied pre-cut to 400mm (x3) or 600mm (x2) widths
