Ensure your loft doesn’t allow cold air to penetrate through ventilated eaves and also stop heat escaping through open penetrations in the main living spaces.
Covering your loft with a 300mm layer of loft insulation will reduce heat loss in your home by 30%
With next day appointments available and installations completed within hours, you can have your loft insulated within 48hours!
An automatic benefit of your loft’s insulation is a higher rating for your home’s Energy Performance Certificate.
Fibreglass Loft Roll
Whilst fibre-based loft roll isn’t an airtight insulator, at 300mm in thickness, it will provide adequate thermal performance to meet current regulations. Laid between floor joists with a layer above running in the opposite direction, a total coverage of the loft floor will help to reduce heat loss by up to 30%. Although you can install loft insulation as a DIY project, for best results and warranties, using a PAS2035 accredited company will give you the peace of mind that your insulation will work to its full potential. Loft insulation can help to make your home warmer in the winter and cooler in the summer.
This thin layer of perforated aluminium foil is designed to protect the loft insulation from the impact of solar gain during the summer and cold draughts during the winter. The perforations to the foil layer means that moisture from within the home can escape into the loft where natural ventilation will disperse moisture laden air. The radiant barrier is an innovative way to increase the potential performance of your loft insulation by up to a further 15-20% and it’ll work year round to make a noticeable difference in other summer and winter. Extremely cost effective to buy and can be installed as a DIY project or optional extra to a loft insulation install.
Raised loft boarding is the best way to maintain some usable storage space within the loft whilst enabling room for insulation underneath. With many lofts in the UK already boarded without an adequate layer of insulation on the loft floor, we recommend raising the boards on what is known as loft legs and creating a raised platform for storing belongings. We offer a full loft boarding service as a part of any insulation install, leaving you with the peace of mind that your insulation and loft floor are properly fitted to regulations. Generally loft boarding will be focussed around the central section of a loft.
The main difference between spray foam insulation and more traditional forms of insulation like fiberglass or cellulose is that spray foam insulation is an air barrier and thermal barrier all in one (with closed cell spray foam even offering a moisture barrier as well). This means that spray foam insulation does the job of providing insulation and air sealing with one product, whereas traditional forms of insulation do not provide any barrier to the flow of air. This is important for establishing a continuous and complete thermal/air barrier with the building envelope.
There are two distinct types of spray foam insulation: open cell and closed cell. Closed cell spray foam cures into a hard, rigid state whereas open cell cures with a spongy, softer feel to it. In terms of R-values, closed cell spray foam is close to R-7 per inch and open cell around R-4 per inch. Also, closed cell becomes an air barrier at only 1” of application, while it takes on average 3” of open cell foam to achieve an air barrier. Another big difference in the two is that open cell is water permeable and closed cell is not. Open cell also has soundproofing qualities that can help in dampening outside noise.
